Figure Pixel Selection Principle Y readout shift register X shift register Next to the pixel array there are two Y shift registers, and one X shift register with the column amplifiers. The shift registers act as pointers to a certain row or column. The Y readout shift register accesses the row line of pixels that is currently readout. The X shift register selects a particular pixel of this row. The second Y shift register is used to point at the row of pixels that is reset. The delay between both Y row pointers determines the integration time -thus realizing the electronic shutter. A clock and a synchronization pulse control the shift registers.
