Camera Module is generally composed of the following parts: Lens, image sensor, base bar and line.
If it is a camera module with AF function (generally a mobile phone camera), most of them adopt VCM mode, which has one more coil than the above structure. By adding points to the coil, the lens can move vertically to achieve the function of focusing. In the case of a camera with a shake resistant feature, the lens is also able to move horizontally to achieve an optical shake resistant effect
Camera module selection
The sensor and lens in the camera module usually account for more than 90% of the cost, and the image quality is also determined by them.
First, choose the most appropriate sensor according to the price you can accept, the interface of the motherboard, and the resolution you need to take photos and video
The price of the sensor usually accounts for 40%-60% of the price of the module. In order to ensure that the resolution/frame rate can meet the requirements, sensors with better sensitivity and larger pixel area are selected at a certain cost.
Secondly, according to the purpose of the sensor you need, choose the lens with the appropriate size and field of view Angle. If a lens with a large field of view is needed, you can choose a fish-eye camera (also known as a wide-angle camera). However, for the image taken by the fisheye camera, there will be a distortion effect. In fact, the distortion effect can be corrected by itself.

I listened to the GM594 gaming headset package with a semi-open design, so that you can spy on the body of the headset before opening. Through transparent plastic, you can roughly see the appearance and color of the headset. This type of packaging is more suitable for store display.
Several important indicators of the headset are listed in the most conspicuous position of the box. The large 53mm sound unit, 115mm big ear pad, and sturdy and durable make Xiaobian look forward to the performance of this headset.
Because the headset is for gamers, it is more domineering in design. This is also the factor that many gamers prefer game headsets.
I listened to the GM594 full body with a steady black plastic material, the surface is matte and delicate texture. On the side of the earphones, the face is specially decorated with an oval silver-plated paint to add a bit of fashion to the headphones.
If the black and silver combination alone, it does not highlight my GM594 domineering sound style. So the brand is specially matched with the bright red earmuffs and head beam software, the red and black collision makes the headphones become very dazzling. I can tell the earphones that I am listening to the GM594 headphones.
The head beam is wrapped in protein skin, which not only can highlight the good texture of the earphone, but also protect the player's head. The thick sponge material can reduce the pressure on the top of the head beam, so that the wearer can wear the earphone for a long time. Without feeling tired.
The inside of the head beam is made of red egg white, and the outside is made of black leather. The inside is filled with sponge. The elastic sponge can increase the wearing comfort.
The 115mm ear pad is a bright spot for the earphone. The larger ear pad can reduce the pressure on the ear on both sides of the earphone, while leaving more space for the ear to enhance comfort. The ear pad is made of red protein skin and has good anti-sweat resistance. Staining ability, soft sponge is also very comfortable.
Headphones use metal brackets, which are rare in the 100 yuan headphones. Metal brackets can greatly enhance the toughness of the headphones, the headphones are not easy to break. At the same time, the elastic preservation period of the headphones is also greatly elongated.
The earphone is used for PC computers, so it adopts 3.5mm interface. The input and output are separated by two lines, which can ensure that the sound of listening is not interfered by the microphone line. The USB interface breathing light power supply interface.
The right side of the headset has a volume adjustment knob on the back, the player can adjust the volume of the headset in the game. Do not open the system's volume control panel. In the player's intense game competition, it is not possible to adjust the volume of the desktop. The volume button is directly installed on the earphone to greatly facilitate the player's control.
The headphones use a high-sensitivity microphone. The microphone position design is in place, and the shape also echoes the entire style of the headset.
I listen to the GM594 with a dragon-shaped breathing light, which can display a variety of colors. A variety of colors are switched in turn. In addition to providing the player with a sense of hearing, the earphone can also help the player to show the personality side.
The ear pressure of the earphone is moderate, just enough to be fixed on the head. The large size of the ear pad wraps very well, the earphones will not be stuffy inside, and the pressure on the ears on both sides is very uniform. The overall wearing comfort is remarkable.
Although the microphone can not adjust the angle freely, the position design of the Wanjin oil is also good. The directional microphone has a moderate range of recording, which can be recorded into the human voice, and the sound of the surrounding scene is greatly diluted. The recording effect is clear and realistic.
Call of Duty OL test, the sound field of the headphones is wide, you can hear the wide background music of the battlefield. The positioning of the enemy's position is very good, you can clearly distinguish the direction of the enemy's gunshots and the depth of the footsteps. The headphones are obviously optimized in low frequency, low frequency Powerful and strong, the sound of gunshots and explosions will not diverge, nor will it give a sensation.
The earphones are biased towards the middle and lower discs. The low frequency is strong and powerful, and it is not loud. Xiaobian prefers this style. However, the emphasis on low frequency makes the overall sound quality become true. It is loved by many players who like to listen to music. The aspect is more prominent, the vocal outline is clear, and the background music is separated, and the overall listening effect is also good.
I listened to the wide sound field and precise positioning characteristics of the GM594 gaming headset to impress Xiaobian. With solid workmanship and beautiful color matching, the addition of breathing lights can cater to the tastes of gamers.
