COM 316 / COM316 EXAM 2 LATEST GENDER AND
COMMUNICATION QUESTIONS AND CORRECT
ANSWERS
CCD Sensors - ANSWER: Charged coupled device
global shutter, all pixels are exposed and read at the same moment, the image is
held and read row by row
vertical smear is possible - analog device
CMOS Sensors - ANSWER: Complementary Metal-Oxide Semiconductor
contains a sampling capacitor, an amplifying transitor, and all of the readout timing
circuitry for converting light energy into an amplified electronic signal
read one horizontal row of pixels at a time, creates a complete frame
fast, energy effiecent
Difference between CMOS and CCD - ANSWER: CMOS are the wave of the future and
what are put in cameras modern day - CCD doesn't allow for as many frames per
second
Digital signal processor - ANSWER: microprocessors that use an algorithm to process
information
Image and video enhancement
Video noise reduction
Video stabilization
Video object tracking
most complex part of camera
True or false, DSP has one standard algorithm - ANSWER: false, they work with
algorithms specific to the camera's format (AVCHD, XDCAM HD, Sony XAVC, Canon
XF, REDCODE, etc.)
Demosaicing - ANSWER: DSP combing three sets of information (RGB) from ADCs,
determines brightness and color value of every pixel in every frame
Interlaced Scanning - ANSWER: Creates a frame by making two fields, each lasting for
1/60th of a second
outputs odd-numbered horizontal pixel lines one at a time, top to bottom
, Progressive Scanning - ANSWER: Sensor reads out the full frame, all horizontal lines
in order from top to bottom
Interlaced v Progressive Scanning - ANSWER: Progressive scan displays each frame
sequentially and provides superior image clarity, ideal for streaming services and
HDTV due to its smooth, artifact-free images.
Interlaced scan splits frames into alternating fields and conserves bandwidth,
suitable for traditional broadcast television and older video formats.
Frame rates - ANSWER: the measurement of how quickly a number of frames
appears within a second
standard frame rate 24fps.
More frames per second for slow motion, less for sped up scenes
Aspect Ratio - ANSWER: how tall/wide things were
In the beginning, ratio was 1.33:1 (4x3) film and tv (40s-50s)
Film uses 1.33:1, tv uses 4x3
In the 60s, film changed to compete with TV
developed 1.85:1 and 2.35:1
Compression - ANSWER: Our cameras, for example shoot in AVCHD (which is
H.264/MPEG 4 format also called AVC)
MPEG 4 is the universal format
Resolution - ANSWER: the ability to resolve fine details. The more pixels a display
uses to render pictures, the finer the detail
Parts/Functions of the Camera - ANSWER: Power switch, magnification, peaking,
zebra, AF lock, status, white balance buttons, neutral density filter, auto iris,
ISO/gain, shutter
Power switch - ANSWER: has camera and media functions
magnification - ANSWER: zoom and focus (doesn't actually zoom) (8 on cam)
Peaking - ANSWER: number 9 on cam, takes image, gives contrast for crisp focus
Zebra - ANSWER: number 10, shows exposure. makes sure there is no over or
underexposure on image
AF lock - ANSWER: number 11, auto focus lock
