Abstract
An image sensing device includes a first test block, a second test block, and a readout block. The first test block includes a plurality of first image sensing pixels structured to convert incident light carrying an image into a first pixel signal indicative of the image, and a first heating element structured to transmit heat to the first image sensing pixels. The second test block includes a plurality of second image sensing pixels that each include a light blocking structure to be shielded from receiving incident light to generate a second pixel signal without being directly exposed to the incident light, and a second heating element structured to transmit heat to the second image sensing pixels. The readout block processes the first pixel signal output from the first test block and the second pixel signal output from the second test block.
