Capture Settings Dialog
This dialog gives the user complete control over image storage.
Figure 9 – Capture Settings dialog
Start/Stop
This button will toggle between
‘Start Capture’
and
‘Stop Capture’
Capture
every time the user clicks on it. Clicking on ‘Start Capture‘ starts the
process of recording the images to disk. The options set in the ‘Capture
Options’ field determine what, how and when actual recording is
performed. Clicking on ‘Stop Capture’ causes recording to stop.
Close
This button will hide the Capture Settings Dialog screen. You can
invoke it again by either hitting Ctrl-S or by selecting it from the Control
Panel pull-down menu.
Image Format
When recording images to disk, this option selects the format, ‘BMP’,
‘JPEG’, ‘TIFF’ or ‘RAW’, that the image will be saved in. Selecting
‘JPEG’ activates a compression slider. ‘Best’ provides the least
compression, while ‘Small’ provides the most compression.
Normalize
Normalize defines the way in which TIFF files are created. Since a
TIFF file uses 16 bits to represent each pixel and cameras can produce less
than 16 bit pixels, the normalize option is provided. If ‘normalize’ is
disabled, then left pixel padding is used so that 16 bit TIFF data is
produced by appending zeros to the MSB bits of the pixel data. For
example, for a 10 bit pixel the resultant 16 bit TIFF data is
“0,0,0,0,0,0,p10, p9….p2,p1” where p10..p1 represent the 10 bit pixel.
Left padding is useful when the user wishes to post-process the TIFF data.
