3D: Picture Analysis (where included)
Specifies the conditions under which the OTR should report as errors:
The percentage of pixels that have an apparent depth that is either nearer to the viewer than
the specified minimum distance or further than the specified maximum distance. (These
minimum and maximum distances are recorded on the
System page of the Config window.)
The percentage of points in the left-eye and right-eye images that are not matched.
The difference in Sharpness between the left-eye and right-eye images (the Sharpness
Delta) as indicated on the
3D Meters display
3D: Camera Alignment (where included)
Defines the values of camera rotation, the difference in camera zoom level, camera horizontal
offset and camera vertical offset above which errors should be reported.
3D: Picture Levels (where included)
Defines the percentage differences in gain and lift at which errors/warnings should be raised
(calculated by comparing the right-eye image value against the left-eye image value).
Picture Quality (where included)
Specifies the required values for the following parameters:
The Duration for which the PQA Charts are displayed, expressed as a number of frames.
The number of complete sequence loops that are captured by the OTR when the Sync
capture option is selected (see Section S.5).
The error threshold used when comparing a new graph trace capture against the
‘Gold’
reference capture file. (Applies only to operation under remote control: see Section S.7)
The Drop Speed and Climb Speed applied in generating the PQA Charts. It is normal to
leave both controls set to 100, so that the graphs directly reflect the calculated data.
However the charts can be made to emphasise quality by setting a high Climb Speed
alongside a low Drop Speed, while errors can be emphasised by setting a low Climb
Speed alongside a high Drop Speed.
Ticking Auto apply gain/offset compensation sets the OTR to transfer the gain and offset
values as well as the frames value when the Auto button on the PQA Toolbar is selected.
Ticking the Enable mask option limits the PQA analysis to the part of the active image
that remains when the numbers of pixels/lines defined as Left, Right, Top and Bottom are
masked out from the edges of the active image. When unticked, the analysis is limited to
the Region of Interest that has been defined (see Section E.2).
Plus for PSNR etc.
The Error Levels that determine the threshold for pass/fail, event-based logging of
PSNR etc.
The associated Timeouts which smooth the reporting of errors by requiring the error
condition to be in place for a minimum number of frames before the error is reported.
The Weightings to be used in calculating the overall Combined Picture Quality (CPQ),
expressed as a percentage. Note: The total of the weightings set needs to add up to 100.
The Edge Compensation Threshold used in calculating CSNR values (see the
description of the CSNR algorithm in the PQA Application Guide , available from the
OmniTek website).
