  • LED luminance control circuit, LED luminance control method, and LED luminance control program
    Patent number: 10973100
    Abstract: Provided is an ambient temperature estimating device, ambient temperature estimating method, program, and system that are able to realize both high robustness and high ambient temperature estimation accuracy. An ambient temperature estimating device includes a neural network, a temperature acquisition unit configured to acquire one or more temperature values inside the ambient temperature estimating device, and a neural network calculator configured to estimate an ambient temperature around the ambient temperature estimating device using the neural network. Input values inputted to the neural network by the neural network calculator include the temperature values acquired by the temperature acquisition unit and a heat source control value for controlling a heat source inside the ambient temperature estimating device.
