ABSTRACT:
A scanner system digitizes 35 mm transparencies or negatives, and converts the image to a format compatible with popular microcomputer systems. This scanner system can accommodate various formats, and has variable zoom, pan and window size. Color separation is accomplished by an illumination arrangement causing rapid sequential generation of red, green and blue components. A low wattage light source is used, and color balance is achieved by adjusting the respective exposure times of the three primary colors. The system has internal calibration to achieve repeatable color balance. The system implements a wide variety of color coding schemes ranging in resolution from 1 to 24 bits. An adaptive process compresses the data in order to optimize the color selection process. The illumination optics are anamorphotic for high efficiency. Mechanical and electrical interfaces are compatible with a conventional 51/4" floppy disk drive standard.
