VS-150 Advanced Application
RGB PARADE and White Balance Adjustment
i. Select PARADE mode on the VS-150 using the NEXT MODE option. Then point the camera at the white background
or white reference card.
ii. When the white balance is correctly adjusted, The RGB traces should be flat, balanced, and parallel to one another
in a straight line.
iii. When White balance is not correctly adjusted, the PARADE will show unbalanced trace.
iv. When the lighting is not evenly spread-out, the PARADE will show traces which deviate from the straight line.
v. If one of the RGB trace has one end higher than another, it means that the colour has lost its fidelity.
This undesired situation will occur if the camera is not adjusted correctly or you have an uneven colour temperature/
lighting on the background during white balancing.
Camera Noise
i. Adjust the IRIS of the camera to minimum or cap the lens.
ii. Select PARADE mode on the VS-150 using the NEXT MODE option.
iii. The noise value will be displayed on the chart. The thicker the value on the line chart, the greater the noise level.
The thinner the trace on the chart, the less the noisy it is
