Abstract
A method of image sensor apparatus includes: providing pixel array having pixel units arranged in M rows and N columns; providing N parallel column readout circuits each being arranged for reading out pixel data of one corresponding column; disposing a horizontal shift register in row direction coupled to the N parallel column readout circuits, to receive a pulse signal and a clock signal, sequentially shift a phase of the pulse signal according to the clock signal, and scan a corresponding column according to the shifted phase of the pulse signal; and using a column select circuit having N latches to receive a power down digital control signal transmitted from a microcontroller wherein the power down digital control signal is used to disable at least one column readout circuit to enable and select a portion of the set of N parallel column readout circuits.
