A circuit device includes an image processing circuit that receives target image data by adding effective image data to known image data, executes image processing on the target image data, and outputs processed effective image data corresponding to a processed effective image and processed known image data corresponding to a processed known image. The processed known image data has a CRC expected value calculated in advance. A CRC calculation circuit obtains a CRC value based on the processed known image data. A determination circuit determines correctness of the image processing by comparing the CRC value with the CRC expected value of the processed known image data. The processed effective image is located in an effective image region that is displayed on a screen. The processed known image is located in a non-display region that is not displayed on the screen.

Circuit device, electronic apparatus, and image processing method

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.

Only the display device stores content files and a management device stores file management information. The content files are managed using the file management information. Because the management device does not store the actual content files, the security policy of an organization is not violated even if the management device is located outside the organization. Furthermore, because the display device stores the content files, the user desire to keep content files locally at hand is satisfied. Furthermore, because file management information consisting of small amounts of data is exchanged between the display system and the management device, the communication environment of the system does not need to be suitable to large data transmissions. Furthermore, because the management device stores the file management information, the storage capacity required by the management device is small.
