Description

Shooting method, storage medium, electronic device, and program product Technical Field The present invention relates to the field of image processing technologies, and in particular, to a shooting method, a storage medium, an electronic device, and a program product. Background Electronic devices such as cell phones are often configured with different cameras, such as wide angle cameras, main cameras, tele cameras, and the like. The focal lengths of different cameras in an electronic device are generally different, the magnifications (hereinafter referred to as "magnification") corresponding to the different focal lengths are different, and the field of view (FOV) corresponding to the different magnifications is different. For example, the longer the focal length, the larger the magnification and the smaller the angle of view. For example, the electronic device may take a low-magnification image at a large angle of view using a lower magnification or take a high-magnification image at a small angle of view using a higher magnification during the photographing process. However, when the electronic device photographs the same photographed scene with a lower magnification and a higher magnification, respectively, the display brightness of the obtained low-magnification image and high-magnification image may have a large difference. For example, in the same shooting scene, when the electronic device is shooting with a lower magnification, the display brightness of the high-magnification image is usually adjusted based on the corresponding field brightness under a large field angle, when the electronic device is shooting with a higher magnification, the display brightness of the high-magnification image is only adjusted based on the corresponding field brightness under a small field angle, and the field brightness corresponding to different field angles is different, so that the display brightness of the low-magnification image and the display brightness of the high-magnification image may have a larger difference.

The invention provides a shooting method which is applied to electronic equipment and comprises the steps of shooting at a first multiplying power, detecting a zooming shooting instruction, adjusting the first multiplying power to a second multiplying power by the zooming shooting instruction, wherein the second multiplying power is larger than the first multiplying power, acquiring a first image under the second multiplying power through a first camera, acquiring a second image under a third multiplying power through the first camera, wherein the third multiplying power is smaller than the second multiplying power, the display content of the first image corresponds to the display content of a first area in the second image, determining a first brightness value of the first image and a second brightness value of the second image, adjusting the first brightness value of the first image to a third brightness value based on the difference of the first brightness value and the second brightness value, adjusting the brightness value of each pixel point in the first image to obtain a third image based on the third brightness value, and displaying the third image. In the embodiment of the invention, in the process of shooting by the electronic equipment through the long-focus camera (such as the first camera), a high-magnification image (such as the first image) of the current magnification corresponding to the long-focus camera and a low-magnification image (such as the second image) of the smaller magnification corresponding to the current magnification smaller than the current magnification are obtained, when the shooting scene is a low-contrast scene, the image brightness of the high-magnification image is adjusted by taking the image brightness of the low-magnification image as a reference, so that the small difference of the image brightness in the shooting process of switching different magnifications of the same shooting scene by the electronic equipment is ensured, and when the shooting scene is a high-contrast scene, the image brightness of the high-magnification image is taken as a reference to adjust the image brightness of the high-magnification image, thereby avoiding the phenomenon of overexposure or underexposure of the high-magnification image. Therefore, the electronic equipment can adjust the high-magnification image only through the long-focus camera, the normally-open main camera is not needed, and the power consumption is low. In one possible implementation of the first aspect, adjusting the first luminance value of the first image to be the third luminance value based on the difference between the first luminance value and the second luminance value includes determining a first difference value between the first luminance value and the secon
