Question 1

What does the gain control on an ENG/EFP camera compensate for electronically?&#10;A) very low light levels&#10;B) very high light levels&#10;C) dim colors&#10;D) too few pixels&#10;E) white-balance level

Accepted Answer

The gain control on an ENG/EFP camera is used to electronically boost the signal in low light conditions, allowing the camera to capture clearer images when there is insufficient light.

Question 2

Which statement best describes the basic video imaging process?&#10;A) the image is captured on film and developed by chemicals&#10;B) the light is converted to sound waves for recording&#10;C) the light waves are carried directly to the receiver&#10;D) the light is converted into electric energy&#10;E) the image is divided into subtractive colors

Accepted Answer

The basic video imaging process involves the conversion of light into electric energy, which is then processed and displayed on a screen. This is typically done through the use of a digital camera or sensor, which captures the light and converts it into a series of electrical signals. These signals are then transformed into digital data, which can be stored, manipulated, and displayed on a computer or other video device.

Question 3

What does picture resolution mean?&#10;A) the picture sequence resolves the story&#10;B) the electron beam scans every line from top to bottom&#10;C) the measurement of picture detail&#10;D) the picture composition&#10;E) the number of pixels on an image sensor

Accepted Answer

Picture resolution refers to the measurement of picture detail, typically described in terms of the number of pixels in the image.

Question 4

Which type of camera is self-contained?&#10;A) ENG&#10;B) studio cameras&#10;C) CCU&#10;D) CCD&#10;E) CMOS

Accepted Answer

ENG cameras are self-contained as they are designed to be portable and have all the necessary components integrated into one unit, including the camera, lens, microphone, and recording device. Studio cameras, on the other hand, require external equipment such as CCUs and control panels to function. CCD and CMOS are types of image sensors used in cameras, not types of cameras themselves.

Question 5

What are the four basic elements of a camera chain?&#10;A) camera, switcher, preview monitors, and CCU&#10;B) camera head, CCU, camera pedestal, and lens&#10;C) camera head, sync generator, power supply, and CCU&#10;D) power supply, pickup device, viewfinder, and camera head&#10;E) camera head, camera cable, video recorder, and CCU

Accepted Answer

The four basic elements of a camera chain are the camera head, sync generator, power supply, and camera control unit (CCU). These components work together to capture, synchronize, power, and control the camera's functions.

Question 6

What is a beam splitter?&#10;A) a prism that separates white light into RGB light colors&#10;B) part of the camera lens&#10;C) a filter on the camera light&#10;D) an electronic circuit that controls the scanning beam&#10;E) a device that lets a single electron beam scan all three primary light colors

Accepted Answer

A beam splitter is a prism that separates white light into the three primary colors: red, green, and blue. This is a common component in optical systems for imaging and display devices.

Question 7

In additive color mixing, which combination can result in white?&#10;A) red, blue, and yellow&#10;B) green, yellow, and white&#10;C) blue, red, and green&#10;D) red, green, and yellow&#10;E) magenta, yellow, and cyan

Accepted Answer

Blue, red, and green are the primary colors in additive color mixing. When combined in equal amounts, they produce white.

Question 8

What is contrast ratio?&#10;A) the ratio between pixels and resolution&#10;B) the ratio between the pickup device and the viewfinder&#10;C) the ratio between hue and saturation&#10;D) the ratio between luminance and chrominance&#10;E) the ratio between the brightest and darkest parts of the picture

Accepted Answer

Contrast ratio refers to the difference in light intensity between the brightest white and the darkest black a display or image can produce. It's a measure of the range of brightness levels a screen or projector can show, affecting the depth and detail visible in the picture.

Question 9

What does overcranking mean?&#10;A) recording at high frame rates for slow-motion playback&#10;B) recording at low frame rates for slow-motion playback&#10;C) recording at high frame rates for fast-motion playback&#10;D) recording at low frame rates for fast-motion playback&#10;E) recording at normal frame rates for normal playback

Accepted Answer

Overcranking refers to recording at a higher frame rate than the playback frame rate, which allows for slow-motion playback.

Question 10

What pair of connectors can be used for video?&#10;A) S-video and RCA phono&#10;B) XLR and RCA phono&#10;C) XLR and mini&#10;D) BNC and mini&#10;E) stereo phone plug and BNC

Accepted Answer

S-video and RCA phono are commonly used for video connections. XLR and mini connectors are typically used for audio. BNC connectors are primarily used in professional video and broadcast applications. Stereo phone plugs are typically used for audio connections, and are not recommended for video.
