You haven't given your argument as to why you think the Canon EOS10D performs better than the Lumia 1020, the OP asks if first gen DSLRs are worse than cell phone cameras, for the most part yes. IF you want to be pedantic and argue that it can't do everything the DSLR can then sure go ahead, but i'd much rather have a camera IN MY PHONE that is 90% of a camera that cost upwards of $3k back when it was on the market (only 11 years ago).
Sure that 10% matters to some people, but I seriously doubt the OP meant are cell phone cameras UNEQUIVOCALLY better than DSLRs and was more concerned with overall use in which case the cellphones overall are better than the DSLR.
And I think the only fair way to answer the OPs question is to say
In perfect conditions, the Lumia's sensor will provide better images. The further you divert from ideal, either through lighting or motion, the better the DSLR will look by comparison.
