Why the iPhone still has that 12 megapixel camera

Although there is a 108 megapixel camera smartphone in the market, the iPhone still uses that 12 megapixel camera. The same goes for Google's Pixel series smartphones. The main reason for this is that 12 megapixels is ideal for the camera sensor of a smartphone. There are several reasons for this. There is the matter of storage. There is also a matter of time required in image processing. Brands also have to keep in mind to take good pictures in low light. Other than that, there are not enough devices to watch high resolution pictures or videos. It also comes with less direct issues like battery life and camera apps.
More megapixels means more data, more data means more storage
The more megapixels the camera has, the more data the smartphone has to process. This slows down the phone, draining the battery faster. And it takes more time to process pictures taken in night mode or portrait mode. Apart from that, more megapixel images have higher resolution. This increases the size of the image file. Memory card consumes more space. Again, uploading somewhere costs more bandwidth. Not all phones have the opportunity to add additional memory card slots.

The chances of seeing more megapixel pictures are less
Another fact is important to keep in mind here. No matter how many megapixels we take pictures, we rarely get a chance to see them. If you have an Ultra HD resolution TV in the house, you can see a picture or video of 6.3 megapixels. That means a 12-megapixel camera is more than enough for viewing on almost all types of displays. If you want to see the image of 12 megapixel camera in full resolution on Ultra HD display, you have to zoom in. Most of the Ultra HD Four resolution videos can be seen on the smartphone. Older phones do not have that opportunity. And 12 megapixels is more than enough to capture Ultra HD video

Many people pay attention to the camera when buying an iPhone. Although it is 12 megapixels, it is not a complaint

With the Qualcomm Snapdragon 65 SOC chipset, the opportunity to capture video has just arrived. However, the display is not yet available to watch the video. And if you record video in 8K resolution, there will be a big storage crisis.
Resolution is not all
Camera resolution is not everything. There are many more issues. The iPhone 12, which came on the market in 2015, was the first camera with a 12-megapixel sensor. That is it now. But if you compare the pictures taken with the iPhone 12 Pro camera with the iPhone 8S, you will find the difference day and night. It has been possible to improve the hardware and software.

Software is very important
The phrase ‘AI camera’ is often heard lately. Whether it is Google, Apple or other organizations, the final quality of the image taken on the smartphone depends on the image processing software.

It is important to keep in mind the size of the sensor
The problem with increasing the number of megapixels by keeping the size of the sensor the same is that the size of each pixel becomes smaller. And if the pixels are small, it can hold less light, there is a risk of increasing the noise. On the other hand, the larger the size of the sensor, the more light can enter the camera to take pictures. And the more light, the better the picture. Because, this light fixes the exposure balance, dynamic range, and even sharpness of the camera.

For now, 12 megapixels is enough
When a smartphone comes with a more powerful processor, more storage, a smartphone with a camera of more than 40 megapixels may be needed. Now there is no opportunity to watch that quality picture or video. So currently 12 megapixels is enough. And with that in mind, the iPhone still uses a 12-megapixel camera. The amount of megapixels will also be increased when needed.
