Claim:
1. An image evaluation device, comprising a processor that causes the device to function as: a reading unit that is configured to read a sample image included in a sample printout recognized as a non-defective printout and that reads an inspection object image included in an inspection object printout obtained by printing an image corresponding to the sample image on a recording medium using a printing device based on image data representing the image; an extraction unit that is configured to extract a line defect including a linear pattern formed in a specific direction from the inspection object image represented by inspection object image data, based on a difference value between sample image data obtained by reading the sample image and the inspection object image data; and an evaluation unit that is configured to evaluate a visibility of the line defect extracted by the extraction unit, wherein an evaluation of the visibility at the evaluation unit includes deriving a level of visibility recognizable by a vision of a person, wherein the evaluation unit is further configured to evaluate the visibility of the line defect using a mask effect-visual model, wherein the evaluation unit is further configured to combine the line defect extracted by the extraction unit with the sample image represented by the sample image data, and evaluates the visibility of the line defect based on a combined image obtained by the combination and on the sample image, using the mask effect-visual model, and wherein the mask effect-visual model comprises a method of modeling human visual characteristics.
