Problems solved by technology

Specifically, when the liquid crystal display panel is viewed obliquely and from the front, brightness and chromaticity are different from each other
In particular, if Figure 9 As shown, in the VA mode liquid crystal display panel, the luminance of the output signal relative to the luminance of the input signal when viewed obliquely is higher than the luminance of the output signal relative to the luminance of the input signal when viewed from the front, so-called whitening. question

Embodiment Construction

[0053] Hereinafter, one embodiment of the present invention will be described using the drawings.

[0054] figure 1 It is a block diagram showing a schematic configuration of the display device 1 of the present embodiment. As shown in the figure, the display device 1 includes an image processing device 10 and a liquid crystal display panel (display unit) 2 .

[0055] The image processing device 10 includes a resolution improvement circuit (resolution improvement processing unit) 11 , a redistribution circuit (redistribution processing unit) 12 , and a liquid crystal drive circuit 13 .

[0056] The resolution improvement circuit 11 performs resolution improvement processing on the video signal X (image data) input to the image processing device 10 , and outputs the resolution-improved image data to the redistribution circuit 12 . In addition, the resolution improvement circuit 11 internally includes a division processing unit (not shown) that divides input image data into a ...

Abstract

The present invention provides an image processing device, a display device, an image processing method, a program and a recording medium. The image processing device (10) comprises an up-scale circuit (11) for up-scaling the resolution of a picture signal (X) (input image data) to high resolution is provided with a redistribution circuit (12) for redistributing the gradation values of the respective plural divided pixels up-scaled in the up-scale circuit (11) corresponding to one pixel of the picture signal (X) between the plural divided pixels. As a result, the image processing device for converting the resolution of the input image data into high resolution generates a high-resolution image and improves a view angle.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method that increase the resolution of input image data to high resolution. Background technique [0002] For a long time, the problem of the viewing angle characteristics of the liquid crystal display panel has been mentioned. Specifically, it is a problem that brightness and chromaticity differ from each other when viewing the liquid crystal display panel obliquely and from the front. In particular, if Figure 9 As shown, in the VA mode liquid crystal display panel, the luminance of the output signal relative to the luminance of the input signal when viewed obliquely is higher than the luminance of the output signal relative to the luminance of the input signal when viewed from the front, so-called whitening. question. [0003] As a method for solving the problems related to such viewing angle characteristics, for example, a pixel division method described in Patent...
