Close focus with GPU

机译:使用GPU密切关注

摘要

Disclosed are systems and methods for focusing a digital camera to capture a scene. It is first detected that a change in a scene requires the digital camera to be focused or refocused. The camera focus is automatically scanned from a closest settable distance to farther distances until a first closest object in the scene is detected. Once the first closest object in the scene is detected, the camera focus is set at the distance of the first closest object and a finer scan is executed. In an embodiment, a dynamic movement threshold is calculated and used to determine that the change in scene requires the digital camera to be focused or refocused.
