Various embodiments relate to systems and methods for simultaneously switching input image streams to output devices, while providing optional image processing functions on the image streams. Certain embodiments may provide vision systems and methods suitable for use in vehicles, particularly windowless vehicles, such as armored ground vehicles, submerged watercraft, and spacecraft. Some embodiments may enable sharing of image streams (e.g., with one or more other vehicles), generation of panoramic views (e.g., from various camera feeds), intelligent encoding of image streams, and implementation of security features based on image streams.
