Publication number: 20230072780Abstract: A device for stabilizing an image-capturing device against trembling and shaking includes a chip, an image sensor, a first connector, and a second connector. The image sensor collects light and converts same into an electrical signal. The first connector is used for receiving the electrical signal. The second connector is used for electrically coupling the first connector and the chip, wherein the second connector transmits the electrical signal to the chip. The stabilizing device is elastically suspended in place and tremors and shakes on the part of the stabilizing device are cancelled as they occur by reverse displacement based on magnetism and as controlled by Hall effect sensors. The chip can output control signal to the second connector, the second connector transmits the control signal to the first connector, the first connector transmits the control signal to the image sensor to control state of the image sensor.Type: ApplicationFiled: November 30, 2021Publication date: March 9, 2023Inventors: HSIANG-CHIEH YU, HO-KAI LIANG, YE-QUANG CHEN
