发明名称 COLOR CORRECTION DEVICE AND COLOR CORRECTION METHOD
摘要 <P>PROBLEM TO BE SOLVED: To provide a color correction device which ensures approximation to a memory color rather than faithful color reproduction for a specific color without having impact on other colors, and to provide a color correction method. Ž<P>SOLUTION: A color correction device includes a color space conversion section 1 for converting input image data into a plurality of types of color system in order to detect a specific color region, a specific color range detection section 2 for detecting a specific color based on the output from the color space conversion section 1, an average luminance level detection section 3 which detects an average luminance level for a region detected at the specific color range detection section 2, and a color correction section 4 which coordinates the color for the region detected at the specific color range detection section 2 according to the average luminance level detected at the average luminance level detection section 3 and outputs a corrected image. The specific color range detection section 2 compares the input image data converted into HSV data at the HSV conversion section of the color space conversion section 1 with preset specific color data and detects the perimeter colors of comparison data.
