1. A method for compensating an image produced by an emissive display system having pixels, each pixel having a light-emitting device, the method comprising:

  • repeatedly adjusting an input provided to a pixel until a comparison value substantially equals a predefined value, the comparison value generated from comparing a reference signal with an integrated pixel current value generated from integrating a pixel current output from the pixel for a pixel integration time; and

    updating calibration data to compensate a programming of the pixel with use of a final value of the adjusted input provided to the pixel.
