Crop Tab
Use the Crop tab to personalize the size of your camera image. Cropping involves
discarding all but a selected region of interest in the camera image. This smaller image
may increase your frame rate.
Press:
• Apply to set your camera to use the crop settings currently shown on the page.
• Default to remove cropping from your image.
• Cancel to restore this page's crop settings to the state they were in when you
entered the page.
You can also use your mouse to crop (see step 2 on page 25 ).
Note When you crop an image, the maximum frame rate increases. See Frame
Rate (NTSC/PAL) on page 46 .
Exposure Tab
Use the Exposure tab to set the part of the image used for automatic exposure (gain)
calculations.
Figure 1-10 Exposure Tab
You can select a rectangular region of interest where brightness and color balance are
optimized. This is useful if parts of your image are excessively bright or dark (for example,
if your image contains large amounts of sky or sunlit windows). However, setting an
exposure window may darken or brighten other areas of your image.
Click apply to have your settings take effect.
For best color balance, use an exposure window containing at least 20,000 pixels—200
by 100—and try to include some gray or white areas.
Figure 1-11 shows the current exposure area outlined in blue.
