Classification: CPC H  A | IPC A  H

Claim 0:
1. A medical image processing apparatus comprising:
an image sensor configured to capture an image of an 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 the observed object illuminated by the exciting light; and
an image processor configured to perform image processing on the captured image, wherein
a light receiving surface of the image sensor is 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,
the plurality of filter groups together transmitting white light,
each filter group of the plurality of filter groups transmits the exciting light and the fluorescent light,
the captured image includes plural pieces of first component information about colors corresponding to the spectral characteristics of the plurality of filter groups, respectively, and
the image processor is 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.
