What's the difference between a camera and a video camera?

The difference between a camera and a video camera is as follows:

1. Today's cameras can also take pictures. Cameras only pay attention to camera function and quality, and cameras pay attention to camera function and quality.

2. Photography is to save an image as a single document. Generally, the continuous shooting of photography is about ten per second at most, and an image is also saved as a file (picture file). Photography is the intermittent recording of scene images, which is what people call still images (photos).

3. Shooting is to save multiple images as one file, usually more than 25 images per second, and 50 or 60 images per second for high-definition cameras. All (each) images taken from beginning to end are saved as one file (video file). Shooting is the continuous recording of scene images, which is what people call moving images (videos).

First, the camera

A camera, referred to as a camera for short, is a device that uses the principle of optical imaging to form an image and records the image with a negative. Many devices that can record images have the characteristics of cameras. Medical imaging equipment, astronomical observation equipment, etc. A camera is an optical device used for photography.

Machinery. After the light reflected by the shot scene is focused by the camera lens and the shutter that controls the exposure, the shot scene forms a latent image on the photosensitive material in the camera box, and forms a permanent image after being developed and fixed. This technology is called photography. Divided into general photography and professional photography.

Second, the camera

There are many kinds of cameras and waterproof digital cameras, and the basic principle is the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device.

"Video signal". The photoelectric signal is very weak, so it needs to be amplified by pre-amplifier circuit and then processed and adjusted by various circuits. The final standard signal can be sent to video recorders and other recording media for recording, or spread through a propagation system, or sent to a monitor for display.
