Title:
IMAGE DATA PROCESSOR
Document Type and Number:
Japanese Patent JP3895878
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To conduct white balance control and moire balance control in common.
SOLUTION: A separation circuit 22 generates complementary color data C[Ye], C[Mg], C[Cy] for an image signal D2 whose gain for each color component is arranged by a color balance control circuit 20, and a luminance arithmetic circuit 27 generates luminance data. Two of the complementary color data C[Ye], C[Mg], C[Cy] are multiplied by multiplier circuits 23a-23c, root, extraction circuits 24a-24c calculate roots of products P[r], P[g], P[b]. The roots P[R], P[G], P[B] are regarded as primary color data and fed to a color difference matrix circuit 26.
