Problems solved by technology

[0011] The main technical problem to be solved by the present invention is to provide a monochrome image processing system and its method that can perform image removal based on dynamic data. Table, so that the original image can fully and synchronously carry out the image removal processing procedure, which can improve the problem that the previous image removal processing procedure cannot be carried out synchronously; in addition, the lookup table can also be used according to the different copying modes selected by the user, such as: text Mode (text mode), image mode (photo mode) and automatic mode (auto mode), set different mode attribute parameters to generate lookup tables that meet different copy modes for use, and increase image back processing in multiple copy modes Program Application Resilience

Embodiment Construction

[0049] The present invention is a monochrome image processing system and its method capable of performing image background removal according to dynamic data. It is often applied to multi-function machines at present. The basic system block diagram is shown in FIG. 1 .

[0050] First of all, it is about the hardware part. The required original image 10 can be obtained through the image input module 100 (such as a scanner). After obtaining the pixel data of the original image 10, it may be necessary to perform basic image processing through the image pre-processing module 200. Programs, these programs include: pixel linearization (PixelLinearization), gamma correction (Gamma Correction), etc., which are the common parts of the existing system, and the part processed by the image pre-processing module 200 is the main part of the present invention Where the technical characteristics are, as explained below.

[0051] The image / text separation module 300 will sequentially read the r...

Abstract

The method comprise: when making image / text separation, firstly getting the pixel distribution information about a part of image; then generating the lookup table required by executing the program to erase the background of image; synchronously making the background erasing program for overall image.

Description

technical field [0001] The present invention relates to an image processing system and its method, in particular to a monochromatic image processing system and its method capable of image background removal. Background technique [0002] In the copying function of a Multi-Function Peripheral (MFP), usually an image input device such as a scanner is used to obtain an original image and perform many image processing procedures before copying. [0003] The process of obtaining the original image often has inherent interference factors, such as: the source document (source document) is too thin, the source document is used on both sides, the source document itself is dirty, or some acquired interference generated during the process of obtaining the original image Factors make it easy to have smudge noise in the image data of the original image obtained by the scanner. If these smudge noise cannot be effectively removed, it will seriously affect the output quality of the actual i...
