Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
In the related art, a layer of filtering film is coated on a lens of a camera, and infrared laser emitted by a TOF (Time of flight) module is filtered through the filtering film. However, the method has the problem that the cost of the filtering film is high, under the limit of a certain cost, the cut-off performance of the filtering film is difficult to just remove the infrared laser, and other light can be influenced, namely, the filtering film can remove the infrared light and the light of other wave bands at the same time, so that the light input amount is reduced, the photographed image is darkened, and the photographing experience of a user is poor.
In addition, in order to improve photographing quality, the existing electronic devices (such as mobile phones) use multi-frame synthesis technology when photographing. When previewing, the photographed picture is stored in real time, and when the shutter key is pressed, the current photographed picture and 8-10 photographed pictures stored before are taken for multi-frame synthesis so as to ensure photographing quality.
In the method, if the influence of infrared laser is to be removed, when the shutter is to be pressed down, firstly infrared light is removed, then the shutter is pressed down again after 8-10 frames of photographing pictures are determined, and then the current photographing picture and 8-10 previous stored photographing pictures are taken for multi-frame synthesis. However, this increases the photographing time, and the waiting time of the user is long, and the experience is poor.
Moreover, the method is only suitable for photographing (taking pictures), is not suitable for video and previewing scenes, and has a narrow application range and poor adaptability.
Aiming at the problem of purple specks caused by a TOF module in the related art, the disclosure provides an image shooting method which is applied to electronic equipment. According to the image shooting method, when an image is shot, whether the laser ranging module (e.g. the TOF module) is closed or not is determined according to the laser ranging information, the focusing distance information and the environment light information, so that the problem of purple spots generated by shooting in a special environment is solved, the shooting effect can be ensured, and the shooting experience of a user is improved.
In one exemplary embodiment, there is provided an image photographing method, as shown with reference to fig. 1, including:
s110, acquiring laser ranging information, focusing distance information and ambient light information.
The laser ranging information refers to a distance value measured using a laser. For the electronic equipment provided with the TOF module, the TOF module can directly determine the laser ranging information, and the TOF module reports the laser ranging information to the controller after determining the laser ranging information. When facing glass materials, laser is reflected, so that the back transmission time of the laser sent by the TOF module is shorter, and the determined laser ranging information is smaller. For example, when the electronic apparatus photographs a photographic target outside the glazing against the glazing, if the distance between the camera and the glazing is 10 cm and the distance between the camera and the photographic target outside the glazing is 100 m, the obtained laser ranging information is 10 cm.
The focusing distance information refers to the distance information determined by the focusing module, and the focusing module reports the focusing distance information to the controller after determining the focusing distance information. When the electronic device shoots a shooting target outside the glass window opposite to the glass window, the determination of the focusing distance information is not influenced by the glass window, and if the distance between the camera and the shooting target is 100 meters and the distance between the camera and the glass window is 10 centimeters, the determined focusing distance information is 100 meters.
The ambient light information refers to the illumination intensity, also called illuminance, of the light of the shooting environment, and can be sensed by light sensing and then reported to the controller. Ambient light information may be obtained by light sensor detection.
S120, setting a shooting mode to a preset mode according to the laser ranging information, the focusing distance information and the ambient light information, wherein the laser ranging module is in a closed state in the preset mode.
When the step is executed, judgment is needed according to the laser ranging information, the focusing distance information and the ambient light information, when certain conditions are met, the shooting mode is set to be a preset mode, and if the conditions are not met, shooting is carried out in other modes stored in the electronic equipment.
S130, image shooting is carried out in a preset mode.
When the judgment result in step S120 is that the shooting mode is the preset mode, the controller of the electronic device controls the laser ranging module to be in the off state, and performs image shooting when the laser ranging module is in the off state.
If the entering of the preset mode is determined according to the laser ranging information, the focusing distance information and the ambient light information, the fact that an object reflecting infrared light exists in the current shooting state is indicated, purple spots are prone to occurring on a shot picture, and in order to improve shooting effect, the laser ranging module can be closed for image shooting. That is, the laser ranging module is in the closed state for shooting, so that the influence of laser emitted by the laser ranging module (such as a TOF module) on shooting is eliminated, the generation of purple spots is avoided, the shooting effect is improved, and the user experience is improved.
