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 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.

摘要: Displays, display components, image and video processing apparatus and related methods are described. A method for driving local-dimming displays comprises generating control values for driving pixels of a spatial light modulator from one image data component and generating control values for driving backlight elements from a second image data component. The first and second image data components may respectively comprise a tone map and a ratio image. Control values for the spatial light modulator and/or backlight may be obtained using cost effective hardware.

摘要: Modulated light sources are described. A modulated light source may have first light sources that are configured to emit first light, which has first color components that occupy a range that is beyond one or more prescribed ranges of light wavelengths. The modulated light source may also have a light converter that is configured to be illuminated by the first light. The light converter converts the first light into second light. The second light has one or more second color components that are within the one or more prescribed ranges of light wavelengths. Strengths of the one or more second color components in the second light are monitored and regulated to produce a particular point within a specific color gamut.

摘要: Display backlight units are controlled with a signal. A message has an address header specifying one of an array of backlight units, and instructions for individually controlling each of the backlight units, particularized accordingly. The message is routed from a controller to a first controllable backlight unit of the display, which controllably responds to its corresponding particularized instructions. The message is sequentially routed in order from each backlight unit to the next in a chained ring configuration. Data from the backlight units is similarly routed back to the controller.

摘要: Techniques for 3D back light units are described. In some possible embodiments, in a first time interval during which one or more back light units of a display system are turned off, a complete set of left pixel values in a left frame is outputted to a display panel of the display system. In some possible embodiments, in a second time interval during which the complete set of left pixel values in the left frame has been outputted to the display panel of the display system, the one or more back light units are turned on to illuminate the display panel and the second time interval is subsequent to, and is not overlapped with, the first time interval.
