Abstract: The present disclosure relates to an eyewear and a control method thereof. The eyewear includes an optic, a camera device and a frame; wherein the optic and the camera device are respectively located on the frame; and the optic is a transparent display screen. The control method of the eyewear includes: detecting a light intensity of ambient light; obtaining a current light intensity of transmitted light generated after the ambient light passes through the optic, based on the light intensity of the ambient light and current light transmittance of the eyewear; adjusting the light transmittance of the optic; starting the camera device to acquire an environment image; performing enhancement processing on the environment image to obtain an enhanced environment image; and controlling the optic to display according to the enhanced environment image.

Abstract: A pair of glasses is provided. The glasses include a first lens, a second lens, a first temple arm that is disposed close to the first lens, and a second temple arm that is disposed close to the second lens. The glasses further include a position adjusting portion that is mounted on the first lens and the second lens. The position adjusting portion is configured to adjust an overlapping area of the first lens and the second lens. The glasses further include a first display screen on a first temple arm. The first temple arm and the second temple arm may be bent in extension directions of the temple arms, so that a tail end of the first temple arm overlaps a tail end of the second temple arm.

Abstract: Provided are a clock signal production circuit, a clock signal production method, and an electronic device, relating to the technical field of communications. In the clock signal production circuit, by digital circuits such as a control word generation circuit, an initial clock generation circuit, and a spread spectrum clock generation circuit, a frequency control word is first generated on the basis of spread spectrum parameters, an initial clock signal of a target duty cycle is then generated on the basis of the frequency control word, and spread spectrum processing is finally performed on the basis of the target duty cycle of the initial clock signal and the frequency control word to obtain a spread spectrum clock signal, i.e., the entire spread spectrum process is executed by the digital circuits. Therefore, it is not necessary to control the electronic device comprising the clock signal production circuit to stop working, i.e., the normal operation of the electronic device is not affected. Moreover, according to the clock signal production circuit, real-time adjustment of spread spectrum parameters (such as spread spectrum depth) that affect a spread spectrum result can be implemented, and the spread spectrum flexibility is relatively high.
