Image quality learning device, image quality determination device, and image reading device

An image quality learning device (2) learns a determination result of whether a planar object (1) is a good product or a defective product from at least one of the three-dimensional shape and color of the surface of the planar object (1), and is provided with: a surface image input unit (3) to which two-dimensional data, which is image data of the surface of the planar object (1), is input; a determination information input unit (4) for inputting determination information indicating whether the planar object (1) corresponding to the two-dimensional data is a good product or a defective product; and a learning unit (5) that learns, on the basis of the two-dimensional data and the determination information, a region (1R) in which the three-dimensional shape or color of the surface is present in the two-dimensional data, said region (1R) being a basis for the determination information. 本发明的图像好坏学习装置(2)从平面状对象物(1)的表面的立体形状或色彩中的至少一个学习平面状对象物(1)是良品还是不良品的判定结果，包括：表面图像输入部(3)，其输入有作为平面状对象物(1)的表面的图像数据的二维数据；判定信息输入部(4)，其输入有表示与
