Claim 0:
1. A method for controlling an autoexposure (AE) function of a camera to a gray level setting, said method comprising:
(a) establishing a critical exposure time of an image sensing device of the camera, wherein said critical exposure time of the image sensing device of the camera is an exposure time at which a first sensed gray level of the image sensing device of the camera is disposed at a target gray level according to the gray level setting and the first sensed gray level is disposed in a trend of decreasing sensed gray level values;
(b) exposing the image sensing device of the camera to light to obtain a second sensed gray level of the image sensing device of the camera; and
(c) comparing said second sensed gray level at said critical exposure time to said target gray level, if said second sensed gray level is disposed at least at said target gray level, limiting the exposure of the image sensing device of the camera to said critical exposure time.
