ABSTRACT:
In a photographic film scanner having a film transport drive stepper motor, an illuminant head having a plurality of spectrally separate light source, a light sensor and data collection and transfer circuits, each operationally responsive to a programmed controller. The controller is provided with a common timer and is programmed with a plurality of lookup tables (LUT), each LUT is populated with a sequence of elements defining timing of an operating activity in a respective one of the illuminant head light sources, the stepper motor and the light sensor data transfer circuits. The program operates to use the common timer to step synchronously through the elements of the LUTs to output value states from the elements of each of the LUTs; to control the actuation timing of the respective light sources, stepper motor and data collection and transfer circuits.
