CIRCUIT AND METHOD OF PROCESSING IMAGE AND DEVICE OF PLASMA DISPLAY PANEL AND METHOD OF DISPLAYING IMAGE USING PLASMA DISPLAY PANEL

摘要

A video processing circuit for preventing generation of contour noise irrespective of varied directions of light emission schemes. A first video signal and a second video signal delayed by a predetermined field are received, a first motion detection result is output when a signal level of the first video signal is greater than that of the second video signal, and a second motion detection result is output if the second video signal is greater than the first video signal. A flag is established according to the first motion detection result, and a third video signal generated by delaying the first video signal is output. The lighted pattern of the third video signal is switched according to the second motion detection result and the flag.
