Embodiment Construction

[0037] Reference will now be made in detail to embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The exemplary embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0038] figure 1 and figure 2 is a block diagram illustrating an image processing apparatus 100 according to an exemplary embodiment of the present general inventive concept.

[0039] The image processing device 100 is embodied as a host device such as a computer, which receives an RGB scan image from an image capture device 100a such as a scanner, a digital camera, etc., and performs color calibration for performing color conversion to match output characteristics. adapt. In this way, the image processing apparatus 100 can perform color calibration by executing an application program such as a scanner driver, Pho...

Abstract

An image processing method and an image processing apparatus to calibrate a scan image include selecting any one of a plurality of colors having different gray reproduction characteristics, and calibrating the scan image based on a color table corresponding to the selected color among a plurality of color tables.

Description

technical field [0001] The present general inventive concept relates to an image processing apparatus and an image processing method for calibrating scanned images according to user preferences. Background technique [0002] Generally, an RGB scanned image input by a scanner, digital camera, etc. undergoes color calibration for converting colors to suit the characteristics of the output device. [0003] For example, an image processing device such as a computer can perform color calibration on a scanned image having RGB data based on a color table or a look-up table (LUT) based on a standard chart used for color calibration. Generated from CIELab data obtained from color measurements. [0004] Such image processing apparatuses generally store a single color table, and perform color calibration for each input scanned image based on the stored single color table. [0005] In this way, the calibrated scanned image always provides the same color reproduction characteristics re...
