IMAGE PROCESSOR, IMAGE PROCESSING METHOD, IMAGE PROCESSING PROGRAM AND RECORDING MEDIUM WITH IMAGE PROCESSING PROGRAM RECORDED THEREON, AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image processor suitably reducing jaggy of an image contour during four-color reproduction.

SOLUTION: The image processor outputs image data of four colors to a display section using display pixels each comprising four sub-pixels. Specifically, a color converting means color-converts image data of three colors into image data of first four colors while maintaining the number of display pixels of the image data of the three colors. A converting means generates image data of second four colors having the same data amount with the image data of the three colors by applying interpolation to the image data of the first four colors based upon the relationship between positions of sub-pixels of the image data of the first four colors and positions of sub-pixels at the display section. Consequently, when a pixel configuration which does not decrease a numeral aperture is employed, the jaggy of the image contour can suitably be reduced during four-color reproduction.
