  • Patent number: 10623638
    Abstract: An image-capturing device uses a light reflecting member to redirect an exterior light image toward a lens module in order to focus the light image onto an image-capturing unit. The image-capturing device includes a rotating unit for driving the light-reflecting member to rotate within a limited range in such a manner that the image-capturing device can capture at least two light images of different photo-ing areas and combine them into one single combined image without a need of moving the image-capturing unit and the lens module. When a user takes a panoramic or wide-ranged picture, he/she doesn't need to move the whole image-capturing device, but only needs to stand at the same position, faces the same direction and simply pushes the shutter button, and then the image-capturing device will automatically capture light images of different photo-ing areas and then integrate them into one single panoramic or wide-ranged picture.

  • Patent number: 10613295
    Abstract: The tri-axis close-loop feedback controlling module for electromagnetic lens driving device comprises a 6-pin Hall element. Two pins of the Hall element are coupled to an auto-focus module for providing a current to drive the auto-focus module to conduct auto-focusing operations along the Z-axis; while other four pins of the Hall element are coupled to a control unit. The control unit detects the X-Y axial positions of the auto-focus module relative to an OIS module and generates a control signal which is then sent to the Hall element. Therefore, the Hall element not only can provide its own feedback controlling function according to the Z-axial position of lens, but also can drive the auto-focus module based on the control signal corresponding to the X-Y axial positions of the auto-focus module, so as to achieve the goal of tri-axis close-loop feedback controlling for the electromagnetic lens driving device.
