摘要： An image sensor of a camera system captures an image over an image capture interval of time, and waits a blanking interval of time before capturing an additional image. The captured image is provided to a frame controller, and is buffered until an image signal processor accesses the captured image. The image signal processor processes the accessed image over an image processing interval of time, producing a processed image. The image processing interval of time is selected to be greater than the image capture interval of time, but less than the sum of the image capture interval of time and the blanking interval of time. By reducing the image capture interval of time but maintaining an image processing interval of time, rolling shutter artifacts are beneficially reduced without increasing the processing resources or power required by the image signal processor to process the image.

摘要： Systems and methods are provided that capture and process frames of frame data. An image sensor captures frames of frame data representative of light incident upon the image sensor using a rolling shutter and outputs the frames of frame data. The image sensor captures at least one of the frames over a frame capture interval and then waits over a blanking interval before capturing another frame. A buffer receives and stores the frames output by the image sensor. An image signal processor retrieves the frames from the buffer and processes the frames over successive frame processing intervals to generate a video having a time interval per frame greater than the frame capture interval. At least one of the successive frame processing intervals is greater than the frame capture interval and is less than or equal to a sum of the frame capture interval and the blanking interval.

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.
