Claim 14:
15. An image processing method executed by an image pickup apparatus, the image processing method comprising:
selectively transmitting, by a multi-band pass filter of the image pickup apparatus, band light in a specific band, wherein the band light corresponds to a plurality of color filter elements of a color filter of the image pickup apparatus;
transmitting, by the color filter, the band light in the specific band to each of a plurality of pixels of an image pickup device of the image pickup apparatus;
receiving, by the image pickup device, the band light transmitted by the multi-band pass filter and the color filter;
generating, by the image pickup device, a raw image based on the received band light;
generating, by a signal processing section of the image pickup apparatus, a plurality of raw image base pixel values based on the raw image from the image pickup device; and
generating, by the signal processing section, a true pixel value, corresponding to the specific band, of each of the plurality of pixels based on the generated plurality of raw image base pixel values and a spectral characteristic parameter of the image pickup apparatus, wherein
the spectral characteristic parameter of the image pickup apparatus is an intensity ratio of a signal transmitted by a first color filter element of the plurality of color filter elements to a signal transmitted by a second color filter element of the plurality of color filter elements in the specific band of the multi-band pass filter.
