1. A method for focusing a camera, the method comprising:
- repeatedly alternating a focus position of an optical element between an original focus position and a plurality of other focus positions while a new focus position is being determined;
displaying an image when the focus position of an optical element is the original focus position;
displaying no images at other focus positions which have not been determined to be a best focus position; and
displaying an image at one of the other focus positions which has best determined to be the best focus position.

Abstract
In a method and system for focusing a camera focus can be repeatedly alternated between an original focus position and a plurality of other focus positions. An image can be displayed when the focus position is the original focus position. The image can be suppressed at other focus positions when the images are out of focus. The image can be displayed at one of the other focus position when the image is in focus. In this manner, the display of annoying and distracting unfocused images is mitigated.

14. An autofocus mechanism for a camera, the autofocus mechanism comprising:
-
an imager; an optical element for focusing an image upon the imager; an actuator for moving the optical element; a position controller for controlling movement of the actuator; an autofocus circuit for determining when an image is in focus; a display device for displaying an in focus image; wherein the imager, the optical element, the actuator, the position controller, and the autofocus circuit cooperate to repeatedly alternate focus between an original position and a plurality of other positions; wherein the autofocus circuit facilitates displaying an image on the display device when the optical element is at the original position; wherein the autofocus circuit facilitates not displaying an image on the display device when the optical element is at other positions and the image is out of focus; and wherein the autofocus circuit facilitates displaying an image on the display device when the optical element is in a new position and the image is in focus. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A method for varying a parameter of a camera, the method comprising:
-
repeatedly alternating the parameter between an original value and a plurality of other values while a new value for the parameter is to being determined; displaying an image when the parameter has the original value; displaying no images when the parameter has other values which have not been determined to be a best value; and displaying an image when the parameter has a value which has best determined to be the best value. - View Dependent Claims (23)
