Problems solved by technology

This can lead to long image capture time and high memory consumption
At the same time, due to the displacement between the images under different exposure parameters, the images need to be aligned before fusion, which increases the complexity of the HDR algorithm.

Abstract

The invention provides a camera sensor design method based on an HDR algorithm. The camera sensor design method based on an HDR algorithm comprises: obtaining an exposure image by controlling acquisition of exposure parameters of each line; splitting the exposure image into a plurality of first sub-images; performing interpolation of the plurality of first sub-images through a bicubic interpolation algorithm to obtain a plurality of second sub-images; and fusing the plurality of second sub-images into a fusion image. The camera sensor design method based on an HDR algorithm can enhance the dynamic scope of images.

Description

technical field [0001] The invention relates to camera sensor technology, in particular to a camera sensor design method based on an HDR algorithm. Background technique [0002] The existing HDR algorithm is to set different exposure parameters, and collect multiple images under different exposure parameters, and then fuse the multiple images into one image. This can result in long image acquisition times and high memory consumption. At the same time, due to the displacement between the images under different exposure parameters, the images need to be aligned before fusion, which increases the complexity of the HDR algorithm. Contents of the invention [0003] The camera sensor design method based on the HDR algorithm provided by the present invention can enhance the dynamic range of the image. [0004] According to an aspect of the present invention, a kind of camera sensor design method based on HDR algorithm is provided, comprising: [0005] Obtaining an exposure ima...
