We have just developed a digital printing system in which the traditional negative film is replaced by the LCD. Since the image displayed on the LCD is influenced by the illuminant derived from the three dichroic mirrors (RGB), and gamma adjustment proceeded in the signal processor IC. We put forward a close-loop image adjustment subsystem including some hardware and a set of effective algorithms. The image adjustment is proceeded by detecting the RGB intensity of the image on the LCD through image sensors, and transferring it to the computer, and then setting the relationship between the image in the computer and the data from the image sensor by the algorithms. As a result, we can get the perfect photo image.
