An apparatus generates an image signal in which pixels are encoded in N-bit words which encode at least a luma per pixel. A receiver (201) obtains high dynamic range pixel values in accordance with a first color representation in M-bitwords. A first generator (203) includes the high dynamic range pixel values in the image signal in the N-bit words according to a second color representation. A second generator (205) includes in the image signal an indicator that high dynamic range pixel values are encoded. In some examples, the high dynamic range pixel values may be provided in a segment that can alternatively contain high or low dynamic range pixel values, and the indicator may indicate which type of data is included. The approach may e.g. facilitate introduction of high dynamic range capability into e.g. HDMI systems.

The results are written through the apparatus into a color profile of the color display device.

Two-dimensional and three-dimensional optical coherence tomography is obtained by differential imaging of full-frame interference images using a white light source. Full-color tomographic imaging is also possible by processing the three-color channels of the interference images. A technique is described to obtain two-dimensional OCT images with full natural color representation. In a particular embodiment, the interference image is acquired using a color camera and the three-color channels are processed separately, recomposing the final image. In an additional embodiment, the interference images are acquired using separate red, blue and green light sources and the three color channels are combined to recompose the final image.

An ultrasound machine is disclosed that displays a color representation of moving structure, such as a cardiac wall tissue, within a region of interest on a monitor. The color representation is generated by displaying at least one color characteristic corresponding to a movement parameter of the structure, such as velocity or strain rate. The movement parameter is mapped to the color characteristic by apparatus comprising a front-end that generates received signals in response to ultrasound waves. A Doppler processor generates a set of parameter signals representing values of the movement parameter within the structure. A control processor adaptively generates a mapping function based on the distribution of the parameter signals to map the parameter signals to a set of color characteristic signals. A display processor applies the mapped values of the color characteristic legend to the values of the movement parameter representing the moving structure, to display a color representation on the monitor in response to the mapping function.

An image is transferred from a sender to a receiver. The image is progressively re-created at a display of the receiver. First, a low-resolution full-color representation of the image is transferred. Then, a full-resolution limited-color representation of the image is sent. The pixel values of the full-resolution representation typically represent alpha-numerical characters or edges of features. The representations are combined to create a version of the image by modifying the pixels of first representation under control of the limited-color content of the spatially corresponding pixel of the second representation. The legibility of the combined image is achieved considerably faster than with conventional techniques.

In a high quality image-encoding scheme an input image is decomposed into several image blocks comprising multiple image elements. The image blocks are encoded into encoded block representations. Such a block representation comprises two color codewords, a color modifying codeword and optionally a sequence of color indices and color modifier indices. The color codewords define multiple discrete color representations along a line in color space. The color modifying codeword represents a set of multiple color modifiers for modifying the multiple color representations along at least one extension vector to obtain, for each color representation, a set of multiple color points. These color points of the multiple sets are located on a surface defined by the multiple color representations and the at least one extension vector. The colors of the image elements in the block are then approximated by these color points on the surface.

A pixel structure for a flat panel display apparatus displaying images using a plurality of pixels, each of the pixels including six or more sub-pixels. The flat panel display apparatus including the pixel structure is free from a color fringe error, and the pixel can include three or more primary colors.

A parallax representation unit in a displayed image processing unit uses a height map containing information on a height of an object for each pixel to represent different views caused by the height of the object. A color representation unit uses, for example, texture coordinate values derived by the parallax representation unit to render the image, shifting the pixel defined in the color map. The color representation unit uses the normal map that maintains normals to the surface of the object for each pixel to change the way that light impinges on the surface and represent the roughness accordingly. A shadow representation unit uses a horizon map, which maintains information for each pixel to indicate whether a shadow is cast depending on the angle relative to the light source, so as to shadow the image rendered by the color representation unit.

The present System For Highlighting A Dynamic Personalized Object Placed In A Multi-Media Program functions to manage the delivery of Object (product) placements in a Multi-Media Program. The multi-media object highlighting system controls the retrieval of Object data that comprises a product representation and the integration of this Object data into a corresponding selected one of the predetermined Multi-Media Object Locations which are components of the Multi-Media Program. In addition, the multi-media object highlighting system produces a representation of the object that highlights the object in the scenes in which it appears. The highlighting can be any human sensible characteristic, such as, but not limited to: flashing, changes in brightness, movement, change in representation, and the like. The highlighting can also include the use of an anomaly, such as a color representation in a black and white multi-media program or vice versa, or out-of-context object.
