Abstract
The present invention utilizes video compression techniques in providing multi display and user control of picture layout with a single non-mechanical camera. According to a preferred embodiment of the present invention, a subsection of interest within a general view captured by the camera is coded based on the prediction of the main picture. In one aspect of the embodiment, scaling of the predicted pixel values in the subsection to match with the corresponding raw pixel data of extended resolution is carried out before subtracting the prediction from the raw data to provide the residual in the coding process. In a second aspect, the frame rate and the number of quantization intervals are increased when coding the subsection relative to the coding of the general view.
