  • Patent number: 12260483
    Abstract: Described herein are techniques for learning neural reflectance shaders from images. A set of one or more machine learning models can be trained to optimize an illumination latent code and a set of reflectance latent codes for an object within a set of input images. A shader can then be generated based on a machine learning model of the one or more machine learning models. The shader is configured to sample the illumination latent code and the set of reflectance latent codes for the object. A 3D representation of the object can be rendered using the generated shader.

  • Patent number: 12254828
    Abstract: A method for controlling dynamic change of a screen refresh rate and an electronic device are provided. In a scenario of dynamic change of the refresh rate, a refresh rate switching instruction may be sent immediately through an added refresh rate setting interface (displaySetFps) within a current ith frame period before a current Vsync periodicity ends. After receiving the refresh rate switching instruction, a DDIC drives a display screen to switch a screen refresh rate, and then the DDIC returns a new TE signal. After receiving the new TE signal, SurfaceFlinger starts a new Vsync periodicity corresponding to a switched screen refresh rate. In an embodiment of this application, a switching speed at which the screen refresh rate is switched may be increased by adding a new path. For example, it may be ensured that each switching of the screen refresh rate is completed within one frame.
