Before introducing embodiments of the present application, some key terms will first be described.

The shift delay may refer to the period of time from when the camera shutter is pressed to when the camera starts exposure. The duration of this period is not fixed.

Based on the continuous enhancement of convenience of photographing devices (such as smartphones, video cameras, digital cameras and other devices for photographing) and image systems thereof, the photographing use frequency of users in daily life is increasing. But there may be a case where the sheeting fails when the user photographs with the photographing apparatus.

Taking a smart phone as an example, users often use the smart phone to shoot under various extreme scenes (such as a medium-low bright night scene, indoor extremely dim light, a sunset, a magnesium light court, and the like). When shooting in these extreme scenes, the processing time of the shooting algorithm is longer than the processing time of the Shutterlag (shutter delay), and the user can have the condition of hand shake when holding the shooting for a long time, or the user can put down the mobile phone too quickly to finish shooting and other habits, so that the shooting failure is caused.

Thus, it is necessary to determine the sheeting rate. For example, the film rate of the photographing apparatus may be determined, and based on the film rate of different photographing apparatuses, the photographing imaging effect of the different photographing apparatuses may be known or verified.

Determination of the failure rate of taking a picture the rate of taking a picture can be determined manually, but this implementation is time-consuming and labor-consuming. Moreover, the mode of manually evaluating whether the film forming fails or not has stronger subjectivity, and is inconvenient for objectively and accurately determining the film forming rate.

In the following, some possible application scenarios of the embodiments of the present application are described.

Application scenario 1: the method can compare the film forming rate of different smart phones, and determine which smart phone has better film forming effect (or called photographing imaging effect).

Application scenario 2: the method can compare the smart phone sheeting rates of different factories and determine which manufacturer has better smart phone sheeting effect.

Application scenario 3: the method can compare the film forming rate of different versions of the operating system (or different manufacturer operating systems) to determine which version of the operating system (or which manufacturer operating system) has better film forming effect.

Application scenario 4: the current smart phone's rate of tablets can be known. It may also be determined whether the measured sheeting rate meets the expected sheeting rate in combination with the expected sheeting rate requirement.

Application scenario 5: the film forming rate of different photographing modes can be compared to determine in which photographing mode the currently tested smart phone has better film forming effect.

Application scenario 6: the sheeting rate of a certain configuration item may be compared to determine whether the comparison meets expectations.

The configuration item may be configuration information of any one of an illumination environment in which the photographing apparatus is located, a shake mode of the photographing apparatus, a zoom magnification of the photographing apparatus, an apparatus type of the photographing apparatus, an operating system version of the photographing apparatus, a photographing mode of the photographing apparatus, and the like. For example, the configuration information of the illumination environment may be a bright light environment, a dark light environment, etc. If desired, the resulting test data may be used to determine other application scenarios for the film rate (e.g., application scenarios 1-5 described above).

The embodiment of the present application is not limited to the above-listed application scenarios, and may be applied to other feasible application scenarios not shown in the present embodiment.

Next, the technology of the embodiment of the present application will be described.

As shown in fig. 2, an embodiment of the present application provides a method for determining a film rate, which may include the following steps 201 to 204. The execution subject of the method can be electronic equipment such as personal computers, smart phones, servers and the like.

For example, in one embodiment, the first scene information includes the following configuration items: bright light environment, high frequency dithering, main camera, equipment manufacturer X, operating system version X, night scene mode.

For another example, in another embodiment, the first scene information includes the following configuration items: dim light environment, low frequency jitter, main shot, night scene mode.

In the following, some configuration categories affecting imaging quality are explained, respectively.

1) For the lighting environment this configuration class:

For example, in the context information, the configuration information of the configuration category may relate to light intensity, light color, shooting angle, and the like.

Taking the effect of light intensity on imaging quality as an example, in one embodiment, the configuration information for the configuration class may be bright light (or intense light), dark light (or weak light). Therefore, at least two photographing scenes can be preset, the illumination environment of one photographing scene is a bright light environment, and the illumination environment of the other photographing scene is a weak light environment.

The light source sequence can be preset, and different illumination environments can be obtained through switching of the light sources in the light source sequence.

