Everyone knows that before the new smartphone was released, a large wave of publicity about the upgrade of mobile phone performance and the launch of new functions was indispensable. In recent years, with the increase in people's attention to the "freedom of taking photos" of mobile phones, mobile phone manufacturers have officially embarked on the road of mobile phone pixel " inverted ".
From the original 110-megapixels equipped with a CCD camera represented by the traditional key phone Sharp J-SH04, to the first 10-megapixel phone released by Samsung , to the 48-megapixel and 64-megapixels standard for smartphones today.
Until the launch of Xiaomi CC Pro in 2019, the pixels of the smartphone successfully knocked on the "door" of 100 million pixels. It is worth noting that recently, after 100 million pixels, Xiaomi launched the 200 million pixels 12T Pro, becoming Xiaomi's first 200 million pixel model.
"crossing" from tens of thousands to tens of millions of pixels,
from tens of thousands to hundreds of millions of pixels, and then to hundreds of millions of pixels. The "road to upgrade" of mobile phone pixels has attracted attention for more than 20 years. At this time, someone asked, since mobile phone pixels have reached such a high level, then having a smartphone with high pixels can achieve "freedom of taking photos".
In this way, for most consumers, the existence of cameras does not seem to be very significant. So much so that there are endless topics about "smartphones have become the biggest competitor of SLR cameras".
Recently, Judd Heape, vice president of camera product management at Qualcomm, said in an interview, "Due to the innovation of artificial intelligence technology, smartphones will surpass SLR cameras in the next three to five years and effectively eliminate them."
Can smartphones successfully eliminate cameras with high pixels?
In fact, from the perspective of pixels alone, there is no difference in the number of pixels for the photos taken by a smartphone and a camera, but if you pursue picture quality, there is a "world of difference" between smartphones and cameras with the same pixel logo.
Because the quality of the photo is good or bad, to a certain extent, it is determined by the core component photosensitive element . The photosensitive element is responsible for recording the collected light information. The larger the size of the photosensitive element, the more light information it can receive, and the details of the photo will be clearer. Just like what we say in daily life, "The larger the size of the photosensitive element, the more confidence you have to take a good photo." Therefore, the filming effect of a camera with a larger size photosensitive element is naturally better than that of a mobile phone.
However, as CMOS becomes the mainstream image sensor on the market, coupled with the rapid advancement of algorithm proofreading technology, the performance of mobile phone sensors has also been greatly improved. It is reflected in the shooting screen, and the image quality has also been improved by a "level".
For mobile phone manufacturers, it is not enough to improve the image quality. In the past two years, people have low desire to replace phones and prolong the replacement cycle, if they want to stimulate people's desire to buy phones, if one camera is not enough, two will come. If two still look down on them, three will come.
Therefore, in the current smartphone market, it is difficult to see a mobile phone with only one camera.
Take Xiaomi's 200-pixel flagship 12T Pro for overseas markets. The three cameras are "standard" and use Samsung ISOCELL HP1 sensor, with the main camera of 200 million pixels, and the other two lenses are 2 million pixels macro and 8 million pixels ultra-wide-angle lenses respectively. This camera configuration is indeed quite high.
But just like the number of pixels in mobile phones that are infinitely enlarged, the highest pixel they advertise for taking photos needs to be achieved under specific conditions. Most daily photos are displayed in "multi-pixel integration".
Therefore, in daily life, it is not surprising that only 1200W pixel photos are taken with a 100 million pixel mobile phone. The output of a high-quality photo is not only related to pixels, but also the composition, light and shadow plus the photographer's own technology.
The current shooting effect of smartphones can meet the daily needs of most consumers, but for professional photography, a "scrupulous" camera is essential because the picture under the camera can restore more details and colors.
After all, the camera's photosensitive element size is 7 times that of mobile phones, which is a reality that mobile phone hardware is difficult to change. But it has to be admitted that today's smartphones have made a qualitative leap in their photography effects with the help of the "magic" of algorithms. To a certain extent, we have indeed achieved the "freedom of taking pictures" of smartphones, but if we want to eliminate the camera, it is not enough.
