Window Blanking for Pan/Tilt/Zoom Camera

A window-blanking image sensor system, comprising:

• an image sensor;
• a computer memory storing program instructions in communication with the image sensor, the program instructions being loadable and executable by a processor, and when executed, cause the processor to:
• compute an absolute pan/tilt angle relative to world ground coordinates for each vertex of a privacy zone within a field-of-view for the image sensor;
• determine coordinates for each vertex based on an updated or predicted image sensor field-of-view;
• and
• block-out the privacy zone using the coordinates for each vertex.

A method of enabling window-blanking by a camera, comprising:

• obtaining a panoramic image for a pan/tilt/zoom camera;
• enabling a user to define at least one blanking zone within the panoramic image;
• and
• storing vertices of the at least one blanking zone in a manner that enables blanking of the at least one blanking zone during imaging by the camera.
