摘要:
A method of scanning an object at a predetermined resolution along the scanning direction with color scanner apparatus having M linear photosensors positioned in parallel, spaced-apart relation and being exposed for a predetermined exposure time, may comprise the steps of calculating an exposure delay time for each of (M-1) slave linear photosensors. Then, at a start scan time, a master linear photosensor is exposed to light from the illuminated scan line for the predetermined exposure time. However, the slave linear photosensors are not necessarily exposed at the start scan time. Instead, the first exposure for each of the slave linear photosensors is delayed for a time equivalent to the exposure delay time calculated for each respective slave linear photosensor.
