The system also has some input device attached, so the user can press some key there (just an example) and have a screenshot saved to the storage medium (an SD card, let’s say). A whole frame is quite big (1920 columns * 1080 lines * 2 color channels bytes, for a 4:2:0 1080p image let’s say means approx. 4.2MB), so wasting hardware resources (like LUT/BRAM) is not really possible.
