    摘要: A non-transitory machine readable medium that has a computer program for adjusting color values of an image represented in a color space is described. The image includes a set of pixels. Each pixel includes a set of color values. The computer program displays a composite bump on a tonal adjustment graph that is defined along a particular color component of the color space. The composite bump is generated by blending several bumps on the tonal adjustment graph. In response to receiving an input on a location on the tonal adjustment graph, the computer program creates a new bump based on the input and blending the new bump with the composite bump to create a modified composite bump. The computer program adjusts the color values of the image based on the modified composite bump.

    摘要: A method and apparatus for processing an image signal includes an image signal encoding apparatus and an image signal decoding apparatus that use an independent luminance and chrominance image signal to reduce a crosstalk. The independent luminance and chrominance image signal may include a luminance signal and a chrominance signal. The image signal encoding apparatus and the image decoding apparatus may perform down-sampling or up-sampling on the chrominance signal. The image signal encoding apparatus and the image decoding apparatus may increase a compression efficiency of the independent luminance and chrominance image signal, by applying different quantization parameters and different bit-depths to the luminance signal and the chrominance signal, respectively.

    摘要: A new framework for video compressed sensing models the evolution of the image frames of a video sequence as a linear dynamical system (LDS). This reduces the video recovery problem to first estimating the model parameters of the LDS from compressive measurements, from which the image frames are then reconstructed. We exploit the low-dimensional dynamic parameters (state sequence) and high-dimensional static parameters (observation matrix) of the LDS to devise a novel compressive measurement strategy that measures only the dynamic part of the scene at each instant and accumulates measurements over time to estimate the static parameters. This enables us to lower the compressive measurement rate considerably yet obtain video recovery at a high frame rate that is in fact inversely proportional to the length of the video sequence. This property makes our framework well-suited for high-speed video capture and other applications. We validate our approach with a range of experiments including classification experiments that highlight the purposive nature of our framework.

    摘要: In the video signal processing device, the first color space converting section performs color space conversion on an input video signal, to generate a converted video signal configured of H, S and V signals. The first high-frequency separating section separates a high-frequency component from the luminance signal in the input video signal, to generate high-frequency luminance signals. The combining section performs a combining process based on the V signal or the S signal or both, and the high-frequency luminance signal, to generate a combined V signal or a combined S signal or both. The second color space converting section performs color space conversion on a video signal, configured of the H signal, the S signal or the combined S signal, and the V signal or the combined V signal, to generate an output video signal defined in RGB color space.

    摘要: In a first embodiment, a display system comprises a display panel with 4 or more colored subpixels. The display system receives input image data specified in a first color space and outputs image data specified in a second color space. The display system further comprises a gamut mapping module for mapping the input image data specified in the first color space to image data specified in the second color space. The gamut mapping module clamps out-of-gamut colors using at least a first clamping system and a second clamping system. The first and second clamping systems yield first and second clamped values. A weighting module produces a resulting clamped value from the first and second clamped values. A final output image value is derived from the resulting clamped value. Other embodiments of the display system include pre-reduction modules and adjustable GMA modules.

    摘要: Techniques are provided to encode and decode image data comprising a tone mapped (TM) image with HDR reconstruction data in the form of luminance ratios and color residual values. In an example embodiment, luminance ratio values and residual values in color channels of a color space are generated on an individual pixel basis based on a high dynamic range (HDR) image and a derivative tone-mapped (TM) image that comprises one or more color alterations that would not be recoverable from the TM image with a luminance ratio image. The TM image with HDR reconstruction data derived from the luminance ratio values and the color-channel residual values may be outputted in an image file to a downstream device, for example, for decoding, rendering, and/or storing. The image file may be decoded to generate a restored HDR image free of the color alterations.
