  • Patent number: 8773590
    Abstract: A video output apparatus includes an attribute information acquisition unit that acquires attribute information of a display apparatus through a communication unit, a determination unit that determines whether to superimpose additional information on a video signal based on the attribute information of the display apparatus acquired by the attribute information acquisition unit, an output unit that superimposes the additional information extracted by an additional information extraction unit on the video signal output from a video decoding unit and outputs the additional information superimposed on the video signal to the communication unit if the determination unit determines to superimpose the additional information on the video signal, and outputs the video signal output from the video decoding unit to the communication unit without superimposing the additional information on the video signal if the determination unit determines not to superimpose the additional information on the video signal.

  • Patent number: 8599713
    Abstract: There is provided a communication apparatus capable of performing HEAC communication with another communication apparatus compliant with HEAC communication, comprising: a receiving unit configured to receive an HEC signal from the other communication apparatus via a transmission path; a detecting unit configured to detect a signal level of the HEC signal received by the receiving unit; a deciding unit configured to decide an amplification factor of an HEC signal to be transmitted based upon the detected signal level in a case where the detected signal level is not within prescribed limits; an amplifying unit configured to amplify the HEC signal to be transmitted at the decided amplification factor; and a transmitting unit configured to transmit an HEAC signal, which includes an ARC signal and the HEC signal to be transmitted amplified by the amplifying unit, to the other communication apparatus via the transmission path.

  • Patent number: 7327386
    Abstract: An image capture apparatus includes an image capture unit, an image processing unit, a memory, and a network interface unit. The image capture unit captures an image. The image processing unit generates an image file including the captured image and additional information and stores the image file in a storage medium. The memory stores the image file read from the storage medium. The network interface unit transmits the image file stored in the memory to an external apparatus via a network. Furthermore, the network interface unit deletes predetermined additional information from the image file before transmitting the image file to the external apparatus, the predetermined additional information including information relating to a user of the image capture apparatus.

  • Patent number: 7304664
    Abstract: A digital camera and a printer are directly connected to each other, and a printing progress situation is displayed on a display unit of the digital camera while an image taken by the digital camera is being printed. Further, when a printing mode is changed to a photographing mode while the printing is being performed, the image being taken is displayed on the entire display unit, and the printing progress situation is superposed and displayed on a predetermined area of the display unit on which the image being taken is displayed.

  • Patent number: 6839835
    Abstract: In a processor system having a CPU, a RAM, and a communication portion for external communication, the operation of the central processing unit is stopped when an IPL operation mode is selected by an operation mode selection switch. An IPL program transferred from the outside through the communication portion is then written to the RAM starting from a predetermined address, and the stoppage of the operation of the CPU is thereafter canceled. The CPU restarting the operation executes the IPL program written to the RAM by first reading the predetermined address to download a system program. Since the IPL program is transferred from the outside, the IPL program to be used can be easily changed.

  • Publication number: 20040247308
    Abstract: An image capture apparatus (e.g., a digital camera, a digital camcorder, or a camera-equipped cell phone) automatically deletes predetermined additional information (e.g., information concerning captured images, a user, etc.) included in a stored image file before transmitting the image file to a destination. This prevents the additional information from being leaked.
