Abstract
A method of capturing a video of a scene depending on the speed of motion in the scene, includes capturing a video of the scene; determining the relative speed of motion within a first region of the video of the scene with respect to the speed of motion within a second region of the video of the scene; and causing a capture rate of the first region of the video of the scene to be greater than a capture rate of the second region of the video of the scene, or causing an exposure time of the first region to be less than exposure time of the second region.
Claims10
A method of capturing a video of a scene depending on the speed of motion in the scene, comprising:
- using an image capture device having a plurality of image capture pixels to capture a frame of a video of the scene;
- a region-determining step of determining during capture those pixels of the frame of the video of the scene that constitute a first region which contains a higher speed of motion in the scene than a second region of the frame of the video of the scene;
- a speed-determining step of determining the relative speed of the motion in the first region with respect to the motion in the second region;
- and
- causing the capture rate of the pixels of the first region to be greater than the capture rate of the pixels of the second region, or causing an exposure time of the first region to be less than an exposure time of the second region.
The method of claim 3, wherein the predetermined relative speed would cause greater than two pixels of motion blur per video frame in the first region when applying the capture rate of the second region.
