发明名称 SIGNAL PROCESSOR, DISPLAY DEVICE, AND SIGNAL PROCESSING METHOD
摘要 PROBLEM TO BE SOLVED: To provide a signal processor that can suitably reproduce pure colors, and uses a lookup table for color mapping with an easy interpolation method for color space data for colors which do not correspond to a grating point.SOLUTION: A signal processor 1 comprises: a lookup table storage part 23 which stores a lookup table comprised of grating points specified by equal packing of an HSV color space, color space data for colors corresponding to the grating points being tabulated; a first color space conversion part 21 which converts a color space of colors of an input video signal into a linear color space; and a color mapping part 22 which extracts color space data for grating points corresponding to colors of a video signal in the linear color space or extracts color space data for grating points nearby the colors of the video signal in the linear color space, and interpolates color space data for the colors of the video signal in the linear color space using the extracted color space data.SELECTED DRAWING: Figure 2
