The metadata is then provided to a downlink data channel for color management.

Abstract: There are provided a method and system for color correcting displays with different color gamuts. The method includes performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut. The performing step includes mastering the source picture content to provide mastered color corrected picture content for display on the reference type displays having a reference color gamut. The performing step further includes generating metadata for a subsequent inverse color gamut mapping that color transforms the mastered color corrected picture content for display on non-reference type displays having a non-reference color gamut. The subsequent inverse color gamut mapping is an inverse operation of a color gamut mapping applied during the color correction to obtain the mastered color corrected picture content for display on the reference type displays having the reference color gamut.

Color correction is further provided in post production using the VMS to provide consistency across multiple display types.

Abstract: There are provided methods and systems for color correcting displays with different color gamuts. A method includes performing an initial color correction on source picture content using a reference type display having a reference color gamut to obtain mastered color corrected picture content for display on reference type displays having the reference color gamut.

Abstract: A technique for enabling display of a source color space on a display color space commences by first receiving source color space information. The source color space information undergoes a conversion into a device independent color space. Once converted into the device independent color space, a LUT or other matrix assigns output colors for the input colors corresponding to the specific display device color space. The LUT or other matrix can be generated with the source material and transmitted to the source display device.

Abstract: A system and method for compensating for average brightness dependency (ABD) differences between displays with and without average brightness dependency (ABD) includes color correcting source picture content on a reference display to output color corrected picture content. In addition, an ABD simulation process uses the color corrected picture content to simulate the display of content on the reference display. Subsequently, a compensation process receives the color corrected picture content and information from the simulation process and applies an ABD compensation characteristic to the color corrected picture content for correctly displaying the source picture content on a display with different ABD characteristics than the reference display.

Abstract: An imager achieves a desired image resolution by successively reproducing partial images which complement each other. The imager assigns pixels from an input image to the respective partial images according to complementing patterns that correspond to the pixel pattern of the imager. The imager reproduces the complementing pattern at different spatial positions, such that the complementing patterns merge. In order to avoid perceived double imaging of moving objects the image signal provided to the imager is assembled from an original image and a motion compensated interpolated image, which is derived from at least two consecutive images. Accordingly, every other partial image that is reproduced is derived from an interpolated image and takes into account movement of objects in the image that takes place between two consecutive images. In one embodiment the partial images are re-combined into one full image in a sequence that anticipates the distribution of the pixels used in the imaging device.

Abstract: A system and method for motion portrayal manipulation includes performing a motion estimation to determine objects in motion in content provided at an acquisition rate. An eye motion trajectory of a viewer is predicted based on the content to determine a region of interest. An object in the area of interest is filtered along an object trajectory to adapt motion of the object to permit display of the acquisition rate on a display device having a refresh rate other than the acquisition rate. The content is portrayed at the acquisition rate on the display device.

Abstract: A system and method for scaling images are provided. An upscaling algorithm or function is employed that increases the size of an image and then filters the upscaled image to remove aliasing artifacts. The system and method provides for acquiring an image of a first size, detecting the geometry of the image, scaling the image to a second size, and filtering the scaled image with at least one filter based on the detected geometry. During the filtering process, the edges of objects in the upscaled image are detected and different filter frequency responses are provided for the detected edges. Providing different filter frequency responses for the detected edges preserves more details for line images.

Abstract: A scalable video bitstream may have an H.264/AVC compatible base layer (BL) and a scalable enhancement layer (EL), where scalability refers to color bit depth. The H.264/AVC scalability extension SVC provides also other types of scalability, e.g. spatial scalability where the number of pixels in BL and EL are different. According to the invention, BL information is upsampled (TUp,BDUp) in two logical steps in adaptive order, one being texture upsampling and the other being bit depth upsampling. Texture upsampling is a process that increases the number of pixels, and bit depth upsampling is a process that increases the number of values that each pixel can have, corresponding to the pixels color intensity. The upsampled BL data are used to predict the collocated EL. A prediction order indication is transferred so that the decoder can upsample BL information in the same manner as the encoder, wherein the upsampling refers to spatial and bit depth characteristics.

Abstract: A display device produces color images by sequentially projecting monochromatic images. Multispectral light is projected via optical means and a filter arrangement with changeable primary color filters onto an imaging device. For each primary color the imaging device produces a number of constant-length pulses corresponding to a desired brightness level. The pulse length is chosen to be as short as possible for a first primary color. The pulse length for the other primary colors is adapted according to the respective share of the corresponding color filters in the color wheel. The time during which secondary colors are produced due to a transition between two primary color filters is increased by increasing the aperture of the optical means, by spatially relocating the focal point of the optical means for a disc-like filter arrangement, or by accordingly adding pure color light at the onset and the end of a transition between two color filter segments which produces secondary color light.
