Abstract:
An image sensor, which comprises: an image sensing matrix, comprising at least one image sensing unit, 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.