2) For the dither pattern this configuration class:

the above configuration items may include configuration information of a configuration category of the shake mode of the photographing apparatus in consideration of the influence of different shake modes on the imaging quality. For example, in the context information, the configuration information of the configuration category may relate to jitter frequency, jitter amplitude, and the like.

Taking as an example the effect of the dithering frequency on the imaging quality, in one embodiment the configuration information of the configuration class may have a high frequency, a low frequency. Thus, at least two photographing scenes can be preset, wherein the dithering mode of one photographing scene is high-frequency dithering, and the dithering mode of the other photographing scene is low-frequency dithering.

The jitter sequence may be preset, and the different jitter modes may be obtained by switching the jitter modes in the jitter sequence.

3) For this configuration category of zoom magnification:

Illustratively, in the context information, the configuration information of the configuration category may relate to vendor, model, etc.

Taking the influence of the vendor of the smart phone on the imaging quality as an example, in one embodiment, the configuration information of the configuration class may be vendor 1 and vendor 2. Thus, at least two photographing scenes can be preset, wherein the equipment type of one photographing scene is the smart phone of manufacturer 1, and the equipment type of the other photographing scene is the smart phone of manufacturer 2.

For switching of different shooting devices, the shooting devices can be manually switched, and the corresponding control system can also be used for automatically switching the shooting devices.

In one embodiment, when the shooting device is manually switched, the scene information may also include configuration information of a configuration category of a device type. In this case, the electronic device may read the device information of the current photographing device and verify whether the current photographing device matches with the configuration information of the configuration class, which is the device type, in the current scene information. If so, triggering the shooting equipment to execute shooting operation. If the two types of the shooting equipment are not matched, prompt information can be output to prompt that the used shooting equipment does not accord with the current scene information, so that a user can manually replace the correct shooting equipment.

In other embodiments, when the photographing device is manually switched, the scene information may not include configuration information of the device type, that is, the electronic device defaults to the current photographing device.

5) This configuration class for operating system version:

the configuration item may include configuration information of a configuration class of an operating system version of the photographing apparatus in consideration of influence of different operating system versions on imaging quality. Illustratively, in the context information, the configuration information of the configuration category may have version 1, version 2, and the like. Version 1 and version 2, etc. may be versions of different operating systems that are installable on the same capture device. For example, version 1 is the version number of the operating system that was developed before, and version 2 is the version number of the operating system that was developed after.

For switching of different operating system versions, the switching can be performed manually or automatically by a corresponding control system.

For version switching, the version of the operating system can be updated for the same shooting device to realize version switching, or two shooting devices of the same type, in which operating systems of different versions are respectively installed, can be directly switched to realize version switching.

In one embodiment, when the version is manually switched, the scene information may also include configuration information of the configuration type of the operating system version. In this case, the electronic device may read the operating system related information of the current photographing device, and verify whether the operating system related information matches with the configuration information of the configuration category of the operating system version in the current scene information. If so, triggering the shooting equipment to execute shooting operation. If the operation system version does not accord with the current scene information, a prompt message can be output to prompt the user to manually replace the correct operation system.

In other embodiments, when the version is manually switched, the scene information may not include configuration information of the configuration type of the operating system version, that is, the electronic device defaults to the current operating system installation without errors.

6) For the photographing mode, this configuration category:

the configuration item may include configuration information of a configuration category of a photographing mode of the photographing apparatus in consideration of influence of different photographing modes on imaging quality. For example, in the scene information, the configuration information of the configuration category may include a portrait photographing mode, a night scene photographing mode, and the like.

Based on the above, at least two photographing scenes can be preset, wherein the photographing mode of one photographing scene is a portrait photographing mode, and the photographing mode of the other photographing scene is a night scene photographing mode.

The scene information used for configuring the photographing scene may be any combination of the configuration information of the six configuration categories, and the specific combination mode may be selected as required.

For example, in one embodiment, the scene information may include configuration information of configuration categories such as an illumination environment in which the photographing apparatus is located, a shake mode of the photographing apparatus, a zoom magnification of the photographing apparatus, an apparatus type of the photographing apparatus, an operating system version of the photographing apparatus, and a photographing mode of the photographing apparatus. This embodiment can be applied at least to any one of the application scenarios 1 to 6 described above.

