Abstract
A method of regional color processing based on video content and a system using the same are provided, comprising: step 1: dividing a data area; step 2: denoising pixel video data; step 3: generating a representative value of small block; step 4: detecting a video scene type; step 5: smoothing of the representative value of the small block; step 6: dark block fading processing; step 7: HDR custom compensating/definition restoring; and step 8: generating a representative value of the large block. It divides the video source data into small blocks or large blocks according to the rendering granularity of the ambient light, and implements algorithms such as noise reduction, smooth processing and adaptive compensation according to the video format and content, and the lighting rendering can follow the video signal in real time, which can effectively reduce the sudden change of rendering light and bring users more soothing experience.
