Digital Video Camera Explaination?

Greetings:

I'm having a trouble understanding the megapixel
issue of Digital Camcorders.
When a manufacture states that their digital camcorder has a 2, 3, or 5 megapixel chip, is this chip for their Digital still picture or for their video.
Also, what would be considered above average video quality, 640 X 480, or higher.

I'm searching for small digital video camera, with a Secure Digital card slot, which can give very good video quality.

Regards Robert

For video it's not megapixel unless we talk of HD.

Your common NTSC or PAL video is sub megapixel. The reason for megapixel sensors are simple in that you get some digital camera function and in better cameras you can zoom in a digital method without degradation.

Until we talk of HDTV quality camcorders, the video still is sub-megapixel. Many get sorely confused as they never think that the video signal is limited by the standards.

Hello Bob:

If the video quality on these cameras are less than a megapixel, then how do companies like Sony, Panasonic, JVC, etc, do it.
Their video quality is very good, Panasonic has a Mpeg 2 feature on one of their cameras.
Does this mean we all have to wait until digital camcorder companies develop chips with above one megapixel video quality?

You need to do some research on NTSC or PAL.

In reply to: Then explain this

I wish you had written which since they vary a little in the numbers. Once you do your research, how would you shove above 1 megapixels into NTSC and PAL?

Hope this helps you understand the underlying issue.

Apples and Oranges!! Apples/video resulition in pixels. Oranges/still picture resuliton in pixels.
A video camera that has the still picture feature has 2 ratings. One for stills and one for video. The video one will be around 290k~300k pixels. John
