OmniVision Image Sensors for Smartphones

11.11.2016

OmniVision Technologies announced the development of four new image sensors for smartphones that can capture more light and generate less image noise than ever before.

The new sensors will use second-generation OmniVision, PureCel Plus and PureCel Plus-S pixel technologies. The increase in the dynamic range of brightness compared to the previous generation will be 20%.

In addition, the company has created a completely new zHDR technology that allows you to expand the dynamic range of sensors using short and long exposures in one frame. The final image is obtained by intelligently combining the received data. Devices equipped with new image sensors will allow you to record video or view the image on the display in HDR mode in real time even before you take a picture.

The pixels in the new sensors will be arranged in such a way as to capture more light and reduce the amount of noise. The light sensitivity of the new sensors will be increased by 12,5%.

The sensors will have a resolution of 16 and 20 megapixels, they will appear in smartphones, which will begin production in the first quarter of next year.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

DDR4 memory 24.06.2014

In Japan, sets of DDR4 RAM have appeared on sale, the benefits of which will be the first to be appreciated by future owners of computers based on Intel Haswell-E processors and motherboards based on the Intel X99 chipset.

DDR4 specifications provide performance from 1,6 to 3,2 gigatransactions per second per pin. The supply voltage is 1,2 V, and the bandwidth reaches 34,1 GB / s. Compared to DDR3, in addition to speed, increased reliability.

DDR4 modules were demonstrated at the recent Computex 2014, and now the Japanese store Akiba PC Hotline has started accepting orders for them. DDR4-2133 products are manufactured by SanMax based on SKHynix microchips. The SMD4-U16G27H-21P-D set of two 8 GB modules each will cost $350, while the SMD4-U32G28H-21P-Q set of four 8 GB modules is priced at $685. The modules have 288 pins and operate at 1,2V.

It should be noted that the Intel Haswell-E processors and the X99 chipset will reportedly debut on September 14th. Therefore, those who decide to buy DDR4 RAM modules now will have to wait at least until the end of the third quarter to start their practical use.
