摘要： Described are a system, apparatus, and method to capture a stereoscopic image pair using an imaging device with a single imaging sensor. Particularly, discussed are systems and methods for capturing a first and second image through an image sensor, determining a vertical and horizontal disparity between the two images, and applying corrections for geometric distortion, vertical disparity, and convergence between the two images. Some embodiments contemplate displaying a directional indicator before the second image of the stereoscopic image pair is captured. By displaying a directional indicator, a more optimal position for the second image of the stereoscopic image pair may be found, resulting in a higher quality stereoscopic image pair.

摘要： A method for adjusting parameters in a video capture device using motion information is disclosed. Motion information that indicates motion of a video capture device is determined. The motion information is compared to an upper bound and a lower bound. An aggressiveness level that indicates a change in a white balance gain for the video capture device is determined based on the comparison. A new white balance gain for the video capture device is determined based on the aggressiveness level. An exposure convergence holding time is adjusted based on the motion information. An exposure step size is increased based on the motion information. A brightness level of the video capture device is adjusted based on the convergence step size.
