Photosensitive self scan array with noise reduction

摘要: A noise reduction scheme for a photosensitive self scan system includes an array of elements producing video signals and first second pluralities switching elements, one element each the being connected to array. line connects plurality input terminal summing device such as differential amplifier amplifier. Shift register means operated by clock pulses is provided control operation sequentially couple apply periodically only pulse through gate drain capacitance amplifier, so produce at output signal substantially free created pulses.
