The difference between digital dv camera and digital camera

Lead: Digital dv camera, don't think it's mysterious, it's just a digital camera we often say. Now people's living standards have been greatly improved, and they have the economic ability and spiritual needs to buy private photographic equipment. However, there are still many netizens who don't know much about photographic equipment, and it is inevitable that they will be hindered when purchasing. Moreover, photographic equipment is just a general term, which is divided into camera, camera, SLR, single battery and other types, and there are many differences between them. The following small series will introduce the difference between digital dv camera and digital camera.

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

The number of pixels in digital cameras is as high as several million, while the number of pixels in a single image of dynamic video is only several hundred thousand. However, dynamic video records dozens of frames per second, and the total amount of data is huge. Digital camera's image processing chip is specially designed for processing still pictures, and it is often a bit inadequate to process dynamic streaming files. Because both DC and DV's image processing chips are dedicated chips, their high efficiency comes from single function, so we should give consideration to two aspects, either using a processor with more powerful computing power or on the one hand, the huge amount of data requires huge storage space, so the mainstream DV still uses tape, because even though MPEG-4 format with high compression ratio and 5 12MB memory card are adopted.

The first difficulty in using DV as DC is resolution. Because people's visual experience is different, the accuracy of dynamic images is much lower than that of static images. If standard PAL and NTSC video signals are converted into pixels, the accuracy of a single picture is less than 300,000 pixels. The VGA-level video signal (640x480,300,000 pixels) is already of high precision. Even for HDTV, a single picture is only 2 million pixels (1920x 1080 pixels), so the current mainstream DV is still 800,000 pixels. As far as DC is concerned, the current 3-megapixel model has gradually withdrawn from the mainstream market, and household products have entered 5 million pixels.

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

When taking a single photo, you can zoom in advance. Accuracy is the first requirement, and you can even give up a little speed 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 and even more accurate. 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 after the video starts.

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

As far as the products in the current market are concerned, the camera's photographing effect is not as good as that of 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 bought a camera.

Summary: The above is the difference between digital dv camera and digital camera compiled by Bian Xiao. Do you already know what is going on? Generally speaking, those who like photography can buy a digital dv camera, and those who like taking pictures can choose a digital camera. They have different specialties in different fields, it's as simple as that, but generally speaking, digital cameras are better than digital cameras. Although the ability to take pictures is slightly poor, it is enough. You just need to know what you like before you buy it. I hope Bian Xiao's article can help you.
