Abstract: A system may include a first pixel array arranged in a first direction and a second direction, and a first shift register coupled to the first pixel array. An output signal of the first shift register may be configured to activate one or more pixels of the first pixel array. The activated pixels may form a first macro reading block, wherein the first shift register may be configured to receive a clock signal to move the first macro reading block in the first direction or the second direction.

Abstract: In some embodiments, an imaging device includes a pixel array. At least one of the pixels includes a photodiode that can generate charges, and a select transistor that receives the charges in its bulk. When the select transistor is selected, a pixel current through it may depend on a number of the received charges, thus evidencing how much light it detected. A reset transistor may reset the voltage of the bulk.
