Description

technical field [0001] The present invention relates to a signal charge coupled device (CCD) sensing device, and in particular to a signal charge coupled device sensing device capable of accelerating scanning speed. Background technique [0002] Generally speaking, a scanner uses a CCD sensing device placed in an optical machine to perform photoelectric conversion. Such as figure 1 As shown, what is shown is a schematic diagram of a conventional CCD sensing device 102 . The CCD sensing device 102 mainly includes a photo sensor group 106 and a CCD shift register 110 . The light sensing element can be a photodiode. After the exposure time of the photo-sensing device is completed, the signal charge generated by the photo-sensing device will be transferred to the CCD shift register 110 . The CCD shift register 110 can be a two phases (two phases) CCD shift register 110 . The control circuit 104 is used to sequentially store the signal charge sh...
