What Webcams Do?

The entire process Webcams accomplish can be simplified into these three aspects:

  • Hardware: A Webcam connected to your computer through the USB port.
  • Software: The software which accepts images from the webcam time to time
  • Broadcasting: A server to store your images and broadcast them on the internet.

The hardware involved is similar to that present in digital cameras. The working mechanism involves a small lens which captures light in form of pixels and assigns strings of 1’s and 0’s uniquely to each pixel. Now the most important factor is the frame rate, which determines if this image is just a still image or a streaming video. It is recommended that your webcam has a frame rate of 30 frames per second (A frame is simply one static image).

But the main difference from a digital camera is, a web cam doesn’t have any memory card or such options. All it does is transmits this image information (in form of string of numbers) to the computer. The software then plays its part based on the resources it collects from the user. Generally, the quality of images produced from the webcam is much lower than the basic megapixel digital camera in the market. This is mainly to enable faster transmission of these images even across slow internet connections.

But can your digital cameras be used as webcams?

Actually it’s a ‘YES’ but with many complications. First of all there is no reason in the world you would want to use a digital camera after taking a look at these points:

  • Digital cameras are not made keeping computers in mind, so USB connectivity is a big question mark!
  • Though you have a proper USB connectivity, thing is that the batteries in the digital camera need not more than a 5 minutes charging, after which there is constant heating of your digital
  • With more resolution comes more problems, so if incase you somehow choose not to care of the above issues you will take a beating here. Simply the larger the image size the difficult it gets while streaming and eventually video chat will be a mess.
