PURPOSE:To execute an image processing scarcely influenced by an external light and a surface reflection, and to exactly execute a recognition/decision processing. CONSTITUTION:An image pickup angle of the same processing object 1 by video cameras 3, 4 is varied, images of plural processing objects 1 whose image pickup angles are different from each other are converted to electric signal by the video camera 3, respectively, misalignment of the processing object 1 in plural electric signals from its video camera 3 is corrected, and thereafter, an addition processing is executed. As a result, by image data of plural processing objects 1 whose image pickup angles by the video camera 3 are different from each other, the influence by an external light and a surface reflected light can be softened. Accordingly, even in the case that the processing object 1 has the specular surface or the surface being similar to the specular surface, and the processing object is influenced greatly by an external light and a surface reflected light from other part than a camera and an illuminating system, the processing object can be inspected or recognized exactly. |
