Camera Module

Camera Module, full name CameraCompact Module, short for CCM. CCM consists of four parts: lens, sensor, FPC and DSP. A lens, a DSP, and a sensor are the important components that determine the quality of a camera. The key technologies of CCM are optical design technology, aspherical mirror making technology and optical coating technology.

Working principle: The light gathered by lens is converted into electrical signal by CMOS or CCD integrated circuit, and then converted into digital image signal by internal image processor (ISP), which is then processed by digital signal processor (DSP) and converted into standard GRB, YUV and other format image signals.

hardware

Lens n.

Lens is a device that can receive light signals and concentrate them on CMOS/CCD sensor. Lens determines the lighting rate of the sensor. The overall effect is relative to a convex Lens. General structure of the Camera Lens is composed of a few pieces of lens, points with PLASTIC lens (PLASTIC) and the GLASS lens (GLASS), usually with camera lens the structure are: 1 p, 2 p, 1 g1p, g3p 1, 2 g2p, 4 g, 8 p, etc. The more lenses, the higher the cost; Glass lenses are more expensive than plastic lenses, but glass lenses do a better job of imaging than plastic lenses.

indicators

1. The pixel

The sensor has a number of light-sensitive units that convert light into electrical charges to form an electronic image of the object. And in the sensor, each light-sensitive unit corresponds to a pixel, the more Pixels, meaning that it is able to sense more details of an object, so that the image is clearer, the higher the pixel, which means the image effect is clearer.

2. The Frame Rate

Refers to the number of images recorded or played per unit time. A series of pictures will produce animation effect if they are played continuously. According to the human visual system, when the playing speed of pictures is greater than 15 frames per second (i.e., 15 frames), the human eye can hardly see the jump of pictures. The flicker will not be detected when it reaches 24 to 30 frames /s (i.e., 24 to 30 frames). Frames per second (FPS), or frame rate, represents the number of times the graphics sensor can be updated per second while in the processing field. A higher frame rate results in a smoother, more realistic visual experience.
