Abstract:
A method of recording video images, the method comprising:providing a stream of video images, the images having an associated two-dimensional frame bounding the corresponding visible extent of the images, the frame being selectively and dynamically divisible into a plurality of two-dimensional frame portions that collectively comprise the frame, each portion having attributes including image resolution;for at least a first and second number of the video images, digitally storing information corresponding to each frame portion at a selected one of a plurality of image resolutions, the plurality of image resolutions including a first and second image resolution;for the first number of the video images, establishing the stored image resolution of the frame at a single resolution of the plurality of image resolutions;monitoring for a predefined trigger event;defining at least a first and second of the frame portions within the video images; andfor the second number of the video images and subsequent to the trigger event and the defining step, establishing the stored image resolution of the first frame portion at the first image resolution while simultaneously establishing the stored image resolution of the second frame portion at the second image resolution, such that each of at least some of the digitally stored video images have associated multiple coincident image resolutions corresponding to multiple frame portions.
