 Friends, what is a camera? a camera is an optical instrument for recording or capturing images, which may be stored locally, transmitted to another location, or both. now days every smartphones contain cameras. when we try to compare two smartphone cameras, there are many terms in the specification that many terms, which are difficult to compare without having a good knowledge of terms. So today's post is going to discuss all the terms with the camera and the details about them. Read the post carefully, hopefully learn a lot about new topics.

                                          Camera sensor

 See, the most important part of any camera is the sensor. There are usually two types of sensors available on mobile phones, one is CMOS and another is BSI. BSI sensor is slightly better in terms of low light performance compared to the simos sensor. And above all, you create a blinking image. The BSI sensor is flipped, so the light that is inserted on the camera goes behind the sensor and the light reflects very low so the image quality can be seen.There is another term in the sensor, which is also very important, that is the sensor size. See, there is a number to describe each sensor size. Such as 1 / 2.3, 1/2.6 etc. So easy to understand that the number of numbers with 1 fraction should be as small as the size of your sensor. And your sensor size is bigger than big pixels and you'll find. And the larger the pixels, the image will be even more enlightened and shiny.

                                                 Aperture

Let's talk about the aperture. You may have noticed that the aperture of the camera is displayed by f / 1.8, f / 2.0, f / 2.2, etc. But what are these actually? See the lower hand F's in this number is the focal length of your camera lens. And the number below is that the opening of your camera means that the holes in the camera through which the light enters the camera, the diagram of it. This number is basically a resiao between the focal length of your lens and the opening of the camera. It has the option of manually adjusting the large DSLR cameras. But it will not be able to manually adjust the mobile phone. That is, the aperture available to the company is always the default.An easy thing to do is to know which aperture is better, see the number of numbers after the F-fraction in the aperture number, the smaller the opening, the opening of your camera will be larger. And the opening will be as big as your camera will be able to lift low light photos. And there is also a sleek defied off field effect that can be seen well. Hello Deafat of Field Effect, you might have noticed that the pictures of the subject are clear while you are taking pictures and there is a dark background behind the subject, so the lesser the aperture number of your camera can be found to be as good as the effect.

Friends, let's talk about the lens. Seeing the truth is that lens is not an important factor in comparing cameras today. Generally, there are 5 element lenses or 6 element lenses available on mobile phones. Some mobile phones also use the name of a large brand lens, such as sniper optics or Carl Jeis Optics. So actually the lens is not an important thing, and it is a little difficult to compare so you can even ignore this issue.

                                           Camera OIS

 Let's talk about the camera's OIS technology. I'll post a separate post detailing the OIS once. Now let's know about some basic things. See if there is a lot of time, your hand may be slightly curled when the photo is taken, so the picture becomes dark. But if you have an OIS feature on your camera, it can be possible to get good pictures even if you have a hand. Apart from this you will also see low light performance as well. Again, when recording the video, due to OIS, there is a steady video recording without the recording cascade. So it is a good thing to have OIS in your camera. If you have OIS in your camera, it's a benefit for you.

                                            Focus Technology

You've probably heard many names about focus technology. Such as Laser Auto Focus, Phase Detection Auto Focus, And General Auto Focus Now Laser Auto Focus is the most advanced technology among these three focus technologies. Laser Auto Focus is a small part of your phone's camera. It spreads many laser beams together in a big area. And these beams came back after pushing the subject in front of the subject. Imagine you have got auto focus of laser in front. Now, some of the beam out of this focus will be shocked with your body and some beam will get back to you by pushing the environment behind you. Your phone determines the actual position of the subject depending on the distance between these two types of beam and the time it is returned. And accordingly, it helps to move a camera image and move a focused image. In the same way when you tap on focus on a laser auto-focus phone, you can tap your phone's laser where you tap on the camera. Beam throws the ball. Again, depending on the time of the return of the bim, it determines the distance of the object and helps to focus the focus of the camera lens on it.Now let's talk about the phase Detection Auto Focus. Phase Detection Auto Focus is available in iPhone and Samsung. What happens, see the sensor on your phone that detects the phase of incompleting light from the object. This means that the object that comes in front of the camera when it comes to the camera depends on the light to lock the focus.Now let's talk about the general auto focus that can be seen in almost all the normal cameras. See it's a contrast based technology. It tries to focus on the contrast level between you and your background. It does not have any laser beam or phase detection technology. It will focus when you want to focus on tap. Sometimes it's a little late to focus on. Again, it fires flash to make better focus in low light. Kona Low Lite is quite difficult to focus on contrast. Because of this, it illuminated the environment by flashing it and filling the image to remove the image.

                                             Flash

                                                         Source

There are three types of flash in the camera flash. Single LED flash, dual LED flash, and dual tone flash. Earlier on some Nokia phones and on Sony's phone Xenon Flash could be seen, but today it is not visible anymore. See, single LED flash means that it has an LED. When you flash, this one will produce its lights and you will get the picture. Dual LED flash means that there are two LEDs, so you will see more light in the flash.Two LEDs are fitted with dual tone flash, but the color of the two leds is different. One is a type of cool type, bluish and the other is a worm type ie Yolosis. This flash produces a color based on its light and mixing it together in two light colors, and you see a natural photo.

                                          Image Processing

                                                          Source

 The image processing system is an important thing for each camera. It's not a device but it's a software. Different Alda Company uses different technologies for image processing. As Apple's image processing software is much better, the phone may not have more options for the camera, the same timer set Flash on Off. But whenever you take photos, Apple processes that photo so well that the output comes very well.Samsung's phones found that the image was more colorful when the image was processing. Sony and LG phones make their images much sharper, so that no natural images can be seen. Image processing is basically a system where bad images can be made better and if your camera has a lot of good parts but your image processing system is not as good then you will not see good image output. That's why, if all the specification of two smartphone cameras is the same, but if the image processing system is different, then the two phones will not be able to remove the picture in one way.

Last word

Hopefully, after reading this post, you can select your new camera phone as it is and you can compare it very well with other phone cameras. If you need to see the reviews of the phones, then see which aperture is good, the image processing software is good and take care of these issues and purchase your new phone. However, if you like the post or share your benefits, please share it and comment on any type of question.
