Use the following functions to control or test
the camera’s
data output:
SDI Format
. Select the progressive scanning rate supported by your monitor.
Options are 23.98p, 24p; 25p; 29.97p, 30p; 50p; 59.94p, 60p.
Corrections
. The camera provides static Defective Pixel Correction (DPC) and Hot
Pixel Correction (HPC) independently or simultaneously. Static DPC and HPC
correction works with predetermined and preloaded pixel correction maps
created at the factory. The maps identify the coordinates of defective and hot
pixels. The camera uses these maps to correct the pixels during output.
Mirror
. Select Horizontal to flip the image horizontally. Select Vertical to flip the
image vertically.
Over/Under Shoot
. The SMPTE standard specifies data ranges for
overshoot/undershoot values. When enabled, overshoot words and undershoot
words provide for dynamic range “headroom” in processing. The
following table
provides the digital range assignments for different word sizes on a parallel signal
bus.
