IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
First Claim
1. An image processing apparatus, comprising:
- an interface unit configured to input an image signal from an imaging apparatus that exposes a specimen dyed with a fluorescent dye to excitation light and images fluorescence by a color imaging element; and
a color correction circuit configured to retain information on a percentage of each of a component of a second color and a component of a third color with respect to a component of a first color corresponding to the excitation light in the image signal, which is determined in advance based on color filter spectral characteristics of the color imaging element, and reduce each of an amount corresponding to the percentage of the component of the second color and an amount corresponding to the percentage of the component of the third color from the input image signal.
