1. _______________ With the lens set at infinity, the distance from the iris to the plane where the picture is
in focus. Normally it is measured in millimeters or inches.
2. _______________The scale on the lens, indicating the aperture. The larger the ƒ-stop number, the smaller
the aperture; the smaller the ƒ-stop number, the larger the aperture.
3. ________________Adjustable lens-opening mechanism. Also called lens diaphragm.
4. ________________ Contains the black-and-white part of a video signal. It is mainly responsible for the
sharpness of the picture. Also called luma, or Y, channel.
5. ________________ A lens that permits a relatively small amount of light to pass through (relatively high ƒstop number at its largest aperture). Requires higher light levels for optimal pictures.
6. _________________A small video screen or fl at-panel display on a camera that shows the black-andwhite or color picture the camera generates. The fl at-panel displays are also called monitors.
7. _________________ Variable-focal-length lens. All video cameras are equipped with a zoom lens.
8. _________________ How much the focal length can be changed from a wide shot to a close-up during a
zoom. The zoom range is stated as a ratio, such as 20:1. Also called zoom ratio.
9. ________________Iris opening of a lens; usually measured in ƒ-stops.
10. ________________ Optical device within the camera that splits the white light into the three additive
primary light colors: red, green, and blue.
11. _________________A portable camera with the video recorder built into it.
12. _________________ The camera and the associated electronic equipment, consisting of the power supply,
the sync generator, and the camera control unit.
13. _________________ Equipment, separate from the actual camera, that allows the video operator to
adjust the color and brightness balance before and during the production.
14. _________________ A solid-state imaging device that translates the optical image into a video signal. Also
called chip.
15. _________________Contains the RGB video signals or some combination thereof. Also called color, or C,
channel.
16. _________________ Highly portable, high-end self-contained camera for electronic field production.
17. __________________A lens that permits a relatively great amount of light to pass through at its largest
aperture (lowest ƒ-stop number). Can be used in low-light conditions.
