置。 In an image processing device that evaluates the degree of dissimilarity between an input image and a reference image and determines whether or not the target image is included in the input image based on the evaluation result, the degree of dissimilarity between the input image and the reference image is evaluated. The evaluation means includes a first means for calculating the magnitude of the difference in brightness at each point between the reference image and the input image, a second means for summing the output of the first means for each small section of the screen, and a second means for summing the output of the first means for each small section of the screen. a third means for determining the magnitude relationship between the output of the means and a given threshold; and means for counting the determination results of the third means obtained for each of the small sections and outputting the counting results as evaluation values. An image processing device characterized by:
