Image-stream windowing system and method

An image-stream windowing system, comprising:

• a camera control device operable to:
• receive, from a camera located at a fixed position and having a fixed field of view, a high-resolution image stream of an object that moves while the camera captures the high-resolution image stream, the high-resolution image stream comprising a sequence of high-resolution frames,
• determine, for each high-resolution frame of the sequence of high-resolution frames, a respective window, of a sequence of windows corresponding to the sequence of high-resolution frames, that encloses the object within said each high-resolution frame, the camera control device being operable to determine the respective window based at least on the fixed position, the fixed field of view, and a position of the object, and
• generate a low-resolution image stream from the high-resolution image stream by cropping said each high-resolution frame with its respective window to create a respective one of a sequence of cropped frames, the low-resolution image stream comprising the sequence of low-resolution frames.
