If you optimize your content properly, you should be able to rank all of those keywords with 1 page (with great content and links). Those keywords are semantically the same. Hummingbird is a awesome if you know how to leverage it.
One trick is to use parentheses. For example, your opening sentence could be "ImageCo is the world leader in Device Imagery Software (DIS) Solutions."
I would use "DIS Software" and "DIS Solutions" a few times in the document, and I would place those keywords in close proximity to the non-abbreviated keywords so Google links them semantically. I would also use all 3 Keywords in their own H2s.
The trick is not to overdo it and make it look natural. No need to spam it.
I would also be mixing in Proof Terms and Relevant Terms throughout the document with the most important going in the first 2 paragraphs.
For a title tag, I would use:
Device Imagery Software | DIS Solutions | Company Name
It's much easier and cheaper to write 1 page of killer content and build links to it than to build 3.
