What is the difference between a DV camcorder and a digital camera?

The differences between DV cameras and digital cameras: different resolutions, different photoelectric systems, and different uses

1. Different resolutions

The number of pixels of digital cameras is as high as several Millions, the number of pixels in a single image of dynamic video is only hundreds of thousands, but dynamic video records dozens of frames per second, and the total amount of data is very huge.

The first thing to consider about the difficulty of DV cameras is the resolution. Due to the different visual perceptions of people, the requirements for the accuracy of dynamic images are much lower than those of static images. The video signals of standard PAL format and NTSC format .

If converted into pixels, the accuracy of a single picture is less than 300,000 pixels. A VGA-level (640x480, 300,000 pixels) video signal is already considered high-precision, even if it is a high-definition TV HDTV , a single picture is only 2 million pixels (1920x1080 pixels), so the current mainstream DV is still 800,000 pixels.

2. Different photoelectric systems

Digital cameras can pre-zoom and focus when taking a single photo. Accuracy is the first requirement. For accuracy, you can even give up a little speed. When taking dynamic images , zooming, focusing and image shooting are carried out at the same time, requiring the cooperation of the photoelectric system to not only be accurate, but also fast, and even the requirement for "fast" exceeds the accuracy.

It is difficult for DV cameras to take care of both aspects. Therefore, although many DVs can shoot video clips, they cannot perform zoom operations during shooting.

3. Different uses

Digital cameras are generally used to record static images, while DV cameras are used to record dynamic videos or pictures.
