摘要： An information processing device inspects a target image that contains an image of an inspection target. The information processing device includes a pre-processor, a first calculator, a second calculator, and a determiner. The pre-processor is configured to perform pre-processing for comparing the target image with a reference image or a plurality of reference images. The first calculator is configured to define, in the target image, a region of interest (ROI) and surrounding regions that are adjacent to the ROI, and calculate a feature value of the ROI. The second calculator is configured to calculate an outlier from comparison with feature values of images corresponding to the ROI and the surrounding regions in the reference images. The outlier numerically indicates singularity of an image at the ROI. The determiner is configured to provide, based on the outlier, an indicator to be used for the inspection.

摘要： An image processing apparatus includes a light source configured to emit light onto a glass; an image-capturing unit configured to capture light from an image-capturing region including reflection light of the emitted light from the glass; an object detection filter used to detect an object attached to the glass, light from a portion of the image-capturing region entering the object detection filter; an exposure control unit configured to determine a first exposure amount used in image capturing for a first region where the object detection filter does not exist and a second exposure amount used in image capturing for a second region where the object detection filter exists; and an image analysis unit configured to analyze a captured image obtained by the image-capturing unit. The image-capturing unit switches an exposure amount used in an image-capturing process for the image-capturing region between the first exposure amount and the second exposure amount.

摘要： An object identifying apparatus is disclosed, including: an imaging part, and an object identification processing part. The imaging part receives two polarized lights having a different polarization direction included in light reflected from the object existing in the image pickup area and captures two polarization images. The object identification processing part conducts an identification process for identifying the object existing at a place corresponding to each of multiple process areas in the image pickup area by using the two polarization images captured by the imaging part.
