Claim 10:
11. A medical observation system comprising:
a light source device configured to emit exciting light to be incident on an observed object;
an imaging device including:
an image sensor configured to generate a captured image from the observed object illuminated with exciting light, the captured image including fluorescent light output from the observed object illuminated by the exciting light and exciting light reflected by from the observed object; and
a color filter in which a plurality of filter groups having spectral characteristics different from each other are arranged in a specific format, the color filter being provided in a light receiving surface of the image sensor, wherein the color filter transmits light in a wavelength region larger than and overlapping the exciting light and the fluorescent light; and

an image processor configured to
generate 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 multiplication of the two different pieces of first component information, and
perform 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 captured image and a brightness of a fluorescent light component of the captured image equals a predetermined balance.
