Patent ID: RE43087

Claim:
An image scanner for reading and converting an image of an object into digital image data, the image scanner comprising: a photoelectric sensing device including a plurality of sensing pixels arranged at equal spaces for converting an optical signal from said the object into an electric signal; a shifting device connected to said the photoelectric sensing device for driving said the photoelectric sensing device from a first position to a second position along an X-direction to obtain a first electric signal and a second electric signal, respectively, wherein a distance between said the first and said the second positions is less than a distance between two adjacent sensing pixels, and said the first and said the second electric signals are alternately arranged and converted to form said the digital image data; a mirror set arranged upstream of said the lens device for transmitting said the optical signal from said the object to said the lens device; and a carriage housing mounting therein said carrying the mirror set, said the photoelectric sensing device and said the shifting device, and moved wherein the carriage housing is configured to move along a Y-direction to scan said the object.
