Abstract

The invention provides an image shooting method and device, an image processing method and device, electronic equipment and a computer readable storage medium. The image shooting method comprises the steps of collecting visible light images corresponding to multiple different exposure values of a shooting object through a first camera; acquiring a plurality of infrared images respectively corresponding to the visible light images corresponding to the plurality of different exposure values through a second camera; carrying out registration on the plurality of infrared images to obtain an offset matrix; registering the plurality of visible light images corresponding to the different exposure values according to the offset matrix to obtain a plurality of registered visible light images; and fusing the plurality of registered visible light images to obtain a fused image. According to the embodiment of the invention, the method can achieve the registration of the visible light image through the offset matrix of the infrared image, solves a problem that the registration is difficult to achieve due to the large brightness difference between images with different exposure values, improves the registration speed and precision of different exposure images, and improves the imaging effect of a multi-exposure image.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, relates to an image capturing method, an image processing method, a device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of mobile terminal technology, users have higher and higher requirements for the quality of photos taken. As a highlight function, night scene photos have also attracted the attention and love of many users. [0003] The strategy often used in the existing super night scene algorithm is to fuse images with different exposure values ​​in the same scene to achieve brightening of underexposed areas and darkening of overexposed areas, and then obtain more High dynamic range images for dynamic range and image detail. However, due to the large difference in brightness between images with different exposure values, and there are some factors such as over-exposure and under-exposu...
