    摘要: An approach is provided for generating a high dynamic range image from a low dynamic range image. The generation is performed using a mapping relating input data in the form of input sets of image spatial positions and a combination of color coordinates of low dynamic range pixel values associated with the image spatial positions to output data in the form of high dynamic range pixel values. The mapping is generated from a reference low dynamic range image and a corresponding reference high dynamic range image. Thus, a mapping from the low dynamic range image to a high dynamic range image is generated on the basis of corresponding reference images. The approach may be used for prediction of high dynamic range images from low dynamic range images in an encoder and decoder. A residual image may be generated and used to provide improved high dynamic range image quality.

    摘要: A multi-primary conversion (5) of input drive values (RGB) defines a color of a pixel (PI) of a multi-primary display(DP) in an M dimensional color space (XYZ) into N>M output drive values (di) in an N dimensional drive space. The N output drive values (di) drive N sub-pixels (SPi) of the pixel (PI). The color of the pixel (PI) in the color space (XYZ) is defined by linear combinations of N color primaries of the respective N sub-pixels (SPi). The multi-primary conversion(5) comprises: defining a constraint in the color space (XYZ) thereby causing in the color space (XYZ) a convex polytope (U0; L0; V50) defined by vertex points (V10, V11, V12; V20, V21; V50), wherein only colors in the color space (XYZ) belonging to the convex polytope fulfill the constraint, determining exemplary solutions of the output drive values (di) for at least a subset of the vertex points (V10, V11, V12; V20, V21; V50), and constructing the output drive values (di) fulfilling the constraint as a convex combination of the exemplary solutions.

    摘要: A multi-spectral camera comprises a blocking element (201) having at least one hole (203) allowing light through. A dispersive element (205) spreads light from the at least one hole (203) in different wavelength dependent directions and a lens (207) focuses light from the dispersive element (205) on an image plane (209). A microlens array (211) receives light from the lens (207) and an image sensor (213) receives the light from the microlens array (211) and generates a pixel value signal which comprises incident light values for the pixels of the image sensor (213). A processor then generates a multi-spectral image from the pixel value signal. The approach may allow a single instantaneous sensor measurement to provide a multi-spectral image comprising at least one spatial dimension and one spectral dimension. The multi-spectral image may be generated by post-processing of the sensor output and no physical filtering or moving parts are necessary.

    摘要: In a method, unit and display device the input image signal is split into a regional contrast signal (VRC) and a detail signal (VD), followed by stretching separately the dynamic ranges for both signals, wherein the dynamic range for the regional contrast signal is stretched with a higher stretch ratio than the dynamic range for the detail signal. Preferably the stretch ratio for the detail signal is near 1 or preferably 1. In preferred embodiment highlights are identified and for the highlights the dynamic range is stretched to an even higher degree than for the regional contrast signal.

    摘要: A display system, comprises a multi-view display panel (10) adapted to display different images to different viewers in different directions. Imaging means (16) monitors viewers within a field of view and the display output is varied in dependence on the monitoring information provided by the imaging means. The invention thus provides a display display system which captures viewer information and uses this to control the display of multiple images at appropriate respective viewing angles. This enables information to be tailored to a particular viewer's characteristics or enables a user to be tracked as they move. Thus, different viewers can have personalised information when watching different views of the same display. This provides a dynamic view allocation system.
