METHOD AND SYSTEM FOR AUTOMATICALLY DECIDING LIGHT DECREASING LEVEL IN IMAGE

摘要

PROBLEM TO BE SOLVED: To provide ability of executing light decrease correction without requiring the data input on the external environment. SOLUTION: An image processing system has an image collector and a light decrease correcting system. The correcting system has a polar converter which converts an image into a radiation trace and a decrease fitter which adapts the radiation trace to a decrease model which is used for deciding the correction of the light decreasing amount of an image.
