A main calculation unit generates emphasized Y luminance data by performing luminance emphasis processing on only Y luminance data included in YUV data representing an image of one frame. Further, the main calculation unit generates blurred Y luminance data by performing luminance blur processing on only the Y luminance data. In this way, it is possible to perform processing for improving the display quality of a moving picture in a shorter time period.

Display device

A display device is configured to divide one frame into a first-half sub-frame and a second-half sub-frame and display an image in each of the first-half sub-frame and the second-half sub-frame. The display device includes a pixel-of-interest specifying unit, a first peripheral pixel specifying unit, a first difference coefficient determination unit, a first coefficient determination unit, a first pixel value determination unit, a second peripheral pixel specifying unit, a second difference coefficient determination unit, a second coefficient determination unit, and a second pixel value determination unit. As a first coefficient and a second coefficient equal to each other are larger, a difference between an output pixel value corresponding to an input pixel value in a first conversion data and an output pixel value corresponding to the identical input pixel value in a second conversion data is larger.
