Will smartphones do away with cameras?

Published

on

How many people do you see on the street with a special camera in their hands? Probably very few, especially since smartphones have begun to offer shooting quality at least comparable to a DSLR.

However, in terms of quality, despite the great strides made by Apple, Samsung, Xiaomi, Huawei, Vivo, Oppo, etc., the truth is that a good camera still outperforms any high-end smartphone. At least for a while!

Do smartphones have what it takes to complete the cameras?

Thus, Sony is no longer the only giant in the mobile technology world who believes that smartphones have what it takes to surpass the image quality of digital SLR cameras in the near future. After all, Judd Heap, VP of Camera Product Management at Qualcomm, seems to share a very similar sentiment. You know why?

Because the capabilities of sensors continue to grow, and in fact the level of development and innovation in this area is much higher than in the rest of the photographic industry.

What’s the secret?

Apparently, the potential lies in the level of processing that exists in the world of smartphones, especially in the higher ranges. After all, compared to the most powerful cameras on the shelves, be it Sony, Canon or Nikon, any high-end smartphone is at least 10 times more powerful in terms of processing power.

Computing power, which, as you understand, has only increased.

Big brands don’t want to fight smartphones.

As you may know, Canon has already announced the end of its DSLR lineup, and it looks like Nikon is joining the same train with its focus on mirrorless cameras.

In short, the greats of this world know that it is impossible to fight the practicality that smartphones offer.

So what about the megapixel war? This is an obstacle to evolution!

A Qualcomm expert believes that this new numbers war in the world of smartphones is useless, and that for a good development of the market, it would be a good idea to bet on sensors between 40 and 50MP.

A curious proposition, as Samsung will make a big and ugly 200MP bet from next year on its top of the range Galaxy S23 Ultra. Here we must take into account that more megapixels does not necessarily mean larger sensors. Pixels will be smaller, and for this reason, they may have difficulty getting light through. In the near future, it is very likely that the maximum sensor size for smartphones will not exceed one inch (1 inch).

Besides, what do you think of all this? Do you think that cameras will die, remaining only for professionals? Share your opinion with us in the comment box below.

Einstein’s complete theories are a breakthrough in particle physics

Einstein's complete theories are a breakthrough in particle physics

More than a century after its first appearance, scientists have completed Einstein’s homework on special relativity in electromagnetism.

Osaka University researchers demonstrate the relativistic contraction of the electric field generated by fast moving charged particles, as predicted by Einstein’s theory, which could help improve research in particle physics and radiation.

More than a century ago, one of the most famous modern physicists, Albert Einstein, proposed the revolutionary special relativity. Most of what we know about the universe is based on this theory, but some things have yet to be experimentally proven. scientists who Osaka University The Institute of Laser Technology was the first to use ultrafast electro-optical measurements to visualize the compression of an electric field around a beam of electrons moving at close to the speed of light and to demonstrate the generation process.

According to Einstein’s special theory of relativity, it is necessary to use the “Lorentz transformation”, which combines spatial and temporal coordinates to describe the movement of objects passing by the observer at a speed approaching the speed of light. He was able to explain how these transformations led to self-consistent equations for electric and magnetic fields.

Although the various effects of relativity have been proven many times with a high degree of experimentation[{” attribute=””>accuracy, there are still parts of relativity that have yet to be revealed in experiments. Ironically, one of these is the contraction of the electric field, which is represented as a special relativity phenomenon in electromagnetism.

Now, the research team at Osaka University has demonstrated this effect experimentally for the first time. They accomplished this feat by measuring the profile of the Coulomb field in space and time around a high-energy electron beam generated by a linear particle accelerator. Using ultrafast electro-optic sampling, they were able to record the electric field with extremely high temporal resolution.

It has been reported that the Lorentz transformations of time and space as well as those of energy and momentum were demonstrated by time dilation experiments and rest mass energy experiments, respectively. Here, the team looked at a similar relativistic effect called electric-field contraction, which corresponds to the Lorentz transformation of electromagnetic potentials.

“We visualized the contraction of an electric field around an electron beam propagating close to the speed of light,” says Professor Makoto Nakajima, the project leader. In addition, the team observed the process of electric-field contraction right after the electron beam passed through a metal boundary.

When developing the theory of relativity, it is said that Einstein used thought experiments to imagine what it would be like to ride on a wave of light. “There is something poetic about demonstrating the relativistic effect of electric fields more than 100 years after Einstein predicted it,” says Professor Nakajima. “Electric fields were a crucial element in the formation of the theory of relativity in the first place.”

This research, with observations matching closely to Einstein’s predictions of special relativity in electromagnetism, can serve as a platform for measurements of energetic particle beams and other experiments in high-energy physics.
