Abstract
An image processing device and method, and an image display device and method which realizes a high-definition displayed video by reducing motion blur caused by a holding-type display system and reducing motion blurs of the displayed video caused by the time integration effect of an image sensor while suppressing deterioration of an image. The image display device includes a motion vector detection section () which detects a motion vector in each predetermined region between the frames of an inputted image signal, and an edge emphasis part () which emphasizes the high-frequency component of the inputted image signal and an interpolated image signal generated by an FRC part () according to the motion amount of the inputted image signal detected by the motion vector detection section (). This compensates the high-frequency component attenuated by the time integration effect of the image sensor to reduce the apparent motion blurs to improve the sharpness of the displayed image. By making the degree of edge emphasis of the interpolated image signal smaller than that of the inputted image signal, the sharpness of the displayed image is improved without making the image deterioration of the interpolated image signal distinct.