Here, it should be noted that, in the embodiment, the obtaining manner of the laser ranging information may be obtained by starting the laser ranging module for detection, that is, before entering the preset mode, the laser ranging module is in the on state. The laser ranging information may be obtained by using information obtained before, that is, before entering the preset mode, the laser ranging module is in the off state.
In addition, it should be noted that if the laser ranging information, the focusing distance information and the ambient light information are judged and then do not meet the conditions, if the preset mode is not entered according to the laser ranging information, the focusing distance information and the ambient light information, it is stated that in the current shooting state, no object which can reflect infrared light exists, and purple spots are not easy to generate on the shot image, at this time, the laser ranging module (such as the TOF module) can be controlled to be in the on state for shooting, focusing and white balance are assisted through the laser ranging module, the shooting effect is improved, and the user experience is improved.
According to the image shooting method, when an image is shot, whether the laser ranging module (such as a TOF module) is closed or not is determined according to the laser ranging information, the focusing distance information and the environment light information, namely, the opening and closing of the laser ranging module are determined according to the actual conditions, so that the ultraviolet spots can be eliminated, the shooting effect can be ensured, and the use experience is improved.
In one exemplary embodiment, an image photographing method is provided, which is a further improvement of the above image photographing method. Illustratively, setting the photographing mode to the preset mode according to the laser ranging information, the focusing distance information, and the ambient light information may include: and setting a shooting mode as a preset mode under the condition that the laser ranging information meets the first preset condition, the focusing distance information meets the second preset condition and the ambient light information meets the third preset condition.
And judging whether the laser ranging information, the focusing distance information and the ambient light information meet the condition or not.
In a specific implementation process, setting the shooting mode to the preset mode according to the laser ranging information, the focusing distance information and the ambient light information may be performed in the following manner. Referring to fig. 2, determining whether to enter a preset mode according to laser ranging information, focusing distance information and ambient light information includes:
s210, judging whether the laser ranging information meets a first preset condition, the focusing distance information meets a second preset condition and the environment light information meets a third preset condition.
The method comprises the steps of judging whether the laser ranging information meets a first preset condition, judging whether the focusing distance information meets a second preset condition and judging whether the ambient light information meets a third preset condition, wherein the three steps can be performed simultaneously or sequentially.
When the three are performed simultaneously, the judging time can be shortened, and the latter judgment is performed after the former judgment is not needed to be completed.
When the three are performed in sequence, the sequence of the three can be set in advance, and the sequence of the three can be determined according to the sequence of the obtained laser ranging information, focusing distance information and ambient light information.
In one example, the advance setting is performed sequentially to determine whether the laser ranging information satisfies a first preset condition, to determine whether the focusing distance information satisfies a second preset condition, and to determine whether the ambient light information satisfies a third preset condition.
In this example, regardless of the order in which the laser ranging information, the focusing distance information, and the ambient light information are acquired, it is directly determined in a fixed order whether the laser ranging information satisfies a first preset condition, whether the focusing distance information satisfies a second preset condition, and whether the ambient light information satisfies a third preset condition, and then whether to enter a preset mode is determined according to the result.
In one example, determining whether the laser ranging information meets the first preset condition, whether the focusing distance information meets the second preset condition, and whether the ambient light information meets the third preset condition are determined according to the sequence of acquiring the laser ranging information, the focusing distance information and the ambient light information, so that shooting efficiency is improved.
For example, if the ambient light information is obtained first, whether the ambient light information meets a third preset condition is judged first; secondly, acquiring laser ranging information, and secondly judging whether the laser ranging information meets a first preset condition; and finally, judging whether the focusing distance information meets a second preset condition or not. And then determining whether to enter a preset mode according to the judging result.
S220, determining to enter a preset mode when the laser ranging information, the focusing distance information and the environment light information respectively meet a first preset condition, a second preset condition and a third preset condition.
Any one of the laser ranging information, the focusing distance information and the ambient light information does not meet the corresponding preset conditions, and is insufficient for generating the purple specks. Thus, it is set as follows: and determining to enter a preset mode when the laser ranging information, the focusing distance information and the ambient light information simultaneously meet corresponding preset conditions.