For example, in another embodiment, the scene information may include configuration information of configuration categories of an illumination environment in which the photographing apparatus is located, a shake mode of the photographing apparatus, a zoom magnification of the photographing apparatus, and a photographing mode of the photographing apparatus. This embodiment can be applied at least to any one of the application scenarios 1 to 6 described above.

The configuration category related to the scene information can be set as required, and the embodiment is not limited thereto, and other possible examples are not described herein.

Illustratively, in one embodiment, taking an example in which the scene information includes information of an illumination environment in which the photographing apparatus is located and information of a shake mode (specifically, a shake frequency) of the photographing apparatus, one or more of the following scene information 1 to scene information 4 may be preset:

scene information 1: a bright light environment, high frequency dithering pattern;

scene information 2: a bright light environment, a low frequency dithering pattern;

scene information 3: a dim light environment, high frequency dithering pattern;

scene information 4: dim light environment, low frequency dither pattern.

The configuration information of other configuration categories (such as jitter amplitude, photographing mode, etc.) in the scene information is consistent, for example, the configuration information is all default values.

In this embodiment, each piece of preset scene information may be used as the first scene information, so that an image corresponding to each piece of scene information may be obtained.

In one implementation, the film rate of the photographing apparatus may be calculated based on images corresponding to the scene information.

In another implementation, the sheeting rate for the bright light environment may be calculated based on the images corresponding to scene information 1-2, and the sheeting rate for the dark light environment may be calculated based on the images corresponding to scene information 3-4.

In a possible further implementation, the cropping rate of the corresponding high-frequency dither patterns may be calculated based on the images corresponding to the scene information 1, 3, and the cropping rate of the corresponding low-frequency dither patterns may be calculated based on the images corresponding to the scene information 2, 4.

For example, in another embodiment, taking as an example that the scene information includes information of an illumination environment in which the photographing apparatus is located, information of a shake mode of the photographing apparatus (specifically, a shake frequency), and information of an apparatus type of the photographing apparatus (specifically, a manufacturer of the apparatus), one or more of the following scene information 5 to scene information 12 may be preset.

Scene information 5: a bright light environment, a high frequency dithering mode, vendor 1;

scene information 6: a bright light environment, a low frequency dithering pattern, vendor 1;

scene information 7: dim light environment, high frequency dithering mode, vendor 1;

scene information 8: dim light environment, low frequency dithering mode, vendor 1;

scene information 9: a bright light environment, a high frequency dithering mode, vendor 2;

scene information 10: a bright light environment, a low frequency dithering pattern, vendor 2;

scene information 11: dim light environment, high frequency dithering mode, vendor 2;

scene information 12: dim light environment, low frequency dither pattern, vendor 2.

When the first scene information is any one of the scene information 5 to the scene information 8, one or more shooting devices of the manufacturer 1 are used for executing shooting operation, and when the first scene information is any one of the scene information 9 to the scene information 12, one or more shooting devices of the manufacturer 2 are used for executing shooting operation.

In one possible implementation, the film rate of the photographing apparatus of vendor 1 may be calculated based on the images corresponding to the scene information 5 to the scene information 8, and the film rate of the photographing apparatus of vendor 2 may be calculated based on the images corresponding to the scene information 9 to the scene information 12.

Step 202, acquiring a first image shot by a shooting device in a first shooting scene.

The first shooting scene is configured according to the first scene information, and a first image shot in the first shooting scene corresponds to the first scene information. The images may be stored in a classified manner according to scene information corresponding to the images.

In one embodiment, taking a photographing device such as a smart phone as an example, a personal computer connected with the smart phone may configure a corresponding photographing scene according to scene information, and after the photographing scene is configured, trigger or control the smart phone to perform photographing operation, and obtain an image photographed by the smart phone. When the intelligent mobile phone executes shooting operation in a first shooting scene, the personal computer can obtain a first image corresponding to first scene information.

