  • Publication number: 20240280628
    Abstract: A measurement method includes determining a first relationship by measuring a reverse recovery charge of a semiconductor element at a plurality of conditions of a measurement device. The measurement device has mutually-different parasitic inductances at the plurality of conditions. The semiconductor element includes a diode component. The first relationship is between the parasitic inductance and a measured value of the reverse recovery charge. The method includes estimating a true value of the reverse recovery charge when the parasitic inductance is zero based on the first relationship.

  • Patent number: 11418767
    Abstract: Transmission of HDR image data is satisfactorily performed between apparatuses. A transmission apparatus (synchronized apparatus) transmits the HDR image data to a reception apparatus (source apparatus) over a transmission path. At that time, the transmission apparatus transmits information on a transmission method for and/or information on gamma correction for the HDR image data to the reception apparatus over the transmission path. The reception apparatus performs processing (decoding processing, gamma correction processing, and the like) on the received HDR image data, based on the information on the transmission method and/or the information on the gamma correction that are received. For example, the transmission apparatus receives from the reception apparatus the pieces of information on the transmission method and/or the gamma correction that the reception apparatus can support, selects the method that the reception apparatus can support, and thus uses the selected method.

  • Patent number: 10999554
    Abstract: HDMI transmission of uncompressed image data, on which dynamic range processing is performed, is performed from an HDMI source device and a display in appropriate luminance is performed in an HDMI sink device. When HDMI input switching is performed, a television receiver 13 transmits transmission request information to an HDMI source device in a destination of the input switching and acquires dynamic range conversion definition information of uncompressed image data at intended timing. Also, when it is possible to acquire the dynamic range conversion definition information of the uncompressed image data, the television receiver 13 minimizes transmission of the dynamic range conversion definition information from a BD recorder 11 by sending reception recognition information back.

  • Patent number: 10638139
    Abstract: A conversion from a dynamic range conversion image into a desired image is performed in a favorable manner. A setting unit sets a plurality of items of knee position information about a conversion from a first dynamic range image into a second dynamic range image. An encoding unit encodes the second dynamic range image to generate encoded data. A determination unit determines priority order of the plurality of items of knee position information. An adding unit adds the plurality of items of knee position information to the encoded data of the second dynamic range image, with the priority order given to the plurality of items of knee position information.

  • Patent number: 10623805
    Abstract: HDR image data are successfully transmitted between devices. High dynamic range image data are sent to an external device. Transmission scheme information and/or gamma correction information for the high dynamic range image data are sent to the external device. The external device can easily understand, for example, what kind of transmission scheme and what kind of gamma correction scheme are used for the sent high dynamic range image data. Therefore, the high dynamic range image data can be successfully transmitted.
