OmniTek OTR 1001 User Guide, v3.1 I-26
The display comprises a set of diamond-shaped plots, one for each colour component, comparing
the colour values at each pixel in the ‘test’ image i.e. the image being compared (the Right-eye
image in the case of Stereo 3D video) against those of the corresponding pixel in the reference
image (the Left-eye image in the case of Stereo 3D video). Figures are given below each sabre
for the average percentage difference in Gain and Lift (as determined by comparing the right-eye
image against the left-eye image).
If the Gain and Lift applied to the two images were identical, each of the three plots would
comprise a single vertical line running from the bottom of the diamond to the top. But in
practice, the plots tend to feature a mass of points scattered around the vertical but biased either
to the left or the right.
To interpret these distributions, a best-fit line is drawn through the points, the features of which
are interpreted as a difference in Gain and Lift between the test image and the reference image.
Where the line leans to the right, the Gain is greater in the test image (i.e. the Right-eye image in
the case of Stereo 3D video) and less in the reference image (i.e. the Left-eye image in Stereo 3D
video): this is shown as a positive value. Where it leans to the left, the Gain is greater in the
reference image: this is shown as a negative value. The Lift is given by the offset from the origin
at the bottom of the plot – again positive when in the right half of the plot and negative when in
the left half.
Adjustments made to the set-up of the cameras from which the images are being taken are
immediately reflected in the Chroma Sabres display, making this display useful in Camera Rig
Alignment (see Section I.8).
