and step 108, displaying a third image obtained by image fusion of the first image and the at least one second image.
In the embodiment, the electronic device is provided with a flash lamp and a camera, and when the shooting environment brightness is low, the flash lamp is controlled to flash while the camera shoots so as to improve the brightness of the shot image.
The method comprises the steps of controlling a camera to shoot a first image of a shot scene, controlling the camera to carry out at least one position movement after the first image is shot, and shooting a second image after each position movement. Or after the first image is shot, controlling the flash lamp to carry out at least one position movement, and controlling the camera to shoot a second image after each position movement. And finally, carrying out image fusion on the first image and at least one second image to generate a third image, wherein the central area of the shot scene in the first image is a brighter image, and the edge area of the shot scene in the second image (namely the peripheral area of the central area of the shot scene) is a brighter image, so that the brightness of the center and the edge of the shot scene in the synthesized third image is brighter, and finally, displaying the third image. The embodiment of the application can shoot a photo with uniform brightness by adjusting the flash lamp or the camera, avoids the phenomena of brightness in the center of the photo and darkness around the center of the photo, improves the photographing imaging effect in the flash lamp mode, and meets the photographing requirement of a user.
For the electronic equipment with the camera having a larger camera view field range and a smaller flash lamp light spot range, when the electronic equipment shoots a picture, the brightness of the periphery of the picture is lower than that of the center of the picture. Therefore, by adopting the embodiment of the application, the camera has a larger shooting view field range and a smaller flash lamp light spot range, so that the brightness distribution of the center and the periphery of a picture shot by a flash lamp is more uniform.
It should be noted that the electronic device of the embodiment of the present application includes, but is not limited to, a mobile terminal, a tablet computer, a notebook computer, a wearable device, a vehicle-mounted terminal, and the like.
Further, in this embodiment of the present application, controlling a camera to capture a first image of a captured scene includes: and controlling the camera to shoot a first image under the condition that the central area of the lens field range of the camera and the central area of the facula range of the flash lamp are overlapped with the central area of the shot scene.
In this embodiment, the camera is controlled to capture the first image with the center region of the lens field range (i.e., the lens field angle) of the camera coinciding with the center region of the subject scene and the center region of the flare range of the flash coinciding with the center region of the subject scene. As shown in fig. 2, the flash 202 is disposed at a predetermined position of the electronic device 200 and is movable on the first region 206, and the camera 204 is disposed at a predetermined position of the electronic device 200 and is movable on the second region 208. The initial position of the flash 202 is such that the center of the flash 202 coincides with the center of the first region 206, and the initial position of the camera 204 is such that the lens center of the camera 204 coincides with the center of the second region 208.
Controlling the flash to be at an initial position, controlling the camera to be at an initial position, and when the flash is at the initial position and the camera is at the initial position, as shown in fig. 3, coinciding a central area of a shot scene 302, a central area of a lens field range 304 of the camera, and a central area of a light spot range 306 of the flash, and shooting a first image with the first image as a reference image.
Through the mode, an image with a brighter central area is shot, so that a reference is provided for acquiring a picture with uniform brightness.
Further, in this embodiment of the application, after controlling the camera to perform the position movement, controlling the camera to capture at least one second image of the captured scene includes: and controlling the camera to shoot a second image under the condition that the central area of the lens field range of the camera is overlapped with the edge area of the shot scene.
In this embodiment, the camera is controlled to make at least one movement after the first image is captured, and one second image is captured after each movement. The camera is moved but the flash lamp is not moved, so that the central area of the light spot range of the flash lamp coincides with the central area of the shot scene, and after the camera is moved, the central area of the lens view field range of the camera does not coincide with the central area of the light spot range of the flash lamp, but moves towards the edge of the light spot range of the flash lamp, namely the central area of the lens view field range is aligned with the edge area of the shot scene. Therefore, the purpose of increasing the brightness of the edge area of the shot scene in the second image is achieved by virtue of the characteristic that the transmittance of the central area of the lens field range is high.
Further, in this embodiment of the application, after controlling the flash to perform the position movement, controlling the camera to capture at least one second image of the shot scene includes: and controlling the camera to shoot a second image under the condition that the central area of the light spot range of the flash lamp is overlapped with the edge area of the shot scene.
