100 Hz : an even closer look!
We see that in the car test, the processor adds images between the two sent by the source. This is rather easy in the common case of a fixed object in lateral motion. In a game or movie, most images are minor modifications of the previous one. The test in the previous page represents what happens in most transitions. But what would happen if the T+1 image is radically different. What would the processor do? Would it really calculate, as Samsung says, an intermediate image?
To see this, we created a few scenes in which objects change shape or position every 20 ms. At 50 Hz, each new image is radically different from the previous one. For example, one of our sequences represents a simple triangle that spins, moves from left to right and changes color. In one step it turns from green to blue. Most of the time, here is the result:
Green and then blue, the triangles are well distinguished, and then the processor fails in the image calculation. Sometimes, it doesn´t add anything and our sequences indicate the same thing as soon as two consecutive scenes show strong disparities. At other times it does, however, and the image look like this: 
The "intermediate" image is very approximate, and we could even say that it is a complete miss.
We had the same observations for another sequence, this time after changing a square into a triangle:
There isn´t necessarily an image added between the two received, but this isn´t systematic. If the processor isn´t powerful enough to calculate real complex intermediate images, it doesn´t try if it is too complicated. These are obviously the first steps in this domain and this is the first time that we could test such a system. Either way, the first results are very impressive and encouraging.
After verification, our impressions were justified. The calculation of the intermediate image is based on a vectorization of the area of the image, cut out into 8 x 8 pixel squares:
It is normal that for now we saw real changes only on objects that only go though minor changes without strong deformations.
