Should we be worried about the 200 megapixel camera of mobile phones?

Some users still haven't come to terms with 108 megapixel cameras, but now we have to prepare ourselves to face the spread of 200 megapixel cameras. Months ago, Samsung unveiled such a sensor, and Omnivision has recently developed such a sensor. Considering that the Galaxy S23 Ultra is likely to use a 200-megapixel camera, we will see the spread of such cameras much sooner than expected. But should we accept this trend or be worried about such a trend? We will discuss this issue further.

Some users still haven't come to terms with 108 megapixel cameras, but now we have to prepare ourselves to face the spread of 200 megapixel cameras. Months ago, Samsung unveiled such a sensor, and Omnivision has recently developed such a sensor. Considering that the Galaxy S23 Ultra is likely to use a 200-megapixel camera, we will see the spread of such cameras much sooner than expected. But should we accept this trend or be worried about such a trend? We will discuss this issue further.

Why should we accept the 200 megapixel camera?

First of all, it is better to point out the positive points of the case. The 200 megapixel sensor means that it can record a huge amount of information, and Omnivision and Samsung companies have repeatedly emphasized that such a thing leads to an increase in the resolution and attractiveness of photos and videos. However, the reality is that we need a 33-megapixel sensor for 8K videos, and on the other hand, despite the extensive advertising, 200-megapixel photos will not have the clarity and extraordinary quality.

So the resolution is not considered the most important point of strength of these sensors. On the other hand, we have to look at their capabilities. For example, the ability to combine pixels is one of the important features of such sensors. Omnivision and Samsung both offer 4 and 16 adjacent pixel combinations for their 200MP sensors. As you probably know, with this technology the size of the pixels increases virtually. Although the ability of these pixels to absorb light is not as high as the pixels that have this size in reality, in any case, we cannot hide the improvement of photo and video quality in low-light environments by using this method. Also, these new sensors have a lot to say in the field of auto focus.

Higher resolutions also require a higher bandwidth to transfer data to the phone's chip, and this bandwidth can be used to output a lower resolution at a lower rate. used a higher frame. For example, Omnivision's OVB0A sensor can deliver 200 megapixels at 8 frames per second, 50 megapixels at 30 frames per second, or 12.5 megapixels at 120 frames per second by combining pixels. This means that without the need to use special software, the desired sensor is capable of providing 8K output at 30 frames per second and 4K at 120 frames per second. It is also possible to shoot one after the other with a suitable resolution. Receipts are very important. For example, the Omnivision sensor can render 4K video based on 60 frames per second with two different exposures superimposed to capture more attractive HDR video. Of course, we should note that these problems are also solved by faster sensors based on lower resolution.

Why should we worry? 200 megapixel camera?

Like all technologies, there are some disadvantages and problems along with the advantages. The most important problem of 200 megapixel cameras is related to the small size of the pixels in their sensor. As a reminder, we must say that the smaller the sensor, the higher the image noise and the lower the dynamic range.

That is why even though all the companies want to improve the video quality in low light environments, Such a trend is against this demand - especially for 4K and 8K resolution. One of the important features of the camera sensor is its size. It should be noted that the 200-megapixel sensors are no bigger than the giant sensors currently in use. Currently, some phones use a 1-inch or similar camera sensor, which is considered a very large size for smartphones. Therefore, simply using a higher resolution does not solve many problems and challenges. There are exciting technologies under development that can solve important problems. For example, we can use Sony Xperia 1 Mark 4 is a periscopic camera based on variable focal length. Thanks to this feature, a sensor and a lens can offer more flexibility. Companies like Google and Oppo have also set aside a lot of budget for the development of dedicated image processing chips so that the camera in their phones has more to say in terms of image processing. We should also mention the progress in the field of image processing algorithms, which are getting smarter day by day.

Finally, whether we like it or not, in the near future the number of phones based on 200 megapixel cameras will increase significantly. . According to the available evidence, it seems that these sensors are mainly used to create noise and advertisements and are not going to significantly improve the quality of photos and videos. In the meantime, we're still looking forward to more advancements and improvements in mobile photography.
