Image processing apparatus and computer readable medium for image processing

A computer-readable recording medium storing an image processing program to cause a computer to function as:

• an input unit to input a fluorescent image and a morphological image of a tissue, wherein
• a specific biological substance expressed at a first structure of a cell in the tissue is stained by a fluorescent substance,
• the fluorescent image illustrates at least one fluorescent bright point which represents expression of the biological substance in the tissue, and
• the morphological image illustrates a morphology of a second structure of a cell in the tissue and comprises a same range of the tissue as the fluorescent image;
• a feature amount extraction unit to extract a feature amount of the second structure from the morphological image;
• a bright point extraction unit to extract the fluorescent bright point from the fluorescent image;
• and
• a region of interest determination unit to determine a region of interest on a basis of the feature amount of the second structure and a distribution of the fluorescent bright point.
