In this article I will tell you that ,What are the uses of camera in smartphone?, And what are the functions of all, because there must be information about a smartphone camera so that it can be known that there are many terms in the camera behind capturing a great image.

Common camera terms used in smartphones Common Camera Terms used in Smartphone

smart fone There are many common words in the camera which are used by everyone, but there is no detailed information about all of them, what are their functions, so let us understand in detail how many types of words are used in the camera and how everyone plays their role in capturing an image.

aperture
HDR
Image Stabilization (IS)
Optical Zoom vs Digital Zoom
AI mode
Slow Motion And Time Lapse
ultra wide
ToF lens
MACRO LENS
ISO

1. What is aperture

The hole in the middle of the mobile camera lens is called Aperture, it is always measured in f value. Mobile I must have seen that Aperture is f/1.4, f/2.0, f/2.8, f/4.0, f/5.6, f/8.0, so let’s understand it with an example, the smaller the f number of the aperture, the bigger the hole in the middle of the lens will be, that is, it will be able to capture more and more light, so that the brightness in the image will be seen as well, meaning the picture will appear very clear.

On the contrary, if the f number of the aperture is larger, the hole in the middle of the lens will be smaller so that it will not be able to capture that much light and darkness will be seen in the image.

Therefore, compared to the smartphone camera, the aperture hole in the DSLR camera is very large, this is the reason that the picture taken from the DSLR camera is clearly visible.

2. What is HDR? What Is HDR

Full form of HDR high dynamic range (High Dynamic Range) It is present at the top of the smartphone camera, which is used to click images in more sunlight and shade. For example, when you click a picture in sunlight, then your face appears black due to sunlight behind you and shade in front.

In such a situation, when you click a picture by turning on HDR mode, then it captures the image in three ways, high exposure, low exposure and normal exposure, and by combining all three, it creates a final image that you see, which balances more light and low light, so that the quality of your image can be seen better in both lights.

3. What is Image Stabilization (IS) What Is Image Stabilization

Image Stabilization is called Image Stabilization in Hindi, as the name itself suggests, Image Stabilization means pulling any image very stable, its work is that when you click an image, it adjusts the movement of your body and prepares a picture without any blur, there are two types of OIS (OIS) and EIS (EIS).

(1.) OIS – The full name of OIS is Optical Image Stabilization, it is a hardware It is a technology that is used in the camera, its job is to create stability in the image. For example, when you take a photo in a crowded place, then due to the movement of the hands, the mobile shakes and blur is seen in the photo. This is where optical image stabilization technology is used. It has a small gyroscope which tells the camera how much the mobile is shaken.

Due to which it detects the movement and rotates the camera in the opposite direction, that is, if your hand moves in the right direction, then the camera rotates it in the left direction, so that the stability of the image remains and the photo is clearly visible.

(2.) EIS – EIS The full form of Electronic Image Stabilization is this one Software There is a technique which is used to enter this mode in any smartphone through an app. This technique is mostly used in taking videos.

For example, when you make a video while walking, then the video appears very shaken, in such a situation, if you make a video by turning on this mode, then it Video Crops some part of the video (where there is a slight blurring) so that the video looks very smooth and stable, this technique also works by gyroscope.

4. What is optical zoom and digital zoom

Both optical zoom and digital zoom are the process of taking the image by zooming, so let us know what is the difference between the two. In optical zoom, an actual lens is used and gives the option of zooming before capturing the image and the quality of the image is seen much better.

Whereas the camera in digital zoom usually helps in cropping the image and the same image Software Magnifies with the help of which you must have seen many times that the quality of the image becomes completely useless, so an optical zoom is better than a digital zoom.

5. What is Artificial Intelligence (AI) What Is AI

AI mode means that it algorithm It shows what kind of scene your camera software is capturing, like if you take a photo of food, it will set it accordingly, if you take a photo of nature, it will set it accordingly, and when you take a photo in Portrait, the blur in the background is all done by AI mode, which means AI mode setting is working behind any photo you are taking.

What Is Slow Motion And Time Lapse

You must have seen slow motion and time lapse in a smartphone camera because usually when you take a Video If we take it then 30 Fps (frame per second) comes out in one second means 30 frames come out and you see a picture like one second, two seconds etc.

Slow motion When you extract a video in slow motion, then it takes 240 frames in a second, then when you convert it to 30 frames, then the one second you used to see will now appear in 8 seconds or 10 seconds, that is why it becomes slow motion.

Time Lapse Time Lapse means to fast a video, it does the exact opposite of slow motion, that is, we take out 30 frames in a second in normal, but in Time Lapse, only one frame comes out in one second, which means that when you take out a 30-second video, you get one second of footage, that is why the video becomes very fast.

7. What is Ultrawide

Ultrawide means capturing maximum space in one frame, for example, when you go out for a walk with your whole family, everyone comes in one photo, then what do you do for that, you go back a little or you tell everyone whose picture you click to go back, but when you click that picture in the form of ultrawide angle, then you do not need to go anywhere, you can capture everyone in one frame by staying in one place.

8. What is ToF lens

TOF ka full form time-of-flight hota hai yeh sensor Counts the depth of the subject means that when you click an image, how far it is and how far is the background behind it, with the help of infra red, it detects the subject and keeps the subject in focus and makes the background out of focus, so that we can see the pictures very clearly.

9. What is a macro lens? What Is MACRO Lens

A macro lens is a special type of camera lens that works with a very short focal length that captures very small objects very closely, for example when you are photographing an insect or insect. Photos If you want to show it closely, then you can do it through a macro lens, its minimum focus distance is about 30 cm.

10. What is ISO

ISO means how sensitive the sensor of your camera is to light, it means that if the ISO is low ie 100 or 200 then it is less sensitive to light, on the contrary if the number of ISO is very high like 2400, 3000 etc. then it will be more sensitive to light.

The picture taken by ISO mode depends on where you are and in what kind of light. image If you increase the ISO number to capture the image in more light, then your image will appear very bright.
