Image inspecting apparatus and image inspecting program |
摘要 |
Image inspecting apparatus compares first image data created as data representing a reference-image acting as an inspecting reference with second image data created as data representing an inspection-image acting as a target to automatically extract a difference point between first and second image data, and includes a storage means for the reference- and inspection-image, an image processing means for establishing correspondences between part of stored reference-image as first image data with part of stored target image as second image data at a pixel level to perform an image matching processing of them, a difference detecting means for comparing image-matched first and second image data to detect a difference between first and second image data, image producing means for comparing difference with a plurality of threshold values to produce error representing image data at each threshold value, and inspecting process using produced error representing image data at each threshold value. |

1. An image inspecting apparatus for comparing first image data created as data representing a reference-image acting as an inspecting reference with second image data created as data representing an inspection-image acting as a target to automatically extract a difference between the first image data and the second image data, comprising:
a storage means for storing the reference-image and the inspection-image; an image processing means for establishing correspondences between at least a part of the stored reference-image as the first image data with at least a part of the stored target image as the second image data at a pixel level to perform an image matching processing of them; a difference detecting means for comparing the image-matched first and second image data to detect a difference between the first and second image data; and an image inspecting means for producing a plurality of image data by comparing the difference with a plurality of threshold values, each of the image data including a plurality of pixels defining a single image, by fluctuating the threshold value at each partial region, to the detected difference to thereby perform an image inspecting process. |
