What is the camera
The camera performs a task similar to the human eye. From here, scientists have tried to project functions and parts that pertain to the human body onto the devices in our hands. The camera receives the image to be captured through the light rays falling on the objects, as it is received through the lens towards the so-called image sensor, which is a chip inside the camera, where it converts these incident rays after being broken through the lens into electrical pulses that are read into processors The internal camera and its output via the video camera output, or through a still image in the case of cameras that capture still images.

lens function
The lens, which is the external part of the camera, has the function of gathering light as well as working to focus the image, as there are cameras that work by themselves to control the auto focus, and others work to focus the clarity of the image manually through screws that are located on the sides of the lens that you calibrate. According to vision, appropriate accuracy, and appropriate focus. There is also the ability to control the iris of the camera, Iris. This is in order to control the amount of light entering the camera

Since the greater the amount of light present in the scene to be photographed, the area of ​​the iris aperture decreases (and likening this to the human eye because if you want to enter a place with intense lighting, you try to close the eye aperture so as not to allow the entry of lighting with this huge amount, and vice versa). There are cameras that zoom in on the image and are called zoom cameras, and this depends on the camera lens and its focal length. The longer the focal length of the camera lens, the greater its ability to zoom in and see distant places. The zoom value of the image is known as X. There are cameras 10X, 18X, etc., and the value of this number indicates the ability of the camera lens to zoom in ten or eighteen times, etc.

How to measure camera clarity
To measure the clarity of the camera, there is something called Resolution in English, which is the ability of this camera to provide clarity by the number of pixels it contains. Better than that is by knowing the value of the pixels that the captured image or video from the camera provides us with; A 3 mega pixel camera is definitely better than a 2 mega pixel camera. Because the first camera contains 3 million pixels and the second has 2 million pixels, which gives greater clarity to the image by showing more details of the captured image or video.
