Claim Text:
1. An image sensor, comprising: an image sensing matrix, comprising a plurality of image sensing units, for generating at least one image sensing signal according to a sensed image; an amplifier, for amplifying the image sensing signal to be an amplified image sensing signal according to at least one amplifying parameter; an operational circuit, for computing at least part of brightness of the sensed image sensed by the image sensing unit according to the amplified image sensing signal to generate at least one operational brightness signal; and a control unit, for adjusting the amplifying parameter, such that brightness information generated based on brightness values, which corresponds to the operational brightness signal, falls in a predetermined range; wherein the image sensing matrix utilizes a plurality of the image sensing units in an image sensing window to sense the image, where the control unit controls a sum of the brightness values corresponding to at least part of the operational brightness signal to fall in the predetermined range, wherein the operational brightness signal corresponds to one row or one column of the image sensing units in the image sensing window.
