Movement of the core member <br> <br> one machine movement mainly composed of two parts: an optical portion and the hardware (board autofocus). The optical part is the imaging system of the all-in-one movement, usually called the all-in-one lens. The camera lens is the core component of the all-in-one movement, and it directly affects the quality of the all-in-one movement. The R&D and manufacturers of integrated camera movements basically use outsourced camera lenses.
The criteria for judging camera lens quality can be roughly divided into: optical performance, stability and consistency of key components. The optical performance mainly refers to the resolution of the lens under various optical multiples; other issues include ghosting, purple fringing, and dispersion. Key components include: aperture, motor and filter switching and other components. According to the quality of all-in-one lens, it can be roughly divided into three levels: Japanese lens, Taiwan lens and domestic lens. Japanese lenses generally perform well in terms of optical performance and stability, but their prices are relatively high. Taiwan's lenses are relatively cost-effective, but their optical performance, especially high-resolution image performance, is insufficient; while domestic manufacturers' one-camera lenses do not perform well in terms of stability and consistency. ideal.
In addition, the filter is also part of this optical system, but it is not always valued by camera development companies. High-quality filters have a unique effect on the color of the image and reduce the optical deficiencies of the lens. Related to the optical system is the photosensitive device. Since the monitoring environment of the integrated machine core application usually requires all-day monitoring, it has the same requirements for day and night. To take into account both the daytime and nighttime effects, CCDs are generally used today, and since the aperture of optical lenses on standard-definition lenses is only 1/4 inch, the SD caliber movements generally select 1/4-inch SONY CCDs (especially low-noise Excellent performance). For high-definition one machine movement you need to select the photosensitive device according to the lens aperture. CMOS imaging devices have consistently outperformed CCDs in terms of speed and low noise, while the latest CMOS has improved greatly in terms of low noise. In terms of comprehensive cost-effectiveness, CMOS is also superior to CCD in terms of back-end DSP processing and heat generation; therefore, CMOS sensors will be used more and more in high-definition integrated machine cores (especially digital high-definition integrated machine cores). In addition to the optical system, the hardware and software systems are the main development parts of the All-In-One Movement Development Company. Its core technology is auto focus.
<br> <br> autofocus advantages compared with ordinary cameras, one machine movement main difference is that the autofocus (AutoFocus), which is the bottleneck restricting the development of domestic movement of one machine. Focus on the speed and effectiveness of the direct impact on the user to monitor the scene image capture and video. A good product can be accurately focused at one time. Conversely, when focusing, it will move back and forth. It takes 3 or 4 shots to focus, and even more, the focus is less than the “clearest pointâ€.
The technology of automatic focusing has become a technical problem that manufacturers urgently need to solve. At present, there are two active and passive autofocus implementations, of which the active autofocus is relatively simple and the cost is low, but the control is not as flexible as the passive autofocus, the focus accuracy and the effect are poor, while the passive autofocus generally captures the video signal. Calculating the energy edge operator or extracting high-frequency components is flexible in control and dominant in the algorithm, and the focus accuracy is better, including the focusing of high-contrast scenes and low-illumination scenes.
The performance of autofocus can be evaluated from three aspects: focusing accuracy, focusing speed, and stability at the time of focusing. Focus accuracy is mainly reflected in various environments, various optical multiple focus accuracy. The various environments mainly focus on various illuminations, especially the focusing accuracy of the evening. In scenes with lighting scenes and illumination below 1 Lux, different focusing algorithms have different focusing accuracy, which is a major difficulty in focusing algorithms. 
Detailed: What is an integrated camera
Generally speaking, the all-in-one camera should specifically refer to the camera built-in, auto-focusing integrated camera integrated camera now specifically refers to the camera can be automatically focused, built-in camera, its technology from the development of home camera technology, and traditional cameras Compared with the compact and beautiful camera, the integrated camera is easy to install and use. It has a wide monitoring range and high cost performance. After successfully applied in the video display platform of the education industry, the integrated camera is forming a new round of impact on the security industry monitoring system.
