While there is clearly a sensor gap, this actually sounds like a huge and valuable application problem. DSLRs are not conventionally software extensible, while phones are...
The processing of dslr photos usually takes place outside the camera (raw conversion etc.), so my requirements for in-camera processing are quite small for a dslr. For my smartphone on the other hand I need pictures usable directly (typically).
Isn't that because DSLR manufacturers don't want people with an entry level phone getting the same software as the pro-sumer phone, or the pro-sumers upgrading software to the pro version?
