What is the unit of the camera?

Question 1: What department or station is the quantifier unit of the camera? Hope to adopt!

Question 2: What is the unit of the camera? To perfect it, Niu Niu said the maximum aperture of the lens.

Aperture is a ratio, yes, but to be precise,

F= focal length of the lens/diameter of light entering the lens part.

The smaller the aperture of the same lens is adjusted, the smaller the lens area used.

From the formula, we can also see why the long focal length of large aperture is often made like a cannon. The longer the focal length, the larger the lens aperture to ensure the same aperture.

This is why the light input of f 1.4 is twice that of f 1, because the aperture ratio is the ratio of the diameter to the focal length, not the ratio of the light input, but the square of the aperture ratio.

The square of 1 is 1, and the square of 1.4 is 1.96, which is close to 2. Therefore, the light input of f 1 is twice that of f 1.4.

Question 3: What is the unit of camera film? If the unit of 135 film of an ordinary camera is one film, Quan Huafu film camera is allowed to shoot 36 films with 135 film and 72 films with half-frame camera. A roll of 120 frame film is 12 (the imaging part is 6CM high and 72CM in total length, that is, 6X6 is 12, 6X7 is 10, and 645 is 16). If it's 135 film, an ordinary camera will do. There are many units of film, one frame is equal to 1/2 135, and the time is also 24 frames per second (a roll of 135 photographic film is only 3 seconds long on the film machine). The above is personal information. Please correct me if there are any mistakes.

Question 4: What does the distance unit in digital camera mean? The first m/cm is the conversion of meters /cm.

The second ft/in is feet/inches. FT is short for feet and foot in is short for inches. One inch is 2.54 cm, and one foot is 12 inch.

M = 100 cm = 3.28083 ft, 1 ft = 12 inch (inch) 1 cm =0.0328083 ft, 1 cm = 0.0328083 * 653.

Question 5: What does the unit pixel area of the camera mean? Is the number of pixels in an area of one square centimeter.

Question 6: What is the unit of pixels? Pixel refers to the smallest unit of complementary images. Generally we compare it to a point. In fact, it is formed by a single color. Unlike resolution, resolution refers to how many pixels there are per unit area. For example, we often say 1024*768: That is to say, for such a large area of the screen, there are 1024 pixels horizontally and 768 images vertically. The bigger the display, the more pixels it can hold. The size of 19 inch can reach 1280* 1024. For digital cameras, it means that this is a misunderstanding. What we want to see is the number of points per unit area, which is generally within 1 inch. Therefore, the higher the pixels of a digital camera, the better the photo quality.

Question 7: What is the unit of SLR shutter speed? Seconds, of course. For example, the shutter time is a fraction of a second.

Question 8: What accounting subjects does the camera bought by the company take? Digital cameras can be incorporated into fixed assets like computers.

Borrow: fixed assets

Taxes payable-VAT payable (input tax)

Loans: bank deposits

Question 9: What department or station is the quantifier unit of the camera? Hope to adopt!
