Abstract
A hand-supportable digital image capture and processing system comprises: an area-type image formation and detection subsystem having an area-type image detection array; an LED-based illumination subsystem having a LED-based illumination array; an automatic light exposure measurement and illumination control subsystem; an image capturing and buffering subsystem; and an image-processing subsystem. The LED array is automatically driven in a precise manner to globally expose the area-type image detection array with LED-based illumination only when substantially all of its rows of pixels are in a state of integration and have a common integration time, thereby enabling the capture of high quality images independent of the relative motion between the object and the hand-supportable digital image capture and processing system.
