Image processor for correcting distortion of central portion of image and preventing marginal portion of the image from protruding

摘要

A distorted optical image formed on an image pickup surface by an optical system is photoelectrically converted by an image pickup device and written in memory cells of an image memory designated by write addresses. When the optical image is read, the image quality at the central portion is improved and the image is prevented from missing at the marginal portion so that the image can preferably be observed by correcting the distortion of an image in the area at the central side of the image pickup surface due to the optical system by read addresses obtained by converting the write addresses and preventing an image in the area at the marginal side from protrusion.
