An image sensing apparatus for a microscope of this invention includes an
image sensing unit for sensing an observation image obtained by a
microscope and obtaining the observation image, a microscopy technique
determination unit for detecting a microscopy technique in the microscope,
a chromaticity determination unit for determining chromaticity of the
observation image on the basis of the microscopy technique detected by
said microscopy technique determination unit, and determining a region
where color balance is adjusted in the observation image, and a color
balance adjustment unit for adjusting color balance in accordance with a
color balance adjustment amount arbitrarily set for the region of the
observation image determined by said chromaticity determination unit.
