MOTION-BASED CAMERA MODE CONTROL TO REDUCE ROLLING SHUTTER ARTIFACTS

摘要

Cameras may monitor its operation and automatically switch between operation modes thereby to best capture users' experiences. Auxiliary sensor data collected by the one or more sensors and/or captured image data may be analyzed to determine when a camera should switch to a high-motion operation mode. The auxiliary sensor data include motion information of the camera and the content of the captured images include motion information of the captured objects. When a camera or objects captured by the camera are moving rapidly, the camera is switched to operate at the high-motion operation mode to ensure image quality and minimize artifacts to best capture users' experiences. Motion of the camera may be detected or predicted by analyzing the auxiliary sensor data and motion of the captured objects may be detected by analyzing the captured image data thereby to determine whether or not the camera should switch to the high-motion operation mode.

主权项

1. A method for controlling operation of a camera, comprising:
receiving, from one or more sensors of the camera, sensor data; determining a motion of the camera based at least in part on the received sensor data; comparing the motion of the camera to a threshold motion; configuring the camera to operate in a low-motion operation mode responsive to the motion being below the threshold motion; while the camera is operating in the low-motion operation mode, capturing a first image by an image sensor during a first frame capture interval comprising a first percentage of a first frame period; responsive to determining that the motion of the camera exceeds the threshold motion, transitioning the camera to a high-motion operation mode; while the camera is operating in the high-motion operation mode, capturing, by the image sensor, a second image during a second frame capture interval comprising a second percentage of a second frame period, the second frame capture interval shorter than the first frame capture interval and the second percentage of the second frame period shorter than the first percentage of the first frame period.
