Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Canon ELPH 100 HS is significantly lighter (66g ) than the Canon ELPH 510 HS which may become a big advantage especially on long walking trips.
Weather Sealing
Unfortunately neither the Canon ELPH 100 HS (IXUS 115 HS) nor Canon ELPH 510 HS (IXUS 1100 HS) provides any type of weather sealing in their bodies, so you have to give extra care especially when you are shooting outdoors.

LCD Screen Size and Features
Canon ELPH 510 HS's 3.20" LCD screen is slightly larger than Canon ELPH 100 HS's 3" screen.
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
