Abstract: A diagnostic apparatus for diagnosing a disease using a captured image of an affected area, the apparatus including a memory configured to memorize the captured image; and a processor configured to process the memorized image memorized in the memory. The processor is configured to perform a highlighting process which includes separating the captured image into the brightness component and a color information component; separating the brightness component into a base component and a detail component; highlighting the separated brightness component; and adding a region to be diagnosed in the captured image to the highlighted brightness component while a specified color of the region to be diagnosed is maintained.

Abstract: A diagnostic apparatus for diagnosing a disease using a captured image of an affected area includes an image-memorizing unit configured to memorize the captured image and a processing unit configured to process the captured image memorized in the image-memorizing unit. The processing unit includes a separating unit configured to separate the captured image into a brightness component and a color information component, an extracting unit configured to extract a region to be diagnosed based on the brightness component or the color information component of the captured image to highlight likeness of the region, and a highlighting unit configured to highlight the extracted region in accordance with the extracted likelihood V representing the likeness of the region.

Abstract: The invention provides a method of processing an image in a diagnostic apparatus 100 of diagnosing a disease using a captured image of an affected area, comprising: a memorizing step of memorizing the captured image (Step S12), and a processing step of processing the captured image memorized (Step S13), wherein in the processing step a region to be diagnosed is subjected to a highlighting process with a specified color thereof maintained.
