Abstract:
An image signal is subjected to image correction performed by an image correction unit on the basis of retinex processing. The image correction unit performs spectral decomposition for the image signal. A retinex unit performs retinex processing for the image signal subjected to the spectral decomposition, and a spectrum synthesis unit synthesizes the image signal output from the retinex unit. A transformation unit performs transformation from a RGB color space to a HSV color space, and an inverse transformation unit performs transformation from the HSV color space to the RGB color space. The transformation unit transforms an input image signal and outputs the transformed image signal to the spectral decomposition unit. The inverse transformation unit receives the output signal from the spectrum synthesis unit and outputs an image correction signal. Spectral decomposition of the image signal in the spectral decomposition unit is hue-based spectral decomposition in the HSV color space.

Claim (Index 7):
The image processing apparatus according to  claim 6 , wherein, in the retinex processing of the retinex unit, the ambient light component filter is a filter based on a normal distribution.
