<p>An imaging system comprising a color conversion unit (7) for converting a primary-color or complementary-color signal from a CCD (2) into a signal, in a color space, constituted of luminance, hue and chroma, a gradation correction unit (8) for subjecting a luminance signal to gradation conversion, a correction factor calculation unit (11) for calculating a chroma correction factor used to correct a chroma signal, a maximum chroma calculation unit (9) for calculating a first maximum chroma value for a luminance signal and a hue signal from the color conversion unit (7), and a second maximum chroma value for a hue signal from the color conversion unit (7) and a luminance signal converted by the gradation correction unit (8), and a chroma correction unit (15) for calculating a correction factor based on the first and second maximum chroma values, and correcting a chroma signal based on this correction factor and a chroma correction factor from the correction factor calculation unit (11).</p> |
