An image-based acceptance learning device () learns a result of determination as to whether a planar object () is acceptable or defective based on at least one of a three-dimensional shape or a color on a surface of the planar object (). The device () includes a surface image receiver () to receive an inputted two-dimensional data being image data of the surface of the planar object (), a determination information receiver () to receive an inputted determination information indicating the result of determination as to whether the planar object () corresponding to the two-dimensional data is acceptable or defective, and a learner () to learn, based on the two-dimensional data and the determination information, a relevant area (R) including the three-dimensional shape or the color on the surface in the two-dimensional data. The relevant area is a basis for the determination information.
