Problems solved by technology

[0005] However, in the above-mentioned method, pixels in half of the horizontal lines in each field are turned into black images, so the brightness (brightness) of the displayed image of one frame is theoretically attenuated to half of the brightness of the original image of one frame, so that the contrast reduce

Abstract

The present invention relates to signal processing for motion blur improvement. The image memory of the present invention sequentially stores input image data of a plurality of frames inputted. The writing control unit controls writing to the image memory. The read control unit controls read from the image memory. The drive image data control unit generates the drive image data based on read image data sequentially read from the image memory. The drive image data generation unit replaces at least a part of the read image data with mask data to generate the drive image data. The pixel value indicated by the mask data is determined based on the pixel value indicated by the read image data corresponding to the pixel to be replaced by the mask data. In this way, it is possible to improve the blurring of moving images that occurs in the image display device, and suppress the attenuation of the brightness level of the displayed image.

Description

technical field [0001] The present invention relates to a signal processing technology for improving the blurring of moving images in a storage type display device typified by a liquid crystal display device. Background technique [0002] A liquid crystal display device using a liquid crystal panel is widely used at present. This liquid crystal display device is an image display device in which each pixel is constituted by a memory type display element (hereinafter referred to as a memory type display device). The storage type display device has a low-pass filter time-frequency characteristic in which the response characteristic in the high-frequency region of the signal frequency is reduced. Therefore, when a moving image is displayed by the liquid crystal display device, there is a frequency corresponding to the moving speed of the object in the moving image. There is a problem that the ground image is blurred (hereinafter referred to as blurring of moving image or blurri...
