  • Patent number: 8253789
    Abstract: In a correction data storing unit of a digital camera which captures a microscopic image, image data of a light image without a sample, image data obtained by using a filter for removing a defective portion for the light image without a sample, image data where a region without being corrected (or a region being corrected) is set in the light image without the sample, and shading correction data calculated from image data obtained by setting a mask region where data after being corrected is set to 0 are stored. An operator obtains, captures, records, and stores an observation image satisfactory for great-looking by using arbitrary shading correction data. In this way, a captured image satisfactory for great-looking is obtained by making a suitable shading correction according to a shading characteristic, which is caused by an optical system.
