Claim 11:
12. A medical image processing method comprising:
obtaining an image from an observed object illuminated with exciting light using an image sensor, the image including fluorescent light output from the observed object illuminated by the exciting light and exciting light reflected by the observed object illuminated by the exciting light, from a light receiving surface of the image sensor provided with a color filter in which a plurality of filter groups having spectral characteristics different from each other are arranged in a specific format, each filter group of the plurality of filter groups transmits the exciting light and the fluorescent light and the plurality of filter groups together transmitting white light;
generating first component information about colors corresponding to the spectral characteristics of the plurality of filter groups, respectively, that includes plural pieces of first component information, and
generating second component information by using at least one combination of two different pieces of first component information out of the plural pieces of first component information about the colors obtained by multiplying the two different pieces of first component information, and
color correction processing that corrects the plural pieces of first component information about the colors by multiplying an input matrix containing each of the plural pieces of first component information and the second component information as matrix elements by a color correction matrix so that a brightness of an exciting light component of the image and a brightness of a fluorescent light component of the image equals a predetermined balance.
