  • Publication number: 20210358150
    Abstract: Systems and methods are described for three-dimensional localization using light-depth images. For example, some of the methods include accessing a light-depth image, wherein the light-depth image includes a non-visible light depth channel representing distances of objects in a scene viewed from an image capture device, and the light-depth image includes one or more visible light channels that are temporally and spatially synchronized with the depth channel; determining a set of features of the scene in a space based on the light-depth image; accessing a map data structure that includes features based on light data and position data for the objects in the space; accessing matching data derived by matching the set of features of the scene to features of the map data structure; determining a location of the image capture device relative to objects in the space based on the matching data.

  • Patent number: 9973722
    Abstract: Systems, devices, and methods of displaying and/or recording multiple pictures in a picture (PIP) on the same display of a digital display device are disclosed. The PIPs can show objects from the main field view of the display device, such as a front camera lens, as well as objects from a different field of view, such as a back camera lens. The PIPs can further track the objects that are being displayed.

  • Patent number: 9716822
    Abstract: Methods and imaging devices are disclosed for determining a first direction to move a lens in an autofocus operation. For example, one method includes capturing a plurality of frames depicting a scene, selecting a portion of at least one frame that corresponds to an object in a displayed frame, and tracking the object in the plurality of frames, where tracking the object provides a reference parameter of the object for each of the plurality of frames. The method may further includes detecting a change in the reference parameter of at least a first frame and a second frame of the plurality of frames, determining a focus direction based on the change in the reference parameter, and initiating a focus operation by moving a lens of the imaging device based on the determined focus direction.

  • Patent number: 9686463
    Abstract: Systems and methods for continuous automatic focus are disclosed. In some aspects, an object to focus on is selected from a field of view of a camera. At least one region of the field of view that includes the object is monitored for change. Regions of the field of view that do not include the object may not be monitored, thus improving efficiency and speed. If a change in the image content of the monitored region(s) occurs, the method may trigger a focus event. If the object moves to different region(s) of the field of view, the method detects the movement and adjusts the regions of the image being monitored to maintain focus on the object. In some aspects, the size of the object is also monitored. If the size of the object changes, a focus event may be triggered, depending on whether the amount of change exceeds predetermined parameters.

  • Patent number: 9628720
    Abstract: An apparatus includes a processor and a memory. The memory stores instructions that when executed by the processor cause the processor to perform operations including receiving a command to perform an image capture of an image including an object. The operations further include determining a first speed threshold based on a first light condition at a first time. The operations further include determining a first speed of the object. The operations further include, in response to determining the first speed of the object exceeds the first speed threshold, determining a second speed threshold based on a second light condition detected at a second time. The operations further include determining a second speed of the object. The operations further include initiating the image capture of the image in response to determining the second speed of the object does not exceed the second speed threshold.

  • Patent number: 9454827
    Abstract: Systems, devices and methods for improved tracking with an electronic device are disclosed. The disclosures employ advanced exposure compensation and/or stabilization techniques. The tracking features may therefore be used in an electronic device to improve tracking performance under dramatically changing lighting conditions and/or when exposed to destabilizing influences, such as jitter. Historical data related to the lighting conditions and/or to the movement of a region of interest containing the tracked object are advantageously employed to improve the tracking system under such conditions.
