ABSTRACT:
An image scanning method for a scanner that can simultaneously sense image signals corresponding to the three primary colors or a monochromic color, and store the signals in a storage device within one exposition process. The scanning method can further determine a period of the driving signal and a number of rotation steps for the driving motor to calculate the period of the triggering signal for a light-sensitive device. The scanning method according to the invention can therefore reduce the time needed for a scanning process and improve efficiency. Furthermore, the signal-to-noise ratio of a CCD module can be improved, and the requirement for the brightness of the light source is lowered as well.
