What are the basic device functions and main functions of the camera?

For example, the shutter is to control the speed of the camera, and the aperture is to control the amount of light entering the light, and the larger the aperture, the better the bokeh effect. There are a lot of other contents, and you can search for professional terms in the encyclopedia.

1.Classified according to photosensitive media: film machine, digital machine.

2.Classified by framing method: single-lens reflex viewfinder camera, rangefinder camera, frosted glass viewfinder camera, electronic viewfinder camera.

3.Classified according to the size of the photosensitive medium: large-format camera, 120 camera, 135 camera, card machine.

In terms of function: the film machine needs to be processed and scanned before the film can be produced; The digital machine can directly produce films.

The frame of the DSLR camera is unbiased, what you see is what you get, and you can use lenses of all focal lengths; The framing range of ground glass and electronic viewfinder cameras is similar to that of a single shot, but the effect is slightly different, and you can also use lenses of various focal lengths; The rangefinder camera has a slight error between the framing and the final image, and the telephoto lens cannot be used.

Large-format cameras and 120 cameras have better image quality and rich details due to the large area of photosensitive media. The 135 camera is slightly worse, and the card camera has the worst image quality.

That's probably how the <> works, and the specific component shape and operation method will start separately. The left is the lens, the right is the fuselage, the top of the fuselage is a large bag of pentaprism, and the reflection system of the middle optical path is the SLR.

The origin of the name.

The appearance is sauce purple.

This is going to read a book, and it is not clear in a few words here.

The camera is very widely used in life, and people will often use it, but what are the components of the camera? Let's take a look at the composition of a camera. Lens The lens makes the scene inverted and focused on the film.

In order to make the image of the photographed object in different positions clear, in addition to the correct aberration of the lens itself, the object distance and image distance should also maintain the conjugate relationship. To do this, the lens should be able to move back and forth to focus, so the camera should generally have a focusing mechanism. Viewfinder In order to determine the extent of the subject to be photographed and to facilitate the composition of the shot, the camera should be equipped with a viewfinder.

The viewfinder of modern cameras also has a range measurement and focusing function. Shutter and aperture control mechanism, in order to adapt to different light and dark subjects, in order to obtain the correct amount of light on the film, it is necessary to control the length of time and the intensity of the light entering the lens. Therefore, the camera must set the shutter to control the length of time, and set the aperture to control the amount of light by adjusting the size of the aperture.

In order to prepare for the second shooting, the film after ** needs to be pulled away, and the film without ** needs to be pulled over, so modern cameras need to have a film loss mechanism. In order to indicate the number of shots taken on film, a counting mechanism is required. The body is both the camera obsca and the combination of the camera's components.

You can use a block diagram to represent the most basic components of a camera. The components of a camera are roughly the ones introduced above, and I hope these will help you better understand the camera.

The lens, which projects the image onto a photosensitive device, consists of several sets of concave and convex lenses, as well as a focusing mechanism. （1）

Photosensitive devices, commonly known as CCDs or CMOS, have dense pixels on them, and each pixel is a separate photoreceptor unit that can record the brightness and color of the light projected onto it

The processor processes the information from the sensor into a digital ** for recording on the storage device.

Storage devices, generally have SD cards or CF cards, Sony has memory sticks.

The reflector reflects the light from the lens into the pentaprism (2) pentaprism (7), and reflects the light from the lens and the reflector into the viewfinder window (8) The restoration photosensitive plate is about to be sensed, that is, the ** that is about to be shot, which is convenient for shooting framing.