For the execution of photographing operations, a preset number of photographing operations can be executed in the current photographing scene, and the preset number of images are correspondingly obtained. The preset number is a positive integer, for example, can be set to 1, 5, 10, 50, etc. as required, which is not limited in this embodiment.

In step 203, imaging quality information of the first image is acquired, wherein the imaging quality information is used to reflect the imaging quality of the image.

Reflecting the imaging quality, or measuring the imaging quality, measuring the imaging picture quality.

In one embodiment, the imaging quality information may include at least one of sharpness and ambiguity (such as MotionBlur).

The definition can be used for reflecting the definition degree of each detail texture and the image edge of the image.

MotionBlur, motion blur, can be used to reflect the degree of blur of a moving scene in an image.

In one embodiment, the sharpness of the image may be calculated using a gradient operator based contour extraction method.

Step 204, determining a first film forming rate according to the imaging quality information of the first image.

The film rate may be, for example, the probability that a captured image is available.

In one embodiment, the first film rate may be a film rate of the photographing apparatus.

In another embodiment, the first film forming rate may be a film forming rate of a manufacturer of the corresponding photographing apparatus.

In yet another embodiment, the first film rate may be a film rate corresponding to an operating system version of the photographing apparatus.

In still another embodiment, the first clip rate may be a clip rate corresponding to any configuration item in the first scene information.

For example, if the first scene information includes information of an illumination environment where the photographing apparatus is located, the information is a dark light environment, and the first film forming rate may be a film forming rate corresponding to the dark light environment.

For another example, if the first scene information includes information of a dither pattern of the photographing apparatus, the information being a dither pattern, the first film forming rate may be a film forming rate corresponding to the dither pattern.

For another example, if the first scene information includes information of a zoom magnification of the photographing apparatus, the information is a main shot, the first film rate may be a film rate corresponding to the main shot.

For another example, if the first scene information includes information of a photographing mode of the photographing apparatus, the information is a portrait mode, the first film forming rate may be a film forming rate corresponding to the portrait mode.

In one embodiment, taking the imaging quality information as definition as an example, the definition of the first image may be compared with a preset definition threshold, and if the definition of the first image reaches the definition threshold, the first image may be considered to be usable, otherwise, the first image may be considered to be unusable. And further, the film rate can be calculated based on the total number of images and the number of clearly available images. For example, the sheeting rate may be the number of available images as a percentage of the total number of images.

The method for determining the film forming rate can objectively and automatically determine the film forming rate of the shooting equipment in a whole process, so that the problem of time and labor consumption when the film forming rate is determined manually is solved.

Considering that the photographing apparatus has a corresponding manufacturer, has a corresponding apparatus model, and is provided with an operating system of a specific version, the first cropping rate determined in this embodiment may be not only the cropping rate of the photographing apparatus, but also the cropping rate of the apparatus model of the photographing apparatus, the cropping rate of the manufacturer corresponding to the photographing apparatus, and the cropping rate of the operating system version corresponding to the photographing apparatus.

In order to achieve the purpose of obtaining the filming effect of different filming devices, the filming effect of filming devices of different manufacturers, the filming effect of filming devices of different models of the same manufacturer, or the filming effect of different operating system versions, in one embodiment, referring to fig. 3, the method for determining the filming rate shown in fig. 2 may further include the following steps 301 to 306:

step 301, configuring a second shooting scene according to second scene information, wherein the second scene information comprises configuration items affecting imaging quality.

The configuration items included in the first scene information and the configuration items included in the second scene information may be identical, may be partially identical, or may be completely different.

The category of the configuration item included in the first scene information and the category of the configuration item included in the second scene information may be identical, may be partially identical, or may be completely different.

Step 302, acquiring a second image shot by the shooting device in a second shooting scene.

The second shooting scene is configured according to second scene information, and a second image shot in the second shooting scene corresponds to the second scene information.

In step 303, imaging quality information of the second image is acquired.

Step 304, determining a second film forming rate according to the imaging quality information of the second image.

In step 305, the first film forming rate and the second film forming rate are compared to obtain a comparison result.

And step 306, outputting a comparison result.

