摘要:
A multiple primary color display device includes a plurality of pixels located in a matrix including a plurality of rows and columns. The pixels are each formed of at least four sub pixels for displaying different primary colors, which can be sorted into n number of virtual pixels, and use each of the n number of virtual pixels as a minimum color display unit for providing display. The sub pixels which form each of the virtual pixels include a sub pixel common to another of the virtual pixels. When a line having a width corresponding to the n number of virtual pixels is displayed, two sub pixels which are located at both of two ends, in a width direction, of the line and display a certain identical primary color to each other have a luminance lower than the original luminance that the two sub pixels.

A method for correcting artifact effects is a multi-primary color matrix display is provided where the display is populated by an array of red-green-blue (RGB) pixels and of non-RGB pixels. The method includes receiving all-RGB data in an all-RGB format; converting the all-RGB data into multi-primary data in accordance with a predefined multi-primary color scheme, testing for and applying one or more artifact correction modifications to each of primary colors that is not represented by all pixels, wherein the modification includes shifting of intensity production of a given non-primary color to a metameric equivalent of pixels in one or more adjacent RGB pixels.

There is provided a signal processing device including a signal generation unit that generates a control signal for controlling an imaging device connected via one cable, a signal superimposition unit that superimposes the control signal generated by the signal generation unit on a video signal received from the imaging device via the cable without an influence on display of a video corresponding to the video signal, and a transmission unit that transmits the signals superimposed by the signal superimposition unit to the imaging device via the cable.

A method for color correcting an input color image having input color values adapted for display on a reference display device having a plurality of input color primaries to account to provide reduced observer metemaric failure on a narrow-band display device. A metamerism correction transform is applied to the input color image to determine an output color image having output color values in an output color space appropriate for display on the narrow-band display device. The metamerism correction transform modifies colorimetry associated with the input colors to provide output color values such that an average observer metameric failure is reduced for a distribution of target observers, and is formed responsive to a distribution of perceived color differences for a set of input colors that are determined for a set of target observers.

A method of color processing determines whether a pixel color is within at least one range of predetermined colors corresponding to a viewer expected color. If so, the method altering the pixel color to better approximate the viewer expected color. For detection of skin tones determining whether the pixel color is within a range of predetermined colors includes discounting an illuminant of the pixel color. The viewer expected colors are preferably skin tone, grass green and sky blue. The saturation level of grass green and sky blue are enhanced and that of skin tones are suppressed. The saturation s is limited based upon lightness J and hue h to convert to an allowable RGB color format range.

Adaptive video processing for a target display panel may be implemented in or by a decoding/display pipeline associated with the target display panel. The adaptive video processing methods may take into account video content, display characteristics, and environmental conditions including but not limited to ambient lighting and viewer location when processing and rendering video content for a target display panel in an ambient setting or environment. The display-side adaptive video processing methods may use this information to adjust one or more video processing functions as applied to the video data to render video for the target display panel that is adapted to the display panel according to the ambient viewing conditions.

The method comprises: either a first step of color gamut mapping applied directly to the incoming RGB color coordinates resulting into mapped source coordinates R″G″B″ and a second step where these source coordinates are transformed into target coordinates R′G′B′, or, a first step where the incoming source coordinates RGB are transformed into target coordinates R″G″B″ and a second step of color gamut mapping applied directly to the target coordinates R″G″B″ resulting into mapped target coordinates R′G′B′.

A color signal processing circuit of the present disclosure includes: a correction signal generation unit which generates, on the basis of a signal level of a color signal corresponding to one primary color among color signals corresponding to a plurality of primary colors being input, a correction signal for chromaticity of a color signal corresponding to another primary color as a difference value from a signal level of each color signal corresponding to predetermined chromaticity; and a correction unit which uses the correction signal generated by the correction signal generation unit to correct the color signal corresponding to the other primary color.

A method for viewing a simulated light output generated for a first display on a second display includes a variety of steps. First, the simulated light output is generated based on qualities of the first display. Next, the simulated light output is compensated for color differences, temporal differences, luminance differences including gamma difference, and differences in viewing environment between the first and the second display, in real-time. Then, the simulated light output that has been compensated for the differences and for viewing environment is output for the second display.
