What is the principle of camera imaging?

Traditional camera imaging

1. The lens focuses the scene image on the film.

2. The photosensitizer on the chip will change with the light.

3. The changed photosensitive agent on the wafer is developed and fixed by the developer.

4. Form an image that is opposite or complementary to the scenery.

5. Is the formed image a real image?

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.
