It's not semantics. I never played semantics. Maybe you confused DCR with Dynamic Lighting. Now Dynamic Lighting is a function.
And those picture are not of BLUR. They might be 'ghost' images, but it is not blur. If it was blur you would see the image 'smeared' from one point to the other. The only time you will see a snapshot of a blurred image is if it was recorded blurred.
You are so locked into the fact that you believe what you see. When you drive down the road and see trees rushing by they appear to be blurred unless you focus on a spot, even for a split second. Do the trees blur? No. Why? If you can answer why, then you will understand my argument. If not, I'll have to spend about 20 mins typing up an explanation for you. But with all the links you posted I'm surprised you haven't found it yet.
And it is not a strange concept to me because I understand far better than you do. I have 18 years experience with TVs.
