In this paper, based on the experiments, we studied the feasibility on determining the transparency of the celluloid, and compared with looking contrast and spectrophotometry. It has been proved feasible that the color analyzer was used to determine the transparaency of the celluoid and colority difference was taken as a standard of our judgment.
The new CRT color analyzer can be used for measuring three basic color parameter of CRT screens:the chromaticity coordinates error of the white field,the white balance and the nonuniformity of the white field. The measurement results,including JND(just noticeable difference)and MPCD(minimum perceptible color difference)are displayed or printed with four modes. Eight kinds of different white reference can be stored into the CRT color analyzer.
The research focuses on the design of an automatic measurement & adjusting system by use of color analyzer board (Minolta color analyzer CA-210), which will be used in white balance adjusting to LCD TV with I~2 C bus interface or RS232 serial port.
The measurement results, including JND(just noticeable difference) and MPCD (minimum Perceptible color difference) are displayed or printed with four medes. Eight different white references can be stored into the color analyzer. The xy coordinates measurement error calibrated with the standard white illuminant is ±0.002.
Off-line color analyzer extracts the threshold of each color and real-time visual data processor uses the threshold to segment image, thereby recognizing the situation all around.
The setting of the color temperature was D65 and the monitor was calibrated with a color analyzer probe and SMPTE color bar.
