Abstract: An optical system for projecting an image having x and y axes onto a image plane is provided. The system includes an SLM device spaced from the image plane, the SLM device having a plurality of pixels operable to project pixels of the image onto the image plane and positioned such that the individual pixels of the projected image are oriented at substantially 45 degrees relative to the x and y axes of the image. The system further includes an optic element disposed between the SLM device and the image plane and a linear displacement device operatively connected to and operable to selectively displace at least one of the SLM device and the optic element. A method for projecting an image onto a image plane is also provided.

Abstract: An image data control unit for an SLM-based photofinishing system. The control unit is typically used with a photofinishing system in which the SLM provides an exposure region that is smaller than the image to be printed or otherwise produced. Thus, the output image is in motion relative to the SLM, such as by moving the photographic medium under the SLM. To meet system throughput requirements, such systems use an exposure algorithm that exposes each line of the output image with multiple rows of the SLM. The control unit implements the exposure algorithm by reformatting source image data and loading the SLM with SLM settings. It synchronizes these functions to the motion of the photographic medium upon with the image is printed.

Abstract: A machine and method for providing human voice sounding numbers includes storing in digital form segments of leading digit utterance, segments of trailing digit utterances, group pausing utterances and digit pair utterances. A data string of segments is read out of storage and concatenated.
