Patent ID: 8508455

Claim:
A video processing circuit for use with a liquid crystal display that includes pixels, the video processing circuit designating an applied voltage to be applied to at least one of the pixels based on a video signal, the video processing circuit comprising: a first boundary detection portion that analyzes a video signal of a first frame and detects a first boundary between a first pixel having a first applied voltage and a second pixel having a second applied voltage, the first pixel being disposed adjacent to the second pixel, the first applied voltage being lower than the second applied voltage; a second boundary detection portion that analyzes a video signal of a second frame preceding the first frame and detects a second boundary between a third pixel having a third applied voltage and a fourth pixel having a fourth applied voltage, the third pixel being disposed adjacent to the fourth pixel, the third applied voltage being lower than the fourth applied voltage; and a correction portion that corrects the first applied voltage to a fifth applied voltage if the first boundary is an applied boundary and the applied boundary does not exist at a position corresponding to a position of the second boundary, the fifth applied voltage being higher than the first applied voltage and the fifth applied voltage being lower than the second applied voltage.
