Abstract

The invention embodiment provides an image optimizing method used by an electronic device; the method comprises: firstly receiving an image having a plurality of pixel values, and each pixel value can be divided into two channels; the image is cut into a plurality of blocks, and a selected channel is arranged on each block; the pixel value of the selected channel is adjusted according to at least one arrangement matched with at least one adjacent block, and the pixel value of other channels are adjusted according to the adjusted pixel value based on the selected channel; finally, the adjusted image is provided.

Description

technical field [0001] The invention relates to an image optimization method and a system using the method, especially a method for improving image quality by adjusting brightness and chrominance values ​​when capturing images under harsh conditions. Background technique [0002] Photographers will encounter many unfavorable conditions and uncontrollable locations when taking photos, resulting in poor quality images. For example, taking a photo when the light is directly behind the subject (eg, a person) (also known as a backlight situation) may cause the edges of the subject to be brighter but the subject itself remains dark. Or, shooting an object standing in a low-light location (also known as a low-light situation), causing the object to appear too dark in the captured image. When the lighting conditions are poor, the images captured by digital cameras are unsatisfactory. Accordingly, there is a need for an image processing method, which can improve the quality of the ...
