This guide provides basic information about installing and using Applied

VisionTM 4 Software. You can also find this guide on the Ken-A-Vision® web

site www.ken-a-vision.com/resources.

Introduction to Applied VisionTM Software

Applied Vision 4 (AV4) is a software program designed to enhance the use of

Ken-A-Vision digital imaging products.

Applied Vision enables users to connect their USB-based Ken-A-Vision

products to their computer, allowing capturing, viewing, and manipulation of

both video and still images. Applied Vision 4 is optimized for utilization in a

classroom setting while remaining widely applicable for any environment in

which digital imaging is required.

Here are a few of the features built into Applied Vision:

• Cross-platform support for Windows, Mac, and Linux

• Full screen viewing

• Video recording

• Still image capture

• Multiple camera support

• Advanced image editing and analysis

• Time lapse recording

• Video rotation

• Digitalzoom

• Numerous science applications including calibrated measurement

Installation

Minimum Requirements

o Windows XP SP2 or higher, Windows Vista

o 512MB RAM

o USB 2.0

Installation Instructions

Insert the software disc into your disc drive, and the installer will launch via

AutoPlay. If your camera requires drivers, it will choose to install these by

default as well. Follow the prompts, and at the end if you are prompted to

reboot, do so. When finished, plug in your camera; depending on the model,

it may automatically install the driver in a matter of seconds, or a "Found New

Hardware" wizard may appear. If the latter, click through the default selections

to automatically install the device drivers for your camera.

Automatic Updates

Applied Vision 4 has an automatic update feature that will query Ken-A-Vision

for newer versions of the software. You can adjust the settings or operate this

update checker manually with options in the Help menu.

Applied Vision 3 Software

Temporarily we are including, for your convenience, our previous software

Applied Vision 3 (AV3) for those who prefer its simpler functions and interface.

The installer file can be accessed by browsing the "AV3" folder on the CD and

running AV3Install.exe stored in that directory.

Mac Software

If your camera is a model that is compatible with Mac OSX, we have included

a "Mac Software" directory on your software disc from which you can install

Ken-A-Vision Capture 1.3.2, our current imaging software for OSX. Check

our website (http://www.ken-a-vision.com) frequently for the upcoming release

of Applied Vision 4 for Mac OSX which will bring the advanced features of

Applied Vision to the Mac platform.

Interface Description

Applied Vision 4 creates a unique window for each active video device and

each captured image or movie.

There are three styles of windows:

Camera Window - Live streaming video from the USB camera device.

Image Window - A still image captured from the video stream or loaded

from a saved file.

Video Window - A movie captured from the camera or loaded from a saved

file.

When Applied Vision launches, the primary window opens, and then camera

windows are opened for any available imaging devices.

Main Applied Vision Window

The main Applied Vision window is the parent window for the application. If

you close this window, it will close all Applied Vision windows and the

application.

At the top of the window is a menu bar:

• File

o Properties - Set various program properties such as the localized

language of choice

o Exit - Exit the Applied Vision application

o A dynamically populated list of all available imaging devices on

your system

o Refresh Device List

• Snapshots

which allows the user to layer one image over another

Camera Window

The Camera Window displays the real-time live video stream being transmitted

by the connected video device. It may be resized, moved, maximized,

minimized, or closed.

At the bottom of the window is a tabbed toolbar. It has four tabs:

• Camera Options (default)

•Rotate

•ColorBalance

This toolbar is the default toolbar setting of a Camera window. The following

commonly used features are included:

mode, click the "X" button in the upper right corner of the screen.

• Take Snapshot - Capture a still image frame from the video stream,

and open the captured image up in a new Image window.

• Record - Select a location and filename to record to, and start

capturing video to a saved movie file. Click the button again to stop the

recording process.

• Time-Lapse Record - Enter a time value in seconds and then select a

location to save the files. Applied Vision 4 will take a snapshot once

every number of seconds specified by the user.

• Document Orientation - Flip and mirrors the current video. Useful

when documents are placed under the camera and appear "upside

down".

• Camera Resolution - Change the display resolution of the camera.

High resolutions have superior image quality but lower frame rates.

Lower resolutions have superior frame rates but lower image quality.

Camera: Rotate Toolbar

This toolbar offers several options for rotating and manipulating the video

stream:

This toolbar allows adjustment of the following settings affecting the video

stream:

Camera: Zoom Toolbar

This toolbar allows digital zooming on the video stream. There are three

modes:

•Original Size - Display video without scaling.

•Fit to Window - Scale the image to fit in the window size; this is the

default.

•Custom Zoom - Allow for a manual configuration of digital zooming.

When Custom Zoom is enabled, the slider bar at right can be utilized to

change the zoom factor. Note, that as digital zoom increases, the image will

progressively pixelate. To return to normal settings, click Fit to Window.

Image Window

The image window displays a still image captured from a video device or

opened from a file. It may be resized, moved, maximized, minimized, or

closed. At the bottom of the window is a tabbed toolbar. It has six tabs:

• General (default)

unsaved, Save Image As).

• Save Image As - Save the image with a specified filename and

location.

Image: Measure Toolbar

This toolbar provides the following tools for measurement and analysis:

•Measurement Type

o Linear Measurement - Measure a straight line.

o Angular Measurement - Measure an angle.

•Calibration - Create a new scale measurement standard.

•Select/Remove Scale

o Select Saved Scales - Choose a saved scale with which to measure.

o Remove Saved Scales - Remove a previously saved scale.

•Perform Measurement - Show the results of the current measurement

relative to the selected scale.

•Copy All Measurements to Clipboard - Add contents of the Mea-

surement window to the clipboard for pasting into other programs.

Calibration

To calibrate a new scale, follow these instructions:

1. First ensure Measurement Type is set to Linear Measurement.

2. Click Calibration

a. If an existing line is on the image, Applied Vision 4 will prompt you

to either use the existing line or draw a new one for the purpose of

identifying a known distance that can be used to calibrate a

measurement scale. Multiple measurement scales are useful

when measuring objects viewed through a microscope under

different objectives.

3. Type a full name for the scale under Name.

4. The Distance in Pixels should be preset according to the line drawn in

step 2.

5. Type the amount of actual units measured by the line in Known

Distance.

6. Enter an abbreviated unit name under Unit of Length.

7. Click OK.

Now the new scale will be selected by default and new measurements will be

computed using that scale.
