  • Publication number: 20220236784
    Abstract: A method for switching a power mode of a computer device is adapted to a computer accessory. The method comprises setting a power management mode of the computer device to be awakened when connected to the external power; connecting the computer accessory to a host connector of the computer device to establish a power connection and a communication connection through a host signal pin set of the host connector; through the power connection and the communication connection, detecting and determining the power mode of the computer device; and executing one of following steps upon receiving the switch signal: when the power mode is the normal operation state, transmitting a communication signal; when the power mode is the Suspend-To-RAM state, transmitting a wake up signal; and when the power mode is the Suspend-To-Disk state or the shutdown state, temporarily cutting off the external power and then restoring the external power.

  • Patent number: 9686461
    Abstract: The present invention illustrates an automatic focusing method. Firstly, through multiple cameras of an image capturing device, a scene is captured, such that multiple images generated corresponding to the cameras are obtained. Then, multiple depth maps are generated according to the images. Next, according to the resolutions of single one or multiple objects in the depth maps, the depth information of the single one or multiple objects in the depth maps can be selected to generate a merged depth map. Then, a target focus distance of the single one object or target focus distances of multiple objects are calculated according to the merged depth map. Next, an actual focus distance of the multi-lenses module associated with the cameras is adjusted according to the target focus distance of the single one object or one of the multiple objects.

  • Patent number: 9681043
    Abstract: The disclosure relates to a multi-camera imaging system, and a compensation method for image reconstruction. The main components of the multi-camera imaging system are an image capturing module having a multi-lens module and a multi-sensor module, and a distance adjustment unit automatically adjusting the distance between the multi-lens and multi-sensor modules. Note that the distance adjustment unit conducts compensation performed on the change of the system's focal length caused by temperature in the system. The multi-camera imaging system further includes a position-sensing module which is used to sense a displacement or change of the distance made by the distance adjustment unit. A set of image reconstruction parameters corresponding to the displacement or the change of distance is then provided.

  • Patent number: 8077411
    Abstract: A lens displacement mechanism using shaped memory alloy (SMA) applied to an auto-focusing lens module is disclosed. The lens displacement mechanism comprising at least one SMA wire. Two opposite ends of the SMA wire are fixed and a longitudinal mid-point of an intermediate movable portion between the two opposite ends is tightened and is fixed on a corresponding hook disposed on an outer edge of the lens so that the intermediate movable portion is tightened between the two opposite ends. When the SMA wire is heated, the intermediate movable portion contracts to pull the hook of the lens for driving the lens to move and slide along with an optical axis so as to achieve auto-focus control. The present lens displacement mechanism is simple in structure and reflow process. Therefore, the present displacement mechanism is suitable to be used in portable camera or mobile phone or PDA, which needs to be small and have easily mass production by SMT.
