| description | A system including a camera, display screen and processing device. A privacy mask obscures a portion of the displayed images. The processing device transforms the privacy mask in accordance with changes in the field of view of the camera, wherein, in a first field of view, the privacy mask is defined by a plurality of vertices having coordinates (x1, y1), . . . (xn, yn), and, in a second field of view, the processing device determines transformed coordinates, (x1', y1'), . . . (xn', yn'), for each of the vertices based upon changes in the field of view of the camera. The privacy mask is definable by pixel rows and the processing device identifies opposing ends of a plurality of the pixel rows, each of the identified ends defining one vertex of the privacy mask. The privacy mask may also include an unmasked area completely encircled by masked area. |
