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