Abstract

The invention provides an image generation method and device, and terminal equipment. An image sensor that is provided in advance includes a photosensitive pixel array and an optical filter arranged on the photosensitive pixel array, the optical filter includes a filtering unit array, each filtering unit covers m*n photosensitive pixels which form a merged pixel, m*n>1, brightness information of a photographing environment is obtained, a unit pixel quantity P corresponding to the brightness information is determined according to a preset strategy, 1<=P<=m*n, and outputs of a plurality of photosensitive pixels which belong to a same merged pixel is correspondingly processed according to the unit pixel quantity, thereby generating an image of corresponding resolution. Adjustment of the light inlet quantity of a unit pixel is realized through dynamic adjustment of the unit pixel quantity according to the brightness condition of the photographing environment, and the image of corresponding resolution is generated, thereby suppressing noisy points of the image, and improving definition of the image.

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...
