you heard it here first. my million dollar idea for this minute...

Why doesn't Pioneer [or someone] add $100 to the price and INCLUDE a little camera and program routine to auto calibrate the screen? Just suction it on the front and press go. moments later after flashing a few test screens, it's is setup to industry spec and can be used later in it's life or whenever the urge strikes.

It could even be wireless networked so you can move it around your room pointing it at the screen. Amplifiers do this now with setting up audio, no reason they can't do it for screens also.

Even better... embed the camera in the EDGE of the frame pointed at the screen. Could even set it up to auto calibrate for different ambient light levels - black the screen - lest the bright and color of ambient light, go back and calibrate.

a $120 camera to us is $7 in parts to the company, the software would take about 30 seconds of R&D [since it already exists in many forms] and it can be installed in the menu system like all the other features. Total cost per unit about $25 - jack the price up $100 or 200 for this FEATURE and we'll all come running! :D

So, Pioneer, or whoever steals my idea, you don't need to pay me or anything... I just want to make the world a better place. :)

I believe the Bang & Olufsen sets already do this. Rather expensive, though.

soneone correct me if I am wrong, and I very well may be...but doesn't pioneer's signature elite have some sort of an automatic calibration feature>?

Because the average viewer would not like a D65 calibrated picture. It's an acquired taste.

My PIO has a "light sensor" that can brighten or darken the overall picture, but it does not calibrate anything. I leave it off because it annoys me. :)

I would make the calibration compensate for users's poor taste. In other words, it [if the user left it turned on] would calibrate whatever MODE it was on
like if the user pulled up over bright, noxious white mode, the calibrator would at least keep the colors correct.

Or use can allow +3 amounts of "Excess" color to suit taste but the potential for accurate look is still there.

just some thoughts. Good feedback. :)

Yeah alot of people don't like d65. Even though i've never seen it, at first after i calibrated my set using calibration dvd's i did not like it.. but i got used to it and i cringe when i put it back to what i had it on. Honestly might look into ISF in the future.

I think that statement is a little strong. A lot of "average viewers" have found they like D65, even on first viewing.

Hardly a strong statement as that's what professional calibrators say. In fact, 2 notable calibrators here have said that the majority of their customers change the calibrated settings as soon as they leave.

I might not have the worlds most accurate calibration since I mainly copied someone elses settings and messed with them a bit but I can agree with most people not liking it. My entire family asked me what in the world I did to the TV the first time they saw it :eek:

Barco had something like that starting in the late '90s, but it was for convergence on their three-CRT FPTV and RPTV models. Barco said:

Barco developed the IRIS 800 a fully automatic convergence system for Barco's CRT based projection systems. Using the IRIS 800's user-friendly on-screen displays, the unit effortlessly aligns the projected image on the screen faster and more accurately then ever before possible through the conventional 'manual' convergence process. The special mechanical fixing system makes it possible to use the IRIS 800 as a stand-alone unit in conjunction with a tripod, for Barco's retro projectors and rear-screen installations.

I understand what people say but it is all anecdotal. You can't simply say the "average viewer" or "most" or whatever based on anecdotes. That's what bothered me about the statement. Generalizations are only valid if you can back them up and that takes more than just a few opinions.

When professional calibrators say it then it's more than anecdotal. It becomes expert opinion

Yeah, my $500 Electrohome CRT projector had a little camera that attempted to view and adjust the convergence pattern. Generally OK but you always went in after and touched things up...

Yes, the Bang and Olufsens do http://www.bang-olufsen.com/page.asp?id=578. Not sure how well it works, but I assume it better for the price tag. The signature series do NOT. I would love for someone to get their hands on one of these and take measurements with this system :D

there, see? it works and appears usable. Now, if the big boys would put it into their TVs, just like they do with their audio gear that is self tuning, we'd be all set. It only makes sense.

The question is will the customer pay extra for it? I say no. The average consumer is only concerned with wringing every last cent out of their purchase price and a manufacturer would have to prove to the consumers that this feature is worth $XXX more. The average consumer has never heard of the term calibration in reference to their plasma.

Well, AVR's used to need to be manually calibrated. Now they have a microphone and auto settings to do the work. I don't see why this shouldn't become common with TV's.

What I would like to see is a calibration disc like DVE that can diagnose the peculiarity of a display device given the player selected and then display the optimum settings required for all the parameters relevant to be fine tuned for a near ideal picture ( contrast, brightness, color, sharpness, etc.). This would really make calibration a no brainer!:)

Your $500 Electrohome projector was >$15k when it was new. At $500, companies don't develop servo-driven robotic CCD cameras. And the camera system cost more than a 50" plasma does today. ;) (Ah, ACON...)

interesting. roll with that.... do you mean like a DVE disk custom designed for YOUR TV model as a pack in from the manufacturer or something? I guess they could have one DVD with test patterns AND a huge data base of TV "BEST OF" settings from pro tuners or TweakTV or similar

I did like the AVSHD 709 test disc and felt it was even more accurate than DVE's for a poor man's calibration. but they could dumb it down even more for the end user, into like a 4 step process... "Can you see THIS black box? Done. goto step 2" etc

or how about this: WHY DON'T THEY CALIBRATE IT AT THE FACTORY?? They could research it, and figure out what numbers it should be at post break in. Yes, it coudl be off a smidge, but still. Just a thought

The problem with this idea has always been whether the set would hold the settings through shipping, handling by who knows who, etc. and still maintain its settings.

I think they could get a reasonably good calibration at the factory. Most TVs are off because they have horrible color decoder errors, drastically bad gamma, extremely cool color temps, incorrect color gamuts, etc. That stuff could all be done correctly at the factory with little to no effort. If you really wanted that last 1% to 5% improvement, you could get it calibrated.
