| 20090009817 | SCANNING APPARATUS AND WHITE CALIBRATION METHOD THEREOF - A scanning apparatus includes a lookup table generating unit to generate a multidimensional lookup table to convert input signals into standard signals, a minimum value computing unit to scan a white reference and compute minimum RGB values therefrom, a calibration region determining unit to establish a minimum size region in the lookup table that contains a background (BG) point where the computed minimum RGB values coincide, and a white point of the lookup table, and a calibrating unit to calibrate data values only in the established region to white values. Optimum color representation is provided, because only the white region is established and calibrated without influencing other color regions. | 01-08-2009 |
| 20090015852 | IMAGE FORMING APPARATUS AND COLOR TABLE GENERATING METHOD AND COLOR DOCUMENT PRINTING METHOD THEREOF - An image forming apparatus, and a color table generating method and color document printing method of the image forming apparatus. The image forming apparatus includes a color matching unit to match colors of a color document containing one or more images formed with a preset number of colors with colors available in the image forming apparatus, and a color table generator to generate a color table using the matched colors. Therefore, it is possible to reduce the color change caused by a difference in the characteristics between a printer and a scanner. | 01-15-2009 |
| 20100033737 | IMAGE REVISING METHOD, IMAGE FORMING APPARATUS AND METHOD FOR REVISING IMAGE SPREADING - An image revising method, an image forming apparatus, and a method for revising image spreading are provided. The image revising method includes regulating a black color level in a black area of an input image; adjusting a color level of at least one other color excluding the black color in the black area; and revising the image by applying the regulated black color level and the adjusted color level of the at least one other color. Thus, in copying a document, the black color with the enhanced legibility can be serviced. | 02-11-2010 |
| 20100177365 | IMAGE FORMING APPARATUS AND IMAGE QUALITY CALIBRATION METHOD THEREOF - An image forming apparatus and an image quality calibration method in the image forming apparatus, the image forming apparatus including a printing unit to print a calibration chart in one mode selected from a plurality of resolution modes, a scanning unit to scan the printed calibration chart, and a calibrating unit to calibrate an image using color values of the scanned calibration chart according to the plurality of resolution modes. | 07-15-2010 |
| 20100182619 | COLOR COMPENSATION APPARATUS AND METHOD, IMAGE FORMING APPARATUS, AND COMPUTER READABLE RECORDING MEDIUM - A color compensation apparatus, a color compensation method, an image forming apparatus, and a computer readable recording medium are provided. The color compensation apparatus includes a color scheme analyzing unit to classify an input image into one or more objects and to compute average color values for each of the classified one or more objects, a storage unit to store a color table proposed for color compensation, and a color compensating unit to compensate the average color values computed for each of the classified one or more objects using colors of the stored color table which match the computed average color values. | 07-22-2010 |
| 20100201704 | Color management method and apparatus thereof - Disclosed are a color management method, an apparatus thereof and a color management computer program for executing the method that enable a user to conveniently and easily select and/or change colors desired by the user in diverse ways. The color management method includes displaying a color scheme list that is a list of color schemes for providing a standard for converting the colors that constitute an image, and if a selection manipulation of one among the color schemes that constitute the displayed color scheme list is input, storing the color scheme selected by the selection manipulation. | 08-12-2010 |
| 20110055695 | Apparatus and method for creating preview image of object - Apparatus and method for creating a preview image of an object is provided. The apparatus includes an object type detecting unit for detecting an object to be previewed for determining whether the type of the object is text, graphics, and image, a color matching unit for converting a color signal of the detected object into an image forming color signal by using a color profile corresponding to the detected object according to the detection result of the object type detecting unit, and a preview image creating unit for creating and displaying a preview image for the object converted into the image forming color signal. Therefore, because the preview image is displayed on a monitor according to the type of object (text, graphics, or image), a user can predict the image forming result more accurately. Further, because the colors of objects can be adjusted, a printout with desired color characteristics can be obtained. | 03-03-2011 |
| 20110299100 | PRINT CONTROLLING TERMINAL AND COLOR CORRECTION METHOD - A color correction method includes displaying an expected print image of a test image of the image forming apparatus on a monitor, outputting the test image to the image forming apparatus, performing color matching between the output test image and an expected print image on the monitor, changing an ICC profile of the monitor according to the performed color matching, and generating a print data using the changed ICC profile. Also a print controlling terminal which performs the color correction method. | 12-08-2011 |
