Abstract:
A method for scanning comprising:exposing a first linear array of photodetector elements to light for a first exposure time to acquire first, second, third and fourth accumulated charges corresponding to charges of a first, a second, a third, and a fourth group of the photodetector elements, respectively; transferring the first, the second, the third and the fourth accumulated charges to first, second, third, and fourth stages, respectively, of a charge shift register; exposing the first linear array to light for a second exposure time to acquire fifth, sixth, seventh and eighth accumulated charges corresponding to charges of the first, the second, the third and the fourth group, respectively; and transferring the fifth, the sixth, the seventh and the eighth accumulated charges to fifth, sixth, seventh, and eighth stages, respectively, of the charge shift register to interleave the first and second accumulated charges with the seventh and eighth accumulated charges.
