Why does my camera keep freezing after I take a picture?

Every time I take a picture, the image stays on the screen for upwards of 10 seconds, and I often have to turn the camera off and back on before I can use it again. This, of course, makes taking quick back-to-back pictures extremely difficult, and I usually miss great photo opportunities.

I've tried holding the power button for 10 seconds to reset the device in hopes of resolving the issue. I have searched for other online resources but haven't been able to find any answers. I'm not tech savvy enough to know if it's a software problem or if I need a new screen or a whole new camera.

What do you suggest I do so that my camera stops freezing in between shots?
