OK, I'm happy with "peaking", it's edge detection and highlighting - a common signal processing technique in image processing. It won't do the foreground/background thing though.

yes, "peaking" is a component of visionclear...

but it is boundary modification for adjoining areas of color and contrast.

it has nothing to do with delineating between foreground and background and refocusing them to suit...

happy holidays, too!

i think its refered to as peaking.

anyway this is getting boring.

Have a merry Christmas

...no mention of "re-focusing" foreground and background.

i think you are reading too much into visionclear!

Dude1:
my sincerest apologies.
BangVisions do process foreground information differently to background, in most circumstances to varying degrees. They have a hard time doing this on a shot of a football ground for example, as nothing is determined to be of more importance in the shot. They do this more when there is an object that is dominant in the shot.
Processors do this by assessing information that is most relevant to the picture then "cutting" and highlights aspects of the picture by adding contrast ratios etc to add depth to the picture. It is simply demonstrated, by viewing one. The Avant and BV7-40 are good demonstrators of this, of course this has been improved over time so naturally it is not as prevelant in older sets.

i, for one, would love a reference to the technical data supporting this...

bayerische:
However, that the contrast screen would blur the image not in focus is impossible. The contrast screen is a total "dummy". Blurring of the background is only done with the camera lenses aperture, and if the contrast screen was to blur the image, it would blur the whole image and not just the parts that are out of focus or background.

bingo, bango, bongo... i agree!

in simplest terms... "depth of field" and its relative focus is completely driven by the lens aperture at the time of the shot (photo or video)...

I do know it to be true.
I measure quality of picture with my eyes.

With respect, the picture quality wasn't what I questioned, it was your claim the B&O TV's can somehow process foreground information differently to background.

That is true, but the image reproduction on BangVisions using VisionClear technology has been designed so the image at the very front of the screen - say for example a person walking is far clearer and focused and the scenery behind that person is slightly less focused. This and good use of contrast and colour give a almost 3d image to the picture quality. No, the image is not out of the screen - but far better reproduced than most other manufacturers - check Avant / BV7-40.

Do you know this to be true? - this seems too good to be true. How do you determine depth of field in a 2D image, even if something is moving how can you tell if it is an eagle in the distance or a housefly on the camera lens?

I can understand dynamic control of colours, luminence, contrast and edge detection/sharpening etc. but what you describe seems incredible, especially in an analogue TV signal without a frame store.

FWIW, we've just bought a Samsung 32" LCD to go in our lounge. The simple reason is that we can't afford a BeoVision, but for those who can, it highlights just where the price goes in a B&O TV. The Samsungs seemed to be the best performers, but they're still miles off the picture of a BeoVision. The difference seems to be even larger towards the larger-sized TVs.

VisionClear encompasses everything which produces the image on a B&O Television, from the Anti-Reflection Contrast panel in front of the display to the processing which sits behind it. The only way you can really appreciate the picture on a B&O TV is to get used to the picture they produce (as I have done) and then look at the brand-X offerings.

This is without even talking about the sound, integration or design/build quality.
