Abstract: This image processing device operates by identifying a region that is in a similar image and has a pattern which is the same as a pattern appearing in a section of a reference image, and repeating an operation several times and the section and the region are superposed to generate a reduced-noise fragment, after which the reduced-noise fragments obtained for all of the regions of the reference image are combined to generate a reduced-noise image. When such an operation actually is attempted with an image processing device the regions corresponding to the sections in the reference image cannot be found from the similar image. Therefore, with the present invention the reduced-noise fragments are generated by performing spatial processing on the sections. Thus, reduced-noise fragments can be obtained reliably for all of the regions of the reference image, and noise can be removed from the reference image more reliably.

Abstract: An inspection system includes an image processing unit that suppresses noise of a complex number image on which pixels are represented by a complex number indicating a periodic change in a vibration state of an inspection target. The image processing unit acquires a degree of similarity between a pixel included in a target image region defined in the complex number image and a pixel included in a plurality of reference image regions defined in the complex number image separately from the target image region by comparing complex numbers representing pixels, and executes noise suppression processing of the target image region by using a weight based on the acquired degree of similarity.

Abstract: According to the aspect of the present invention, an image processing device capable of absolutely removing noises in each frame forming a live image can be provided. Specifically, according to the aspect of the present invention, a target block T can be set in the original image It and it is searched out where such target block T is imaged in the superimposition target image Ot−1. According to the aspect of the present invention, a tracking of the subject image is executed per block, so that reliability thereof can be extraordinarily improved compared to the conventional method searching the destination every individual pixel.
