Problems solved by technology

Therefore, for example, in the case where the target voltage for white display, black display, etc. is close to the limit of the voltage range (in the case where the gray scale is changed in a high gray scale area and a low gray scale area), there is a problem that there may be A voltage high enough to increase the response speed of liquid crystal cannot be applied, and the effect of suppressing motion blur may not be sufficiently exhibited

[0078] Improvements for motion blur measures (measures)

[0079] Before describing the preferred embodiment (first embodiment) of the present invention, the image processing device according to the embodiment of the present invention will be conceived by the present inventor as a solution to motion blur in a hold type display device such as a liquid crystal display device. Describe the process of improvement measures.

[0080] As described above, in the hold type display device, motion blur such as blurring of the leading edge, trailing of the rear eye, and delay in perceived position occurs in a moving object. Conventionally, motion blur is considered to be caused by slow response speed of display elements such as liquid crystals. ...

Abstract

The present invention provides an image processing device and an image display system achieving image quality improvement in moving picture by suppressing a motion blur in a hold-type display device, while maintaining low cost. The image processing device processes image data provided from outside and outputting the image data to a hold type display device. The image processing device includes a correction processing section performing a correction process to correct a pixel value in the image data for each pixel through performing a spatial HPF (high pass filter) process on the image data in a frame to be displayed in the display device according to a magnitude of a motion vector in the image data, the HPF process allowing an overshoot region and an undershoot region to be provided in a vicinity of both ends of the changing edge portion in the image data.

Description

technical field [0001] The present invention relates to an image processing device that processes image data input from the outside and outputs the image data to a hold type display device, and an image display system including the image processing device. Background technique [0002] In recent years, low-profile displays such as liquid crystal displays (LCDs) have widely spread instead of CRTs (cathode ray tubes), and techniques for displaying moving images on LCDs have attracted attention. [0003] Unlike an impulse type display device such as a CRT, when a moving image is displayed in a hold type display device such as an LCD, a plurality of frames or fields (hereinafter, simply referred to as "frames" ) to maintain the display of all the pixels making up the screen during the time period until when the next frame to be displayed is designated. Therefore, in the hold type display device, due to the so-called eye trace integration (afterglow characteristic exhibited in t...
