Which Canon (or different brand) camera is the best for this?

I just started using my iPhone 5 camera quite a bit nowadays. On my iPhone I'm able to tap on the screen to focus on an image in the background and have the picture focused on that and the other way around. Obviously I'd like to have it a much better quality so if I decide to print it and/or upload it on a site it'll look much better and detailed. I was thinking about some of these:
Canon Elph 115 IS (IXUS 132 HS)
Canon PowerShot A1400
Canon PowerShot A2500

Or it could be a different brand. I just want something that takes good quality photos and that can focus on the foreground or background whenever I want it to.

Here's what I mean:
Focused in front:
image

Focused in background:
image
image

Also, would it be possible to send the file to someone who would be able to put it on a larger scale so it can be in a larger frame? Or would that require a more expensive camera?

Thank you for clearing up focus in front and focus in background. That surely made things easier here to understand. Upon seeing those sample shots, here are what I recommend.

Get a camera like this ( http://www.bhphotovideo.com/..._With.html ) then study photography to get focus right.

The Canon 1D X is beautiful but very expensive. Anyways, I love it and its just amazing is every way. It focuses fast and well it's the top Canon camera out there. Canon has a system with their digits. The 1D X has one digit. That's the top class. The second best class has 2 digits, then 3, and so on. Go for a Canon for sure. Whatever grade or level you go for, Canon has really good cameras, and they're cheaper than Nikon.
