Does anybody know or understand why a 800k CCD camcorder only has effective pixels of 400k? The same goes for mega pixel camcorders too .. a 1.33MP camcorder only has 1MP effective. (Figures from manufacturers websites; Canon, Sony etc..) What is mean't by "effective pixels"? When buying a camcorder (I currently have a Digital 8 camcorder) is a 800k CCD (effective pixels 400k) better than what I have now or should I look at a mega pixel version? Thanks in advance. Clive.
