There may be some doubt that the novice to use fixed Jiaozuo hanging camera is not climbing first go, not conducive to basic lea

transmission speed of USB interfaces is much higher than that of serial ports and parallel ports, therefore, the current market hotspot is the USB interface digital camera. The following mainly refers to the digital camera with USB interface. How cameras work The working principle of the camera is roughly as follows: the scene is projected to the image sensor surface through an optical image generated by the lens (

Today, photography has become one of the most important functions of mobile phones, and is also the first factor in the cost of acquiring mobile phones.

The concept of aperture Aperture should be when we contact exposure, to understand the first concept, the number of aperture is very strange, and there is no law, F2.8, F4, F5.6 ...

Aperture:The English name of the aperture is aperture. the aperture is also called the speed of the lens and the sensitivity of the camera. It is generally expressed in uppercase.It refers to the relative aperture of the lens, not the absolute diameter, so it is easy to misunderstand that the larger the F value, the larger the aperture. In fact, the smaller the value, the larger the aperture.Aperture f = fo

. Increasing the shutter speed will increase the probability of photo clarity. Of course, when a hand-held camera increases the shutter speed, it is bound to open a large aperture and thus lose the "large depth of field". However, to ensure the clarity of the photo, giving up the depth of field is a last resort. Another common mistake is that when the shutter is pressed, the hand is suddenly raised, which produces a very high vibration. It is better to press the shutter and wait until the shooti

Ambient Light)All light in an environment, including sunlight and artificial light sources such as tungsten lamps or fluorescent lamps. It is also called available light.

Video lens segmentation (lens boundary detection)Lens segmentation is the first step of video processing and the basis of subsequent video processing

When purchasing a digital camera, I believe many people will feel overwhelmed by the complicated parameters of the digital camera. Due to the rapid development of digital imaging technology, even those who often pay attention to this industry are often confused about some new technologies.

Basic Knowledge pixel, photosensitive element, size, valid pixel, resolutio

1. focus with a long focal length. When using a zoom lens, the correct focus method is to first focus with a long focal length, and then select a proper focal length for shooting. Because the maximum and minimum depth of field of the image to be taken during the long focal length, this facilitates accurate focus. In the case of complex back-to-light or light, it also helps to select the appropriate local light measurement, without approaching the subj
