Abstract:
In a color correction method, a reference area is selected in a document page, which is rendered to produce image data. The reference area can be a company logo, a letter or character in a line of text, or other graphic object. The reference area need not be a set calibration chart. The image data is used by a projector to display the document page on a screen. Ambient light may cause colors in the displayed document page to be noticeably different from the intended colors specified in the document page. A camera takes a picture of the displayed document page, and a target area is identified in the camera image based on a characteristic of the reference area that was previously selected. Corrected image data is generated based on a color difference between the reference area and the target area. The projector uses the corrected image data to display the document page, this time with colors that are closer to or the same as the intended colors. The cycle may be repeated on the next document page, in which case the reference and target areas may differ from those of the previous cycle.

Claim (Index 1):
A color correction method comprising:\n performing a document page handling process comprising\n processing, by a computer, a document page, the processing comprising\n selecting a reference area in the document page, \n determining characteristics of the reference area, and \n rendering the document page to produce image data; \n \n sending the image data to a projector configured to use the image data to display a projected image of the document page on a screen; and \n performing a color correction process for the projected image, the color correction process comprising:\n receiving, by the computer, a camera image of the screen showing the projected image, \n identifying a target area in the received camera image based on at least one of the characteristics of the reference area, \n generating corrected image data based on a color difference between the reference area and the target area, and \n sending the corrected image data to the projector, the projector configured to use the corrected image data to display a corrected projected image of the document page.
