Abstract
A method for banding suppression due to vibration in an imager utilizing a light emitting diode (LED) array is disclosed. By characterizing the LED array and knowing the amplitude and frequency of the signal due to vibration which causes the banding, the LEDs' driving currents are modulated in reverse direction corresponding to the banding signal to suppress the banding.
