Abstract:
An image diagnostic device comprising circuitry configured to output a diagnostic chart for image defect detection, read a predetermined reading range of the diagnostic chart, output a read image based on reading of the predetermined reading range, detect an image defect in the diagnostic chart based on the read image, and determine whether the image defect is at an end of the read image. In response to a determination that the image defect is at the end of the read image, the circuitry controls rereading to read a rereading range of the diagnostic chart different from the predetermined reading range.