The steps of acquiring the first image and the second image may be performed sequentially, and the imaging quality information of the images may be calculated together, so as to determine the film rate and compare the film rate. Or the first image can be acquired to determine the first film forming rate, and the second image can be acquired to determine the second film forming rate, so that the film forming rates can be compared. The sequence of execution of these steps is not limited in this embodiment.

In one embodiment, the photographing apparatus that performs the photographing operation in the second photographing scene is the same apparatus as the photographing apparatus that performs the photographing operation in the first photographing scene.

For example, when the first film rate is the film rate of one photographing mode and the second film rate is the film rate of another photographing mode, the two photographing devices may be the same device or different devices.

The same equipment may be the same equipment, or may be different equipment in the same production batch.

In another embodiment, the photographing apparatus that performs the photographing operation in the second photographing scene is a different apparatus from the photographing apparatus that performs the photographing operation in the first photographing scene.

For example, when the first cropping rate is the cropping rate of one shooting device and the second cropping rate is the cropping rate of another shooting device, the two shooting devices are different devices.

The first scene information and the second scene information may be part or all of a plurality of scene information set in advance.

The embodiment can automatically compare the first film forming rate with the second film forming rate and output a comparison result for the user to check. For example, taking the first rate as the rate of the smart phone 1 and the second rate as the rate of the smart phone 2, the first rate is greater than the second rate, and the comparison result may be that "the effect of the smart phone 1 is better than the smart phone 2", "the rate of the smart phone 1 is greater than the rate of the smart phone 2", and so on.

In other embodiments, the first and second rates may also be directly output for viewing by the user.

For example, in order to obtain the filming effect of the filming devices of different factories (the factories 1 and 2), the filming rate of the filming device of the factory 1 is obtained by photographing based on the filming device of the factory 1, and then the filming rate of the filming device of the factory 2 is obtained by photographing based on the filming device of the factory 2. Based on the obtained sheeting rate, the sheeting effect of the shooting equipment of the two factories can be compared.

Based on this, the first scene information may be, for example, any one of the above-described scene information 5 to 8, and the second scene information may be any one of the above-described scenes 9 to 12.

Since a certain version of operating system is installed in the photographing apparatus, in order to obtain the film effect of different operating system versions, in one implementation manner, the operating system version may be switched by switching the photographing apparatus. In this case, for switching photographing apparatuses, the apparatuses to be switched may be the same kind of apparatuses, and differences between different apparatuses may be basically only different from operating system versions installed on the apparatuses than apparatuses of the same model and the same production lot, so that the switching photographing apparatuses are equivalent to switching operating system versions.

In another implementation, the operating system version may also be switched by updating the operating system based on the same shooting device.

In step 202, the embodiment configures a corresponding first shooting scene according to the first scene information, and the image shot in the first shooting scene corresponds to the first scene information. According to the scene information corresponding to each shot image, the images can be classified and stored, so that operations such as film rate analysis, image effect verification, image related data viewing and the like can be performed on demand based on the classified and stored images.

As such, in one embodiment, the method for determining a film rate shown in fig. 2 may further include: classifying and storing the first image according to the first scene information corresponding to the first image;

the determining the first film forming rate according to the imaging quality information of the first image comprises the following steps: and determining the first film forming rate according to the imaging quality information of the first image and the imaging quality information of other images in the class of images comprising the first image.

The embodiment of the application can record the corresponding scene information of the image when the image is stored. Based on this, the stored images may be classified as needed according to various configuration items in the scene information.

Taking configuration information of a device type as an example, assuming that the configuration information of the device type includes the device 1 and the device 2, according to the configuration information of the device type in the scene information corresponding to the image, all images corresponding to the device 1 and all images corresponding to the device 2 can be separated, then the film forming rate of the device 1 is determined according to all images corresponding to the device 1, the film forming rate of the device 2 is determined according to all images corresponding to the device 2, and then the film forming rates of the two devices are compared to determine which device has better film forming effect.

Taking configuration items including configuration information of illumination environments as an example, assuming that the configuration information of the illumination environments has bright light and dark light, all images corresponding to the bright light and all images corresponding to the dark light can be separated according to the configuration information of the illumination environments in the scene information corresponding to the images, then the film forming rate under the bright light is determined according to all images corresponding to the bright light, and the film forming rate under the dark light is determined according to all images corresponding to the dark light.

