Abstract
An image processing device is adapted to be provided with a photographing device configured to generate image data by photographing a print pattern and to output the image data, vertical synchronization signals, and horizontal synchronization signals. The image processing device includes: a first processor configured to, based on the synchronization signals, determine occurrence of abnormalities of the image data that is input, a memory including two storage areas, and a second processor. The second processor is configured to perform for each frame of the image data an addition process while exchanging a first storage area and a second storage area different from the first storage area of the memory with each other.
