Claim Text:
1. A system that extracts a region of interest from an image, the region extraction system, having: an input unit that accepts inputs of the region of interest and an object image; an algorithm management dissection database that stores an optimum algorithm and an unknown quantity including parameter for extracting the region of interest; a region extraction unit that acquires the algorithm and the parameter stored in the algorithm management dissection database with entry of the region of interest and the object image and executes region extraction processing for the region of interest by applying the algorithm and the parameter so acquired to the object image; a luminance distribution analyzing unit that outputs an unknown quantity parameter by calculating a luminance distribution of the region of interest with entry of the region of interest and the object image; a luminance distribution management database that stores similarity in luminance distribution of biological tissues; a region extraction pre-processing unit that performs pre-processing for obtaining the unknown quantity parameter with entry of the object image, and the algorithm and the parameter stored in the algorithm management dissection database; and a display unit that displays a result of extraction, wherein in the region extraction unit, in a case where the unknown quantity is included in the parameter so input, an optimum value of the parameter is acquired from the luminance distribution analyzing unit.
