Abstract:
A solid-state image sensing device comprising:a plurality of image pick-up pixels respectively including bolometers varying the resistivity thereof depending upon the magnitude of an electromagnetic power incident thereon, and connected to a first constant voltage source;a first signal output node for outputting an output data signal containing a noise component due to a pattern of said plurality of image pick-up pixels and representative of said resistivity of a selected image pick-up pixel sequentially selected from said plurality of image pick-up pixels;a second signal output node for outputting a reference signal representative of the magnitude of said noise component of said selected image pick-up pixel;a selector associated with said plurality of image pick-up pixels, and sequentially connecting said first signal output node through the bolometer of said selected image pick-up pixel to said first constant voltage source for producing said output data signal; anda plurality of reference pixels located in the vicinity of said plurality of image pick-up pixels so as to produce said reference signal.