Illustratively, the sheeting rate under bright light and the sheeting rate under dark light may be compared to determine whether the comparison meets the expected requirement (assuming the expected requirement is that the sheeting rate under bright light is higher than the sheeting rate under dark light, and a minimum difference in sheeting rate may be required). If the image meets the expected requirement, the image is verified to pass, and the image can be compared with the film forming rate of different shooting devices, the film forming rate of different types of shooting devices and the like according to the images. Based on the comparison of the film forming rate of different devices, the film forming effect of which device can be accurately determined.

For example, if the difference between the sheeting rate in bright light and the sheeting rate in dark light is smaller than expected for the same photographing apparatus, the photographing apparatus can be considered to better cope with, improve the problem of poor sheeting effect in dark light.

Taking configuration information of a photographing mode as an example, assuming that the configuration information of the photographing mode includes a portrait photographing mode and a night scene photographing mode, all images corresponding to the portrait photographing mode and all images corresponding to the night scene photographing mode can be separated according to the configuration information of the photographing mode in the image corresponding scene information, then the film taking rate of the corresponding portrait photographing mode is determined according to all images corresponding to the portrait photographing mode, and the film taking rate of the corresponding night scene photographing mode is determined according to all images corresponding to the night scene photographing mode.

For example, the film taking rate in the two photographing modes may be compared to determine in which photographing mode the current photographing apparatus has better film taking effect.

It can be seen that, according to the method for determining the film rate provided in this embodiment, the film rate of different photographing apparatuses may be determined, and the film rate of other configuration categories may be determined, for example, the film rate in different lighting environments, the film rate in different photographing modes, the film rate in different dithering modes (specifically, the film rate in different dithering frequencies, the film rate in different dithering amplitudes, etc.), and so on.

In order to obtain the film rate of the current shooting device, the images may be classified and stored according to different shooting devices according to the scene information corresponding to the shot images.

In another implementation manner, the scene information corresponding to each image may not be known and recorded, and as long as the images obtained during the photographing of the same photographing device are all classified into the same class based on the photographing device, the class of images is the image corresponding to the photographing device.

Based on this, in one embodiment, the method may further comprise: classifying the first image into a first image set corresponding to the photographing device in step 202, where the first image set further includes images photographed by the photographing device under other photographing scenes;

In this embodiment, in the image set of the same photographing apparatus, there may be respective images photographed by the photographing apparatus in more than one photographing scene.

If there is only one photographing scene, i.e. the first photographing scene, the steps 201 to 202 are executed to obtain images photographed by the current photographing device in the first photographing scene, where the images are all classified into the same image set corresponding to the photographing device. Further, in step 204, the film rate of the photographing apparatus may be calculated according to the definition of some or all of the images in the image set corresponding to the photographing apparatus.

For example, if there are two photographing scenes, i.e., the first photographing scene and the second photographing scene, the steps 201 to 202 may be executed for the scene information corresponding to the two photographing scenes, respectively, so as to obtain the images photographed by the same photographing device under the respective photographing scenes, where the images are all categorized into the same image set corresponding to the photographing device. Further, in step 204, the film rate of the photographing apparatus may be calculated according to the definition of some or all of the images in the image set corresponding to the photographing apparatus.

In this embodiment, a plurality of photographing scenes (including the first photographing scene and the second photographing scene) may be set to basically achieve a full-coverage effect of the scenes, and the film rate is determined under the condition of covering the full scene, so that accuracy and persuasion for evaluating the film rate may be improved.

Possibly, in combination with configuration items (such as configuration information of illumination, shake, etc.) affecting the imaging quality, one or more photographing scenes may be preset. The shooting operation can be performed to shoot images in each preset shooting scene.

In one implementation, only one photographing scene may be set, and one or more images may be photographed under the same photographing scene.

In another implementation, multiple photo scenes may be provided, which may substantially cover most or all of the photo scenes in reality. One or more images may be taken in the same scene.

