Hidden autofocus
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.
