Abstract

The invention provides a video image enhancement system. The system comprises a video image collection unit, a video image processing unit and a video image displaying unit which are connected in sequence. The video image collection unit is used for collecting video images in real time. The video image processing unit comprises a digital signal processor and a CPLD co-processor which are connected. The digital signal processor is connected with the video image collection unit and is used for obtaining gray component images in the original images. The CPLD co-processor is used for carrying outgray value correction on pixels of the gray component images according to a relative light and shade relationship between the pixels of the gray component images and the pixels of the gray component images after gaussian smoothing, and synthesizing the gray component images after the gray value correction, thereby obtaining enhanced images. The video image displaying unit is connected with the CPLD co-processor and is used for displaying the enhanced images.

Description

technical field [0001] The invention relates to the field of video image data processing, in particular to a video image enhancement system. Background technique [0002] When light propagates in fog, haze and other media, due to the scattering effect of particles, the image information collected by the imaging sensor is seriously degraded, such as: low brightness, low contrast, narrow dynamic range, and unclear details; the color of natural scenery is not clear , the saturation is reduced, the image becomes gray, and even color shift occurs. The above defects in the video image monitoring technology limit the application value of the video image to a large extent, and will bring great difficulties to the outdoor video image acquisition and processing system, and even fail to work normally. information brings great inconvenience. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, thereby providing a v...
