==Examples of Taking Advantage of the HVS==

* [[Flicker fusion threshold | Flicker frequency of film and television using persistence of vision to fool viewer into seeing a continuous image]]

* Colour television (chrominance at half resolution of luminance)

* [[Interlacing | Interlaced television]] painting half images to give the impression of a higher flicker frequency

* Image compression (higher frequencies more harshly quantised)

* Colour television (chrominance at half resolution of luminance corresponding to proportions of rods and cones in eye)

* Image compression (difficult to see higher frequencies more harshly quantised)

* [[Motion estimation]] (use luminance and ignore colour)
