The following image presents the SDI output flow:
The out command selects the SDI output to be configured. The following table shows the
effected commands:
command out=1 out=2
colorconv CSM-1 CSM-2
sdi_range CSM-1 CSM-2
sdi_white CSM-1 CSM-2
sdi_black CSM-1 CSM-2
lut_preset LUT-1 LUT-2
lut_reset LUT-1 LUT-2
lut_interpolate LUT-1 LUT-2
lut_sample LUT-1 LUT-2
7.14 sdi2 <mode>
The SDI-2 output can be configured to support alternative modes.
Mode Function
0 (reset) Same signal as SDI-1 (mirrored)
1 Use of a separate LUT for SDI-2:
With this setting the camera can provide different gamma curves for the two
outputs.
2 DCT RAW12:
Y = upper 6 bits of sensor input (MSB aligned)
U/V = lower 6 bits of sensor input (MSB aligned)
3 DCT RAW10:
Y = upper 10 bits of sensor input (uses SDI extended values from 4...1019.
Raw is clipped to match this range)
U/V = 0x200 = 512 (to generate a gray scale image)
