A pixel circuit uses two storage transistors to store two image signal samples, which include a reference signal produced by background noise of the pixel circuit and a signal produced by optical exposure of a photodetector and the background noise of the pixel circuit. An imaging integrated circuit uses a pixel circuit array, which may contain a number of such pixel circuits, and a charge acquisition circuit configured to read out image information obtained by the pixel circuit array. The charge acquisition circuit uses a first amplifier and a serially connected differential integrator that includes a second amplifier, a first differential integrator section and a second differential integrator section for the read out. A method for image information acquisition involves obtaining image information using the pixel circuit array and reading out the image information obtained by the pixel circuit array using the charge acquisition circuit.
