Latest Patents
Demarinis holds a patent for an "Automatic color correction for a white-light printer." This invention describes a method and apparatus that compensates for color and brightness variations in a white-light printer. The technology allows the printer to automatically adjust the exposure of a photosensitive medium to optimize the printed image. By generating compensation factors, the printer can individually correct for primary colors within an image. This is achieved by monitoring chromatic transmission through color filters used during exposure. The method involves setting the video output at maximum while varying and measuring brightness in foot-Lamberts. The recorded Luma that produces 'white' is fixed to ensure proper representation of white, black, and gray tones. This procedure is repeated for each primary color, effectively compensating for variations due to different CRTs and their warm-up states.
