Zoom

The system supports three 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.

Full Screen Zoom: enlarges the image to full screen display.

7.4.1. Pan Zoom

Pan Zoom is available on the live or frozen image in B mode and Color mode. Rotate the physical

<Zoom> knob on console to zoom an image.

 Zoom Knob

o Turn the Zoom knob rightwards to make the image bigger.

o Turn the Zoom knob leftwards to make the image smaller, down to normal size.

When in Pan Zoom mode, use the trackball 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.

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 <Zoom> knob, and a zoom box is displayed on the image.

2. Use trackball 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 <Zoom> knob 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 trackball 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. Turn the <Zoom> knob rightwards or leftwards to adjust the zoom factor which will be displayed

in real time in the parameter area.

6. Press the <Zoom> knob again to exit Spot Zoom.

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 Zoom knob, 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.
