Avoiding image artifacts caused by camera vibration
First Claim
1. A method, comprising timing the taking of at least one photographic exposure by a camera, the camera mounted with a camera mount on a vibrating object causing the camera to vibrate, in relation to the vibration so as to substantially avoid image degradation caused by the vibration, wherein a predetermined number of trial video frames is taken, wherein each trial video frame is compared with a reference frame, wherein the trial frame that most closely correlates with the reference frame is selected as the requested video frame, and wherein timing the taking further comprises delaying the taking of the exposure until the camera position deviates from a reference position by less than an amount configured to depend on characteristics of the camera, characteristics of the camera mount, the expected vibration, and a desired performance.

Abstract
Methods and apparatus are disclosed for avoiding image artifacts caused by camera vibration. The taking of one or more photographic exposures is timed in relation to the vibration, so as to avoid motion blur, video jitter, or both. The vibration may be characterized by motion sensors, or by analysis of image data.

- 1. A method, comprising timing the taking of at least one photographic exposure by a camera, the camera mounted with a camera mount on a vibrating object causing the camera to vibrate, in relation to the vibration so as to substantially avoid image degradation caused by the vibration, wherein a predetermined number of trial video frames is taken, wherein each trial video frame is compared with a reference frame, wherein the trial frame that most closely correlates with the reference frame is selected as the requested video frame, and wherein timing the taking further comprises delaying the taking of the exposure until the camera position deviates from a reference position by less than an amount configured to depend on characteristics of the camera, characteristics of the camera mount, the expected vibration, and a desired performance.
- 15. A camera, comprising plural gyroscopes and logic, the camera mounted with a camera mount on a vibrating object causing the camera to undergo a vibrating motion, each gyroscope configured to produce voltages proportional to respective rates at which each gyroscope and the vibrating object are rotating for characterize rotations about more than one axis, the logic configured to time the taking of at least one photographic exposure by the camera in relation to the vibration so as to substantially avoid image degradation caused by the vibrating motion, wherein a predetermined number of trial video frames is taken, wherein each trial video frame is compared with a reference frame, wherein the trial frame that most closely correlates with the reference frame is selected as the requested video frame, and wherein the logic further comprises delaying the taking of the exposure until the camera position deviates from a reference position by less than an amount configured to depend on characteristics of the camera, characteristics of the camera mount, the expected vibration, and a desired performance.

23. A camera, comprising:
-
means for characterizing camera motion resulting from the camera being mounted on a vibrating object; means for timing the taking of at least one photographic exposure in relation to the vibration so as to substantially avoid image artifacts caused by the vibration; means for taking a predetermined number of trial video frames; means for comparing each trial video frame with a reference frame; means for selecting the trial frame that most closely correlates with the reference frame as the requested video frame; and means for delaying in the taking of the exposure until the camera position deviates from a reference position by less than an amount configured to depend on characteristics of the camera, characteristics of the camera mount, the expected vibration, and a desired performance.
