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: To determine real-world information about objects moving in a scene, the camera capturing the scene is typically calibrated to the scene. Automatic scene calibration can be accomplished using people that are found moving about in the scene. During a calibration period, a video content analysis system processing video frames from a camera can identify blobs that are associated with people. Using an estimated height of a typical person, the video content analysis system can use the location of the person's head and feet to determine a mapping between the person's location in the 2-D video frame and the person's location in the 3-D real world. This mapping can be used to determine a cost for estimated extrinsic parameters for the camera. Using a hierarchical global estimation mechanism, the video content analysis system can determine the estimated extrinsic parameters with the lowest cost.

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: Methods, systems, and devices for techniques for correcting video rolling shutter jello effect for open loop voice-coil motor cameras are described. A device may capture an image using an open loop voice-coil motor camera including a lens barrel assembly, a base mount, and a brake caliper. The base mount associated with the lens barrel assembly may include the brake caliper. The device may determine a vibration frequency parameter associated with a gyroscope sensor exceeds a threshold. Based on the vibration frequency parameter exceeding the threshold, the device may measure an image sharpness parameter associated with the image. In some aspects, the device may configure engagement of the brake caliper with the lens barrel assembly based on the image sharpness parameter.
