Younger guy secretly taking pictures of me... Is that normal? Should I confront him?

Anonymous
I work with college students. I'm a little older than this student. We work together at least once a week. It has come to my attention that he's been photographing and video tapping me when we're in the same room/talking. It is just of my face and nothing inappropriate like my chest or butt, etc...however, it's a little strange.

He makes off-hand comments about us "hanging out" on weekends (tries to joke about me "coming with" the group of students I work with/around).

He's very nice and I had suspicious that he had a little crush, but the photo thing is bothering me a little. I just don't know how or if I should confront him.

Is this normal? Is he just shy and awkward? His friends are always teasing him about getting a date, so I think he's feeling very single as well.
