摘要： A video processing device which can be implemented as a peripheral device is disclosed. The video processing device is configured to receive one or more videos and audio through a plurality interfaces. Further, the device receives one or more user input corresponding to one or more customization requests of the received video and the audio. The video processing device processes the video and the audio based on the received user input and outputs the processed video and audio via an output interface.

摘要： A video system is provided. The video system, comprising: a plurality of imaging sensors each including an image signal processor; an image stitching engine analyzes un-stitched images generated by each of the plurality of imaging sensors. The un-stitched images are analyzed for a presence of face and then divided into a plurality of zones. A mapping function is implemented for each of the plurality of zones based on a number of consecutive frames in which presence of a face is analyses and a minimum number of frames in which a face was detected. A zoom engine determines a region of interest which includes a left edge and a right edge, wherein said left edge is set based on coordinates associated with a face detected in a left most zone of the unstitched images, and said right edge is set based on coordinates associated with a right most face detected in a right most zone of the unstitched images.

摘要： A three-dimensional imaging system for generating a 3D panoramic video/image is disclosed. The three-dimensional imaging system includes a plurality of stereoscopic pairs of compound cameras which are separated by a predefined distance d. The imaging system is configured to operate in a first mode to generate panoramic images simultaneously using the compound cameras. Spatial distortion and temporal distortion are calculated for each column in a region of overlap of the field of view of the panoramic images generated. The column for which the spatial and temporal distortion is minimum is marked as a seam location. The marked seam location is changed based on location of a motion in the column for which the calculated spatial and temporal distortion is minimum.
