摘要： 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.

摘要： 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.