In the embodiment, after the first image is shot, the flash lamp is controlled to move at least once, and the camera is controlled to shoot a second image after each movement. The central area of the lens view field range of the camera coincides with the central area of the shot scene because the flash lamp moves but the camera does not move, and after the flash lamp moves, the central area of the light spot range of the flash lamp does not coincide with the central area of the lens view field range of the camera but moves towards the edge of the lens view field range of the camera, namely the central area of the light spot range of the flash lamp is aligned with the edge area of the shot scene. In the above manner, the brightness of the edge area of the shot scene in the second image is improved.
For positional movement of the camera or flash, as shown in FIG. 2, the flash 202 may move in a first region 206 of the electronic device 200 and the camera 204 may move in a second region 208 of the electronic device 200. The movement here means that the flash 202 moves on the plane of the X-axis and Y-axis of the first region 206, where the X-axis is the lateral axis of the first region 206 and the Y-axis is the longitudinal axis of the first region 206. When the camera 204 is not moved and the flash 202 moves from the center position of the first region to the edge, the center region corresponding to the flash spot range moves from the center region to the edge region of the shot scene, so that the edge region of the shot scene is illuminated.
The camera 204 moves in an X-axis Y-axis plane of the second region 208, where the X-axis is a lateral axis of the second region 208 and the Y-axis is a longitudinal axis of the second region 208. When the flash 202 is still and the camera 204 moves from the center position of the second area to the edge, the center area corresponding to the lens field range moves from the center area to the edge area of the shot scene, so that the purpose of increasing the brightness of the edge area of the shot scene during shooting is achieved by virtue of the characteristic of high transmittance of the center area of the lens field range.
In the present embodiment, the direction of at least one movement is not limited, and for example, when the camera or the flash is controlled to move at a plurality of positions, the movement in any one of the left, right, up, and down directions may be performed.
Further, in this embodiment of the present application, displaying a third image obtained by image fusion of the first image and the at least one second image includes: determining a first coincident image in the first image which is coincident with the second image, and determining a second coincident image in the second image which is coincident with the first image; replacing the first superposed image in the first image with a second superposed image to generate a third image; and displaying the third image.
In this embodiment, a second composite image (i.e., an image with the same content as the first image) that is superposed with the first image is cut out from each second image, the second composite image cut out from each second image includes an image that tends to be in an edge area in the first image, and the brightness of this image in the second image is greater than the brightness of this image in the first image, further, the second composite image is replaced with a first composite image that is superposed with the second image in the first image, i.e., for the same image, an image with higher brightness is replaced with an image with lower brightness, and a final picture of the shot scene is generated, and each area of the shot scene in this picture is an image with higher brightness, so that the brightness of the whole picture is improved, and the brightness uniformity of the whole picture is improved.
Further, in this embodiment of the present application, the step of controlling the camera or the flash to perform at least one position movement includes: and controlling the adjusting device to enable the adjusting device to drive the camera or the flash lamp to move at least once.
In this embodiment, an adjusting device is installed on the electronic device, the adjusting device is connected with the camera or the flash lamp, the camera or the flash lamp is moved at least once by controlling the adjusting device, so that the overlapping area of the light spot of the flash lamp and the field range of the camera lens can be adjusted, and an image shot under different overlapping areas is synthesized to obtain a photo with uniform brightness distribution, so that the purpose of improving the shooting effect under the flash lamp mode is achieved.
In the embodiment of the application, adjusting device includes little cloud platform, adjusts the camera lens field of view scope of flash light facula or camera with the help of little cloud platform, and speed is very fast and can avoid the picture shake through suitable lock frame, improves the shooting effect, gives the better use of user and experiences.
The adjusting device can also comprise a driving unit and a motor, wherein the driving unit receives the control signal and drives the motor to rotate so as to drive the camera or the flash lamp to move.
Further, in this embodiment of the present application, before turning on the flash and controlling the camera to capture the first image of the captured scene in step 102, the capture control method further includes: detecting the brightness of the shooting environment; and entering a flash lamp shooting mode under the condition that the shooting environment brightness is smaller than a preset brightness threshold value.
In this embodiment, when it is determined that the brightness of the shooting environment is less than the preset brightness threshold, which indicates that the shooting environment is dark, the flash lamp needs to be controlled to flash while shooting, and the flash lamp flashes a picture with peripheral brightness significantly lower than the central brightness.
And when the brightness of the shooting environment is judged to be greater than or equal to the preset brightness threshold, the shooting environment is bright, a flash lamp does not need to be started during shooting, and only the camera is controlled to shoot.
By judging the brightness of the shooting environment, the function of flashing while shooting is controlled to be executed or not is controlled, the problem of overlarge exposure degree of an image caused by flash shooting under the condition of not flashing is avoided, and the flexibility of shooting control is improved.
