IMAGE RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an image recording device capable of revising image data taken by an on-vehicle camera when a user travels on a road in case that there exist different information after comparison with existing map information.

SOLUTION: A reference vector and the vector between two points which are optionally selected are calculated so as not to be in parallel with each other in the storage image data of an image to be detected which is stored in a detection target image storage device 106. New correlation storing image data are generated by changing the scalars of the vectors and the directions thereof. The image data of the image to be detected which is stored in the storage device 106 and the image data taken in by an image taking means 10 are compared by a detection means on the basis of the generated correlation storing image data in a detecting means 20, and the image data being identical or similar and taken by the image taking means 10 are detected.
