Abstract:
1. An image input apparatus comprising: an imaging element for taking original image data containing at least three kinds of original image components, arranged with at least three kinds of pixels having different spectral sensitivities, a color space conversion section which converts the original image data into a color space including luminance signals and chromaticity signals, and a color signal generating section which generates RGB color signals from the original image components, wherein the color space conversion section generates a second intensity signal by converting the RGB signals into the color space and calculates the chromaticity signals of the color space by carrying out a mathematical operation using a first ratio which represents a ratio of the first intensity signal to the second intensity signal; wherein the color space conversion section calculates a first intensity signal, which can be obtained by carrying out an addition processing of the original image components, as luminous signals of the color space.
