Which is better, flash camera or hard disk camera (what does flash camera mean)

High-speed photography refers to the technology of taking photos in a very fast time. In 1948, the American Society of Motion Picture and Television Engineers defines high-speed photography as a shooting speed of more than 128 frames per second and continuous shooting of at least 3 frames. High-speed photography can be regarded as the antonym of time-lapse photography. For high-speed photography, photography that only takes one frame to several minutes and hours per second and then shows at normal speed is called "time contraction photography" or micro-speed photography, which is usually used for long-term observation of extremely slow moving objects such as plant ecology and weather.

In daily application, high-speed photography may refer to the following two meanings: first, it refers to the static motion moment reflected by the photo itself, especially to reduce dynamic blur. One refers to a series of photos taken at high speed. These are also called motion cameras. The former requires a sensitive sensor or a very fast flash. The latter device can be a mechanical device or an electronic sensor, which is needed to capture continuous frames.

Video camera is a kind of equipment that records video by using optical principle. The invention of the camera was originally used in the production of movies and TV programs, but now it has become popular.

Just like cameras, previous high-speed cameras needed to use negatives or video tapes for recording. Since the invention of digital cameras, videos can be directly stored in flash memory. Nowadays, the high-speed video camera directly stores the video data in the hard disk of the fuselage, which can record dynamically or shoot statically, without bringing a digital camera at the same time. Household portable high-speed camera, with light body and convenient operation, is a kind of camera that many families will adopt now. Multi-head high-speed camera is more convenient. The improved high-speed camera, combined with high-speed photography technology, can shoot all kinds of exotic customs, and it is also the favorite travel companion of many camera lovers. At present, Shenyang Xingmai Technology Co., Ltd. is gradually expanding the performance and functions of its products and developing towards high-definition cameras.

A high-speed camera is a kind of camera used for high-speed photography. Compared with a general camera that shoots 24 frames per second, a high-speed camera can shoot at least 1000 frames per second, or at most 2 billion frames per second, depending on the model. After shooting, play it at normal speed. Early high-speed cameras were shot with negatives, similar to film cameras. After the popularization of CCD, CMOS and other technologies, it has progressed to digital shooting.

High-speed cameras are usually used in scientific research, such as impact test, trajectory, biological movement and so on. Athletes' movements, such as the pitching posture of baseball pitchers, are sometimes photographed by high-speed cameras for research and analysis. In addition, it is also used in the effects of TV and movies.
