Abstract: Provided is a clock signal generation circuit. The clock signal generation circuit includes a control word generation circuit, an initial clock generation circuit and a spread spectrum clock generation circuit, wherein the control word generation circuit is connected to the initial clock generation circuit and the spread spectrum clock generation circuit; the initial clock generation circuit is further connected to the spread spectrum clock generation circuit.

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.

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.

Abstract: The present invention provides interactive glasses including a frame, a lens, and a positioning unit, a processing unit and a display unit all fixed to the frame. The positioning unit is used for obtaining location information of current location of the interactive glasses; the processing unit is used for obtaining a relative location relation between the current location and a target location and the information of a route from the current location to the target location according to the location information of the current location and the target location; and the display unit is used for displaying image information of the route from the current location to the target location. Accordingly, the present invention further provides a navigation system. The interactive glasses can provide route from the current location to the target location for users to enable users to reach the target location quickly.

Abstract: The present invention provides a head up display device and a vehicle. The head up display device comprises an arc-shaped screen configured to display information which is to be displayed and projected onto the screen, and to reflect displayed information to human eyes. The head up display device further comprises a transparent film provided on the screen, and the transparent film is configured to change a direction of a light ray reflected by the screen, such that ghosting is prevented from occurring in the displayed information which is reflected into the human eyes.
