Based on the host chip of FPGA
it designed digital video conversion equipment
and completed the conversion between video with SD-SDI interface and Camera Link. After collecting the video from the camera
demosaicing
converting the color space
de-interlacing
interlacing and other operation
the circuit implemented the real-time video conversion between both different interfaces. With much flexibility
high integration and less hardware resources
the whole system completed a high-quality video solution. 2010 IEEE.

A standard white light compounding algorithm based on combination of CCD illumination acquisition with computer control is presented for LEDs. The computer adjust and control the working current of LEDs by using three-color LEDs illumination acquired by CCD camera
achieved chromaticity coordinates error between compounded white light and standard white light D65 less than the threshold beforehand setted by this technique
then acquiring needed standard white light. Compounded white light meet the chromaticity error demand that is able to be changed
at the same time the CCD illumination acquisition system is eliminated. The proposed algorithm improved the light energy utilization efficiency of LED
and eliminated the offset of central wavelength and chromaticity coordinates due to work current change of LEDs. Experimental results show that the proposed algorithm achieved lesser chromaticity error uv=0.001 relative to standard white light D65
enhanced chromaticity uniformity of illumination field.

The biochemical analysis in medicine is an important inspection and diagnosis method in hospital clinic. The biochemical analysis of urine is one important item. The Urine test paper shows corresponding color with different detection project or different illness degree. The color difference between the standard threshold and the test paper color of urine can be used to judge the illness degree
therefore
it can be used in hospital
so that further analysis and diagnosis to urine is gotten. The color is a three-dimensional physical variable concerning psychology
the estimation method of color difference in urine test can have better precision and facility than the conventional test method with one-dimensional reflectance
calibrating organization and family
while reflectance is one-dimensional variable
it can make an accurate diagnose. The digital camera is easy to take an image of urine test paper and is used to carry out the urine biochemical analysis conveniently. On the experiment
so its application prospect is extensive.
the color image of urine test paper is taken by popular color digital camera and saved in the computer which installs a simple color space conversion (RGB &rarr XYZ &rarr L*a*b*) and the calculation software. Test sample is graded according to intelligent detection of quantitative color. The images taken every time were saved in computer
and the whole illness process will be monitored. This method can also use in other medicine biochemical analyses that have relation with color. Experiment result shows that this test method is quick and accurate

Munsell color system is selected to establish the mutual conversion between RGB and L*a*b* color model for camera. The color luminance meter and CCD camera synchronously measure the same color card
XYZ value is gotten from the color luminance meter
the training error is 0.000748566
it can show that the method combining second general revolving combination design with genetic algorithm can optimize the hidden-layer structure of neural network. Using the data of testing set to test this network and calculating the color difference between forecast value and true value
the color picture captured from CCD camera is expressed for RGB value as the input of neural network
and the L*a*b* value converted from XYZ value is regarded as the real color value of target card
which the difference is not obvious comparing with forecast result
the maximum is 5.6357 NBS
namely the output of neural network. The neural network of two hidden-layers is considered
the minimum is 0.5311 NBS
so the second general revolving combination design is introduced into optimizing the structure of neural network
and the average of color difference is 3.1744 NBS.
which can carry optimization through unifying project design
data processing and the precision of regression equation. Their mathematics model of encoding space is gained
and the significance inspection shows the confidence degree of regression equation is 99%. The mathematics model is optimized by genetic algorithm
optimization solution is gotten
and function value of the goal is 0.0007168. The neural network of the optimization solution is trained
