no. 1 approach
[0021] In this embodiment, an image forming apparatus with a decolorizing function will be described as an example of an image processing apparatus.
[0022] The image forming apparatus 1 is a multifunctional peripheral (MFP; Multi Function Peripheral) capable of forming a toner image on a sheet and having a function of decolorizing the sheet on which the image is formed. Here, decolorization means making an image formed of a color (not only chromatic, but also achromatic, such as white and black) different from the base color of the sheet to be visually invisible.
[0023] figure 1 It is a control block diagram showing the hardware configuration of the image forming apparatus 1 .
[0024] Image forming apparatus 1 includes detection unit 100 , control unit 110 , storage unit 120 , reading unit 130 , control panel 140 , printer unit 150 , heating unit 160 , transport unit 170 , and communication interface (I / F) unit 180 . Each part of the image forming apparatus 1 is connect...

Abstract
Provided are an image processing device and an image processing method capable of efficiently performing decolorization processing. An image processing device according to an embodiment includes a paper feeding unit, a first transport path, a detection unit, a heating unit, a second transport path, and a control unit. The paper feeding section feeds a sheet. The first conveyance path serves as a conveyance path for sheets fed from the paper feed unit. The detection unit is provided downstream of the paper feeding unit along the first transport path, and detects an image formed on a sheet. The heating unit is provided downstream of the detection unit along the first transport path, and performs decolorization treatment on the sheet by supplying predetermined heat from the first surface side of the sheet. The second conveyance path branches off from a branch point located downstream of the heating section with respect to the first conveyance path, and merges at a merging point located upstream of the heating section. The control unit controls the number of times of the decolorization treatment performed on the sheet and the amount of heat supplied to the sheet in the decolorization treatment based on the detection result of the detection unit.
Description
technical field [0001] Embodiments of the present invention relate to an image processing device and an image processing method having a function of decolorizing an image formed on a sheet by heating. Background technique [0002] In recent years, there are devices that perform a process of erasing an image formed on a sheet by heating (hereinafter referred to as decolorization process). Conventionally, in a configuration in which the decolorization treatment is performed by heating from one side of the sheet, the number of decolorization treatments is changed depending on whether the surface of the sheet to be decolorized is one side or both sides. [0003] However, among them, the time until the decolorization process is completed may increase or the power consumption may increase. Contents of the invention [0004] The problem to be solved by the embodiments of the present invention is to provide an image processing device and an image decolorization method capable of ...
