“…According to this criterion, the proposed method was compared to the conventional four-color matrix method [5] to confirm the effectiveness of the proposed method. The RGB primaries, the reference white, and Macbeth colorchecker colors used as testing colors are put on the (u 0 , v 0 ) chromaticity coordinates as shown in Figure 4 to evaluate the accuracy of color reproduction in 42-inch PDP-TV.…”

“…While the four-color matrix method [5] uses RGB primaries and a white for color correction, the proposed seven-color method partitions the (x, y) chromaticity diagram into three color regions based on hue as shown in Figure 3. Then, the color conversion matrix is made independently for three color regions.…”

“…Thus, there is more serious discrepancy for the color reproduction in PDP-TV. In order to correct color reproduction error in CRT, there exist three color correction methods: the four-color matrix method using RGB primaries and a white color [5], the analytic method using region separation in rg-plane [6], and the optimizing method using neural network [7,8]. Two methods except the four-color matrix method have disadvantages of requiring a great deal of measurement data and complex computation.…”

“…The color conversion matrices of PDP-TV and HDTV standard are made independently for three color regions by using luminance and chromaticity of seven colors. An efficient method of correcting color reproduction error based on relationship between the color conversion matrices of PDP-TV and those of HDTV standard is proposed to realize more improved color corrected images in PDP-TV than the four-color matrix method [5].…”

The displayed colors on PDP-TV screen are not exactly the same as the colors of the transmitted signal from broadcast HDTV because of color reproduction characteristics in PDP-TV. An efficient color correction method is proposed for displaying the digital HDTV-based video signal in PDP-TV by minimizing color reproduction error. It is composed of three correction matrices calculated by using luminance and chromaticity of seven colors. Experimental results show that the average color difference is reduced from 0.0299 to 0.0042 by using the proposed method. The average difference of the proposed method is 0.0021 lower in (u 0 , v 0 ) chromaticities than that of the conventional method.

“…In the U.S., color receivers are normally adjusted for a reference white point closer to 9300K + 27 MPCD (minimum perceptible color difference) because there has been a consumer preference for a very bluish white for TV. 18,21,22 The referencewhite of color video display units is selected at high CCT values by the TV manufacture, and this selected CCT value is quite different from the NTSC TV specification.…”

Abstract— A dynamic adaptation model (DAM), based on the variations in the luminance levels under the same chromaticity viewing conditions and equal‐whiteness correlated‐color‐temperature (CCT) curves (EWCCs) derived by using the proposed DAM, is proposed. The proposed model was obtained by the transformation of the test colors for high luminance into the corresponding colors for low luminance. In the proposed model, the optimal coefficients are obtained from the corresponding color data from Breneman's experiments. From the experimental results, it was confirmed that the chromaticity errors between the predicted colors by the proposed model and the corresponding colors of Breneman's experiments are 0.004 in u′v′ chromaticity coordinates. The prediction performance of the proposed model is excellent because this error is the threshold value that distinguishes two adjacent color patches. Equal‐whiteness CCT curves (EWCs) are also proposed using the proposed DAM. By using the proposed EWCCs, an analysis of the difference between the selected video‐display‐unit reference‐white CCT values can be made. Additionally, the proposed EWCCs can be used as the theoretical standard which determines the reference white of the color video display units.
