Embodiment 1

[0049] This embodiment provides an image processing method, which can be executed by an image processing device in an image forming device, and can be implemented by means of hardware and / or software.

[0050] The image forming device in this embodiment may be a copier, a scanner, a facsimile machine, or a device that integrates functions such as copying, scanning, and facsimile.

[0051] Figure 4 It is a flow chart of the image processing method provided by Embodiment 1 of the present invention. Such as Figure 4 As shown, the image processing method provided in this embodiment includes:

[0052] Step 101. During the shading correction process, initial correction parameters for shading correction on the correction medium are obtained.

[0053] The shading correction in this step may be implemented in a manner in the prior art, for example, the implementation manner mentioned in the background art herein.

[0054] The correction medium is a correction white strip 118 , wh...

Embodiment 2

[0073] This embodiment optimizes the image processing method on the basis of the foregoing embodiments, and in particular further optimizes the method for obtaining compensation parameters in step 102 .

[0074] Corresponding to step 102, the compensation parameter corresponding to the image reading component may be the first scanning result obtained by performing an actual scanning process on the first imaging medium with a known color value according to the image reading component, and the first imaging medium The difference between the known color values ​​​​is set. This setting process may be performed by an external device, or may be performed by an image forming device.

[0075] If the setting process of compensation parameters is performed by external equipment, the image reading component in the image forming device can perform an actual scanning process on the first imaging medium with a known color value to obtain the first scanning result, and then the first scannin...

Embodiment 3

[0095] This embodiment optimizes the image processing method on the basis of the foregoing embodiments, and in particular further optimizes the method for obtaining compensation parameters in step 102 .

[0096] Corresponding to step 102, obtaining the compensation parameter corresponding to the image reading component, this embodiment provides another specific implementation method:

[0097] The compensation parameter is set according to the difference between the second scanning result obtained by the image reading component and the second imaging medium performing an actual scanning process and the preset correction parameter; the color value of the second imaging medium and the correction medium The same; the preset correction parameters are obtained by performing shading correction on the correction medium. This setting process may be performed by an external device, or may be performed by an image forming device.

[0098] If the setting process of compensation parameter...

Abstract

The present invention provides an image processing method, device, and image forming equipment, wherein the image processing method includes: during the shading correction process, acquiring initial correction parameters for performing shading correction on a correction medium, and the correction medium is pasted on the image forming equipment the first side of the glass plate in the middle; acquire the compensation parameters corresponding to the image reading component; the image reading component is set in the image forming device and is located on the second side of the glass plate in the scanning module; according to the compensation parameters The initial correction parameters are compensated to obtain actual correction parameters; during the actual scanning process, the scanned image is corrected according to the actual correction parameters. The image processing method, device and image forming equipment provided by the invention can reduce the imaging chromatic aberration, and further improve the imaging effect.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an image processing method, device and image forming equipment. Background technique [0002] Image forming equipment includes: printers, copiers, fax machines, scanners, and multi-functional all-in-one machines that integrate printing, copying, faxing, and scanning functions. Their function is to print images or text on imaging media. An image forming device for performing a printing function directly prints images or characters on an imaging medium according to a received print job. However, the image forming equipment used for copying, faxing and scanning firstly scans the imaging medium on which images or texts have been printed, and prints the same image or text on a new imaging medium according to the scanning result. [0003] figure 1 It is a schematic structural diagram of an image forming device in the prior art. Such as figure 1 As shown, the image forming devi...
