  • Patent number: 7295234
    Abstract: A dc level control method for holding a dc level of a clamp portion in an electric signal to be a prescribed value is disclosed, wherein the method comprises the steps of: comparing a dc level of a sampling interval in said electric signal with a predetermined reference value to obtain a difference between said dc level and said reference value using an A/D converting section for dc level comparison which has a lower bit resolution than an A/D converting section for digital signal processing of said electric signal; and feeding back a clamp signal to said electric signal so that said obtained difference between said dc level and said reference value substantially becomes zero. This method is suitable for applying to a signal processing system for a solid state imaging apparatus.

  • Patent number: 7295756
    Abstract: By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal.

  • Patent number: 7295543
    Abstract: A power source of a LAN terminal at a home such as home server is turned on from the outside the home via the Internet. A home gateway apparatus receives such a start request by proxy and transmits a start instruction packet to corresponding equipment on the home LAN. Although there is a case where the protocols of an external network and the home LAN are different from each other, the home gateway apparatus performs a protocol conversion process for assimilating discrepancy between the protocols. Moreover, on the home LAN, the start instruction packet to the corresponding equipment maybe issued by utilizing a magic packet technique.

  • Patent number: 7295994
    Abstract: When content data are distributed from an information center via a predetermined communication line to a terminal apparatus loaded with a recording medium recorded with its identifier and prepaid information, the information center manages the usable remaining amount of money in the recording medium loaded in the terminal apparatus and updates this usable remaining amount of money every time content data are distributed. Further, if the usable remaining amount of money is smaller than the price of the content data distributed from the information center, the information center instructs the terminal apparatus to load another recording medium having a usable remaining amount of money sufficient to cover the content data to be distributed. Still further, a remaining recordable capacity of a recording medium loaded in the terminal apparatus is transmitted to the information center, and the information center compares the remaining recordable capacity with the size of the data content to be distributed.

  • Patent number: 7296055
    Abstract: Disclosed is an information providing system in which the information providing apparatus first receives a connection request from the first information processing apparatus. Upon receipt of the connection request, a check is made to see whether the information providing apparatus is providing any image data or sound data to the second information processing apparatus. If the information providing apparatus is judged to be providing any image data or sound data to the second information processing apparatus, then information related to a chat program is transmitted to the first and the second information processing apparatus. After transmitting the connection request to the information providing apparatus, the first information processing apparatus receives the information related to the chat program from the information providing apparatus. Upon reception of the information, the first information processing apparatus executes a process based on the received information related to the chat program.

  • Patent number: 7295238
    Abstract: An image-signal processing apparatus (1) designed to process the signals output from a CCD image sensor (10) that reads pixel data for one screen, line by line, divides the pixel data into a plurality of channels and outputs the pixel data thus divided. The image-signal processing apparatus (1) detects and corrects the black level of each pixel data item that the image sensor (10) has output for one channel. The image-signal processing apparatus (1) detects and corrects the gain difference between channels, which pertain to the pixel data items output from the image sensor (10). Hence, the apparatus (1) can correct the black level of each pixel data item and the gain difference between channels with high accuracy, when used in combination with an image sensor that divides pixel data into a plurality of channels.
