Abstract: A control device includes a memory and a processor. The memory is configured to store a time comparison table. The processor is configured to determine whether a displayed image is a still image. When the displayed image is determined to be a still image, the time comparison table is queried for a corresponding still image judgment duration according to an average pixel level and a type of the still image.

Abstract: Disclosed are a three-dimensional imaging method, apparatus and device, and a storage medium. The three-dimensional imaging method may include: acquiring hardware configuration information of an electronic device and a ranging module supported by the electronic device; determining a ranging dot matrix density and a picture material pixel value according to the hardware configuration information of the electronic device; ranging on a plurality of points on an outer surface of a to-be-measured object by utilizing the ranging module according to the ranging dot matrix density, and obtaining depth information of the plurality of points; building a standard three-dimensional coordinate system according to the depth information of at least three points of the plurality of points; photographing the to-be-measured object according to the picture material pixel value and obtaining a plurality of picture materials; and performing three-dimensional imaging processing on the to-be-measured object.

Abstract: A method and circuit for frequency compensation, a storage medium, and an electronic device, the method including: determining speed information of a terminal device relative to a predetermined device, where the speed information includes acceleration information and vector information; converting the speed information into a first acceleration value corresponding to a Global Positioning System (GPS) device; and compensating a frequency of a crystal oscillator in the terminal device based on the first acceleration value and a second acceleration value, where the second acceleration value is an actual acceleration value of the GPS device determined by the terminal device.
