Abstract
A sensing device is provided. The sensing device includes a plurality of pixel groups and a readout circuit. The pixel groups are arranged on a plurality of rows and a plurality of columns to form a pixel array. The pixel groups include a first pixel group and a second pixel group which are arranged on the different rows and the same column. The readout circuit is coupled to the pixel groups. When the first pixel group is triggered to perform a readout operation to generate a first sensing signal, the second pixel group performs a coupling operation to generate a reference signal. The readout circuit performs a subtraction operation based on the first sensing signal and the reference signal to generate a first readout data corresponding to the readout operation of the first pixel group.
