Abstract:
1. A device comprising: a first converter for converting first image data of an RGB-type into second image data of a YCbCr-type; a second converter for converting the second image data into third image data of the YCbCr-type; and a third converter for converting the third image data into fourth image data of the RGB-type, wherein a CbCr-coordinate system having an X-axis corresponding to a Cb value and a Y-axis corresponding to a Cr value is divided into six regions by straight lines respectively extending from coordinates of a reference color to coordinates of six primary colors arranged in a clockwise direction around the coordinates of the reference color, the six primary colors comprising a first primary color and a second primary color successively arranged in the clockwise direction with respect to the coordinates of the reference color, and wherein when coordinates of the second image data are located in a region having a boundary defined by straight lines respectively extending from the coordinates of the reference color to coordinates of the first primary color and to the coordinates of the second primary color, the coordinates of the second image data are determined by the coordinates of the reference color, the coordinates of the first primary color, the coordinates of the second primary color, coordinates of a target reference color corresponding to the coordinates of the reference color, coordinates of a first target primary color corresponding to the coordinates of the first primary color, and coordinates of a second target primary color corresponding to the coordinates of the second primary color.
