Abstract: Times of receipt of start-of-frame indications associated with frames received from multiple image sensors at a video controller are monitored. Time differences between the times of receipt of the frames are calculated. One or more frame period determining parameter values associated with the image sensors are altered if the time differences equal or exceed frame synchronization hysteresis threshold values. Parameter values are adjusted positively and/or negatively to decrease the time differences. The parameter values may be reset at each image sensor when the time differences become less than the frame synchronization hysteresis threshold value as additional frames are received at the video controller.

Abstract: Methods for automatic focus in a stereographic imaging device that includes two imaging sensor systems are provided. Focus searches are executed on both imaging sensor systems to determine optimal focused lens positions for each. The focus searches may be executed currently or sequentially, and may be at differing lens position granularities. Focal scores and spatial locations, i.e., the locations of focus regions, may be shared between the imaging sensor systems to coordinate the focus searches. Touchscreen coordinates may also be used to coordinate the focus searches.

Abstract: First and second views of a stereoscopic image are received. A first portion of the stereoscopic image is located at a first coordinate that is equal within the first and second views. For displaying enlarged versions of the first and second views, at least one of the first and second views is shifted, so that a second portion of the stereoscopic image is located at a second coordinate that is equal within the enlarged versions.

Abstract: Apparatus and methods disclosed herein operate to monitor times of receipt of start-of-frame indications associated with frames received from multiple image sensors at a video controller. Time differences between the times of receipt of the frames are calculated. Embodiments herein alter one or more frame period determining parameter values associated with the image sensors if the time differences equal or exceed frame synchronization hysteresis threshold values. Parameter values are adjusted positively and/or negatively to decrease the time differences. The parameter values may be reset at each image sensor when the time differences become less than the frame synchronization hysteresis threshold value as additional frames are received at the video controller.

Abstract: A method for automatic convergence of stereoscopic images is provided that includes receiving a stereoscopic image, selecting a face detected in the stereoscopic image, and shifting at least one of a left image in the stereoscopic image and a right image in the stereoscopic image horizontally, wherein horizontal disparity between the selected face in the left image and the selected face in the right image before the shifting is reduced.

Abstract: A method is provided that includes receiving coordinates of a touch point on a touchscreen, wherein the touch point indicates a user-selected convergence point, and converging a stereoscopic image at the user-selected convergence point based on the touch point coordinates.

Abstract: A method and apparatus for performing auto-convergence on a frame of a stereoscopic image or video based on at least one auto-focus point. The method includes retrieving a location of focus points from the image, estimating the disparity of focus points in the image, determining the disparity of the frame for the stereoscopic image or video, and shifting the frame to automatically adjust the convergence of the fame for the stereoscopic image or video.
