Most of the data for these parameter selections can be obtained from the user
and/or service manuals that are supplied with the non–standard camera. Here
is a brief description of each parameter selection field and box in the
Camera Type
edit panel.
•
H.Scan Mode –– This box selects either a normal speed or a double
speed scan mode. The basic difference is that a normal speed camera
acquires 240 vertical lines of data in 17ms, while a double speed camera
acquires 480 vertical lines of data (a “full” frame) in 17ms. The double
speed camera also has frame reset capability.
•
V.Scan Mode –– This box selects interlaced operation using one or two
fields, or non–interlaced operation, according to the camera type in use.
For the 2801–YC and –YD cameras,
Interlaced, 2 Fields
is selected,
while for the 2801–YE frame reset camera,
Interlaced, 1 Field
is
selected. In each case, the other selections are inactive (shaded type), and
cannot be selected. For non–standard cameras, the
V.Scan
mode
selection can be determined from the camera manufacturer’s
specifications.
•
Reset/Delay Mode –– This box selects the free running mode or one of
the reset/delay modes, according to the camera type in use. For the
2801–YC and –YD cameras,
Free Running
is selected, while for the
2801–YE frame reset camera,
Reset, Double Pulse VD
is selected. In
each case, the other selections are inactive (shaded type), and cannot be
selected. For non–standard cameras, the appropriate
Reset/Delay
mode
selection can be determined from the camera manufacturer’s
specifications.
