Problems solved by technology

[0003] HDR calculation is to combine two frames into one frame, and it must consume huge resources of the system, which will lead to the reduction of the maximum supported resolution specification of the product. At present, the HDR technology of multi-frame exposure in the market is realized by sacrificing the resolution.

Abstract

The embodiment of the present invention discloses a progressive exposure image generation method, comprising: obtaining current scene information, generating a global exposure time according to the scene information; obtaining at least one target exposure time function, Generate the target exposure time of the shooting content of each row of the target image, so that the target exposure time corresponding to the shooting content of each row is not equal; expose each row according to the target exposure time of the shooting content of each row, and obtain the shooting content of each row The target image is acquired according to the image data of the shooting content of each row. The invention also provides a progressive exposure image generation system, image processing equipment and media. The invention can effectively improve the image quality and improve the smoothness of video playing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image generation method, system, image processing device and medium of progressive exposure. Background technique [0002] High-dynamic range images (High-Dynamic Range, referred to as HDR), compared with ordinary images, can provide more dynamic range and image details, according to different exposure times of LDR (Low-Dynamic Range, low dynamic range images), And use the LDR image corresponding to the best detail at each exposure time to synthesize the final HDR image. It can better reflect the visual effect in the real environment. [0003] HDR calculation is to combine two frames into one frame, which itself must consume huge system resources, which will lead to a reduction in the maximum supported resolution specification of the product. Currently, the HDR technology for multi-frame exposure on the market is realized by sacrificing resolution. Contents...
