7.4 Zoom
The system supports two types of zoom:
Pan Zoom: enlarges a full image and pans the enlarged image to view the desired area.
Spot Zoom: focuses on processing the image of the selected area and enlarges the image with higher
resolution.
7.4.1. Pan Zoom
Pan Zoom is available on the live or frozen image in B mode and Color mode. There are 2 ways to
zoom an image: The <Zoom> paddle key or a pinch-out gesture on the trackpad.
Zoom Paddle key
o Press the upper part of the <Zoom>paddle to make the image bigger.
o Press the lower part of the <Zoom>paddle to make the image smaller, down to normal
size.
Pinch Gesture: Use two fingers on the main part of the trackpad, and move the two fingers
outward from each other (“Pinch-out”). The image will enlarge.
When in Pan Zoom mode, use the trackpad to pan the position of zoomed image, and the left bottom
corner of the display screen displays a live thumbnail of the full image with a green box on it indicating
the currently zoomed area.
The B image remains zoomed after entering other imaging modes.
7.4.2. Spot Zoom
Spot Zoom is only available on the live image in B mode and Color mode. To use Spot Zoom:
1. Press the middle part of <Zoom> paddle key, and a zoom box is displayed on the image.
2. Use trackpad to adjust the position and size of the zoom box. Press <Set> key to toggle between
moving the zoom box and adjusting the size.
3. Press the middle part of <Zoom> paddle key again to activate the Spot Zoom mode. The image
in the zoom box is enlarged and also the left bottom corner of the display screen displays a
thumbnail of the full image with a green zoom box on it indicating the currently zoomed area.
4. If needed, use the trackpad and <Set> key to adjust the position and size of the zoom box on the
thumbnail and view the enlarged image of other selected areas.
5. Press the upper part or lower part of the Zoom paddle to adjust the zoom factor which will be
displayed in real time in the parameter area.
6. Press the middle part of <Zoom> paddle key again to exit Spot Zoom.
The B image remains zoomed after entering other imaging modes
Note:
1. In Spot Zoom mode, the thumbnail image is not updated. It is the last image before Spot Zoom
mode was activated.
2. In Color mode, the Spot Zoom mode is activated when you first press the middle part of Zoom
paddle key, and the position of the zoom box is the same as the Color ROI box, but 10% bigger in
size. When the box size or box position is changed, the Color box and zoom box are adjusted so
that above relation remains constant.
3. The thumbnail image is only displayed in B mode and Color mode.
