Sir, your usage demands quality though may be little chunkier, you require DSLR.
(Traditionally, the only real options for digital photographers have either been compact cameras which have very small image sensors, or the considerably larger - in both sensor and body dimensions - DSLR designs. DSLR sensor is almost 10 times bigger than conventional point & shoot cameras, hence exceptional low-light image quality & greater control over depth-of-field.)
Now in DSLR, there are conventional DSLRs & Mirrorless DSLRs. Advantages of later is
a) significantly smaller camera that combines DSLR image quality with a more compact-camera-like user experience
b) traditionally digital compact offer a fast, live preview of the scene you're shooting on the rear display - often called 'live view', while DSLR are slow at that. But mirrorless dslr are little faster for "live view" than traditional DSLRs.
c) don't need to raise the camera to eye-level to take a photograph
d) Almost all compact cameras use contrast-detection autofocus, while traditional DSLR use phase detection. So-called 'hybrid' AF systems are becoming more common in Mirrorless DSLR cameras, combining advantages of both.
e) ability to assess exposure and show a magnified preview for accurate focusing of old, manual focus lenses
f) able to preview what picture will look like after effect of exposure / iso / speed etc setting. In traditional DSLR, you look in viewfinder, adjust settings for exposure / iso / speed / WB / shutter as per image in your mind & shoot the picture, & then look at shoot picture in lcd screen whether it is as per your mind, if it is not, you have to re-shoot. While in mirrorless DSLRs, whatever image is seen on lcd screen is picture with your all focus / exposure / shutter etc settings, you can tweak all settings in live, & when satisfied, shoot the picture.
Disadvantages of mirrorless DSLR:
a) can't match the autofocus speed of DSLRs when conducting continuous or predictive AF.
b) can't track moving subjects (specifically those moving towards or away from you).
c) struggle to focus in low light to a greater degree than we'd expect from an equivalent DSLRs.
d) need to always use the LCD or electronic viewfinder means the battery life of some Mirrorless cameras isn't quite in the 'shoot-all-day' range that many DSLRs offer
e) due to small camera bodies, batteries have often become small sized.
In short, my recommendation is DSLR - if size matters, go for mirrorless DSLR like Samsung's NX, Sony's NEX, Fujifilm's X and Canon's EF-M mounts.
