Abstract
A sensing device, including a plurality of sensing pixels arranged in Y rows and M columns, a plurality of readout lines coupled to the sensing pixels, and a plurality of control lines each coupled to a sensing pixel subset, is provided. The Y times N sensing pixels within the sensing pixel subset are arranged in adjacent N columns, where Y, M and N are integers and N is smaller than M. Each of the control lines is configured to control one row of the sensing pixel subset to output signals through corresponding readout lines.
