What is the difference between a digital camera and a digital video camera?

Abstract: With the advent of the era of high image quality, I think more and more people are not satisfied with the quality of the camera attached to the mobile phone and the function of the small digital camera at home, but rather hope to retain the beauty with images. But some people think that using a video camera is not as good as using a video camera. What is the difference between a digital camera and a digital camera?

What is the difference between a digital camera and a digital video camera?

1. The first difference between a digital camera and a digital video camera is the resolution

The number of pixels of a digital camera is as high as several million, and the number of pixels of a single image of a dynamic video is only several hundred thousand, but the dynamic video records dozens of frames every second, and the total data volume is very huge. The image processing chip of a digital camera is specially designed for processing static images. Dealing with dynamic streaming files is often a bit overwhelming, because the image processing chips of DC and DV are dedicated chips, and their high efficiency comes from their single function, so we should give consideration to both sides, either using a processor with more powerful computing power or sacrificing processing efficiency, while the former means expensive and the latter means low energy. On the other hand, the huge amount of data requires huge storage space, so the mainstream DV still uses magnetic tape, because even if the MPEG-4 format with high compression ratio is adopted, the 512MB memory card can only store high-precision video for more than ten minutes.

the first difficulty for p>DV to be used as DC is still the resolution. Due to people's different visual feelings, the requirement for the accuracy of dynamic images is much lower than that of static images. If the standard PAL and NTSC video signals are converted into pixels, the accuracy of a single picture is less than 3, pixels. The VGA-level video signal (64x48,3, pixels) is already high-precision, even if high-definition tv HDTV is single. As far as DC is concerned, the current 3 million pixel model has gradually withdrawn from the mainstream market, and household products have entered 5 million pixels.

2. The second difference between a digital camera and a digital video camera is that the photoelectric system

can zoom and focus in advance when shooting a single photo. Accuracy is the first requirement, and even a little speed can be given up for accuracy. When shooting dynamic images, zooming, focusing and image shooting are carried out at the same time, which requires the cooperation of photoelectric system to be not only accurate, but also fast, even exceeding the accuracy. Therefore, DC and DV have different requirements for the cooperation of photoelectric systems, so it is difficult to give consideration to both sides. Therefore, although many DCs can shoot video clips, they can't zoom in the middle of shooting, and many low-end models even lock the focus distance after the video starts.

digital cameras are not specially used for photography (still images). Its main functional advantages include dynamic image processing, high-power optical zoom, dynamic anti-shake processing and so on.

can the camera take pictures?

As far as the products in the current market are concerned, cameras are not as good as ordinary cameras. The best cameras are not as good as ordinary cameras. For the average family, at present, you can't have your cake and eat it. Like dynamic video, buy a video camera. I like high-quality photos and buy a camera.
