Document Type and Number:
Japanese Patent JP6939929
Kind Code:
B2
Abstract:
[Object] A circuit device, an electronic apparatus, and an error detection method capable of accurately detecting an error that a user is likely to erroneously recognize are provided.[Solution] A circuit device 100 includes an image acquisition circuit 130 for acquiring a display image and an error detection circuit 150 for performing error detection on the display image. The error detection circuit 150 calculates a histogram of pixel values of the display image, performs a correlation operation using the histogram, calculates an index indicating a degree of dissimilarity between a foreground image that is an image of a given region in the display image and a background image that corresponds to a background of the foreground image in the display image based on a result of correlation operation, and performs the error detection based on the index.
