Abstract

The present invention proposes an image generation method, device, and terminal equipment, wherein the pre-provided image sensor includes: an array of photosensitive pixels, and a filter set on the array of photosensitive pixels, and the filter includes an array of filter units, each The filter unit covers m*n photosensitive pixels and forms a merged pixel, m*n>1; by obtaining the brightness information of the photographing environment, the unit pixel quantity P corresponding to the brightness information is determined according to a preset strategy, wherein, 1< =P<=m*n; correspondingly process outputs of multiple light-sensitive pixels belonging to the same binning pixel according to the unit pixel amount, and then generate an image with a corresponding resolution. It realizes the dynamic adjustment of the unit pixel amount according to the light conditions of the shooting environment to adjust the light input amount of the unit pixel, and generates an image of the corresponding resolution, thereby suppressing image noise and improving image clarity.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image generation method, device and terminal equipment. Background technique [0002] With the development of smart terminals, there are more and more terminal devices, such as mobile phones, IPADs, wearable smart devices, etc. [0003] Taking pictures contains many tiny components, among which the image sensor is a key factor in determining the image quality. However, the light in the photographing environment changes in real time, and the images generated by existing image sensors in low-light environments have excessive image noise, resulting in unclear images and other deficiencies. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] Therefore, the first object of the present invention is to propose an image generation method, which can dynamicall...
