Integrated lens creates high-definition monitoring core core technology

The standard of high-definition integrated lens quality is 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. Of course, it also includes the seriousness of ghosting, purple fringing, and dispersion. The key components mainly include the aperture, motor, and filter switching components.
After years of development of the integrated camera movement, the design of its core technology integrated lens and auto-focus algorithm has been quite mature.
After entering the era of high-definition, these technical problems have been resolved quickly. Currently, different products represented by Japanese lenses, Taiwan lenses, and domestic lenses have been formed. 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 terms of autofocus algorithms, several major solutions have also been formed at present, for example, HD image autofocus solutions represented by TI's DM368, FPGA and ASIC. The FPGA solution belongs to the hardware circuit implementation mode, and the stability is high. The effect and speed of autofocus are fast. The solution of the DM368 is a software system combined with the implementation of the hardware register. Its autofocusing effect is relatively good, but the speed and stability The sexual aspect needs to be tested; the ASIC solution is a hardware circuit with a simple software approach to achieve high stability, but the development flexibility of the movement manufacturers is very limited, it is difficult to improve the effect and speed of autofocus.
