Abstract
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.
