The invention provides a compact-size image-sensing device and an image-sensing element thereof. The compact-size image-sensing device is composed of a plurality of image-sensing elements that are connected to one another and is connected to a signal output terminal bus. Each image-sensing element includes: a photosensitizing unit that is used to sense the light source and convert it into an electrical signal for outputting so as to generate an voltage difference; a reset circuit to charge the photosensitizing unit so that the photosensitizing unit can be reset back to its original voltage before photosensitizing; and a readout circuit, which is to store the electrical signal and read the electrical signal out to a signal output terminal bus. In addition, the reset circuit of a former image-sensing element is connected to the readout circuit of a latter image-sensing element so that every two image-sensing elements can perform reading-out and resetting simultaneously and respectively by using the same signal line. Therefore, the invention can achieve minimizing the chip size as well as lowering the production cost.
