摘要： High dynamic range 3D images are generated with relatively narrow dynamic range image sensors. Input frames of different views may be set to different exposure settings. Pixels in the input frames may be normalized to a common range of luminance levels. Disparity between normalized pixels in the input frames may be computed and interpolated. The pixels in the different input frames may be shifted to, or stay in, a common reference frame. The pre-normalized luminance levels of the pixels may be used to create high dynamic range pixels that make up one, two or more output frames of different views. Further, a modulated synopter with electronic mirrors is combined with a stereoscopic camera to capture monoscopic HDR, alternating monoscopic HDR and stereoscopic LDR images, or stereoscopic HDR images.

摘要： Techniques are provided to encode and decode image data comprising a tone mapped (TM) image with HDR reconstruction data in the form of luminance ratios and color residual values. In an example embodiment, luminance ratio values and residual values in color channels of a color space are generated on an individual pixel basis based on a high dynamic range (HDR) image and a derivative tone-mapped (TM) image that comprises one or more color alterations that would not be recoverable from the TM image with a luminance ratio image. The TM image with HDR reconstruction data derived from the luminance ratio values and the color-channel residual values may be outputted in an image file to a downstream device, for example, for decoding, rendering, and/or storing. The image file may be decoded to generate a restored HDR image free of the color alterations.

摘要： Techniques are described to combine image data from multiple images with different exposures into a relatively high dynamic range image. A first image of a scene may be generated with a first operational mode of an image processing system. A second image of the scene may be generated with a second different operational mode of the image processing system. The first image may be of a first spatial resolution, while the second image may be of a second spatial resolution. For example, the first spatial resolution may be higher than the second spatial resolution. The first image and the second image may be combined into an output image of the scene. The output image may be of a higher dynamic range than either of the first image and the second image and may be of a spatial resolution higher than the second spatial resolution.

摘要： Techniques for configuring light conversion materials such as quantum dots in a display system are described. A display system includes light source components that emit a first light. The display system further includes a light converter illuminated by the first light. The light converter converts the first light into second light comprising one or more color components to support a specific color gamut. The second light forms, based at least in part on image data for images to be rendered, an emission pattern that varies with space and time.
