Patent ID: 7236627

Claim:
An image sensing apparatus which has an image sensing element, an A/D conversion section which converts an output from the image sensing element, an image processing section which processes digital image data obtained from the A/D conversion section, a conversion section which converts the digital image data into output image data by image-processing in said image processing section, and a recording section which records the output image data to a recording medium, wherein said image processing section comprises a white balance processing section which executes the white balance processing in the digital image data by using white balance coefficients, a matrix arithmetic processing section which executes a matrix arithmetic processing by changing a coefficient in accordance with a color temperature of a light source, and a three-dimensional lookup table arithmetic processing section which performs a color conversion of a specific color by using a parameter according to a lattice point of three colors, and wherein said image processing section performs a white balance processing, a matrix arithmetic processing, and a three dimensional lookup table arithmetic processing in the order named.
