Is Adaptive Tone Reproduction Equivalent To D-WDR ?

Andre Tournoux

Hi,

One of my Asian supplier market Effio-E (CXD4140) with D-WDR. Looking at Sony's website, I saw in the Effio E technical datasheet that there are no mentions to D-WDR or ATR being equivalent to D-WDR. I would like to know if I can assimilate ATR to D-WDR or if I should consider them as two distinct functions.

What is ATR supposed to be, exactly? I'm not familiar with that acronym. The datasheet you linked simply has a checkmark on the spec list indicating the chipset supports it, but doesn't state what it actually does...

Interesting... it appears to be a complementary function to WDR, as that second link indicates it's implemented alongside "true" double-shutter WDR in some cases. It looks like D-WDR, plus some extra image magic.

Here's an excerpt from another Sony Effio web page:

It appears to smooth out differences in shading and is a compliment to true WDR.
