IMAGE INSPECTION APPARATUS, IMAGE RECORDING APPARATUS, AND IMAGE INSPECTION METHOD |
摘要 |
In an image inspection apparatus, a first accumulation part acquires a reference accumulated value distribution by accumulating values of pixels in a reference image arranged in an image recording direction. A second accumulation part acquires an inspection accumulated value distribution by accumulating values of pixels in the inspection image arranged in the image recording direction. A sensitivity correction part performs sensitivity correction wherein a plurality of accumulated values other than a local peak in the inspection accumulated value distribution are corrected so as to relatively approach a plurality of corresponding accumulated values in the reference accumulated value distribution, based on a ratio between the inspection accumulated value distribution from which the local peak has been removed and the reference accumulated value distribution. A comparison part subtracts the reference accumulated value distribution from the inspection accumulated value distribution that has undergone the sensitivity correction to detect a defect. |
