Document Type and Number:
Japanese Patent JP4668956
Kind Code:
B2
Abstract:
An image processing apparatus and method capable of improving illuminant estimation accuracy and performing a stable white balance correction. A specific subject detection unit detects a specific subject having a specific color from assigned image data. A specific chromaticity calculation unit calculates a specific chromaticity from data representing the specific color of the specific subject. Then, a standard chromaticity that approximates to the calculated specific chromaticity is determined from standard chromaticities. A chromaticity difference calculation unit calculates one or more sets of chromaticity difference information representing a chromaticity difference from the determined standard chromaticity to the calculated specific chromaticity. A white chromaticity correction unit obtains one or more white chromaticities corresponding to the selected one or more standard light sources and corrects the one or more white chromaticities by referring to the one or more sets of chromaticity difference information.
