The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard RGB, YUV, or the like format.

Illustratively, the digital signal processor is configured to process digital signals, and may process other digital signals in addition to digital image signals. For example, when the electronic device 100 selects a frequency bin, the digital signal processor is used to fourier transform the frequency bin energy, or the like.

Illustratively, video codecs are used to compress or decompress digital video. The electronic device 100 may support one or more video codecs. In this way, the electronic device 100 may play or record video in a variety of encoding formats, such as: dynamic picture experts group (moving picture experts group, MPEG) 1, MPEG2, MPEG3, and MPEG4.

Illustratively, the gyroscopic sensor 180B may be used to determine a motion pose of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., x-axis, y-axis, and z-axis) may be determined by gyro sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects the shake angle of the electronic device 100, calculates the distance to be compensated by the lens module according to the angle, and makes the lens counteract the shake of the electronic device 100 through the reverse motion, so as to realize anti-shake. The gyro sensor 180B can also be used for scenes such as navigation and motion sensing games.

For example, the acceleration sensor 180E may detect the magnitude of acceleration of the electronic device 100 in various directions (typically, x-axis, y-axis, and z-axis). The magnitude and direction of gravity may be detected when the electronic device 100 is stationary. The acceleration sensor 180E may also be used to recognize the gesture of the electronic device 100 as an input parameter for applications such as landscape switching and pedometer.

Illustratively, a distance sensor 180F is used to measure distance. The electronic device 100 may measure the distance by infrared or laser. In some embodiments, for example, in a shooting scene, the electronic device 100 may range using the distance sensor 180F to achieve fast focus.

Illustratively, ambient light sensor 180L is used to sense ambient light level. The electronic device 100 may adaptively adjust the brightness of the display 194 based on the perceived ambient light level. The ambient light sensor 180L may also be used to automatically adjust white balance when taking a photograph. Ambient light sensor 180L may also cooperate with proximity light sensor 180G to detect whether electronic device 100 is in a pocket to prevent false touches.

Illustratively, the fingerprint sensor 180H is used to capture a fingerprint. The electronic device 100 may utilize the collected fingerprint feature to perform functions such as unlocking, accessing an application lock, taking a photograph, and receiving an incoming call.

Illustratively, the touch sensor 180K, also referred to as a touch device. The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a touch screen. The touch sensor 180K is for detecting a touch operation acting thereon or thereabout. The touch sensor 180K may communicate the detected touch operation to the application processor to determine the touch event type. Visual output related to touch operations may be provided through the display 194. In other embodiments, the touch sensor 180K may also be disposed on the surface of the electronic device 100 and at a different location than the display 194.

Currently, after the electronic device detects that the user pops up the shooting control, the electronic device is triggered to generate a real thumbnail image and a shooting image (for example, a shooting true image); the electronic equipment cannot display the thumbnail image at the moment of detecting the pop-up shooting control, namely the electronic equipment detects that the duration between the pop-up shooting control and the thumbnail image is too long; the shooting waiting time of the user is longer, so that the shooting experience of the user is poorer.

In view of the above, embodiments of the present application provide a method of displaying a thumbnail image and an electronic apparatus; in the embodiment of the application, shooting operation is divided into operation of clicking a shooting control and operation of bouncing the shooting control, and when the electronic equipment detects the operation of clicking the shooting control, the electronic equipment is triggered to store false thumbnail images in an album application program and generate real thumbnail images; the false thumbnail image is a thumbnail image obtained by scaling based on the preview image; the real thumbnail image is a thumbnail image generated by selecting original image data for image processing; triggering and displaying a false thumbnail image when the electronic equipment detects that a user pops up a shooting control; the thumbnail image can be displayed at the moment when the electronic equipment detects the operation of bouncing the shooting control, so that the shooting response speed is improved; the shooting waiting time of the user is reduced, and shooting experience is improved.

In addition, triggering to generate a shooting image when the shooting control is detected to be sprung; after the real thumbnail image is generated, the false thumbnail image can be replaced by the real thumbnail image; after the shot image is generated, the real thumbnail image can be subjected to replacement processing through the thumbnail image obtained by scaling the shot image; the image quality of the thumbnail image can be ensured while improving the photographing response speed.

Fig. 2 is a schematic diagram of an application scenario of a method for displaying thumbnail images according to an embodiment of the present application.

Illustratively, after the electronic device runs the camera application, a preview interface 201 is displayed, as shown in fig. 2 (a); the preview interface 201 comprises a preview image, a thumbnail display control 202 and a shooting control 203, wherein the thumbnail display control 203 is used for displaying a thumbnail image of the last shot image; at a first time, the electronic device detects an operation of clicking the photographing control 203, as shown in (b) in fig. 2; at a second moment, the electronic device detects that the user has sprung up the shooting control 203, and displays a display interface 204, as shown in (c) in fig. 2; the thumbnail image displayed in the thumbnail display control 202 in the display interface 204 is still the thumbnail image of the last shot image; at the third time, the electronic device displays the display interface 205, and the thumbnail image displayed in the thumbnail display control 203 in the display interface 205 is the thumbnail image of the current captured image, as shown in (d) in fig. 2.

