Discussion in 'Plasma TVs' started by Chavvychase, Jul 28, 2005.
I have seen this word on various threads but I have never ween it defined. What is it?
Chavvychase - since you've recently bought the Samsung plasma which I've been considering, should I be concerned that you are asking this question??!!
Solarisation is a reversal of 'tone' in the image.
ie. What should be dark areas appear light and light areas appear dark.
On most forums when people are talking about 'Solarisation' they really mean 'Posterisation', this is when what should be a smooth gradual change from one colour to another, actually changes in a series of obvious steps.
Well, perhaps. I've never claimed to be an expert on plasmas. I have not noticed solarisation on my 5H, but perhaps thats because I have not been looking for it.
The main thing i have noticed on my Sammy 5h is in say dark brown sceens like veneered table or staircase the brown looks blocky and you can see the blocks moving if you look real hard i think its signal related and prob just down to the Telewest feed and my cheapo Tesco Dansai dvd player
That is macroblocking isn't it?
This is what people generally mean I think...
Take and image that is nice and smooth
and some displays give an image like this (obviously made to look far worse than you would normally see)
Some people also call solorisation the effect you get when you see like a ghosting in red, green and blue, usually when say a well lit face is against a dark background and it moves quickly.
So you have to be careful when people describe stuff in technical terms as they may not have got the name quite right.
Far better examples than I managed to knock up!
Separate names with a comma.
