Important - Sony SS-HQ1 Application Notes

10.10.2. Important

The following points are important to keep in mind in relation to mask function settings.
1. Eight masks can be simultaneously displayed or stacked on top of each other, but it is not possible to
change the brightness signal level and colors separately for each mask. (0th hold does change
individual masks.)
2. Masks are not linked to MIRROR.
3. Note that the mask will not be displayed if the MSKnHRST value is smaller than the MSKnHSET value,
or if the MSKnVRST value is smaller than the MSKnVSET value.
4. Set MSKnVSET parameter values at 7h or higher. (If they are set under 7h, the mask start position
during 0th hold would exceed the period of the effective video signal, so the "held" color would be
incorrectly displayed.)
5. Set all MSKnHSET parameter values at 2h or higher. (If they are set under 2h, the mask is not
displayed.)
6. With 0th hold, shooting in dark conditions (when the iris is closed, for example) may make the masked
areas appear to oscillate. This is caused by random noise, not a problem with the mask function.
7. Under regular mask settings, the mask edges may appear blurred in some cases. This is due to a
mismatch of the mask Y and CR delay adjustments. Adjust them by the following parameters.
• MSKDLY (CAT9_Byte37)
• MSKDLC (CAT9_Byte38) Mask signal
Mask signal Y-side delay adjustment
CR-side delay adjustment
