Abstract

An image processing device, method, an image display device and method which can obtain a high-definition display image by properly controlling processing of reducing the blur of a displayed image caused by the time integration effect of an imaging device. The image display device comprises a motion detection part (1) which detects the moving amount of an input image signal, and an edge emphasis part (2) which subjects the input image signal to edge emphasis processing, and the image display device increases an edge emphasis degree of edge emphasis processing to an area where the moving amount of the input image signal is large. The image display device comprises a genre judgment part (3) which judges the genre classification which the input image signal is connected with according to genre information obtained from outside of the device, and a control part (4) which controls the edge emphasis part (2) to reduce the edge emphasis degree of the edge emphasis processing or to avoid the edge emphasis processing even in the area where the moving amount of the input signal is large when the input image signal is connected with a predetermined genre.
