Single Camera Alignment
The alignment of a single camera against a reference comprises first the capture the chosen test
chart/scene by the camera to which you want to match other cameras, followed by the capture of
the same scene by the camera(s) under test.
1. Capturing the Reference Image
The reference image may be captured using the
Capture Reference
option on the Button Bar of
the 3D Meters display. This captures the current frame from Input 1 and adds it to the Gen
window.
Note:
The reference image can be saved and restored to the Generator window in the same way
as any other captured frame: it is only the name that is special.
Control Panel
Mouse & Keyboard
To capture a Reference image:
1.
Set up your ‘Reference’ camera in required fashion and focus on the Reference Test Chart
2.
Feed the input from the Reference camera into the port currently selected as Input 1.
3.
Call up either the 3D Meters display (as described above) or the Chroma Sabres display (see
Section I.9).
4.
Select
Capture Reference
button on Button Bar.
The current frame image is then captured and displayed on the Generator window as the pattern
Reference.yuv
.
To save the image for subsequent use:
Use the
Save
option from the Generator window’s Session menu to save the
Reference.yuv
pattern to your chosen location. Do NOT change the filename. (See Section Q.3 for further
details.)
2. Aligning the Test Camera
The following steps may be used to determine differences in set-up between a single ‘Test’
camera and the camera used when capturing the Reference image.

Either:
Capture a reference image as described above
Or:

(ii) Use the Generator window’s

against the selected Reference image.
