摘要:
Methods and systems for adjusting a video imaging system that includes an auto-focus mechanism wherein an input from a user of the video imaging system invokes an auto-focus procedure. Responsive to the input, the auto-focus mechanism is scanned over a range of focal distance from a first setting to a second setting indicated by the input. A sequence of images using the video imaging system is captured while scanning the auto-focus mechanism over the range. The images in the sequence are processed so as to compute a measure of focal quality with respect to each of the images. The measure of the focal quality is analyzed so as to select an optimal focal distance, and the auto-focus mechanism is set to the selected focal distance.
