-Reference information-
The Y variable gamma curve characteristics can be checked using the PG function built into the DSP
(CXD3172AR) of the SS-HQ1 system. Output a Raster Horizontal Ramp (see
“Pattern Generator (PG)”. The curve characteristics can be checked as changes in the horizontal direction
luminance signal level through monitoring using an oscilloscope or waveform monitor.
10.4.3. Y Gamma OFF
You can select one of the lines in
“Y gamma OFF” in order to make the camera-side output linear,
such as for image data processing using digital output, or in cases where the receiving monitor has a gamma
correction function.
Fig 10.4-3 Y Gamma OFF
When YKNEESEL (or UYKNEESEL) is set to 6[h] or 7[h], the curve becomes a “Y gamma OFF”.
The line created by setting YGAMSEL (or UYGAMSEL) to 0[h] and setting YKNEESEL (or UYKNEESEL) to
5[h] will be the same as the line created by setting YKNEESEL (or UYKNEESEL) to 6[h].
