Abstract: A voltage regulator and a control method thereof are provided to dynamically adjust an output voltage. The voltage regulator comprises a plurality of switching transistors and a control circuit. The first end of each switching transistor receives a driving voltage, and the second end of each switching transistor is electrically connected to the end which outputs the output voltage. The input end and the feedback end of the control circuit respectively receive a reference voltage and the output voltage. A plurality of output ends of the control circuit are electrically connected to the control ends of the switching transistors respectively. Switching transistors adjust the output voltage. The control circuit compares the output voltage with the reference voltage, and selectively turns the switching transistors on or off according to the comparison between the output voltage and the reference voltage, to control the output voltage to approach the reference voltage.

Abstract: A superimposition device of virtual guiding indication and reality image includes at least an image capturing device, a processor, a graphic processing unit (GPU), and a display device. The image capturing device captures reality image including instant scene. The processor receives the reality image and obtains height variation information. The GPU performs image correction processing on the reality image to obtain corrected image, generates updated transformation matrix according to the height variation information, and performs inverse perspective projection transformation by using the updated transformation matrix to generate bird's-eye view image of the corrected image and superimposes virtual guiding indication on the bird's-eye view image and performs perspective projection transformation on the bird's-eye view image to transform the bird's-eye view image into three-dimensional (3D) navigation image which includes the guiding indication. The display device displays the 3D navigation image which superimposes the virtual guiding indication into the reality image.