S230, when the laser ranging information, the focusing distance information and the ambient light information do not respectively meet the first preset condition, the second preset condition and the third preset condition, determining that the preset mode is not required to be entered.
The "laser ranging information, focusing distance information and ambient light information do not satisfy the first preset condition, the second preset condition and the third preset condition" means that at least one of the results of "judging whether the laser ranging information satisfies the first preset condition", "judging whether the focusing distance information satisfies the second preset condition" and "judging whether the ambient light information satisfies the third preset condition" is "no".
In one example, after all of the laser ranging information to be judged whether the first preset condition is satisfied, the focusing distance information is judged whether the second preset condition is satisfied, and the ambient light information is judged whether the third preset condition is satisfied, whether to enter a preset mode is determined according to the judgment result.
In this example, it is determined whether the laser ranging information satisfies a first preset condition, whether the focusing distance information satisfies a second preset condition, and whether the ambient light information satisfies a third preset condition, and then whether to enter a preset mode is determined according to the determination result.
Only when the laser ranging information, the focusing distance information and the environment light information respectively meet the first preset condition, the second preset condition and the third preset condition, the ultraviolet spot can be generated, the laser ranging module is determined to enter the preset mode at the moment, the laser ranging module is closed for image shooting, the ultraviolet spot is eliminated, and the shooting effect is improved.
In one example, the two components are directly in a fixed order: firstly judging whether the laser ranging information meets a first preset condition, secondly judging whether the focusing distance information meets a second preset condition, finally judging whether the ambient light information meets a third preset condition, and then determining whether to enter a preset mode according to the result.
In this example, after the three are judged, whether to enter a preset mode is determined according to the judgment result.
In one example, the two components are directly in a fixed order: firstly judging whether the laser ranging information meets a first preset condition, secondly judging whether the focusing distance information meets a second preset condition, finally judging whether the ambient light information meets a third preset condition, and then determining whether to enter a preset mode according to the result.
In this example, if the laser ranging information does not satisfy the first preset condition, no subsequent judgment is made, and it is directly determined that the preset mode is not required to be entered. If the laser ranging information meets the first preset condition, but the focusing distance information does not meet the second preset condition, the subsequent judgment is not carried out, and the fact that the user does not need to enter the preset mode is directly determined. That is, in this example, only when the determination result of the former is yes, the subsequent determination is performed, otherwise, it is directly determined that the preset mode is not required to be entered, so that the determination efficiency is improved, and further, the shooting efficiency is improved.
In one example, determining whether the laser ranging information meets the first preset condition, whether the focusing distance information meets the second preset condition, and whether the ambient light information meets the third preset condition are determined according to the sequence of acquiring the laser ranging information, the focusing distance information and the ambient light information, so that shooting efficiency is improved.
In this example, after the three are judged, whether to enter a preset mode is determined according to the judgment result.
In one example, determining whether the laser ranging information meets the first preset condition, whether the focusing distance information meets the second preset condition, and whether the ambient light information meets the third preset condition are determined according to the sequence of acquiring the laser ranging information, the focusing distance information and the ambient light information, so that shooting efficiency is improved.
In this example, for example, the ambient light information is obtained first, and then it is first determined whether the ambient light information satisfies a third preset condition; secondly, acquiring laser ranging information, and secondly judging whether the laser ranging information meets a first preset condition; and finally, judging whether the focusing distance information meets a second preset condition or not.
When the ambient light information does not satisfy the third preset condition, no operation is performed with respect to determining whether to enter the preset mode. For example, when it is determined that the ambient light information does not satisfy the third preset condition, if the laser ranging information is not acquired at this time, the operation of acquiring the laser ranging information is not performed any more, and it is directly determined that the entering of the preset mode is not required.
This example may further improve the efficiency of determining whether to enter the preset mode, thereby improving the photographing efficiency.
In an exemplary embodiment (this embodiment is not shown in the drawings), an image capturing method is provided, which is a further improvement of the above-described image capturing method. When the laser ranging information satisfies the first preset condition, the focusing distance information satisfies the second preset condition, and the ambient light information satisfies the third preset condition, before setting the photographing mode to the preset mode, the method may include: and determining that the focusing distance information meets a second preset condition when the focusing distance information is larger than or equal to a second preset distance.
