    摘要: An emulator yields modified image data that predicts the appearance of image content on a target display. The emulator generates modified image data based in part on the image content. The emulator may perform a transformation in which one or more parameters representative of features such as black level and/or white level of the target display are functions of image statistics for the image content.

    摘要: Input video signals characterized by a source electro-optical transfer function (EOTF) are to be blended and displayed on a target display with a target EOTF which is different than the source EOTF. Given an input set of blending parameters, an output set of blending parameters is generated as follows. The input blending parameters are scaled by video signal metrics computed in the target EOTF to generate scaled blending parameters. The scaled blended parameters are mapped back to the source EOTF space to generate mapped blending parameters. Finally the mapped blending parameters are normalized to generate the output blending parameters. An output blended image is generating by blending the input video signals using the output blending parameters. Examples of generating the video signal metrics are also provided.

    摘要: A method and system for merging graphics and high dynamic range video data is disclosed. In a video receiver, if needed, video and graphics are translated first into the IPT-PQ color space. A display management process uses metadata to map the input video data and the graphics from their own color volume space into a target blending color volume space by taking into consideration the color volume space of the target display.

    摘要: An image processor receives an input image with enhanced dynamic range to be displayed on a target display which has a different dynamic range than a reference display. After optional color transformation (110) and perceptual quantization (115) of the input image, a multiscale mapping process (120) combines linear (125) and non-linear (130) mapping functions to its input to generate first (127) and second (132) output images, wherein the first and second output images may have a different dynamic range than the first image. A frequency transform (135, 140), such as the FFT, is applied to the first and second output images to generate first (137) and second (142) transformed images. An interpolation function (145) is applied to the first and second transformed images to generate an interpolated transformed image (147). An inverse transform function (150) is applied to the interpolated transformed image to generate an output tone-mapped image (152). The output tone-mapped image is post-processed to be displayed on the target display.

    摘要: A handheld imaging device has a data receiver that is configured to receive reference encoded image data. The data includes reference code values, which are encoded by an external coding system. The reference code values represent reference gray levels, which are being selected using a reference grayscale display function that is based on perceptual non-linearity of human vision adapted at different light levels to spatial frequencies. The imaging device also has a data converter that is configured to access a code mapping between the reference code values and device-specific code values of the imaging device. The device-specific code values are configured to produce gray levels that are specific to the imaging device. Based on the code mapping the data converter is configured to transcode the reference encoded image data into device-specific image data, which is encoded with the device-specific code values.

    摘要: Method and apparatus are provided for determining and adjusting drive values for a display comprising light source modulation layer such as a backlight array of LED and a display modulation layer such as an LCD panel. Image regions for which any of the display modulation layer drive values are above a predetermined threshold maximum value or below a predetermined threshold minimum value are flagged. The light source modulation layer control values determined for a subsequent frame of image data may be adjusted based on the flagged image regions. The adjustments to the light source modulation layer control values may reduce artifacts in the displayed image and increase the efficiency of the display.
