  • Publication number: 20200159175
    Abstract: A sensor unit outputs a real sensor signal corresponding to a measured physical quantity. A controller controls a control target device in an environmental domain on the basis of the real sensor signal. The controller (a) performs a simulation of a specific phenomenon in the environmental domain under a simulation condition, and virtually measures the specific physical quantity on the basis of a simulation result and thereby generates a virtual sensor signal; (b) changes the simulation condition on the basis of the real sensor signal and the virtual sensor signal; and (c) generates a control signal for the control target device on the basis of the simulation condition and/or the simulation result. The simulation, the generation of the virtual sensor signal, and the change of the simulation condition are iteratively performed until a sensor error between the real sensor signal and the virtual sensor signal is converged.

  • Publication number: 20200126510
    Abstract: A display system with high display quality in which display unevenness is reduced is provided. The display system includes a processing unit and a display portion. The processing unit generates second image data by using first image data. The display portion displays an image on the basis of the second image data. The processing unit includes three layers. The first image data is supplied to the first layer. The first image data contains a plurality of pieces of data. The plurality of pieces of data each correspond to any one of the plurality of pixels. The first layer generates first arithmetic data by making the number of data corresponding to one pixel larger than the number of the first image data by using the first image data. The second layer generates second arithmetic data by multiplying the first arithmetic data by a weight coefficient.

  • Publication number: 20200082641
    Abstract: A three-dimensional representation is generated corresponding to real photograph images obtained from a photographing subject by plural cameras. Error images are generated between the real photograph images and virtual photograph images obtained by a three-dimensional representation virtual observation unit. A correction amount is generated of the three-dimensional representation so as to correspond to the error images. The three-dimensional representation is corrected in accordance with the correction amount. In the three-dimensional representation virtual observation unit, a rendering process is performed for the three-dimensional representation and thereby the virtual photograph images are generated so as to be obtained by photographing the three-dimensional representation using virtual cameras corresponding to the cameras. The three-dimensional representation includes plural divisional surfaces arranged in a three-dimensional space.
