64 MP OmniVision sensor for smartphone cameras

23.10.2020

OmniVision, the world's third largest camera sensor manufacturer, has launched a new OV64A sensor with even larger 1µm pixels. The sensor is characterized by a resolution of 64 megapixels and a diagonal of 1 / 1,3 inches.

The new OmniVision OV64A sensor can be used in wide-angle and ultra-wide-angle smartphone cameras. Its larger pixels are 60% more sensitive to light compared to 0,8 micron pixels. Thus, the new sensor can provide better shooting in low light conditions. A 4-cell Bayer color filter is used for pixel placement.

When shooting still images and recording 4K video, four adjacent pixels can be combined into one larger 2µm pixel to capture even more light. In this mode, the resolution of photos is reduced to 16 megapixels. It is also noted that the sensor can be used to record video in 8K resolution at 30 frames per second, but without pixel binning. Video recording in 4K resolution is possible at up to 120 frames per second and with electronic image stabilization. In addition, 1080p/240 and 720/480 video recording modes are supported.

The OmniVision OV64A sensor also boasts dual and triple exposure HDR support. The device contains its own computing hardware resources, which are responsible for processing triple exposure, 4-cell HDR and tone mapping. This processing is faster than being sent to the smartphone's chipset for processing in the SoC, reducing motion artifacts.

Mass production of the new OmniVision OV64A sensor should begin this year.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Relativistic contraction of the electric field 02.12.2022

Scientists at Osaka University's Institute of Laser Engineering have used ultra-fast electro-optical measurements for the first time to visualize the contraction of the electric field surrounding an electron beam traveling at near-light speed and demonstrated the generation process.

According to the theory of relativity, to accurately describe the movement of objects flying past the observer at a speed close to the speed of light, it is necessary to use the "Lorentz transformation", which combines spatial and temporal coordinates. The Dutch physicist was able to explain how these transformations lead to self-consistent equations for electric and magnetic fields.

Although the various effects of relativity have been proven many times with a very high degree of experimental accuracy, there are still parts of the general theory of relativity (including special relativity) that have yet to be revealed in experiments. Oddly enough, electric field compression is one of them: the modern understanding of electromagnetism is based on the principles of Einsteinian physics.

Now, a research team at Osaka University has demonstrated this effect experimentally for the first time. They measured 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-optical sampling, they were able to register the electric field with extremely high temporal resolution.

Previously, the Lorentz transformations of time and space, as well as energy and momentum, were demonstrated in experiments on time dilation and rest-mass energy, respectively. Then physicists considered a similar relativistic effect, which corresponds to the Lorentz transformation of electromagnetic potentials.

In addition, the team observed the process of electric field compression immediately after the electron beam passed through the metal plate.
