Document Camera
 
Image of document camera
 

A document camera is similar to an overhead projector. Instead of using a lens to refract light onto the screen it uses a camera to transmit a video image to a Data Projector. Lights on the side are optimized for documents and objects. You may project an image of any three dimensional object onto the screen as instructional content. Your overhead projector transparancies will work fine with the document camera; if glare is a problem adjust the side lamps until the glare is minimized.

The basic controls for the Document Camera are located on the front panel of its base, as shown below. Some functions, such as lamp selection and powering on and off, are located on the touch screen, whereas the adjustment controls are located on the front panel:




T
o turn the power on , press "Select the DOC CAM" on the touchscreen of the console. A screen will appear with the options to "Power On," and "Power Off."

 


Simple controls on the base of the Document Camera adjust Zoom, Focus, and Iris (image brightness). These controls are shown on the above right image, and are on the right side of the front panel of the Document Camera. The camera focal length may be zoomed in to project an area as small as 1.5 by 1.75 inches or zoomed out to show an area of 10 by 12 inches. For optimum focus zoom all the way in to your object, focus, then zoom out to the desired frame size.
 
The Iris control varies the amount of light received by the camera and can affect the color and brightness of the projected image. Adjust the brightness to your preference while observing the projection screen.
 
The Document Camera has the ability to display your Overhead Projector Slides. Place the slide on the easel area as you would a normal document. Adjust the side lights to minimize any distracting glare.
 
Using the touch screen it is possible to illuminate the base lights for transpanancy projection. Your transparancies may appear washed-out and unreadable using the base lamps unless you adjust the Iris Control to a very low value.
 
When the "Select the DOC CAM" button is pressed the audio on the loudspeakers remains with whatever was the previous selection. You may mute this sound by pressing "Volume Control" and then touching the All Other "Mute" button.
