What is the basic structure of a camera?

The basic structure of a camera is generally divided into body, lens, viewfinder, back, film transport mechanism and other parts. If you are more detailed, it can be divided into lens, shutter mechanism, focusing and ranging system, viewfinder, film transport mechanism, body, back, etc.

The function of the corresponding structure: the imaging element performs imaging, and the small holes, electromagnetic coils, etc. all play the role of "lens" on specific equipment; the darkroom provides a connection and protection between the lens and the imaging medium The imaging medium is undisturbed; the imaging medium is responsible for capturing and recording the image. Including film, CMOS, etc.; the imaging control structure can change the way of imaging or recording images to achieve the final imaging effect of the image.

A camera is a device that uses optical imaging principles to form images and uses film to record the images. It is an optical instrument used for photography. In modern social life, there are many devices that can record images, and they all have the characteristics of cameras, such as medical imaging equipment, astronomical observation equipment, etc.

Camera maintenance:

1. Lens maintenance and cleaning

The lens is the most critical and fragile part of the camera, so you should be extremely careful when using the camera. Pay attention to the protection of the camera lens, do not let it get easily contaminated with dust, and do not let the lens be "touched" by dirty hands. Clean the lens only when absolutely necessary. When cleaning, it is best to blow off the dust with a blower, or gently brush it off with a soft brush.

2. Protection of the LCD screen

Color LCD screens are easily scratched by hard objects, especially color LCD screens without a protective film. It will leave permanent traces, so when using it, you can consider applying a protective film for your handheld computer or mobile phone, which has a very good effect on protecting the color LCD screen. At the same time, special attention should be paid to avoid high temperature damage to the color LCD display.

3. Battery use and maintenance

Reverse cameras generally use nickel metal hydride batteries or lithium batteries as power sources. Ni-MH batteries will produce a memory effect, which will reduce the total capacity and usage time of the battery. As time goes by, the stored charge will become less and less. Therefore, you should try to use up all the power before recharging. Pay attention to maintaining the integrity of the battery insulation. If any damage is found, it should be glued firmly with transparent tape.
