Problems solved by technology

[0004] While conventional methods are capable of correcting the overall brightness or saturation characteristics of an imaging device, there are limitations in maintaining gray or color balance
[0005] In addition, since conventional correction methods can only correct brightness or saturation, it is difficult to meet the color characteristics required by users

Abstract

The invention relates to an imaging device and a method of correcting color. An imaging device includes: a storage unit storing a color conversion table; a user interface unit receiving a color correction start command; an imaging unit that prints a color card generated based on the color conversion table if the color correction start command is received, and the color The card has a plurality of CMYK mixed colors in which at least one of brightness and chroma is changed; the scanning unit scans the printed color card; and the modification unit revises the color conversion table using the scanned color card.

Description

technical field [0001] The present general inventive concept relates to an image forming device and a method of correcting color. More particularly, the present general inventive concept relates to an image forming apparatus that corrects colors so as to realize characteristics of user-intended output, and a method of correcting colors. Background technique [0002] The image forming apparatus prints print data generated by a print control terminal device such as a computer onto a recording medium. Examples of image forming devices include copiers, printers, facsimiles, or multifunction peripherals (MFPs) that combine copiers, printers, and facsimiles in a single device. [0003] In order to maintain the original output characteristics, the related art maintains the output characteristics of the imaging device through gamma or halftone correction using a conventional C / M / Y / K gradation chart with only increased saturation. That is, the prior art employs a method of maintain...
