  • Patent number: 11019255
    Abstract: A method of image processing includes obtaining depth information respectively corresponding to one or more objects in an image frame captured by an imaging system based on spatial configuration of the imaging system, calculating one or more rendering parameters associated with one of the one or more objects in the image frame based on at least the depth information of the one or more objects, and rendering the image frame using the one or more rendering parameters to obtain a processed image frame. The processed image frame includes an in-focus region and an out-of-focus region relative to the one of the one or more objects.

  • Publication number: 20200007746
    Abstract: An imaging system includes one or more sensors configured to detect movement of a movable object carrying an imaging device and one or more processors individually or collectively configured to set one or more parameters of the imaging device such that the imaging device is focused on a target object when the movable object is in a first spatial disposition, detect a movement of the movable object from the first spatial disposition to a second spatial disposition through the one or more sensors, and modify the one or more parameters of the imaging device in response to the detected movement such that the imaging device is focused on the target object when the movable object is in the second spatial disposition.

  • Patent number: 10447912
    Abstract: Systems, methods, and devices for setting camera parameters are provided. In one aspect, a system for imaging a target object using an imaging device carried by a movable object comprises: one or more sensors configured to detect motion information for the movable object; and one or more processors configured to: receive, from the one or more sensors, the motion information for the movable object; determine, based on the motion information, a change in a spatial relationship between the movable object and the target object; and modify one or more parameters of the imaging device based on the determined change in the spatial relationship between the movable object and the target object such that the imaging device is focused on the target object.
