High Definition Images

Welcome to the next in our series of technology articles. This next one is actually one of my favorites as the dissemination of visual information is a key to many of simulation routines. Anyway, way back in 1988 I was looking at image reproduction and graphical progression. It is an interesting topic as it is much easier than logic circuits. You can acually fake a lot of the facets of images repro.

For example, from a distance perception of images starts to change and by the same token, proximity can also cause perception aberrations. SOme people see better from far and some see better closer. Also, the amount of absorbed and refracted light can change this perception even more.

When looking at the various methodologies used one can see that sometimes Technicolor outshines ILM. After lookig at the various types of surface that can be used to "imprint" digital or ananlog signals representing images, the most efficient for reuse seems to be Au. Modeling CrO tapes and 8mm film, one can see that the adherence factor of the material to its base is a very important factor.

Of course, another major obstale is the "imprint" method. The CCD method uses a series of transceiver devices to record more than just the amount of light. By using PID tech it becomes possible to record luminance, chrominance, etc in the same data stream. This enables digital manipualiton by allowing each stream to be adjusted there by changing or "editing" the picture.

Multiple pictures can then be sequenced and displayed in order which actually creates video. ANother breakthrough was the use of colored lenses and high energy light. By tuning the base frequency of the imprint material it is possible to actually reject any frequency of light or increase either of the underlying streams. Physicists have recently found that intense fields can even deflect light. Using phase angular field gemeration it is even possible to "morph" objects merely by adjusting various fields in the vector space.

This enables even greater flexibilty in editing.

Oh well, gotta go.