It should be understood that, in general, the user views the thumbnail image of the current shooting image as completing the current shooting, so that the electronic device cannot display the thumbnail image at the moment when the pop-up shooting control is detected, which results in that the user considers that the response of the shooting is too slow and the shooting experience is poor.

In an embodiment of the application, a method and an electronic device for displaying thumbnail images are provided; according to the method for displaying the thumbnail images, the problem that the shooting response time of the electronic equipment is long can be solved, and the electronic equipment can display the thumbnail images rapidly.

Alternatively, the method for displaying thumbnail images in the embodiment of the present application may be applied to a photographing mode of a camera application; or the method for displaying the thumbnail in the embodiment of the application can be applied to a quick photographing mode of a camera application program.

It should be noted that, the method for displaying thumbnail images in the embodiment of the present application may be applied to night scene shooting in a shooting mode, but is not applicable to a night scene shooting mode; because each frame of image acquired by the electronic equipment is obtained by fusing a long exposure image, a normal exposure image and a short exposure image in a night scene shooting mode; because in the embodiment of the application, the electronic equipment is triggered to generate the false thumbnail image and the real thumbnail image when the shooting control is detected to be clicked, and the false thumbnail image is displayed when the shooting control is detected to be sprung; after the false thumbnail image is displayed in the electronic equipment, the user considers that the electronic equipment can be moved when the shooting is completed; but at this time the short exposure image and the long exposure image may not have been generated yet; after the electronic equipment is moved, the contents in the short exposure image, the long exposure image and the normal exposure image are different, so that the image quality is poor; therefore, the method of displaying thumbnail images provided in the embodiment of the present application is not suitable for the night scene mode.

It should be understood that the foregoing is illustrative of an application scenario, and is not intended to limit the application scenario of the present application in any way.

The method of displaying thumbnail images provided in the embodiment of the present application will be described in detail with reference to fig. 3 to 16.

For example, when the electronic device is in a locked state, the user may instruct the electronic device to run the camera application through a gesture that slides to the right on the display screen of the electronic device. Or the electronic equipment is in a screen locking state, the screen locking interface comprises an icon of the camera application program, and the user instructs the electronic equipment to operate the camera application program by clicking the icon of the camera application program. Or when the electronic equipment runs other applications, the applications have the authority of calling the camera application program; the user may instruct the electronic device to run the camera application by clicking on the corresponding control. For example, while the electronic device is running an instant messaging type application, the user may instruct the electronic device to run the camera application, etc., by selecting a control for the camera function.

It should be appreciated that the above is illustrative of the operation of running a camera application; the camera application program can be run by the voice indication operation or other operation indication electronic equipment; the present application is not limited in any way.

It should also be understood that running the camera application may refer to launching the camera application.

S320, detecting a first operation of the first control.

Wherein the first operation is for instructing to start shooting. The photographing may include photographing.

Alternatively, the photographing operation may be a photographing operation.

Illustratively, as shown in (c) of fig. 6, the first operation may be a click operation on control 612.

Alternatively, in the embodiment of the present application, the above description is given by way of example of the first operation being a click operation; in the embodiment of the present application, the first operation may also be an operation of instructing shooting by voice; or instruct to start shooting operation by other instructions; the present application is not limited in any way.

S330, in response to the first operation, saving the first thumbnail image in the album application and generating a second thumbnail image.

The first thumbnail image is generated by the first image through first image processing; the second thumbnail image is a thumbnail image generated by the first image through a second image process, the first image process being different from the second image process.

Illustratively, the first thumbnail image may be a thumbnail image as displayed in the control 613 in (a) of fig. 7; the second thumbnail image may be a thumbnail image as displayed in the control 613 in (c) in fig. 7.

In one possible implementation, generating the first thumbnail image includes:

And scaling the first preview image to generate a first thumbnail image. The specific implementation may be referred to in the following description of the first flow 430 in fig. 4, which is not repeated here.

Optionally, the method further comprises:

For example, algorithms for the Raw color space may include, but are not limited to: black level correction processing (Black Level Correction, BLC), lens shading correction (LENS SHADING correction, LSC), and the like.

The black level correction processing is used for correcting the black level, wherein the black level refers to the level of a video signal which is not output by a row of brightness on a display device after a certain calibration; the reason for performing the black level correction is that: on one hand, the dark current exists in the image sensor, so that the pixel also has the problem of voltage output under the condition of no illumination; on the other hand, the accuracy is insufficient when the image sensor performs analog-to-digital conversion. Lens shading Correction (LENS SHADING Correction, LSC) is used to eliminate the problem of color around the image and the inconsistency of brightness with the center of the image due to the lens optics.

