Captures a shot of the video picture from a single channel and
saves it as a JPEG file. The size of the output image is 640 X 480
pixels for NTSC and 768 X 576 for PAL signals.
To use the video capture feature, in the System
Settings window's [Image Unit] page, [enable] the [Video Control
Start Address]. In the defined video address, turn ON bit 4 to
initiate the video capture.
To save video captures to the CF card, from the
[System Settings] window's [Display Unit], click the [Mode] tab and
clear the [Capture Action] check box. If the check box is selected,
video is stored in the defined destination.
Captured Channel
Select the channel to capture.
JPG file number
In the [System Settings] window, select [Display Unit] and click
the [Mode] tab. From [Screen Capture], select the [Capture Action]
check box. For [Save in], when you select [FTP Server] option, this
setting is disabled. In this case, the file number becomes a time
stamp (year, month, day, hours, minutes, seconds).
Direct
Set a number to be the JPEG file name. The setting range is from
0 to 65535.
The saved file name is "CPXXXXX.JPG" (XXXXX is the specified
value). The file will be stored in the CF card's "CAPTURE"
folder.
The file is always saved using the file name
defined here. If a file with the same name already exists in the
destination, that file will be overwritten.
Indirect
Stores the file number to : [Video Control Address] + 2
specified in the system settings [Image Unit] settings.
For any destination other than the FTP server,
you can add and delete file numbers by using the [Auto Increment
File Number] option, available from the [System Settings] window's
[Display Unit], in the [Mode] tab's [Screen Capture] area.
