Summary:To provide a circuit device, an electronic apparatus, and an error detection method capable of properly detecting an error that a user is likely to erroneously recognize.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 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 the correlation operation, and performs the error detection based on the index.SELECTED DRAWING: Figure 1 【課題】ユーザーが誤認識するようなエラーを適切に検出することが可能な回路装置、電子機器及びエラー検出方法。【解決手段】回路装置１００は、表示画像を取得する画像取得回路１３０と、表示画像のエラー検出を行うエラー検出回路１５０と、を含む。エラー検出回路１５０は、表示画像の画素値のヒストグラムを求め、ヒストグラムを用いた相関演算を行い、表示画像のうち所与の領域の画像である前景画像と、表示画像のうち前景画像の背景に相当する背景画像との間の非類似度合いを表す指標を相関演算の結果に基づいて求め、その指標に基づいてエラー検出を行う。【選択図】図１