For example, the second algorithm includes an algorithm that converts the Raw image into a YUV color space.

Optionally, the method further comprises:

Acquiring time information of detecting a first operation; a first image is selected in a zero second delay queue in the electronic device based on time information.

In the embodiment of the application, when the electronic equipment detects the operation of bouncing the shooting control, the electronic equipment is triggered to generate a first image, wherein the first image can be a shooting image, namely a shooting true image; by performing the scaling process on the first image, a third thumbnail image, that is, a thumbnail image of the captured image can be obtained.

Optionally, generating the first image includes:

performing first algorithm processing on the second image to obtain an image in a first color space; fusing at least two frames of images in the first color space to obtain a fused image; and performing second algorithm processing on the fusion image to generate a first image.

Optionally, the method further comprises:

generating a third image of the first photographic subject in response to the second operation; and replacing the second thumbnail image of the first storage area by a third image, wherein the image quality of the third image is better than that of the second thumbnail image.

Alternatively, the image frames stored in the ZSL queue may be Raw images; the Raw image refers to Raw image data acquired by the image sensor.

S442, processing the selected image frames to generate a real thumbnail image.

Illustratively, the selected Raw image may be processed to convert the Raw image to a YUV image; the YUV image can be converted into RGB image for display; in addition, the YUV image may be converted into other formats (e.g., JPEG format (JPG format), GIF format, DNG format, or RAW format, etc.) for storage.

It should be understood that since the real thumbnail image is a thumbnail image obtained by performing image processing based on the Raw image; the false thumbnail image is a thumbnail image obtained by directly scaling the preview image stored in the electronic equipment; therefore, the timeliness of generating the false thumbnail image is higher than that of generating the real thumbnail image.

Alternatively, the electronic device may generate the quick thumbnail image first and then generate the real thumbnail image.

It should also be understood that since the real thumbnail image is a thumbnail image obtained by performing image processing based on the Raw image; the false thumbnail image is a thumbnail image obtained by directly scaling the preview image; since preview images are typically lower in resolution than Raw images captured by the image sensor, the image quality of real thumbnail images is better than that of false thumbnail images.

In an embodiment of the present application, after a real thumbnail image is generated, a false thumbnail image stored in an electronic device is directly replaced by the real thumbnail image; compared with the storage of the false thumbnail image and the real thumbnail image, the method and the device directly perform replacement processing in the embodiment of the application, so that the storage space of the electronic equipment occupied by the thumbnail image can be reduced.

Alternatively, the image frames used to generate the captured image may be obtained directly from the second process 440.

S472, generating a shooting image based on the selected image frame.

Illustratively, the selected Raw image may be processed to convert the Raw image to a YUV image; the YUV image can be converted into RGB image for display; in addition, the YUV image may be converted to other formats (e.g., JPEG format, JPG format, GIF format, etc.) for storage.

It should be appreciated that the captured image differs from the actual thumbnail image in that the resolution and image quality of the captured image are typically better than the actual thumbnail image.

Optionally, S472 includes, but is not limited to, the following steps:

1. Carrying out a Raw domain algorithm on the selected Raw image to obtain a processed Raw image; wherein the Raw domain algorithm includes, but is not limited to: black level correction processing, lens shading correction and other algorithms;

2. carrying out fusion processing on the multi-frame processed Raw image to obtain a fused Raw image;

Alternatively, the thumbnail image of the captured image may refer to a thumbnail image obtained by performing a scaling process on the captured image after the captured image is generated.

It should be understood that, assuming that the image size of the dummy thumbnail image is a first size, the image size of the real thumbnail image is a second size, and the image size of the photographed image is a third size; wherein the first size is the same as the second size; the third dimension is greater than the first dimension, or the third dimension is greater than the second dimension.

It should be understood that capturing an image may refer to capturing a true image generated by the image at a time; compared with a real thumbnail image, the shot image does not need to be subjected to downsampling processing; in addition, the photographed image may be an image based on a multi-frame Raw image fusion process; therefore, the image quality of the photographed image is better than that of the real thumbnail image.

After the electronic device generates the shot image, a thumbnail image obtained by scaling the shot image may be displayed on a display interface of the camera application, as shown in fig. 8 (a); at this time, stored in the album application is a captured image, such as image 111 shown in (b) in fig. 8.

For example, as can be seen from (a) in fig. 10 and (b) in fig. 10, the thumbnail image displayed in the thumbnail control 812 in the preview interface 810 is a thumbnail image corresponding to the first captured image 821; if the electronic device detects an operation to click on the thumbnail control 812, it may index into the first captured image 821 in the album application and display the first captured image 821.

