Abstract
An image auto-calibration method for an image capture device having an image sensor is provided. The method includes the steps of receiving an image matrix; transforming the image matrix into an image signal via the image sensor; generating n first sampling pulses and n second sampling pulses in response to the image signal, wherein one of the first sampling pulses and one of the second sampling pulses constitute a sampling pulse set; calculating an eigenvalue of the image signal according to each of the sampling pulse sets; and outputting an image according to the sampling pulse set with the largest eigenvalue.
