a pixel is a picture element, not a "size". first consider how many elements are in the CCD imager array. next is how many arrays are used to produce a color picture, can be 1, 2, 3 or 4. most cameras are 1 or 3. and finally what is the pixel count on the recorded format.
The last can be figured, TV or Hard drive SD is 640x480, or 0.31 Megapixel. miniDV is 720x480 = 0.35 Megapixel. HD is 1080x1920 = 2.1 Megapixel.
The camera ideally will have CCD imagers that can produce this resolution. However look at the spec sheet because some cheesy manufacturers triple count the CCDs in the imager. Thus they claim a 6 megapixel imager, but in reality that is a 2 MP red, 2 MP blue and 2 MP green and produces a 2 MP color pixel, not a 6 MP color pixel image. Also the aspect ratio changes between SD and HD, so one mode or the other will not be using all the available pixels. Hopefully they spec the 16:9 size but that is not always the case.
So the ideal CCD imager is 16:9 and has 2 (or 6) mega elements.
