The color reproduction test module can complete the color reproduction, grayscale, white balance and other tests of each block in the 24-color card. Support manual and automatic, manual use is recommended.
Steps for usage:
1. Select the corresponding button on the main interface to enter the function module.
Figure 3.8.1 Parameter Settings
1. After clicking the OK button, select the map ('Automatic' without step 3)
2. After selecting the area, enter the fine-tuning interface. Refer to the gray-scale operation instructions for the operation of the fine-tuning interface.
3. Waiting for calculation results
1.1.1. Results display
The sample results are as follows:
Figure 3.8.2 'Automatic' analysis results
Description:
1. Selection requirements: the picture can not appear too much, too much noise point
2. Label description: from top left to bottom right, line by line traversal is from 1 to 24
3. Automatic analysis results page is not recommended
Figure 3.8.3 'Manual' analysis results - color reproduction
Figure 3.8.4 'Manual' analysis results - white balance error
Figure 3.8.5 'Manual' analysis results - color shift data
Figure 3.8.6 'Manual' analysis results - grayscale deviation
Figure 3.8.7 'Manual' analysis results - Grayscale results (incomplete)Description:
1. Manual module results are perfect
2. Features (eg noise analysis) to be developed
3. Recommended manual

Target density: Density value
Log Exposure: Exposure Log10, equal to the opposite of the density value
Pixel Level: Gray value of the pixel point
Gamma: Contrast, defined as Log (Exposure) - Log (Pixel Level / 255) curve slope average
exposure error: exposure bias unit: F-stops
1st the order:. 1 order
2nd order: 2-order
Nominal: theoretical density associated with Pixel Level / 255
WB error: error balance error WhiteBalance
exaggerated white Balance error: exaggerated white Balance error
K [Mireds]: Color temperature difference Mireds = 106 / (Degrees K)
Mean Camera Chroma (saturation): average camera chromaticity (saturation)
Color errors: color difference
Chroma corr: corrected color difference
Chroma uncorr: no correction Color difference
Mean: Average value
Max: Maximum value
W Bal: White balance error
Zones 2-5: Only 2-5 blocks of
