Ein Auzug aus dem Patent lautet wie folgt:

„The recording of successive frames of raw sensor data depicting a moving scene is provided. The raw sensor data comprises pixel data for an image sensor having pixels arranged in correspondence to a mosaic of plural different colors in a color filter array. A first sampling mosaic pattern for sampling the pixel data at a first resolution is designated. A second sampling mosaic pattern for sampling the pixel data at a second resolution which is lower than the first resolution is designated. One of the first or the second sampling mosaic patterns is selected for a frame by applying a predetermined rule. Pixel data of the frame is sampled using the selected sampling mosaic pattern. The sampled pixel data for the frame is recorded onto a recording medium.“
