PURPOSE:To execute partial matching by a small number of processings by executing an AND processing of first image data to be aligned and first mask image data, and an OR processing of second mask image data and second image data to be aligned, brought to gradation inversion, and deriving the most matching one part from difference image data between each image data. CONSTITUTION:To an output terminal of an image pickup device 1, an image memory 5 of an image processor 4 is connected through an A/D converter 3, and by first and second image data to be aligned, which are stored, partial matching is executed. In this case, first image data to be aligned is brought to gradation conversion and brightened uniformly by a prescribed value and an AND processing to first mask image data is executed, and also, second mask image data is brought to gradation inversion and an OR processing to second image data to be aligned is executed. Subsequently, from difference image data between each image data derived by a matching recognizing means, the most matching part is derived. In such a way, partial matching can be executed by a small number of processings. |
