  • Patent number: 11936826
    Abstract: An image inspector includes a recording device and circuitry. The reading device is configured to read an image on a recording medium. The circuitry is configured to determine whether the recording medium has a wrinkle and an edge folding based on a plurality of positions on the image on the recording medium read by the reading device satisfying a predetermined relation. The circuitry is configured to determine whether the recording medium has the wrinkle based on the predetermined relation, and then determine whether the recording medium has the edge folding based on the predetermined relation.

  • Patent number: 11800037
    Abstract: An image inspecting device includes an abnormality detector and circuitry. The abnormality detector is configured to detect an abnormality of an inspection object image. The circuitry is configured to set a non-detection area to be excluded from a detection object area within which the abnormality detector detects an image abnormality and set an area including an abnormality detection portion as the non-detection area when a detection result obtained by the abnormality detector satisfies a non-detection condition.
