SYSTEMS AND METHODS FOR REMOTE CAMERA CONTROL

摘要

A camera capable of capturing still images and video and included in a portable media device can be controlled remotely using an accessory. The accessory can register with the PMD to automatically receive notifications whenever there is a change in the camera state. The camera states can include mode, operation status, and configuration settings. The accessory can send instructions to a camera application that interfaces with the camera to control the camera. The accessory can remotely activate the camera, change camera mode, and send instructions to operate the camera. The accessory and the PMD can concurrently control the camera. The PMD can send the captured still images and recorded video to the accessory for preview and receive instructions from the accessory on disposition of the still images and the video.
