摘要： Apparatus and methods for conditional display of a stereoscopic image pair on a display device are disclosed. Particularly, some implementations include receiving a first image and a second image, determining a vertical disparity between the first image and the second images, and displaying a stereoscopic image pair if the vertical disparity is below a threshold. Some implementations provide for correcting the vertical disparity by generating at least one corrected image, and generating the stereoscopic image pair based on the corrected image. Some implementations may evaluate the quality of the stereoscopic image pair, and display either a two dimensional image or the stereoscopic image pair based on the evaluation.

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.
