段を備えたことを特徴とする画像処理装置。 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. As a means of evaluating
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 determining the magnitude relationship between the output of the first means and a given threshold; An image processing apparatus comprising means for counting the judgment results of the second means and outputting the counting results as an evaluation value.
