Abstract:
1. An image inspection apparatus, comprising: an image pickup device for acquiring a multi-valued image in an inspection object region; a first threshold setting device for setting as a first threshold a maximum luminance value to be detected in a detection object image; a labeling processing device for performing labeling processing for extracting a plurality of pixels having luminance values larger than the first threshold from the multi-valued image acquired by the image pickup device, to specify blobs of the pixels based upon connectedness of the luminance values of the extracted plurality of pixels; a second threshold setting device for setting a second threshold larger than the first threshold with respect to the blobs of the pixels which are specified by the labeling processing device; and a deletion device for deleting the blob of the pixels which is made up solely of luminance values smaller than the second threshold set by the second threshold setting device.
