Abstract: Described is a system having a digital camera and a docking unit which permits the docking unit to receive images over a channel and direct them to a viewable display in the digital camera.

Abstract: An Internet-based video feed management system controls, manages, and efficiently administers the commercial distribution of live video feeds from on-site video cameras as well as other sources of video feeds to production companies at other locations. The system employs a network of local video-propagation servers located in different localities for receiving the video feeds from the different source locations, and a master authorization server for receiving and granting requests via Internet from requesting parties for access to any of the video feeds transmitted to the video-propagation servers. The master server issues an access code to the requesting party and establishing a unique publishing point for the requested video feed from the video-propagation server handling the feed. The on-site video cameras can supply live video feeds to the requesting parties, or the video feeds can be transmitted to a video-propagation server for storage and later re-transmission.

Abstract: A remote-controlled camera-picture broadcast system is provided, which decreases the cost of hardware and network for the use of a lot of unspecified users. This system is comprised of a camera apparatus, a camera controller, a camera server connected to the camera controller through a first network, and clients connected to the camera server through a second network. Each of the clients transmits an operation demand for the camera apparatus to the camera server through the second network according to an input of a user. The camera server receives the operation demand from the client into which the input of the user is applied, and transmits an operation command corresponding to the operation demand to the camera controller through the first network. The camera controller controls the camera apparatus according to the operation command from the camera server so that the camera apparatus acquires a picture and produces a video signal of the picture.

Abstract: When an image read start command is received from a PC, an image reading unit first sequentially reads an image of an original. An output signal of the image reading unit is processed by an analog signal processing circuit, an A/D converter, and an image processing circuit and is supplied to a transfer control circuit. When an instruction from the PC indicates a direct transfer mode, the transfer control circuit outputs the image data from the image processing circuit as it is to an interface. When the instruction from the PC indicates a temporary storage mode, the transfer control unit temporarily stores the image data into a storage medium of an auxiliary storage device. When there is a reading request from the PC, the transfer control circuit reads out the image data which is stored into the auxiliary storage device and transfers it to the PC through the interface.

Abstract: A digital camera system includes a digital image sensor, a memory coupled to the digital image sensor via a data bus, a microcontroller having control signal output ports and a data I/O port, and a bi-directional tri-state buffer coupled to the data I/O port and the data bus for passing data therebetween. At least one of the control signal output ports is coupled to each of the digital image sensor, memory and tri-state buffer. The microcontroller issues control signals over it's control signal output ports to control access to the data bus by establishing only one of a plurality of possible data transfer paths at any given point in time.
