NOISE DETECTING DEVICE, NOISE DETECTING METHOD, AND PROGRAM

摘要

A noise detecting device includes an image acquiring unit and a parallel processing unit. The image acquiring unit acquires an image from a camera that captures the image of a test pattern including a plurality of lines tilted at a specific angle relative to a specific direction. The parallel processing unit sequentially extracts image signals for two lines extending in parallel in the specific direction of the image, the two parallel lines being away from each other by a specific number of lines, and performs in a parallel manner, for each image signals for the two parallel lines, processing for detecting noise generated in the image on the basis of a difference in pixel values calculated from the image signals for the two parallel lines.
