Abstract

Dual still image and video mode features are provided for a digital camera whereby the digital camera and an associated computer system support the concurrent capture of still images and video streaming operations. Capture and retrieval of a still image during video streaming operations of a digital camera tethered to a computer system includes pausing video streaming operations, capturing a still image by the digital camera, transferring the still image from the digital camera to the computer system, and resuming video streaming operations. Transfer of the captured still image is performed by camera device driver and bus interface software executing on the computer system. In one embodiment the digital camera is tethered to the computer system by a Universal Serial Bus (USB) and the camera device driver and bus interface software control access and usage of the USB.
