Claim Text:
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.
