  • 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.
