Is Adaptive Tone Reproduction Equivalent To D-WDR ?

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.

Regards,

AL
