ENHANCEMENT
TOOLS
Use the image enhancement tools screen to enhance an image from
the image database or from the restored images database. Adjust
the brightness, contrast, balance, color and sharpness of the image.
NOTE: Image enhancement is a protected feature. You must
possess the Playback Enable privilege to access it (see
Security Setup on page 39).
NOTE: Enhancements do not affect the original image.
Image Area — The image area displays the selected image,
including all enhancements.
As you zoom in and out, the unit displays the level of magnification:
1:1, 2:1, 4:1, 8:1, 16:1. Use Zoom In to magnify an area of the image.
The pointer becomes a magnifying glass with a plus sign. Click
anywhere on the image. The area around the pointer is magnified
and the magnified image is centered where you clicked. Each click
magnifies the image to the next magnification: 2:1, 4:1, 8:1, 16:1.
Otherwise, click and drag the pointer to draw a box around a
specific area. Release the mouse button. The unit magnifies the
selected area to the nearest magnification: 2:1, 4:1, 8:1, 16:1.
NOTE: An image cannot be magnified beyond 16:1.
Use Zoom Out to display a wider view of the magnified portion of
the image. The pointer becomes a magnifying glass with a minus
sign. To zoom out, click anywhere on the image. A wider view is
displayed, centered on the point where you clicked. Each click
displays more of the image and reduces the image detail one level.
Clicking the mouse pointer has no effect once the image is
displayed at its original size.
Move — Use this option to view a different area of the image when
magnified. The pointer becomes a four-direction arrow.
1. Click and drag the image to the right, left, up, down or
diagonally.
2. Release the mouse button when the desired portion of the
image appears.
Enhance — Use this option to enhance the image when zooming.
As an image is enlarged, it becomes jagged. This feature reduces
jaggedness. The brightness chart (if displayed) also reflects the
changes.
