摘要

A video processing circuit detects a risk boundary, which a portion of the boundary between a dark pixel and a bright pixel in an image represented by a video signal Vid-in, and is determined by a tilt azimuth of liquid crystal molecules, from the boundary, and corrects a video signal corresponding to at least one of the dark pixel and the bright pixel which is contiguous to the detected risk boundary in at least one field of a plurality of fields constituting one frame such that a period in which the risk boundary is present in one frame period is shortened.

主权项

1. A video processing method which corrects a video signal, the method comprising:
specifying a voltage to be applied to a liquid crystal element for each pixel and defines the voltage to be applied to the liquid crystal element on the basis of the corrected video signal, the method comprising: a risk boundary detection step of detecting a risk boundary which is a portion of the boundary between a first pixel whose applied voltage specified by the video signal falls below a first voltage and a second pixel whose applied voltage exceeds a second voltage higher than the first voltage, and is determined by a tilt azimuth of the liquid crystal; and a correction step of correcting the video signal, in at least one field of a plurality of fields constituting one frame so that a period in which the risk boundary is present in one frame period is shortened, wherein in one field of one frame the video signal is corrected, whereas in other field of the one frame the video signal is not corrected.
