IMAGE DISPLAY DEVICE, VIDEO SIGNAL PROCESSING DEVICE, AND VIDEO SIGNAL PROCESSING METHOD

摘要

Provided is an image display device which can suppress degradation of image quality attributed to a motion vector detection accuracy when performing a video signal processing for a predetermined image quality improvement. By considering reliability upon detection of a motion vector mv by a motion vector detector (44), an interpolation unit (45) performs a video signal processing in an imaging blur suppressing unit (13) and an overdrive unit (10). More specifically, setting is performed so that a processing amount upon a video signal processing becomes greater as the reliability becomes higher. On the other hand, setting is performed so that the processing amount upon the video signal processing becomes smaller as the reliability becomes lower. Even if a motion vector search range (a range for which block matching is performed) is exceeded when performing video signal processing by using a motion vector, it is possible to perform a video signal processing in accordance with the motion vector detection accuracy.
