Device for detecting anomalies in digital images

摘要

A comparison unit compares pixel components of stored image and anticipated image. A controller determines that pixel components of stored image is equal and proportional to the luminance of pixel of anticipated image, when pixel components of stored image are all identical to pixel components of anticipated image. The controller determines that pixel component of stored image does not correspond to luminance of pixel of anticipated image, when pixel components of stored image differs from components of the pixels in the anticipated image.
