The Color Uniformity indicator objectively evaluates the lens shading correction using a mathematical formula calibrated to human image quality perception. The lower the value, the better the image quality is. A value of 2.0 or less represents no loss of image quality. If the value is 2.0 or less then the indicator will be green. If the value is more than 2.0 but less than 3.0 the indicator will be yellow, and a value of 3.0 or more the indicator will be red. In those cases something may have gone wrong with the calibration and the source of the problem should be investigated. The problem area(s) will be highlighted with a red square. See Image #5 for an example.
Possible causes and resolutions of Color Uniformity failures are:
- Dust on the sensor; this will be indicated by one or several randomly situated red square. It may be possible to clean the sensor and run Lens Calibration again.
- The lens may be misaligned; this will be indicated by red squares situated on a single edge of the display. In some cases the lens can be adjusted.
- Good Color Uniformity is less than value may be too low for the given sensor; this will be indicated by red squares covering most of the image. Note that a value of 2.00 is based on evaluation and measurement of human perception to image quality, so increasing this value may resolve the Color Uniformity error but will result in overall lower image quality.
Note: The LSC setting will be saved to the EEPROM and the file regardless of the Color Uniformity result
