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.

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.
Abstract translation: 本文包含用于具有双相机的成像设备中的功率优化的系统，方法和设备。 一方面，公开了一种用于双摄像机成像装置的功率优化方法。 该方法包括确定缩放因子选择，确定缩放因子选择是否落入第一缩放因子范围，第二缩放因子范围或第三缩放因子范围内，以及发送由第一传感器捕获的图像的一系列帧 或基于所确定的缩放因子部分的由第二传感器或两者捕获的图像的一系列帧到照相机应用。

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: A method of performing an image autofocus operation using multiple cameras includes performing, at an image processor, a first autofocus operation on a first region of interest in a scene captured by a first camera and determining a second region of interest in the scene captured by a second camera. The second region of interest is determined based on the first region of interest. The method further includes performing a second autofocus operation on the second region of interest. The method also includes fusing a first image of the scene captured by the first camera with a second image of the scene captured by the second camera to generate a fused image. The first image is based on the first autofocus operation and the second image is based on the second autofocus operation.

Abstract: Described is a method and apparatus for unattended image capture that can identify subjects or faces within an image captured with an image sensor. The methods and apparatus may then score the image based, at least in part, on scores of detected subjects or faces in the image, scores of facial expressions, a focus score, exposure score, stability score, or audio score. If the score of the image is above a threshold, a snapshot image may be stored to a data store on the imaging device. In some aspects, if the score of the image is below a threshold, one or more audible prompts may be generated indicating that subjects should change positions, smile or remain more still during the image capture process.
Abstract translation: 描述了一种用于无人值守的图像捕捉的方法和装置，其可以识别用图像传感器捕获的图像内的对象或面部。 方法和装置可以至少部分地基于图像中检测到的对象或面部的分数，面部表情的分数，焦点得分，曝光分数，稳定性分数或音频分数来评分图像。 如果图像的分数高于阈值，则快照图像可以被存储到成像装置上的数据存储。 在一些方面，如果图像的分数低于阈值，则可能产生一个或多个可听见的提示，指示受试者在图像捕获过程期间应该改变位置，微笑或保持更多。
