Well, now I'd explain the difference between a point-and-shoot and a DSLR (Digital Single Lens Reflex).
Have you heard the term viewfinder? Well for those who don't know, an image will suffice.
You have understood now what the viewfinder of a camera is. It's where you put your eye, and you're able to see the image, and capture it.
The image that we see on the viewfinder of a point-and-shoot (I'll call it a P-S from now on), isn't the same as captured by the camera's image sensor. In easy words, we are not able to see the same image which the camera's image sensor sees. It's because the image is finally projected on the viewfinder after passing it through two separate lenses, one before the sensor, and one before the viewfinder. It's regardless to mention that after passing through two lenses, the image is far more deviated from the original. That's why people say that images of P-S cameras lack vividness.
SLR's, on the other hand, have only one lens before the image is projected on the viewfinder. As the image passes through the primary lens (the lens in the front of the camera), a mirror diverts it to the camera's viewfinder. So, the image we see in the viewfinder of an SLR, is exactly same as the camera lens sees. That's why, DSLR images look far more realistic and vivid than those of P-S's. After that the mirror retracts, so as to the image can be recorded on the sensor. For that, in many DSLRs, the image can't be previewed on the LCD.
Hope you have now got why they are called Single Lens Reflex.
A DSLR's capability is much more than a P-S. A 16 MP DSLR will shoot much more vivid and vibrant images than a 16 MP P-S. Check out my later posts for further discussion on this matter.
