  • Apparatus for creating in-line index prints
    Patent number: 6292253
    Abstract: An in-line index printing system includes a sensor that determines the average density value of a photographic frame, a programmable light source and a video camera. The average density value calculated by the sensor is used to set the current levels supplied to a set of red, green, and blue LEDs to produce light that compensates for the exposure and color characteristics of the photographic frame. The film is illuminated by the light produced by the programmable light source and the video camera captures an image of a frame on the film. The image is digitized, and stored in a memory of a computer where it can be manipulated, if desired to enhance the color. The images from the frames can be printed on a color laser printer, a CRT printer, or transmitted over a computer network, such as the Internet.
