Image feature identification and motion compensation apparatus, systems, and methods
First Claim
1. An apparatus, comprising:
- motion priority logic to estimate a magnitude of relative motion between a scene and an image capture device used to capture the scene, the relative motion occurring during a time period between a time of capturing a first calibration image of the scene and a time of capturing a second calibration image of the scene; and
final image exposure logic to calculate at least one exposure setting associated with the image capture device using the magnitude of relative motion.

Abstract
Apparatus, systems, and methods disclosed herein may estimate the magnitude of relative motion between a scene and an image capture device used to capture the scene. Some embodiments may utilize discrete cosine transform and/or Sobel gradient techniques to identify one or more blocks of pixels in an originating calibration image frame. Matching blocks of pixels may be located in a successive calibration image frame. Motion vectors originating at one calibration frame and terminating at the other calibration frame may be calculated. The magnitude of relative motion derived thereby may be used to adjust image capture parameters associated with the image capture device, including exposure settings.

16. A method, comprising:
-
capturing a first calibration image of a scene at a first time (T1) using an image capture device; capturing a second calibration image of the scene at a second time (T2); estimating a magnitude of relative motion between the scene and the image capture device during a period between the first time and the second time using the first calibration image and the second calibration image; adjusting an exposure setting using the magnitude of relative motion between the scene and the image capture device as estimated; and capturing a final image using the adjusted exposure setting.
