Problems solved by technology

[0005] The applicant once applied for the above-mentioned problem, and applied for a Taiwan patent (the case number is 098139978). However, in the previous application, the pixels need to be increased by 4 times or 9 times, so the resolution is relatively poor, and the calculation is also more time-consuming. The method of the present invention can further improve the previously proposed method

Abstract

The invention discloses a method for reducing the content of black in a digital image. An original digital image is processed by using a computer to achieve the purpose that the content of the black is low or eliminated. The method mainly comprises the steps of: processing every three adjacent pixels as one group and respectively carrying out increment on RGB (Red, Green and Blue).

Description

technical field [0001] The invention relates to a method for reducing black content in a digital image, so that after a printer prints the digital image, the digital image can completely contain or greatly reduce the content of black ink (or carbon powder). Background technique [0002] Commercially available printers will automatically judge the image delivered by the user's computer, and use the method of mixing black ink (toner) to achieve the printing grayscale effect, so as to save the consumption of color ink (toner) and achieve better dark parts Detail effect. However, some applications do not want the printer to print images with black ink (toner), such as using a light pen (also known as OID Pen, OID: Optical Index / Optical Identification, for example, refer to http: / / www.giga.com.tw / english / productpen.htm) reads the printed code for reading voice (mostly very fine two-dimensional barcode) covered on an image. The printed code for reading voice is basically black. ...
