Abstract:
1. An image sensing apparatus adapted to perform color suppression of an image data signal, comprising: a white balance unit that adjusts the image data signal and outputs white balance adjusted image signal; a chroma composition ratio determination unit arranged to determine a chroma composition ratio (α:β:γ) required for color suppression of the white balance adjusted image signal based on a red signal R, a green signal G and a blue signal B contained in the white balance adjusted image signal; a signal generator arranged to generate a chroma suppression signal (Ya) of the white balance adjusted image signal based on the chroma composition ratio; a color suppression rate determining unit arranged to determine a color suppression rate based on the chroma suppression signal; and a color suppressor arranged to perform color suppression on the white balance adjusted image signal based on the color suppression rate, wherein the chroma composition ratio determination unit sets the chroma composition ratio of a signal indicating the minimum value among the red signal, green signal and blue signal as 1, and sets the chroma composition of signals other than the minimum value as 0.
