Abstract
A judgement section (10) and a ratio calculation section (11) in an image processing apparatus input image signals in digital form of n color components forming colors, transferred externally in time series, and calculate conversion parameters indicating change of ratios of signal strength values between input image signals per color component based on a total sum of the ratios of synthesis signal values, each conversion section (12, 13, 14) and a signal range calculation section (15) converts input image signals to output image signal without any change of the ratio of signal strength values between the input image signals based on the conversion parameters, per color component.