In one embodiment of the present application, referring to fig. 4, the method for determining a film rate shown in fig. 2 may further include the following steps 401 to 404:

step 401, configuring a third shooting scene according to third scene information, wherein the third scene information includes configuration items affecting imaging quality.

The configuration items included in the first scene information and the configuration items included in the third scene information may be partially the same or may be completely different.

In step 402, a third image captured by the capturing device in a third capturing scene is obtained.

The third shooting scene is configured according to third scene information, and a third image shot in the third shooting scene corresponds to the third scene information.

In step 403, imaging quality information of the third image is acquired.

The determining the first film forming rate according to the imaging quality information of the first image comprises the following steps: step 404, determining a first film forming rate according to the imaging quality information of the first image and the imaging quality information of the third image.

In one embodiment, the photographing apparatus that performs the photographing operation in the third photographing scene is the same apparatus as the photographing apparatus that performs the photographing operation in the first photographing scene. For example, when the first film rate is the film rate of the photographing apparatus, the two photographing apparatuses are the same apparatus.

In another embodiment, the photographing apparatus that performs the photographing operation in the third photographing scene is a different apparatus from the photographing apparatus that performs the photographing operation in the first photographing scene. For example, when the first film rate is the film rate of a certain shooting mode, the two shooting devices may be the same device or different devices.

Illustratively, the first scene information and the third scene information may be any two of the above-described scene information 1 to 4, and the first film rate may be a film rate of the photographing apparatus.

Illustratively, the first scene information and the third scene information may be any two of the above-described scene information 5 to 8, and the first clip rate may be a clip rate of vendor 1.

Illustratively, the first scene information and the third scene information may be any two of the above-described scene information 9 to 12, and the first clip rate may be a clip rate of vendor 2.

Illustratively, the first scene information and the third scene information may be any two of the above-described scene information 5, 7, 9, 11, and the first clip rate may be a clip rate corresponding to the high frequency dither pattern.

In the case of presetting a plurality of scene information, in one implementation manner, corresponding shooting scenes can be configured for each scene information in turn. After the photographing scene is configured, photographing operation can be performed in the photographing scene. After the photographing operation under the current photographing scene is completed, the next photographing scene can be configured.

For example, 3 pieces of scene information, namely scene information 1, scene information 2 and scene information 3, are preset. The image is shot firstly for scene information 1, then for scene information 2, and finally for scene information 3.

For example, after the photographing operation is completed in the photographing scene corresponding to the scene information 2, it may be determined that the scene information 2 is not the last scene information, so that the next scene information of the scene information 2, that is, the scene information 3, may be taken, and the scene information 3 is taken as the first scene information, step 201 is executed again, so as to configure the photographing scene corresponding to the scene information 3, and the photographing operation is executed in the photographing scene.

In the case of presetting a plurality of scene information, in another implementation manner, one of the preset scene information may be randomly taken to capture an image until each of the preset scene information is used to capture the image. This embodiment is not limited thereto.

The embodiment determines the film forming rate under the condition of covering the whole scene, and can improve the accuracy and persuasion of evaluating the film forming rate.

In the case where the photographing apparatuses of different zoom magnifications and different apparatus types need to be switched, considering that the switching of the different zoom magnifications and the switching of the photographing apparatuses of different apparatus types may cause a change in the photographing framing composition, an operation for realizing the standardized composition may be performed so that the image compositions photographed by the photographing apparatuses of different apparatus types under different zoom magnifications remain consistent, and all have the standardized composition effect.

Based on the standardized composition effect, the contrast analysis among the images obtained by shooting in different shooting scenes can be facilitated, the adverse effect of composition inconsistency among the images obtained by shooting in different shooting scenes on the film rate determination is eliminated, and the accurate determination of the film rate is facilitated.

Thus, in one embodiment, the configuration items include: configuration information of at least one of a zoom magnification of the photographing apparatus and an apparatus type of the photographing apparatus; the configuring the first photographing scene includes: executing a first operation, wherein the first image comprises an image of the image card, and the relative position relationship between the image of the image card and the first image is the same as a preset first relative position relationship; the image card is located in the image acquisition range of the shooting equipment.

In the standardized composition effect, the preset first relative positional relationship may be: the position of the second image in the first image is fixed, the ratio of the second image to the first image is fixed, etc.

