    摘要: Techniques for operating a display system in a wide range of ambient light conditions are provided. An intensity of ambient light on a display panel may be detected. The display panel may be illuminated by light sources in addition to the ambient light. An individual light source may be individually settable to an individual light output level. If it is determined that the luminance level of the ambient light is above a minimum ambient luminance threshold, an ambient black level may be calculated using the intensity of ambient light. Light output levels of one or more of the light sources may be elevated to first light output levels. Here, the one or more light sources may be designated to illuminate one or more dark portions of an image. The first light output levels may create a new black level equaling the determined ambient black level.

    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: A decoder receives for decoding and post-processing for display an HDR (high dynamic range) image comprising a first coded image (e.g., a JPEG-HDR baseline image) and a second coded image (e.g., a JPEG-HDR ratio image). The first coded image is partially decoded and post-processed according to a post-processing command (e.g., scaling) to output a first decoded and post-processed image. The second coded image is also partially decoded and post-processed according to the post-processing command to output a second decoded and post-processed image. The first and the second decoded and post-processed images are combined to output a decoded HDR image according to the post-processing command.

    摘要: Techniques for stereoscopic 3D display systems with active shuttered glasses are provided which overcomes the real-world limitations of sample/load & hold displays, resulting in greater overall brightness, while reducing crosstalk between each eye perspective. In some embodiments, a first left-eye perspective frame and a first right-eye frame are determined from image data. A first composite frame of a first type is then created. This first composite frame of the first type comprises one or more left-eye pixel values from the first left-eye frame and one or more right-eye pixel values from the first right-eye frame. The first composite frame of the first type is outputted to the display area. This may also include use of scanning backlight synchronized to loading/hold of display in conjunction with the composite frame.

    摘要: Techniques for displaying images of different dynamic ranges in a display system are provided. In some embodiments, images that have a number of dynamic ranges may be normalized to a configured dynamic range that corresponds to the full intensity reproduction capability of the device. The configured dynamic range may be wider, greater, or deeper than the relatively limited dynamic range.

    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: HDR images are coded and distributed. An initial HDR image is received. Processing the received HDR image creates a JPEG-2000 DCI-compliant coded baseline image and an HDR-enhancement image. The coded baseline image has one or more color components, each of which provide enhancement information that allows reconstruction of an instance of the initial HDR image using the baseline image and the HDR-enhancement images. A data packet is computed, which has a first and a second data set. The first data set relates to the baseline image color components, each of which has an application marker that relates to the HDR-enhancement images. The second data set relates to the HDR-enhancement image. The data packets are sent in a DCI-compliant bit stream.

    摘要: Techniques are provided to generate high or wide dynamic range image from two or more input images of different exposure settings by directly merging coefficients derived from the input images in a transform domain. Energy values may be determined from coefficients blocks derived from the input images. The energy values may be compared with thresholds to determine weight factors for the coefficient blocks. An output coefficient block in the transform domain, used in or used to generate the output image, may be determined as a weighted combination of the coefficient blocks in the transform domain derived from the input images. If input images are compressed in transform domain, an output image can be generated without performing decompression in transform domain.
