What is the sharpness of millions of HD IR cameras and how does the sharpness of millions of HD IR cameras adjust?
1 is the definition of millions of high-definition infrared cameras, the edge of the screen is clear or fuzzy; the higher the sharpness, the clearer the edges, the more obvious the boundaries of the body and the background of the millions of high-definition infrared cameras, improve the clarity, but the subject is posted; reduce the sharpness The edges are blurry and the sense of clearness of the picture is reduced, but the level between the background and the background is strengthened, and it looks like a strong one.
The meaning of 2 million high-definition infrared camera sharpness means that: A pixel value = 10, adjacent B pixel value = 5, when A pixel becomes 12, B pixel becomes 3, which means that sharpness is increased by 3 to adjust Image sharpness, when the image clarity is slightly insufficient, you can make the image sharper with the sharpening method. Contrary to the softness and sharpness, the transitions of the images can be rounded and soft. As a Shenzhen surveillance camera manufacturer, Shenzhen Hua Antai Intelligent Technology Co., Ltd. has a very high quality requirement for millions of high-definition infrared cameras, especially millions of HD cameras, because millions of HD network cameras are generally used in key locations, and users' requirements and expectations are more High, if failure or debugging problems not only affect customer satisfaction, but also increase very large maintenance costs, so the entire production process of millions of high-definition infrared cameras, including material storage to process control or factory inspection requires strict control Implement each layer to ensure that the quality of the product is guaranteed.
What is the color reproduction degree of millions of high-definition infrared cameras and how is the color reproduction degree of millions of high-definition infrared cameras tested?
The color reproduction of 1 million HD IR cameras depends on the phase of the three primary color signals and luminance signals in the monitor.
2 Use the ColorBar on the test chart: If you see from the monitor and see the actual test chart, it is easy to see the color reproduction of the million HD IR cameras. In fact, this is the most difficult to measure, how do you determine Millions of high-definition infrared cameras wrong or the monitor with this color is not correct? If you think your monitor is not bad, then put the color, brightness, contrast knobs in the middle. If you can not determine the monitor is no problem, you can get a Test the disc and match the monitor color.
What is the automatic white balance of millions of high-definition infrared cameras and how does the automatic white balance of millions of high-definition infrared cameras be set?
1 Auto white balance is usually the default setting for millions of high-definition infrared cameras. A million-pixel high-definition infrared camera has a complex structure of a rectangular plot that determines the white balance reference point in the picture to achieve white balance adjustment. The accuracy of this automatic white balance is very high, but when shooting under poor lighting conditions, the effect is poor. For example, under cloudy weather, many automatic white balance systems have extremely poor results, which may cause bluing.
2ATW (Automatic White Balance) test automatically tracks the white balance. When testing the above color reproduction degree, the light source is switched, such as natural light, fluorescent lamp, light bulb and other light sources, a good HD IR camera can be switched at different color temperatures. Quickly get back the correct color, some of the machine, when suddenly moved out of the window under the light bulb, but also the whole reddish, or quickly move from the window to the light, the color continues to blue, is the white balance design is bad 3 so-called automatic white The balancing technique is to make the technical requirements of the TV curtain wall have good color consistency, but in practice it will inevitably drift. Regular calibration with a color analyzer is required, which is inconvenient and does not guarantee stable results.
