Analysis of key parameters of Mipi camera

The pixels of the MIPI camera determine the resolution of the image. The higher the number of pixels, the higher the resolution of the image. Common MIPI camera pixels include 5 million, 8 million, 12 million, 16 million, 21 million and other levels.

The specifications of the camera module will generally adopt MIPI interface and use COB or COF packaging technology. COB package has highly integrated and stable performance; The COF package is smaller and lighter, can be bent and folded, and is suitable for curved or curved devices.

The size of the camera chip has an impact on the size of the module and the shooting effect. Common chip sizes are 1/3.2 inch, 1/2.3 inch, 1/1.8 inch, and so on. The larger the chip size, the larger the pixels, so the image is better.

The camera is the main component of the MIPI interface, and its main function is to perform focusing and optical imaging. Common camera types are wide Angle lens, telephoto lens and zoom lens and other different lenses suitable for different scenes and needs.

VCM (VoiceCoilMotor) is a controllable diaphragm motor, which is an important component of MIPI camera to achieve autofocus. The performance of VCM directly affects the speed and accuracy of focusing. Under normal circumstances, the VCM of the MIPI camera is controlled through the I2C interface.

The output mode of MIPI camera generally includes MIPID-PHY, MIPIC-PHY and Sub-LVDS. The most commonly used is the MIPID-PHY, which has the advantages of high speed, low power consumption and high reliability.

Aperture is the size of the optical opening of the lens, which affects the light and shade of the image and the depth of field. The aperture value is smaller, the lens is brighter, and the depth of field is shallow; The aperture value is larger, the lens is darker, and the depth of field is deeper. MIPI cameras usually have a fixed aperture or automatic aperture.

The key parameters of the MIPI camera include pixel, module specification, chip size, lens, VCM, output mode and aperture. These parameters interact with each other to determine the image quality and application scenarios of the MIPI camera. In consumer electronics, such as smartphones, tablets, etc., MIPI cameras usually use COB package technology, the number of pixels is between 12 million and 21 million, the chip size is 1/2.3 inch, and the MIPID-PHY output mode is used, which has the characteristics of high speed and low power consumption. For industrial vision, medical equipment and other fields, MIPI cameras need higher pixels and better imaging effects, using COF packaging technology and larger chip size, and with different lenses and VCM to achieve high-speed, high-precision imaging.

MIPI camera has a wide range of applications, not only in mobile devices, smart home and other fields have been applied, but also in the car camera, security monitoring, aerospace and other fields have a wide range of applications. With the continuous development of new technologies such as 5G and the Internet of Things, MIPI cameras will be more widely used and become an indispensable part of the digital era.

In general, the MIPI camera is a digital camera, with many advantages, such as high resolution, low power consumption, high speed and high image quality. Pixels, module specifications, chip size, lens, VCM, output mode and aperture are the key parameters that determine the applicable scene and imaging effect of MIPI cameras.
