<p>An exposure system for use in a color video printer which comprises light emitting diode arrays each for generating red, green and blue light signals, a drive circuit for applying drive signals to the light emitting diode arrays, a base roller disposed at the running path of a cycolor film for functioning as a base surface of the cycolor film, and micro lens arrays disposed between the base roller and the light emitting diode arrays for focusing the lights from the light emitting diode arrays on the cycolor film. By use of the light emitting diode arrays as an exposing light source, the whole structure and manufacturing cost of a color video printer can be simple and reduced.</p> |
