  • Patent number: 10755672
    Abstract: A playback device is configured to be connected to a display device. The playback device includes a communication component and a controller. The communication component communicates with the display device. The controller acquires setting information indicating a current setting of a brightness range in the display device from the display device via the communication component. While a specific brightness range has not been set in the display device, the controller transmits information related to a setting change to the specific brightness range via the communication component to the display device based on correspondence information indicating a correspondence relationship between the display device and the brightness range that is settable in the display device.

  • Patent number: 10613830
    Abstract: A data processing device according to one aspect of the present invention includes an extractor configured to extract time-series data indicating observed values at points in time in an analysis range from a first point in time to a second point in time, and a first calculator configured to calculate a gradient of a linear function indicating a trend of change in the observed values in the analysis range to minimize an objective function. The objective function indicates a sum of multiplication values at the points in time within the analysis range, the multiplication value is a numerical value obtained by multiplying a square of a difference between a function value of the linear function and the observed value by a weighting coefficient, and the weighting coefficient is a numerical value that increases as an elapsed time from the first point in time to each point in time increases.
