An image forming apparatus and a color correction method, and a host apparatus to correct the color of an output image using the color correction method. The image forming apparatus can include a table correction unit to correct the color conversion table based on monitor information, and a color conversion unit to convert the input image into the output image using the corrected color conversion table. Accordingly, the color of a displayed image can match that of a print output regardless of the status of the display apparatus.

Image forming apparatus and color correcting method thereof, and host apparatus to correct the color of an output image using the same

Disclosed is a method for correcting color in a portable image projector in consideration of an effect of a background color when the portable image projector projects images. The method corrects the effect of the background color to be projected, using color constancy technique, and thereby represents high-quality image which can be projected on a white screen. The method includes the steps of determining if a background color exists on a projection screen using a portable camera, converting the size of a mask image in order to connect a spatial position of an original image and an image photographed by a camera, correcting brightness of the mask image in order to correct non-homogeneity of the brightness of the projected image due to the distribution of different brightness values of the background color, and correcting the background color in order to correct color distortion of the image projected in different colors on the background color. The background color correction step includes the sub-steps of initializing chromaticity of the white screen in advance, and correcting chromaticity using a technique of color constancy of human eyesight.

Method and apparatus for adjusting image colors of image projector

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.

Print controlling terminal and color correction method generating print data using monitor profile changed based on comparison of printed test image to expected print image displayed on monitor
