Abstract
Disclosed are digital imaging devices that embody a method or algorithm for transitioning from a displayable focus process to a high speed focus process which can be displayed, and wherein the transition is accomplished in a seamless fashion. In addition, the digital imaging devices may embody a method for quickly verifying the focus quality of the image. If the focus quality is acceptable, the device indicates that focus is good and avoids a long auto-focus time.
