What does Color Correction (CC) measure?

LightControl parameter CC.

  • What does it measure?
    • Discoloration of the rod lenses / color balance.
  • How does it measure it?
    • Color shift in the HSV model.
  • How does it relate to the previous measurement?
    • It uses an average reference value from a group of new scopes.

Broader explanation

This measurement is done to see discoloration due to the sterilization process.

It ensures quality within your process and alerts you when discoloration will cause misinterpretation of the image. This ensures patient safety.

The meauring device takes several images and measures shifts in color transmission using the HSV model. HSV stands for Hue, Saturation, Value and describes color. Since the description is done in three dimensions, we speak of a color space.

The three components are determined independently and together determine the color:

Hue is what we usually call "color", like a dot on the rainbow.

In the HSV model, the color is plotted on a circle, and the spot is indicated in degrees: Hue thus runs from 0 to 360 (degrees).

Saturation indicates the brightness of a color.

It is expressed in percentages and ranges from 0% (faint, gray) to 100% (full color).

Value of Brightness represents the lightness of the color.

Expressed as a percentage, it goes from 0% (black) to 100% (white).

The measuring device converts the images of the RGB camera to the HSV model and cross-references them with an average value of a group of new endoscopes known, specifically for this brand and type of endoscope known in the system.

Based on the measured value and the reference value, a score between 0 and 100% is given. A user can set the Pass/Fail value. Dovideq sets it at 70 as a standard.
