  • EMC 3130 Lecture Three The Camera – Parts and Pieces Part 2: The Body Edward Bowen
  • The Camera Deconstructed http://science.discovery.com/videos/deconstructed-shorts- how-do-digital-cameras-use-light.html
  • Part 2: The Body The camera body contains the shutter, image sensor, the capture medium, support electronics, and control interfaces. Frame Rates (frames per second) Shutter Speed (fraction of a second)
  • Part 2: The Body The camera body contains the shutter, image sensor, the capture medium, support electronics, and control interfaces. Frame Rates The number of frames captured in a second (frames per second) Shutter Speed - The time light is allowed to strike the image sensor to create a single image. (fraction of a second)
  • Part 2: The Body The camera body contains the shutter, image sensor, the capture medium, support electronics, and control interfaces. Shutter Speed (fraction of a second) Generally, shutter speed must be at least half of the frame rate. At 30 frames per second, the shutter speed will be approximately 1/60th of a second. It can be faster if the camera allows. A higher frame rate requires a faster shutter speed. Shutter speed can be increased independent of the frame rate. A faster the shutter speed results in diminished blur A slower shutter speed results in added blur.
