Abstract: One or more depth sensors are configured to acquire one or more depth measurements associated with at least one object. One or more orientation sensors are configured to determine orientation information of an imaging device based on orientation information of an optical device of the imaging device. An object distance between the imaging device and one of the at least one object is estimated based on the one or more depth measurements and the orientation information of the imaging device. The optical device is moved from a first position to a second position according to the object distance and focal information of the optical device, and is moved from the second position to a third position according to an autofocus operation.

Abstract: A method for adjusting a storage bitrate of a data buffer with a buffer size includes: storing data at a selected storage bitrate into the data buffer; writing the stored data from the data buffer into a storage device attached to the data buffer with a predetermined writing speed; monitoring a data amount of the stored data in the data buffer; monitoring a trend of change in the data amount; determining whether the data amount has reached a first ascending threshold, the first ascending threshold being below the buffer size of the data buffer; and in response to the data amount reaching the first ascending threshold and the trend of change in the data amount being an ascending change, reducing the storage bitrate in the data buffer.

Abstract: A system for automatic focusing with a lens and methods for making and use the same are provided. When performing a focusing operation, a controller calculates a focus measure value for each lens position of a plurality of lens positions. The focus measure values are calculated based on each of the window evaluation values and a respective weight for image focusing windows within a set of image focusing windows. The controller then compares the calculated focus measure values of the plurality of lens positions in order to select an optimal lens position. The set of image focusing windows can be selected based on one or more sets of image focusing window selection rules derived from statistical data. In addition, the respective weights for image focusing windows can also be calculated based on the statistical data.

Abstract: A method for moving an optical device of an imaging device includes one or more depth sensors acquiring one or more depth measurements within a predefined spatial coordinate system. Each of the one or more depth measurements indicates a distance from the imaging device to an object within the predefined spatial coordinate system. The method further includes one or more orientation sensors determining orientation information of the imaging device within the predefined spatial coordinate system, estimating an object distance between the imaging device and the object based on the one or more depth measurements and the orientation information, and moving the optical device from a first position to a second position according to the object distance and a focal length of the optical device.

Abstract: A system for high dynamic range (HDR) imaging and methods for making and using same is disclosed. An HDR module in a camera initializes a set of lookup tables (LUTs) in YUV color space based on exposure configurations of a set of images taken as HDR imaging. The HDR module calculates weights of luminance Y components of the set of images in YUV color space. Based on the calculated weights, the HDR module blends the Y component of the set of images to generate blended Y components. The HDR module combines the blended Y components with corresponding UV components to generate a single image in YUV space. Thereby, the HDR module advantageously combines a set of images into a blended HDR image with only blending the Y component of the set of images.
