Why is the bulge on the phone’s camera getting thicker? Read the explanation – Student Zone

ipadguides.id – Hello, Zone Friends! As the title implies, Mimin wants to review technology-related things with you, more specifically about the cell phone that you currently hold or the ones you often see around. If we pay attention, some of the latest mobile phone outputs have a bulge on the camera or what is called a camera bump which is getting thicker.

Presence camera bump like this makes the surface of the back of the phone not parallel. The phone will not be able to be placed perfectly on a flat surface. In fact, not infrequently users will wrap their cellphones with accessories case so that the thickness of the camera bulge looks parallel to the back of the phone.

Then, why should there be a camera bulge? Check out the following explanation.

Focal Length for Mobile Photography

Launching from KompasTekno, most of today’s cellphones are equipped with capable photography features, usually having a fairly thick camera bump. Call it the Samsung Galaxy S21 Ultra, iPhone 12 Pro, Mi 10T Pro, Huawei P40 Pro Plus, Vivo X50 Pro, and so on.

The protrusion of the camera in various smartphones is due to the presence of one of the core elements in the camera component, namely the width of the lens or focal length. Simply put, the focal length determines how wide the camera lens can “see” the object being shot at.

The greater the focal length, the narrower the object viewed by the camera, and vice versa. Let’s take the example of a row of rear camera lenses, for example, with a resolution of 108 MP and a focal length of 24mm. Normal camera lenses themselves usually range in the number 35-50mm, so this lens can be called a wide lens.

On the other hand, the 12 MP ultrawide camera on the phone has a smaller focal length of 13mm. Therefore, this camera can shoot objects with a wider angle of view than the main camera. These two cameras may not have much impact on the thickness of the camera bump.

However, it’s a different story with the other two rear cameras that have a remote shooting function, aka telephoto. Due to the object magnification technique, the cellphone camera is equipped with two telephoto cameras, each with a 10 MP resolution with different focal lengths, namely 70mm and 240mm.

The first telephoto camera with a focal length of 70mm has an optical zoom capability of up to 3x, while the other is 10x. Normally, on a professional camera (DSLR), telephoto capabilities usually rely on a physical lens whose focal length varies, ranging from 70-200mm.

With one lens, users can extend the lens to a maximum focal length (200mm) for photographing objects from a distance, or shorten the lens to 70mm for objects that are not too far away. That is, the farther the distance from the lens to the image sensor whose job is to absorb light, the closer the object to be seen will be, and vice versa. In photography, this technique is called magnification or object enlargement.

Applying “Camera Lens” to Smartphone

Conventional telephoto camera mechanisms like this will not work for smartphones that are getting thinner and lighter by the day. In addition, the lens that extends forward also has the potential to reduce the aesthetics of the phone.

The solution, smartphone vendors package it with various image enlargement techniques, one of which adopts the periscope camera technique commonly used on submarines.

With a periscope camera, the telephoto lens does not need to extend forward and can be positioned sideways, as illustrated by the Huawei P40 Pro Plus periscope lens. The light that enters the camera lens will be reflected in such a way before it hits the image sensor.

This light reflection relies on prismatic glass and can provide an optimal image magnification effect of up to 100x, when referring to Huawei’s claims. As a result, the module with a working mechanism that looks complicated and this “stacked” arrangement may have an effect on the size of the camera bump.

Image Sensor Size Affects Camera Bump Size

In addition to focal length, the size of the image sensor can also have an effect on the size of the camera protrusion, as summarized by KompasTekno from AndroidAuthority, Tuesday (9/2/2021). This is the reason why cameras with large protrusions are usually more capable. This is because large sensors can actually absorb more light and improve image quality.

However, there is no official explanation as to why the smartphone camera is protruding beyond the surface of the shell. However, various factors related to the “simplified” conventional camera mechanism may be the main reason.

Alright, Zone Buddy! That’s all the explanation from Mimin regarding the camera bulge on the latest cellphones that are getting thicker. The essence of the explanation is that the camera features on mobile devices can more or less adapt the lenses on conventional cameras.