It should be appreciated that the cache module 830 is not shown in the display interface 820 of the camera application; the buffer module 830 is a module for storing images in the electronic device.

Illustratively, at time T (21), the electronic device detects an operation to click on the capture control 812; for example, the operation of clicking the photographing control 812 for the first time is detected, as shown in (c) in fig. 10; at this time, the thumbnail image displayed in the thumbnail display control 813 is a thumbnail image of the last completed captured image (for example, a thumbnail image of the first captured image 821); when the electronic device detects an operation of clicking the photographing control 812 by the user, the display interface of the album application is as shown in (d) of fig. 10; at time T (22), the electronic device detects operation of bouncing the capture control 812, and displays a display interface 814; for example, detecting the operation of bouncing the shooting control 812 for the first time, the display interface 814 is displayed; the display interface 814 includes the second shot 815 and a thumbnail display control 813, where the thumbnail image displayed in the thumbnail display control 813 is a false thumbnail image of the first shot 811, as shown in (a) in fig. 11; at this time, as shown in (b) in fig. 11, the false thumbnail image 1 of the first photographic subject and the first photographic image 821 are included in the display interface 823 of the album application; the buffer module 830 includes a false thumbnail image of the first photographing object and the first photographing image; at time T (23), after the electronic device generates a real thumbnail image of the first photographic subject, display interface 816 is displayed; the display interface 816 includes a second shot 815, a thumbnail display 813, and a shot 812, and a thumbnail display 8613 displays a real thumbnail image of the first shot, as shown in fig. 11 (c); at this time, as shown in (d) of fig. 11, the camera application display interface 824 includes the real thumbnail image 11 of the first photographic subject and the first photographic image 821; the buffer module 830 stores therein the real thumbnail image of the first photographing object and the first photographing image.

After the real thumbnail image of the first photographic subject is generated in the electronic device, the real thumbnail image of the first photographic subject is displayed in the display interface, and the dummy thumbnail image 1 of the first photographic subject is subjected to substitution processing by the real thumbnail image 11 of the first photographic subject in the album application.

Illustratively, at time T (24), the electronic device detects an operation to click on the capture control 812, displaying a display interface 816; for example, the operation of clicking the photographing control 812 for the second time is detected, as shown in (a) in fig. 12; the display interface 816 includes a second shot 815 and a thumbnail display control 813, and the thumbnail display control 813 displays a real thumbnail image of the first shot 811; at this time, as shown in (b) in fig. 12, the real thumbnail image 11 of the first photographic subject and the first photographic image 821 are included in the display interface 824 of the album application; the buffer module 830 includes a real thumbnail image of the first photographing object and the first photographing image. At time T (25), the electronic device detects an operation of bouncing the shooting control 812, and displays a display interface 817; for example, the operation of bouncing the shooting control 812 for the second time is detected, and the display interface 817 is displayed; the display interface 817 includes a third shooting object and a thumbnail display control 813, where the thumbnail image displayed in the thumbnail display control 813 is a false thumbnail image of the second shooting object 815, as shown in (c) in fig. 12; at this time, as shown in (d) of fig. 12, the false thumbnail image 2 of the second photographic subject, the true thumbnail image 11 of the first photographic subject, and the first photographic image 821 are included in the display interface 825 of the booklet application; the buffer module 830 includes a false thumbnail image of the second photographing object, a real thumbnail image of the first photographing object, and the first photographing image.

Alternatively, after the photographed image of the first photographing object is generated in the electronic device, a replacement process is performed on the real thumbnail image of the first photographing object through the photographed image of the first photographing object in the album application.

It should be appreciated that since the second shot is operated later than the first shot; therefore, even if the electronic device generates the photographed image of the first photographing object after the electronic device displays the thumbnail image of the second photographing object, the thumbnail image of the photographed image of the first photographing object is not displayed in the thumbnail display control in the display interface in the camera application; therefore, the display interface of the camera application is the same at time T (26) as at time T (25).

It should also be appreciated that the second shot is a two-shot independent shooting process from the first shot; therefore, in the cache module in the camera application program, the previously generated thumbnail image is replaced by the later generated real thumbnail image in the same shooting process; replacing the previously generated real thumbnail image with the later generated photographed image; but the second shot image does not replace the first shot image.

Illustratively, at time T (27), the electronic device generates a real thumbnail image of the second photographic subject, and displays a display interface 818, as shown in (c) in fig. 13; the display interface 818 includes a third shooting object and a thumbnail display control 813, where the thumbnail display control 813 displays a real thumbnail image of the second shooting object; at this time, as shown in (d) of fig. 13, the real thumbnail image 22 of the second photographic subject, the photographic image 111 of the first photographic subject, and the first photographic image 821 are included in the display interface 827 of the album application; the buffer module 830 stores the real thumbnail image of the second subject, the captured image of the first subject, and the first captured image.
