Abstract
A circuit apparatus includes an image acquisition circuit, an error detection circuit, and a search circuit. The error detection circuit determines an indicator representing the degree of dissimilarity between a foreground image and a background image out of a display image based on the result of correlation operation and performs error detection on the display image based on the indicator. The search circuit searches the display image for the display position of the foreground image based on the reference image, which serves as a reference for the foreground image. The error detection circuit performs the error detection based on the display position searched for by the search circuit.
