HD CMOS Camera Module for Doorbell
Camera Compact Module, referred to as CCM, is an electronic device that is crucial for image capture. In short, it is a device that converts the optical signal of an object into a digital signal that can be read and stored. It is mainly composed of a lens, image sensor, IR filter, circuit board and other components.
Lens: It is composed of a refraction layer and a filter. The refraction layer has a multi-layer structure. It is mixed with glass or plastic and glass-plastic to complete multiple light refractions and then project to the photosensitive chip. The filter is used to filter out some light that can be observed by the naked eye and can affect the color effect band.
A modern lens is generally a lens group consisting of several lenses. Lenses are divided into a glass (GLASS) and plastic (PLASTIC) according to the material. For example, the 5P lens represents a lens composed of 5 plastic lenses, and 1G+5P represents a glass-plastic hybrid lens composed of a glass lens and 5 plastic lenses.
Image sensor, including CMOS image sensor and CCD image sensor, is the core component of the camera module, and its quality directly affects the performance of CCM.
The function of the IR filter is to filter out the ultraviolet and infrared light that cannot be observed by the human eye, reflect the unnecessary light, remove impurities to prevent the color cast of the image, and its characteristics are also very important for the imaging effect of the final camera. effect.
The integrated circuit board is composed of a variety of electronic material components and the main control processing chip. Among them, the electronic components mainly play the role of controlling the voltage, reducing the power consumption, and filtering the interference impurities. The function of the main control processing chip is similar to that of the computer CPU. It mainly compresses and organizes the color data transmitted by the chip and optimizes the effect. Therefore, the computing power of the main control chip plays an important role in the effect presented by the camera module.
