Imageprocessing

US12607433 - Method, apparatus, terminal, and storage medium for image processing

A method and device for image processing, a terminal and a storage medium. The method includes acquiring an image generated by an infrared sighting telescope arranged on a firearm; determining a grey level dynamic range of a preset first portion of the image; if a difference value between the grey level dynamic range value and the grey level of the preset second portion reaches a preset starting processing threshold, performing mean filtering processing on each pixel of the preset second portion to obtain a filtered grey level; and if the filtered grey level is greater than a preset grey level expectation threshold, processing the pixel, so that the grey level of the pixel is close to the grey level expectation value.
