Zoom Out
When you click on the "Zoom Out" button one time, the image size in the
display area will be minified 12.5 percent to the original size. To show the
location and time information completely, the minimum zoom out ratio is
limited in 0.5:1.
Full Screen
When you click on the Full Screen button, the video sequence will be
enlarged to fill the whole screen. You can double click on any place to return
to the original state. When you switch to full screen display, you can press
the "Alt" and "Space" keys together to pop the jog dial to control the
displaying video sequence. Press the same keys again will close the jog dial.
You can also press the "Alt" and "Enter" keys together to switch between the
normal display and full screen display at any time when the program is under
the normal display mode.
Searching Range Adjustment Toolbox
The Searching Range Adjustment Toolbox provides you a faster way to
change the range of the displayed time period. By using this toolbox, you can
browse the database of one location from any 10-second interval over its entire
range. Below is the Searching Range Adjustment Toolbox with its own three
elements: "Zoom In", "Zoom Out", and "Full Range".
Zoom In
Each time you click on the "Zoom In" button in the searching range
adjustment toolbox, the displayed time period will be half in the center of the
original time period until the period is equal to 10 seconds. You can see the
new interval in more details. The scale of pull bar and alert histogram window
changes and the period start and end time change, too. The period selector
will show the new start and end time. And the display area will restart to
display the new period from the new start time.
