Abstract: Method and systems for autofocus triggering focusing are disclosed herein. In one example, a system may include a lens, a memory component configured to store lens parameters of the lens and regions of focus corresponding to the lens parameters, and a processor coupled to the memory and the lens. The processor may be configured to focus the lens on a target object at a first instance of time, receive information indicative of distances from an imaging device to the target object over a period of time, obtain lens parameters of the lens, and determine a region of focus, and trigger the lens to re-focus on the target object if the distance to the target object indicates the target object is outside of the region of focus and the distance to the target object is unchanged for a designated time period.

Abstract: Exemplary embodiments are directed to dual camera autofocusing in digital cameras with error detection. An auxiliary lens and image sensor shares a housing with a main lens and image sensor which together act as a range finder to determine the distance to a scene. Scene distance is used in combination with contrast-detection autofocus to achieve maximum sharpness in the image. Errors in distance determination may be found and corrected using a comparison of data collected from the auxiliary lens and main lens.

Abstract: Systems and methods of triggering an event based on meeting a certain depth criteria in an image. One innovation of a method includes a identifying at least one object in a field of view of an imaging device, the imaging device configured to capture at least one image of the field of view, determining a threshold depth level, measuring a depth of the at least one object within the field of view with respect to the imaging device, comparing the measured depth of the at least one object to the threshold depth level, and capturing an image of the object when the depth of the object within the field of view exceeds the threshold depth level.

Abstract: Described herein are methods and devices that employ a dual shutter button feature associated with an image capture device to recommend a capture mode to a user based on one or more parameters analyzed by the image capture system. As described, providing a primary shutter button and a secondary shutter button enables the user to capture in both a standard capture mode by using the primary shutter button and in an alternate mode by using a secondary shutter button.

Abstract: Systems and methods for synchronizing frame captures for cameras with different fields of capture are described. An example device includes a first camera and second camera. The first camera includes a first camera sensor and a first rolling shutter. The first camera is configured to prevent scanning pixels from a first row to a row n of the first camera sensor and configured to begin sequentially scanning pixels of the row n of the first camera sensor. The second camera includes a second camera sensor and a second rolling shutter. The second camera is configured to begin sequentially scanning pixels of a first row of the second camera sensor concurrently with beginning to sequentially scan pixels of the row n of the first camera sensor. The first row of the second camera sensor corresponds to a row within a predefined number of rows after the first camera sensor's row n.

Abstract: Aspects of the present disclosure relate to systems and methods for temporal alignment of image frames. An example device may include a processor coupled to a memory. The processor may be configured to receive a first stream of image frames from a first camera for an imaging application being executed by the device and receive a second stream of image frames from a second camera for the imaging application being executed by the device. The processor also may be configured to, for a first image frame of the first stream, associate the first image frame with an at least one image frame of the second stream using a type of association. The type of association may be based on the imaging application. The processor further may be configured to provide the associated first image frame and the at least one image frame of the second stream for processing in executing the imaging application.

Abstract: Method and systems for autofocus triggering focusing are disclosed herein. In one example, a system may include a lens, a memory component configured to store lens parameters of the lens and regions of focus corresponding to the lens parameters, and a processor coupled to the memory and the lens. The processor may be configured to focus the lens on a target object at a first instance of time, receive information indicative of distances from an imaging device to the target object over a period of time, obtain lens parameters of the lens, and determine a region of focus, and trigger the lens to re-focus on the target object if the distance to the target object indicates the target object is outside of the region of focus and the distance to the target object is unchanged for a designated time period.

Abstract: Systems, methods, and devices for power optimization in imaging devices having dual cameras are contained herein. In one aspect, a method for power optimization for a dual camera imaging device is disclosed. The method includes determining a zoom factor selection, determining whether the zoom factor selection falls within a first zoom factor range, a second zoom factor range, or a third zoom factor range, and sending a series of frames of an image captured by a first sensor or a series of frames of an image captured by a second sensor or both to a camera application based on the determined zoom factor section.
