3 results about "Parallel image processing" patented technology

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 enable multiple users / viewers to collaboratively control such systems and methods. Additionally, some embodiments may enable control by a set of computer input devices (e.g., keyboard and mouse) to switch between multiple computer systems, possibly by following the movement of a computer input device cursor, between virtual displays, as the cursor is controlled by the set of computer input devices.

The invention provides an encodable liquid crystal image processor, a preparation method and a broadband parallel imaging device. The encodable liquid crystal image processor comprises a first substrate, a second substrate and a cholesteric liquid crystal layer which are oppositely arranged, one side of the first substrate is provided with a first orientation layer, and one side of the second substrate is provided with a second orientation layer; the first orientation layer and the second orientation layer comprise control patterns, and the control patterns enable liquid crystal directors to meet orientation angle distribution so as to guide liquid crystal distribution in the cholesteric liquid crystal layer; in a wave band covered by a chiral photonic band gap of the cholesteric liquid crystal layer, space parallel image processing with multiple functions is realized at the same time. According to the invention, a multi-task image processing function, such as edge detection and corner detection, is integrated on a single element, and spatial parallel output is realized in a visible light wave band by utilizing the broadband geometric phase modulation characteristic of cholesteric liquid crystal, so that the limitations of single function and narrow bandwidth of an existing image processing device are effectively improved.
