Abstract
A multi-resolution charge-coupled device (CCD) sensing apparatus is provided. The multi-resolution CCD sensing apparatus includes a photo sensor set, a shift gate, and several CCD shift registers. The shift gate includes several switches for receiving the charge signal from the photo sensor set and the switches. The switches output the charge signals to the corresponding CCD components with respect to different resolutions for the acquisition of the scanning image with different resolutions. It can achieve the economy of size, low cost by using the multi-resolution CCD sensing apparatus according to the invention and therefore speeds up scanning at low resolution.
