Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of determining whether an area having the same degree of color as a background existing near an end portion of a document is an object or a background.SOLUTION: A first identification unit identifies a rectangular document area whose outer shape represents a rectangular boundary of a document image. A second identification unit identifies a boundary area that is an area formed by connecting a plurality of pixels whose pixel values are within a pixel range set according to a background color and a part of which is in contact with the boundary of the boundary area in the rectangular document area. A first determination unit determines whether a boundary pixel portion constituted by a plurality of pixels in contact with the boundary of the rectangular document area in the boundary area is divided along the boundary of the rectangular document area by consecutively arranging pixels, which has a predetermined number or more, in which pixel values are not included in the pixel range. A second determination unit determines that a boundary area determined that the boundary pixel portion is not divided is a background, and determines that a boundary area determined to be divided is an object.SELECTED DRAWING: Figure 2

Title: Electric heating device
Inventor: IDE AKIHIRO
IPC: H05B3/00
Filed: 2017-03-29
Abstract: To provide an electric heating device capable of preventing a metallic body from being heated at a temperature exceeding a target temperature.SOLUTION: Beginning from the start of electric power supply to a metallic pipe material until a switch timing T1 that is set at a point before the temperature of the metallic pipe material reaches a target temperature, constant current control is performed in such a manner that a current command value Ic may be a highest possible predetermined current value Id. In this way, the metallic pipe material is heated to a certain extent in a short period of time. After the switch timing T1, the current command value Ic is reduced so that the metallic pipe material is heated in such a way that its temperature gradually rises, thereby preventing the temperature of the metallic pipe material from exceeding the target temperature.SELECTED DRAWING: Figure 3
