Abstract: Examples are described of marking specified regions of stored image frame buffer data in an image frame buffer. An imaging system can read the specified regions of the image frame buffer to identify whether the marking has been overwritten or not. The imaging system can thus efficiently identify how much of the image frame buffer has been overwritten with data from a new image frame. Based on this, the imaging system can retrieve partial image frame data from the image frame buffer and can process the partial image frame data, for instance to composite the partial image frame data with virtual content and/or to perform distortion compensation. The processed partial image frame data can be uploaded to a display buffer and displayed by a display, either as-is or once more of the frame is captured and processed. The imaging system can also perform auto-exposure using the partial image frame data.

Abstract: Techniques and systems are provided for image processing. For instance, a process can include: receiving an initial image rendered at a first time interval, the initial image having a larger field of view as compared to a field of view of a display; generating a mesh of vertices for the initial image, at least one vertex of the mesh corresponding to a portion of the initial image with the larger field of view; reprojecting the mesh of vertices based on a view angle change since the first time interval to obtain a reprojected mesh; generating estimated distortion information for the at least one vertex of the reprojected mesh corresponding to a portion of the initial image with the larger field of view; pre-distorting the reprojected mesh based on the estimated distortion information; and rasterizing the initial image based on the pre-distorted reprojected mesh to generate a reprojected image.

Abstract: Image processing can include storing a first image and a second image in response to a first command. The first image can be captured by a first camera and comprise first pixels and have a first field of view. The second image can be captured by a second camera and comprise second pixels and have a second field of view. A second command can be received and the first image can be edited based on the second command. The edited image can have a third field of view and comprise pixels based on the first pixels and the second pixels.

Abstract: Image processing can include storing a first image of a scene captured by a first camera, storing a second image of the scene captured by a second camera, and storing a first user-composed image. The first user-composed image can be derived from at least one of: (a) the first image and (b) the second image. The image processing can further include: receiving a second command to edit the first user-composed image, editing the first user-composed image, and saving the edited first user-composed image as a second user-composed image.
