Tips

There are various models of document cameras in classrooms. Some of these tips may not apply to the device in your room.

  • Depending on which type of item you plan to display, use the "LAMP" button to adjust the light source accordingly. Each time you press the button, it cycles through these settings: upper lamps on, lightbox on, and all lightings off.
  • When using transparencies or slides, change the light source to "lightbox on" (this will backlight the object from the white box in the center of the document camera).
  • When using three-dimensional or opaque objects, change the light source to "upper lamps on." Be sure to adjust the lamps so the light is directed at the object.
  • If the image color or brightness is imbalanced, automatically adjust the color by placing a white piece of paper under the lens and pressing the Auto White Correction (AWC) or Auto White Balance (AWB) button.
  • Use the Iris buttons on the document camera to adjust brightness.
  • Use the Detail button to control image sharpness. Text usually benefits from a detail setting of "High." Images may appear distorted when using the "High" setting.
  • If the image is blurry:
    • Use the "APERTURE" button to control image sharpness. For images with mostly text, turn the aperture ON. For images with many pictures or colors, turn aperture OFF.
    • Use the "AF" or "Auto-Focus" button to automatically focus the image.
    • Use the Zoom, Wide, or Tele buttons to enlarge or reduce image size
  • rotateIf the image is rotated on the Samsung SDP-860 models, you can correct the rotation by trying the following:
    • Rotate or flip the camera arm or head to turn in the opposite direction of the current position. It may reverse the image.
    • Use the settings by pressing the buttons on the document camera base to adjust the image by 180°. Use the following procedure for this option:
      • Press the center button inside the large circular button. After pressing, a set of options will appear on the projection screen (make sure document camera source is selected). In the first set of options, select Image Adjustment. Move to this option, by pressing the button by the down arrow, then the middle button to select.
      • In the second set of options, select Rotation. Change 0 to 180 (or 180 to 0) by selecting one of the buttons by the side arrows.
      • When finished, select Return. Then, Save and Exit.
