With the lecture Media Technology, my aim is to cover the fundamentals of media technology, while providing students with the knowledge required to understand and work with advanced concepts and new phenomena in the field.

The focus is particularly on understanding the relationship between human perception and media technology as it exists today. This understanding is crucial for later consideration in the production of high quality digital media.

1. (Psycophyscial Aspects) of Visual Perception

  • Light as an electromagnetic wave
  • Spectral sensitivity, p (e.g., YUV 4:2:0).
  • Scotopic and Photopic Vision / brightness adaption
  • Peripheral Vision
  • Pixel Density / angular resolution
  • …

2. Camera Technology:

  • Pinhole Camera, SLR Camera, Mirorless Cameras
  • Optics (Focus)
  • Depth of Field
  • Aperture
  • Shutter Speed

3. Audio

  • Acustic (Frequency, Pitch, Tone, Noise)
  • Characteristics of the ear (Frequency Sensitiviy, Dynamic Range, Directional Hearing,..)
  • Sound Pressure Level
  • Sound transduction (Microphones)
  • Loudness war
  • Reverberation
  • Speakers (Stereo, DTS, …)
