Photosensitive chip in 4k USB camera module largely gathers the light folded by the lens and focuses the light. The photosensitive area is divided into different sizes. The larger the photosensitive zone, the lighter collected, and the unit pixel. The higher it is, the improved result will be achieved.
Integrated Circuit Board: An essential part of all automated devices. The structure is intricate and consists of an assortment of electronic material gears and main control processing chips (DSP). The electronic gear in the 4k USB camera module mainly plays the role of regulating power, reducing power usage, and filtering intrusion impurities. The main control processing chip plays a major role, like the CPU of a computer. It largely compresses and organizes the color data conveyed by the chip and enhances the effect. Therefore, the computing power of the main control chip plays a vital role in the image quality effect obtainable by the camera module.
The basic gears of the camera module are composed of the above three parts, other required mechanical gears are overlaid according to the purposes and effects that an imaging gear needs to achieve such as adding light panels to improve the night vision properties, IR-CUT to apply to complex environmental changes, etc. MIPI CSI camera modules have a wide range of uses. For example, common applications include video conferencing, face recognition, living inspection, authentication and identification, and scanning and filing.
After the lens captures the image, the photosensitive component circuit and control device in the MIPI CSI camera module develops the image and convert it into a digital signal, additionally, the digital signal is handled by DSP and changed into standard RGB, YUV, and other formats image signals for packing on the device, finally the image could be obtainable through displayer.
