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.

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.

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.

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.
