For example, for a specific description of the click input and the slide input, reference may be made to the description of the click input and the slide input in the description of the first input in step 204a, which is not repeated herein.
In another possible case, the electronic device saves the second target image in a case where the shake degree of the electronic device is within the second target range.
Exemplarily, the following may be preset (electronic device default setting, user setting according to own requirement): and when the shaking degree of the electronic equipment is in the fourth range, the sixth image is stored, when the shaking degree of the electronic equipment is in the fifth range, the seventh image is stored, and when the shaking degree of the electronic equipment is in the sixth range, the eighth image is stored. At least two of the fourth range, the fifth range and the sixth range may be the same or different, and may or may not have an overlapping area, which may be specifically determined according to actual use requirements, and the embodiment of the present application is not limited. The fourth range may be the same as or different from the first range; the fifth range and the second range may be the same or different; the sixth range and the third range may be the same or different; the embodiments of the present application are not limited. If the second target range is the fourth range, the electronic equipment stores a sixth image, and if the second target range is the fifth range, the electronic equipment stores a seventh image; and if the second target range is the sixth range, the electronic equipment saves the eighth image.
Illustratively, the eighth image may be saved when the degree of shake of the electronic device is low, and at least one of the sixth image and the seventh image may be saved when the degree of shake of the electronic device is high.
In the embodiment of the application, various conditions for storing the second target image are designed, so that the anti-shake image meeting the user requirements can be better provided for the user.
Exemplarily, first, the user triggers the electronic device to start the camera APP, and starts the anti-shake function mode, at which time the electronic device may default to open a plurality of cameras (at least two cameras, for example, a rear wide-angle camera (the field angle is generally larger than the main camera) and a rear main camera). The mutual position relations of the cameras on the bottom layer of the camera are known (the position relations refer to internal references and external references of the cameras when the cameras are calibrated). Secondly, the user triggers the electronic device to capture two first images through the two cameras by inputting (as shown in fig. 2), and then performs image registration processing, image fusion processing, image stitching processing (a second image, as shown in fig. 3), and electronic anti-shake processing (a third image) on the two first images. Thereby obtaining an anti-shake picture which is clearer than the image obtained by shooting in the anti-shake function mode by using a single camera at present or has a larger field angle. Meanwhile, the electronic equipment can display two small windows on a shooting preview interface, wherein one small window is an eighth image shot by a single camera in an anti-shake function mode, and the other small window is a third image shot by two cameras in a multi-shooting anti-shake function mode. The user can select the required image according to the self requirement.
It can be understood that the anti-shake images captured by the rear main camera and the rear wide-angle camera can achieve a larger field angle (the field angle of the wide-angle camera is larger than that of the main camera within the same capturing distance) and better anti-shake image quality (because the image details are increased by the overlapping portion of the image captured by the main camera and the image captured by the wide-angle camera) than the anti-shake image captured by the rear main camera alone, compared with the anti-shake image captured by only the rear main camera, due to the fusion of the image contents captured by the rear wide-angle camera. The anti-shake image obtained by shooting through the rear main camera and the rear wide-angle camera is compared with the anti-shake image obtained by shooting through the rear wide-angle camera, and due to the fact that the image content shot through the rear main camera is fused, the field angle larger than that of single wide-angle anti-shake and better anti-shake image quality can be achieved (because the image details are increased at the overlapping part of the image shot by the main camera and the image shot by the wide-angle camera, the main shooting can well supplement the image quality details shot at the wide angle within the same shooting distance, which are inferior to that of the main shooting, meanwhile, the image quality required to be lost for electronic anti-shake processing can be reduced through superposition of the two images, and therefore (compared with single wide-angle anti-shake) the field angle can be improved).
For example, since images captured by a plurality of cameras may be combined into a 3d image, and an electronic anti-shake process is performed on the 3d image (an electronic anti-shake process is performed on a 2d image, and an electronic anti-shake process is performed on a depth image (which may also be referred to as a depth anti-shake process) to obtain an anti-shake stereoscopic picture, in this embodiment, a stereoscopic anti-shake process may also be performed on the 3d image), a stereoscopic anti-shake picture (a seventh image) may be obtained. The stereoscopic anti-shake picture can have two display modes: mode 1, directly displaying a 3d dummy picture; in the mode 2, a movie screen with polarized light is displayed in cooperation with 3d glasses.
Optionally, when the screen of the electronic device outputs the left-eye image, the left lens is in a transparent state, and the right eye is in a non-transparent state, and when the screen of the electronic device outputs the right-eye image, the right lens is in a transparent state, and the left eye is in a non-transparent state, so that the user can see the images of different polarized lights displayed by the electronic device through the 3d glasses, and the purpose of viewing the 3d depth anti-shake image is achieved.
It can be understood that when the anti-shake of the rear main camera is used, the depth anti-shake picture can be obtained through the auxiliary operation of the fusion of the image contents of the picture in the rear wide-angle camera, namely, the distance from the whole content of the picture to the photographer can be seen on the basis of common anti-shake, so that the 3d three-dimensional anti-shake experience is provided for the user.
