HUMAN VISUAL SYSTEM TYPE IMAGE PROCESSING METHOD

摘要

PURPOSE: A human visual system type image processing method is provided to produce high distribution of sensors at a visual center part and uniform image pixel sensitivity using a linear CCD sensor and a rotary prism. CONSTITUTION: A linear CCD sensor is rotated or fixed, a dove prism is employed, and polar coordinate transform mapping is used. To raise density of visual cells with respect to the center of an image to be processed and construct an image with uniform sensitivity, the polar coordinate transform mapping, which converts data of orthogonal coordinate system into data of polar coordinate system, is used. The linear CCD sensor(12) is rotated or fixed to obtain the data of polar coordinate transform mapping.
