Linear image sensing device with image matching function
In a linear image sensing device with image matching function, a linear sensors array senses a finger, which is moving over it, to obtain fragment image analog signals, which are amplified, by a programmable gain amplifier, into amplified signals. An analog-to-digital converter sequentially converts the amplified signals into digital image signals. An image matching module sequentially receives and processes adjacent two of the digital image signals, and outputs continuous non-overlapped fragment images through an input/output interface. A control logic controls operations and communications of the above-mentioned components. A terminal system receives the non-overlapped fragment images and assembles the non-overlapped fragment images into a complete fingerprint image in a manner of stacking the images side by side.
