CAMERA FOCUSING RELATED METHODS AND APPARATUS

摘要

Methods and apparatus that facilitate or implement focus control in a camera and/or can be used to set the camera focus distance, e.g., the distance between the camera and an object which will appear in focus when the objects picture is taken by the camera. A depth map is generated for an image area, e.g., an area corresponding to an image which is captured by the camera. Based on said depth map, in various exemplary embodiments, a visual indication of which portions of an image captured by the camera device are in focus is generated. A user may indicate a change in the desired focus distance by touching a portion of the screen corresponding to an object at the desired focus distance or by varying a slider or other focus distance control.
