A camera is a device that uses the principle of optical imaging to form an image and uses a film to record the image. It is an optical device used for photography. The lens turns the scene into an inverted image and focuses on the film. In order to make the image of the subject at different positions clear, in addition to the lens itself needs to correct aberrations, the object distance and image distance should also be kept in a conjugate relationship. For this reason, the lens should be able to move back and forth for focusing. In order to adapt to different bright and dark subjects, in order to obtain the correct amount of light on the film, it is necessary to control the length of the exposure time and the intensity of the light entering the lens. Therefore, the camera must set the shutter to control the length of the exposure time, and set the aperture to control the amount of light through the adjustment of the aperture size.
The main components include: imaging element, darkroom, imaging medium and imaging control structure. The imaging element can perform imaging. Usually a lens group made of optical glass, called a lens. Small holes, electromagnetic coils, etc. all act as "lenses" on specific equipment.
The imaging medium is responsible for capturing and recording images. Including film, CCD, CMOS, etc.
The dark room provides a 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 the image to achieve the final imaging effect of the image. Iris, shutter, focus control, etc.
Purpose: According to the performance characteristics of the product, the camera is usually used for some daily shooting.
Since the incident angle of light entering the wide-angle lens is relatively large, the performance of spherical aberration is more obvious in the wide-angle lens. Therefore, well-designed wide-angle lenses will use aspherical lenses to eliminate aberrations. For a telephoto digital camera, the lens covers different focal lengths from wide-angle to telephoto. Therefore, in order to ensure imaging in the wide-angle range, it is also necessary to add an aspheric lens to control the phase difference.
