  • Publication number: 20180207968
    Abstract: An electronic device is configured to acquire image data containing a test pattern including first and second patterns intersecting with each other. Pixels corresponding to the test pattern are determined by comparing brightness of each pixel with a threshold value, and widths of an overlapped image of the first and second patterns in an orthogonal direction at a plurality of different positions in the reference direction are calculated. Intersecting positions of the first pattern and the second pattern in the test pattern is detected based on a distribution of widths at the plurality of different positions. The test pattern has a model pattern having a set width in the orthogonal direction separate from the first and second patterns. The pixels corresponding to the test pattern are determined based on a threshold value, and widths at the plurality of positions of the overlapped image in the reference direction are calculated.
