A facemask-mounted augmented reality (AR) display device is disclosed. In embodiments, the display device is hard-mounted to a breathing apparatus (e.g., oxygen mask, smoke mask) fitted to a user's nose and mouth behind a partially or fully covering external face shield. The AR display system includes display surfaces aligned with the eyes of the user and capable of providing the user with a forward field of view that moves with the user's head. The AR display system synthesizes streaming images with additional overlay sources (e.g., mission data, position data) to generate augmented reality content presented to the user within the field of view of the display surfaces.

A computer implemented method for rendering a page that includes one or more dynamic design elements into an output video is described. The method comprises processing the page to generate one or more layers, each layer being either a static layer associated with one or more static design elements of the page or a dynamic layer associated with a single dynamic design element of the page. Output frames are then generated using the layers and then encoded into the output video.

An image display apparatus is disclosed. The image display apparatus includes a signal processing device having a transceiver that includes a current sweep circuit configured to output a plurality of sweep currents, a current selector connected to the current sweep circuit and configured to select a predetermined current from the plurality of sweep currents based on comparison with a reference voltage, and a comparator configured to compare a voltage output from the current selector with the reference voltage. Accordingly, a constant output voltage level can be obtained.

A display apparatus including display, display driver, and processor configured to send input signal to display driver, first part and second part of input signal comprise first pixel data pertaining to portion of first image frame and second pixel data pertaining to second image frame, respectively, first part of input signal further comprises extra pixel data pertaining to second image frame. Display driver is configured to: re-scale pixels of first pixel data based on display resolution; update pixels of second pixel data based on extra pixel data; generate control signal based on re-scaled pixels and updated pixels; drive display using control signal to present visual scene, wherein re-scaled pixels surround updated pixels when displayed on display area.

A time code display system comprising: a video receiver configured for receiving a plurality of non-homologous video signals; a time code parser connected with the video receiver and configured for extracting time code data of each video frame from each video signal; a write controller and a buffer, the write controller being connected with the video receiver and the time code parser; a synchronous clock component configured for generating a local clock signal according to a channel associated clock signal of any video signal; and a read controller and a display, the read controller being connected with the synchronous clock component and the buffer and configured for reading out the video frame of each video signal and the time code data corresponding to the video frame from the buffer at the same time, according to the local clock signal.

Content presented on a display screen is updated responsive to a user input. Content is retrieved and segmented into bands that are rendered onto the display screen incrementally to provide a visual effect similar to an animation. A band is rendered at a starting location and after a refresh interval passes a subsequent band is rendered at a second starting location. The bands may be rendered until the content is shown on the display screen.

A frame processor may generate a mask based on one or more static regions of a first set of frames of a plurality of previous frame and adjust the mask to at least one of determine alpha data or conceal distorted content associated with the one or more static regions of the first set of frames. The distorted content may be caused by extrapolation of a frame from a second set of frames of the plurality of previous frames. The frame processor may generate a composite frame based on application of at least one of the mask or the alpha data to a previous frame of the plurality of frames, and application of the previous frame based on the at least one of the mask or the alpha data to the frame extrapolated from the second set of frames of the plurality of previous frames.