As shown in fig. 5, one embodiment of the present application provides another method for determining a film rate. Referring to fig. 5, the method may include the following steps 501 to 507.

Step 501, configuring a corresponding photographing scene according to preset scene information, wherein the scene information comprises illumination environment information, shake mode information, zoom ratio information and smart phone information.

Before configuring the first photographing scene, the user may erect the graphics card in advance, so that the graphics card is located in the image acquisition range of the smart phone, that is, the image shot by the smart phone includes the image of the graphics card, erect the smart phone on the mobile phone installation position of the shake simulation control system, connect the smart phone with the personal computer, and then open the personal computer and the smart phone.

The information of the installed smart phone is consistent with the information of the smart phone in the current scene information. When scene information is replaced to replace a photographing scene, the installed smart phone is replaced correspondingly.

The various steps in the embodiment shown in fig. 5 may be performed by the personal computer.

Because the embodiment of the application relates to the change of the zoom magnification and the smart phone, in the process of configuring the current photographing scene, standardized composition can be carried out according to the zoom magnification information and the smart phone information in the current scene information.

Because the embodiment of the application relates to the change of the illumination environment and the dithering mode, in the process of configuring the current photographing scene, the light control system can be controlled to configure the corresponding illumination environment and the dithering simulation control system can be controlled to configure the corresponding dithering mode according to the illumination environment information and the dithering mode information in the current scene information.

After the personal computer is configured with the photographing scene, the smart phone can be triggered to execute photographing operation to start image acquisition.

In one embodiment, the personal computer may control the smart phone to end the shooting operation in the current shooting scene when determining that the smart phone shoots a preset number of images. In another embodiment, the smartphone may end the photographing operation when it determines that a preset number of images have been photographed.

Step 502, obtaining an image corresponding to scene information, which is shot by a smart phone corresponding to the scene information in a shooting scene.

In the embodiment shown in fig. 5, after each photographing scene is configured, the personal computer may acquire each image photographed by the corresponding smart phone under the photographing scene.

In other embodiments, the personal computer may also obtain, after each photographing scene is configured, each image photographed by each smart phone under the corresponding photographing scene (or under each photographing scene by the same smart phone).

Step 503, determining whether the image capturing under the shooting scene corresponding to each preset scene information is completed, if yes, executing step 505, otherwise executing step 504.

Step 504, another preset scene information is acquired, and step 501 is executed again according to the acquired scene information.

In one implementation, the preset scene information may be sequentially arranged, and a corresponding shooting scene may be sequentially configured for each scene information from first to second. Thus, step 503 may determine whether the current scene information is the last scene information, if so, the image capturing in all the photographing scenes is completed, and if not, the image capturing in all the photographing scenes is not completed yet. The other scene information in step 504 may be the next scene information to the current scene information.

The images shot by the smart phone can be automatically led out to the personal computer.

And 505, classifying and storing the acquired images according to the intelligent mobile phone information in the scene information corresponding to the images.

Images corresponding to the same smart phone information can be classified into a category, and the naming of the category of images can be the smart phone information. Based on the images, the film rate corresponding to the smart phone information can be determined.

In one implementation, the smart phone may automatically record a corresponding exposure time when capturing an image, and the exposure time and the captured image may be classified and stored together.

The exposure times of different smartphones may be correspondingly different. The exposure time can be used as auxiliary information for evaluating the film forming rate, so that the understanding and judgment of the film forming rate by a user are enhanced.

For example, when comparing the film forming rate of the smart phone 1 and the film forming rate of the smart phone 2, the user can know the exposure time of the smart phone 1 and the exposure time of the smart phone 2, and if the exposure time is consistent, the comparison of the film forming rates of the two can be considered to be more accurate (different from the inconsistent exposure time, the influence of the factor of the exposure time on the film forming rate can be eliminated when the exposure time is consistent).

Step 506, calculating the sharpness of the stored image using a contour extraction method based on gradient operators.

For example, the image sharpness may be calculated using a contour extraction method based on Sobel gradient operators.

In other embodiments of the present application, other algorithms may be used to calculate image sharpness.
