Note: Because Netscape and Internet Explorer behave differently, the cameras operate two live
connection pages: a server push page for Netscape users and a Java Applet-based server
push page for Internet Explorer users. The cameras automatically sense the browser being
used and route users to the appropriate live connection page.
2.5.1 Pan/Tilt/Zoom Within Images
The Cohu 7100 Series Camera includes a digital scroll feature that allows moving around within
the full viewing area of the camera's imager. The following controls can be found at the top of
the View Images page:
zoom buttons Click the zoom buttons to zoom in (+) or out (-). The digital zoom
can be increased to an area that is two pixels wide. Once the zoom
feature is activated, the scroll (pan/tilt zoom) becomes usable (see
arrow buttons below). When the (-) zoom out reaches maximum
picture size, scrolling in either direction will show an alert message
indicating that the edge has been reached.
arrow buttons Click on the arrow buttons to move the image left, right, up, or
down, or scrolling the image. For each click, the center of view
will move by one-half the image size in the appropriate direction.
When the edge of the image is reached, an alert message will show
on the screen.
Note: Clicking within the image will also re-center the image to that area.
full image link Click the full image link to return quickly to the maximum image
size.
size buttons Click the size buttons to make the viewing window smaller (- ) or
larger (+). The maximum viewing window size is the same as the
camera's imager size. It can also downsample to progressively
smaller images that are 1/2, 1/4, 1/8, and 1/16 of the maximum
size. When the maximum or minimum image size is reached, an
alert message will show.
Note: At smaller sizes, image overlays will be truncated, and may overlap. The size of
the overlays do not change, but there is less image area available for displaying
them.
