Question:

In the camera lens, 1 / 2.3 inch means what it means

In the camera lens, 1 / 2.3 inch means what it means

Answer:

Configuration 1 / 2.3 inch digital camera is usually low-end or although not low-end but most of the telephoto camera (optical zoom more than 10 times), the use of 1 / 2.3 inch advantage is the camera's volume can be done Small, like a card machine and the like are used in such photosensitive components, and the use of a little more photosensitive components of the camera size to do some big, of course, the quality of the image will be better.
That is, 1 / 2.3 inch area is the smallest. Determine the digital camera image quality has several large pieces, including the lens, the image processor and there is the photosensitive element, which is the greater the better components, of course, the bigger the more expensive, it is better than you buy a house area to pay the greater the money The more you want. How big is this 1 / 2.3 inch? We do not say that the formula, and directly to the answer: about 23 square millimeters, very small, may be similar to the size of the keypad on the phone, even in the home digital camera is usually equipped with the largest 2/3 inch sensor only 54 Square mm, but also more than double the size of 1 / 2.3 inch. Is a little bit of the camera to sell a little bit is not cheap, and some more expensive than the entry-level digital SLR.
Read the previous answer, completely unintelligible, especially the so-called recommended answer, what lens aperture F 2.3, wrong. In order not to be misled, I say a few words: not you refer to the lens, refers to the important parameters of the digital camera, the current home digital camera used in the sensor (CCD or CMOS, the role of the previous film is equivalent to the area) (From large to small) 2/3 1 / 1.6 1 / 1.7 1 / 1.8 1/2 1 / 2.3 inch.
1: in the camera lens, 1 / 2.3 removed in., The meaning should be the lens aperture 1 / 2.3 that F2.3. 2: 1 / 2.3 inch, as Lou Sheng said nothing to do with the lens, refers to the size of the camera photosensitive components. Ie diagonal length is 1 / 2.3 inch (11 mm). The aspect ratio is generally 5: 4.
