Abstract
A motion vector display circuit includes a motion vector detection circuit that detects a motion vector between frame images, and a norm calculation circuit that calculates the length of a motion vector detected by the motion vector detection circuit. The length of the detected motion vector is converted into a luminance component of a display signal, a first component of the motion vector is converted into a first chrominance component of the display signal, a second component of the motion vector is converted into a second chrominance component of the display signal, and the motion vector is displayed using the display signal.
