Structure and components

Generally speaking, the main components of a camera include: imaging element, darkroom, imaging medium and imaging control structure.

The imaging element can perform imaging. A lens group usually made of optical glass is called a lens. Small holes, electromagnetic coils, etc. They all play the role of "lens" in specific equipment.

The imaging medium is responsible for capturing and recording images. Including negatives, CCD, CMOS, etc.

The darkroom provides the connection between the lens and the imaging medium and protects the imaging medium from interference.

The control structure can change the way of imaging or recording images to achieve the final imaging effect. Aperture, shutter, focus control, etc.
