Title:

IMAGE PROCESSING DEVICE

Document Type and Number:

WIPO Patent Application WO/2004/032524

Kind Code:

A1

Abstract:

Automatic color adjustment is performed with little side effect for the storage color. An image processing device corrects a color of a particular range of an image signal for each of pixels contained in an input image signal. The image processing device includes: intensity decision means (200A) for generating correction intensity with small intensity at periphery and large intensity in the vicinity of the center for a color region of a particular range according to two chromaticity signals excluding a luminance component among the pixel signals; target color setting means (400A) for setting a target color for correcting the pixel signal; correction degree setting means (600) for setting a correction degree by using information other than on the image information contained in the pixel signal; and correction means for setting the image signal near the target color according to the correction intensity output by the intensity decision means (200A) and the correction degree output by the correction degree setting means (600).