Here, by determining whether the laser ranging information satisfies the first preset condition, determining that the laser ranging information satisfies the first preset condition based on the determination result, for example, by determining whether the laser ranging information is less than or equal to the first preset distance; if the laser ranging information is smaller than or equal to the first preset distance, the laser ranging information meets the first preset condition.
Since the conditions for generating the purple spots by different cameras are different, the first preset distance is determined according to the specific structure of the camera of the electronic device, and the first preset distance can be measured through experiments, for example.
In a first example, the first preset distance is 20cm. When the laser ranging information is 10cm, the laser ranging information is smaller than or equal to a first preset distance, and the laser ranging information meets a first preset condition; when the laser distance measurement information is 30cm, the laser distance measurement information is not smaller than or equal to the first preset distance, and the laser distance measurement information is not satisfied with the first preset condition.
When the laser ranging information meets the first preset condition, the focusing distance information meets the second preset condition, and the ambient light information meets the third preset condition, before the shooting mode is set to the preset mode, the method may further include: and determining that the focusing distance information meets a second preset condition when the focusing distance information is larger than or equal to a second preset distance.
Here, determining whether the focusing distance information satisfies the second preset condition may include the following: judging whether the focusing distance information is larger than or equal to a second preset distance; and if the focusing distance information is larger than or equal to the second preset distance, the focusing distance information meets the second preset condition.
Since the conditions for generating the purple spots by different cameras are different, the second preset distance is determined according to the specific structure of the camera of the electronic device, and the second preset distance can be measured through experiments, for example.
In one example, the second preset distance is 50cm. When the focusing distance information is 100m, the focusing distance information is larger than or equal to a second preset distance, and the focusing distance information meets a second preset condition; when the focusing distance information is 30cm, the focusing distance information is smaller than the second preset distance, and the focusing distance information does not meet the second preset condition.
In one example, the second preset distance is 50m. When the focusing distance information is 100m, the focusing distance information is larger than or equal to a second preset distance, and the focusing distance information meets a second preset condition; when the focusing distance information is 30m, the focusing distance information is smaller than the second preset distance, and the focusing distance information does not meet the second preset condition.
When the laser ranging information meets the first preset condition, the focusing distance information meets the second preset condition, and the ambient light information meets the third preset condition, before the shooting mode is set to the preset mode, the method may further include: and determining that the ambient light information meets a third preset condition when the ambient light information is smaller than or equal to the preset illumination value.
Here, determining whether the ambient light information satisfies the third preset condition may include the following manner: judging whether the ambient light information is smaller than or equal to a preset illumination value or not; if the ambient light information is less than or equal to the preset illumination value, the ambient light information meets a third preset condition.
Since conditions for generating the purple spots are different from one camera to another, the preset illuminance value is determined according to a specific structure of the camera of the electronic device, and may be measured by experiments, for example.
In one example, the preset illumination value is the illumination with the room on, for example 100Lux. When the ambient light information is 20Lux, the ambient light information is smaller than or equal to a preset illumination value, and the ambient light information meets a third preset condition; when the ambient light information is 200Lux, the ambient light information is not satisfied with the preset illumination value or less, and the ambient light information is not satisfied with the third preset condition.
In an exemplary embodiment, there is provided an image photographing method, which is a further improvement of the photographing method described above, for example, referring to fig. 3, after performing image photographing in a preset mode, the photographing method further includes:
S310, acquiring motion state information of the electronic equipment.
Wherein, the step of acquiring the motion state information of the electronic device includes acquiring the motion state information of the electronic device in real time and acquiring the motion state information of the electronic device at intervals.
The movement state information of the electronic equipment is acquired in real time, and then whether the laser ranging module is started or not is controlled according to the movement state information, so that the electronic equipment can be better ensured to quickly adjust the laser ranging module according to the movement state information, and the shooting effect is better improved.
The motion state information of the electronic equipment is acquired at intervals, so that the power consumption in the shooting process of the electronic equipment can be reduced better, the occupation of resources is reduced, and the shooting efficiency is improved.
