The invention discloses a pixel-level focal plane reading circuit and a random window implementation circuit and method thereof, and belongs to the technical field of microelectronics and photoelectronics, and the random window implementation circuit comprises a row selection signal generator, a column selection signal generator and a plurality of pixel control circuits; the random window realization circuit adopted by the invention is simple in structure, can realize the random window of the pixel-level focal plane readout circuit, and can not be used any more after a corresponding row and column selection signal is obtained after configuration is performed once after startup, so that the power consumption and the bit error rate of the circuit can be greatly reduced. Besides, a pixel control circuit is arranged for each pixel of the pixel-level focal plane array, so that unwanted windows are prevented from being selected when multi-window selection output is realized, and the working efficiency of the readin
