Embodiment Construction

[0014] figure 1 It is a flowchart of a method for automatically controlling camera movement in response to a user script. At process block 100, a camera is provided for taking still or video images. The camera is configured to communicate with a camera controller, which can be placed outside the camera to control camera movement and other features on the camera, such as flash, zoom, image size, shutter speed, images per second, ACG, etc. In process block 110, the camera controller automatically controls the movement of the camera in response to at least one user-generated script. Such movement can be done by stepping motors or other means. The camera controller can help the camera maintain focus on the subject during image capture even when the subject is moving. In one example, the user can use the camera to manually select a subject and focus on the subject. Control can then be passed to the camera controller to continue tracking the subject itself. Or, using a predefined...

Abstract

The present application provides increased flexibility and control to a user by providing a camera and camera controller system that is responsive to a user-defined script. The user-defined script can allow a user to choose a subject and have the camera follow the subject automatically. In one embodiment, a camera is provided for taking still or video images. Movement of the camera is automatically controlled using a camera controller coupled to the camera. A user script is provided that describes a desired tracking of an object. The camera controller is responsive to the script for controlling the camera in order to track the object.

Description

Technical field [0001] The present invention relates to the use of a camera to track images, and more particularly, to a system that can control the tracking using a script generated by a user. Background technique [0002] Automatic camera and camera tracking are known. For example, various devices and systems have been proposed for automatically tracking the position of movable objects. Certain systems, such as the system disclosed in US Patent No. 7,450,835, include a suspension or tripod worn by the user to communicate with the camera to aid tracking. Other systems use built-in software to perform primary tracking. However, all such systems are notoriously difficult to train and calibrate. In addition, users have limited control over the tracking process. Summary of the invention [0003] This application provides users with increased flexibility and control by providing cameras and camera controller systems that respond to user-defined scripts. The user-defined script ma...
