Abstract
Aspects of the present disclosure relate to video capture. In particular, aspects of the present related to systems and methods for reducing latency in the capture of video frames. Various implementations of the present disclosure may add extra pixels to a video frame so that visible pixels within each frame may be transferred faster through a video interface. In particular, adding extra pixels to a frame may cause an increase in a pixel clock that is generated based on the total number of pixels within each frame. As a result of the corresponding decrease in the time needed to transfer visible pixels in each frame, latency due to delay in a video capture process may be reduced.

A method comprising:
- for a first video frame image having a plurality of visible image pixels in a first display resolution, inserting the first video frame image into a source video frame having a second display resolution greater than the first display resolution;
- and
- compressing the first video frame image,
- wherein the source video frame is in a stereo 3D format having two image regions in the active display region,
- wherein said inserting the first video frame image includes inserting the plurality of visible image pixels and a plurality of extra pixels into an active display region of the source video frame,
- wherein said inserting the first video frame image includes inserting the plurality of visible image pixels into one of the two image regions and filling the other of the two image regions with the extra pixels.
