Io non credo dipenda dal sensore di luminosità. Ero in una stanzina dedicata all'home theatre in un interrato di un centro hifi a luci spente... e anche se fosse i cambi repentini non mi sembrano una gran bella cosa.
comunque dalla recensione:
The short version is that, like most Plasma television displays we’ve tested, the light output of the TX-P42GT30 is not entirely stable and does sometimes shift mid-scene (or just at start of a scene). We used the same footage that we used to detect mid-scene brightness changes on the 2010 Panasonic plasmas (from the Se7en Blu-ray Disc) on the TX-P42GT30B, and at first, this Viera HDTV appeared to be free of any such quirks. However, in the next few shots, we detected a few examples of luminance shifting – the first being the close-up shot of tabloid newspaper headlines at the start of Chapter 6. When bodies moved past the camera, the gamma of the scene would shift in a single increment (that is, the change was instant, rather than gradual). The same thing happened a few frames in to the next shot, too. The good news, though, is that the [THX] picture mode was free of these subtle luminance shifts. We’re not sure what the reason for this is, though: is it pure luck (that is, the Gamma curve enforced by the THX mode is simply avoiding any problems), or have THX demanded that some sort of processing be bypassed for their approved picture mode? If it’s the latter, then Panasonic should re-think: the “Professional” modes should surely avoid as much processing as possible.
Quindi non mi pare di essermi sbagliato nell'accorgermi di questi sbalzi.
