Channel balance
All KODAK PIKE sensors and the SONY sensor (of Pike F-505) are read out via two
channels: the first channel for the left half of the image and the second channel
for the right half of the image (divided by a central vertical line).
All KODAK equipped cameras come with a sensor-specific pre-adjusted channel
balance.
However in some cases it may be advantageous to carry out a fine adjustment
with the so-called channel balance.
To carry out a gain adjustment in an advanced register: see Table 172:
Advanced register: Channel balance on page 352.
To carry out a dual-tap offset adjustment in an advanced register: see Table
173: Advanced register: Dual-tap offset adjustment on page 352
Channel adjustment with SmartView (1.5)
Prerequisites:
• Test sheet with continuous b/w gradient
• PIKE camera with defocused lens
• PIKE color cameras set to RAW8 or RAW16 (debayering: none)
• In case of using AOI, be aware that the middle vertical line (+/- 20 pixel)
is part of the AOI.
To carry out an adjustment in SmartView, perform the following steps:
1. In SmartView click Extras  Adjust channels... or use Alt+Ctrl+A.
Note

PIKE F-1100 and PIKE F-1600 can also be used in single-tap
readout mode, to prevent channel balance related problems.
See Sensor digitization taps (Pike F-1100/1600 only) on page
360ff.
Note

Automatic adjustment of gain (and offset) is implemented in
SmartView and is not available on register basis.
