Effective Pixels?

  Sapins 10:35 29 Jun 03

I have just read an advert for system with a digital camera included which has 2.2million "Effective" pixels. What are they and why do I get the feeling this is a bit of a con?

I share your scepticism.......Sounds like sales-speak for "nearly as good as"!

Another line which used to be used a lot when advertising scanners said something like 300 d.p.i (600 interpolated). To me it would have been more honest to say "guessed".

Usually the "effective" pixels are slightly less than the actual pixels. I presume it's something to do with a few being unused, or used for other purposes.

"To me it would have been more honest to say "guessed"."

Calculated is more correct - and there are different algorithms for doing the calculation.

click here Will explain the difference, most cameras as described this way now. j.

Just had a look at my own link, think if I have understood it correctly. "Effective" pixels" is a more accurate/truthful way of describing the amount of pixels the camera will use. j.

OK It is good for the soul to recognise that this is being honest and not deceptive at all.

Thanks for your input folks, I have a Friend who is considering buying a digital camera so he can relax if this is mentioned in the spec.
Thanks again,

Regards, Sapins.
