Claim 0:
1. An image pickup apparatus, comprising:
an image pickup device that includes a plurality of pixels;
a color filter that includes a plurality of color filter elements;
a multi-band pass filter configured to selectively transmit band light in a specific band, wherein
the band light corresponds to the plurality of color filter elements,
the color filter is configured to transmit the band light in the specific band to each of the plurality of pixels of the image pickup device, and
the image pickup device is configured to:
receive the band light transmitted by the multi-band pass filter and the color filter; and
generate a raw image based on the received band light; and

a signal processing section configured to:
receive the raw image from the image pickup device;
generate a plurality of raw image base pixel values based on the raw image received from the image pickup device; and
generate 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 represents 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.
