Classification: CPC H  G | IPC H

Claim 15:
16. An image processing method executed by an image processing apparatus, the image processing method comprising:
receiving a raw image from an image pickup device of a multispectral camera, wherein
the raw image is based on band light in a specific band transmitted by each of a multi-band pass filter and a plurality of color filter elements of the multispectral camera, and
the band light is transmitted by the plurality of color filter elements to each of a plurality of pixels of the image pickup device;

generating a plurality of raw image base pixel values based on the raw image; and
generating 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 multispectral camera, wherein
the spectral characteristic parameter of the multispectral camera 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.
