METHOD FOR DYNAMICALLY MONITORING IMAGE QUALITY BY THE WAY OF DISPLAYING THE HISTOGRAM EXPOSURE TABLE ON THE MONITOR SCREEN

摘要

This invention discloses a method for dynamically monitoring an image quality by the way of displaying an histogram exposure table on the monitor screen, that the bright signal Y of digital television video data stream accepted by display device is divided into some bright levels in space and the pixel status distribution of the source of signal exposure is dynamically displayed on the display screen according to the content of every frame in the form of histogram by weight computation, thus the estimated reference for the image quality is provided to people and at the same time  dynamically monitoring the image quality could be achieved.
