Transparency Image Scanning Patents (Class 358/506)
  • Patent number: 5363217
    Abstract: An image transferring device which consists of a light source transmitter for transmitting a collimated light beam, a light reflector positioned to intercept the collimated light beam, a motor for rotating the light reflector, a film positioned at the focal point of the light reflected from the mirror; an imaging lens mounted so as to rotate with the mirror and to focus the light beam onto film, and a motor and lead screw for advancing the mirror in a direction along its axis of rotation so that the light beam traverses an image portion of the film.

  • Patent number: 5329383
    Abstract: An improved method of producing positive photographic prints in hybrid photofinishing system employing a digital image printer to produce an intermediate negative image on a non-photographic medium wherein digital data used to print the negative includes code values simulating an orange mask effect in the negative. The improvement in the method involves a reduction in the orange mask values in the digital data so as to reduce the D-max values required for digitally printing the intermediate negative thereby reducing print cost and throughput time in the process. In a further improvement, the printer code values for pixels corresponding to full white in the final image are forced to values that print as black in the negative thereby eliminating the orange mask effect for these pixels and rendering improved rendition of full white areas in the final image print.
