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 6):
The image processing apparatus according to  claim 1 , wherein the retinex processing of the retinex unit is performed on the basis of computation results of a first output obtained by applying a specular reflection component (specular component) filter to the input image signal, a second output obtained by applying a diffuse reflection component (diffuse component) filter to the input image signal, and a third output obtained by applying an ambient light component (ambient component) to the input image signal, and\n the retinex unit has\n a first detection unit that detects the specular reflection component on the basis of the first and second outputs, \n a second detection unit that detects the diffuse reflection component on the basis of the second and third outputs, and \n a reflection light generator that generates a reflection light component on the basis of the specular reflection component and the diffuse reflection component.
