What are the components of a traditional camera and a digital camera?

Traditional cameras: optical lens, viewfinder, aperture, shutter, film window, film rolling mechanism and function control, etc.

Digital camera: In addition to the above parts, there are also CCD storage media, etc.

The basic structure of a digital camera is almost as follows: lens, image sensor, imaging element, focus module, light metering module, viewfinder (display), and various control buttons or levers.

Specifically, the basic structure of a digital camera is ...... composed of the following parts

First of all, the lens is responsible for receiving the light and imaging it. ......In this process, the focusing module and the metering module work to complete the focusing and metering, so as to obtain a clear, sharp and accurate image.

The image created by the lens then falls on the image sensor, which receives the optical signal and converts it into an electrical signal.

The image processor then processes the electrical signal from the image sensor to obtain a digital **.

This digital ** is then stored as a file in the memory card of the digital camera and displayed on the display.

As for the viewfinder, it is the ...... that the user uses to frame the frame while shootingBy looking at the viewfinder, the user can know what the image of the lens looks like, and then the ...... can be composedFor some digital cameras, there is no viewfinder, but a ...... that uses a display screen to frame the viewAlthough the operation is different, the display principle is almost ......

The components of a digital camera include: a lens module includes a lens, a dichroic mirror, a motor that controls the lens zoom, and a motor driver chip; The CCD CMOS image sensor converts light into a digital signal.

CCD image sensor, which is equivalent to the photosensitive film of a conventional camera. Another important component is the DSP for image processing, such as the image processing chip DigiC used in Canon digital cameras, which is used for image compression, conversion, filtering, correction and other work, and is the "brain" of the camera.

There is also an EPROM chip that holds the firmware (firmware) of the camera, which is equivalent to the BIOS chip of the computer motherboard, or the operating system of the entire camera, which can usually be upgraded.

A digital camera is composed of optical photographic lenses, DSP digital signal processors, CCD image sensors, optical viewfinders, LCD screens, flashes, memory cards, batteries and other main functional components.

The digital camera is mainly composed of two parts: the framing system and the imaging system. Among them, the framing system consists of three parts: reflector, pentaprism, and viewfinder, while the imaging system is composed of a shutter unit and an image sensor.
