Abstract:
An image processing system, comprising:coding means for separating a signal provided by an image pickup device with a color filter into a luminance signal and a contour correcting signal, said coding means including: a horizontal low pass filter to provide said luminance signal, a first filter operable on said luminance signal to provide a horizontal direction contour correcting signal, a second filter operable on the signal derived from said image pickup device to provide a vertical direction contour correcting signal, a gain adjust unit operable on the horizontal and vertical direction contour correcting signals to provide a gain-adjusted contour correcting signal, and compression means for separately compressing the luminance signal and the contour correcting signal; a transmission path with band limitation for transmitting said luminance signal and said contour correcting signal compressed by said coding means; and decoding means for separately expanding said luminance signal and said contour correcting signal transmitted through said transmission path and for adding and outputting said signals.
