An image processing device includes an image acquirer for acquiring an image, a depth of field calculator for calculating an estimate representing a depth of field of an image based on collateral information of the image, an image divider for dividing the image into evaluation regions, and a blur evaluator for detecting a blur in each of the evaluation regions divided by the image divider, performing blur evaluation for calculating evaluation values for evaluating degrees of an out-of-focus blur or a camera/subject movement-caused blur, and calculating an evaluation value of the image from the evaluation values of the evaluation regions based on the estimated depth of field.
