Is it normal to hear a little tick when clicking the "playback" button and after capturing an image?

I've just bought A550, and my question is, I hear a little tick sound from the camera after capturing an image and when clicking the "playback" button, Is it normal?, or there is something improper in my camera?, Help will be appreciated and Thanks in advance.

I've worked with a couple different powershots and have heard the "click" on both. The one I still have, I've had for almost 6 years and it still works great, "click" and all. Good luck and happy shooting.

Thanks Andrew so much for your reply, But I figured out something related to my problem that may be helpful.

I figured out where is this "tick" from? while I was looking at the center of my camera's lens when opening it or closing it, it seems like there's a little door that allows the view of the LCD (where i can see what the lens sees), the tick is heard when it's closed or opened or when the LCD view shifts between being OFF or ON.

(i.e. The camera is OFF (the LCD views nothing (is OFF as well)), when I open it (the LCD turns ON) I hear that "tick", or generally when the LCD switches between on and off anyway (going to stand by(power saving), capturing a photo, .....)

I'm sorry for repeating the question, but just to make sure there's nothing in my camera (as I bought it a couple of days ago)

The Question is, Is this normal to hear that "tick" or "click" , if anybody have the camera, do you hear that?

Thanks Andrew again, and hope to help me whether nothing on my camera or I should go to Canon.

Thanks much Andrew :-)
