Patent number: 9639736Abstract: An image processing apparatus displays an object adopted and an object not adopted by an adoption/non-adoption process in a distinguishable manner. A user designates an object whose adoption/non-adoption result is desired to be reversed among the objects displayed by the image processing apparatus. The image processing apparatus changes an allowable range stored in a storage part so that the adoption/non-adoption result of the designated object is reversed. That is, the user views the adoption/non-adoption result of the objects to change the allowable range of a parameter so that the adoption/non-adoption result becomes proper. This makes the allowable range of the parameter for use in the adoption/non-adoption process proper with ease.Type: GrantFiled: October 29, 2013Date of Patent: May 2, 2017Assignee: SCREEN Holdings Co., Ltd.Inventors: Hiroki Fujimoto, Jiro Tsumura
