PROBLEM TO BE SOLVED: To reduce an image data buffer memory capacity without greatly increasing a circuit scale and a processing time in processing for correcting a distortion aberration in an on-the-fly manner.SOLUTION: An image processor 10 of this invention includes: an image data buffer 13 for storing at least image data represented by a first coordinate axis and a second coordinate axis in an area unit divided in a first coordinate axis direction; a buffer control unit 12 for controlling a writing or reading operation of the image data in/from the image data buffer; and a distortion aberration correction unit 14 for correcting a distortion aberration of the image data stored in the image data buffer. The buffer controller 12 performs control for writing the image data in the image data buffer in a buffer size necessary for distortion aberration correction in the area unit.SELECTED DRAWING: Figure 1 【課題】オンザフライで歪曲収差を補正する処理において、回路規模や処理時間の大幅な増加なしに、画像データバッファメモリ容量を削減すること。【解決手段】本発明の画像処理装置１０は、少なくとも第１座標軸と第２座標軸で表される画像データを、第１座標軸方向で区分された領域単位で記憶する画像データバッファ１３と、画像データバッファに画像データを書き込むまたは読み出す動作を制御するバッファ制御器１２と、画像データバッファに記憶された画像データの歪曲収差を補正する歪曲収差補正器１４と、を備え、バッファ制御器１２は、領域単位で歪曲収差補正に必要なバッファサイズで画像データを画像データバッファに書き込む制御を行う。【選択図】図１
