The South Korean company "Samsung" revealed a new sensor for phone cameras, which works with a accuracy of 50 megapixels, indicating that it represents an important development in the world of smartphone photography, as it combines simultaneously for the first time between the two latest technologies in the world of digital photography, and makes them work Together inside a single system, the DEPAF technology for dual-focus autofocus, which allows focus on the target without the need to zoom in or zoom out of the lens, and thus ultrafast imaging, and the Tetra Cell technology to collect "pixels", which can collect target signals and data From four "pixels" Jealousy together and deal with them as one large, allowing the goal to discover and focus on it from the four corners together at the same moment, pick up very image clarity.
GNI
"Samsung" said in a statement about this development, published on the newsroom on its official website, that the new sensor, called "GNI", is part of its commitment to users to provide smart phone cameras capable of producing amazing pictures in any environment, stressing that they You will continue to provide image sensor solutions on the latest technologies that will drive future trends in mobile photography.
Depaf
And provided «Samsung» clarifications on the two technologies that have been incorporated into the new sensor, indicating that the first technology is «dual pixel autofocus», known as “Depaf”, a technology that makes the function of focusing the lens on the target with the camera work automatically, and not by zooming in and out The lens, by rotating the hand that the cameraman was doing before taking the photo.
She added that the automatic focus is made, using a different use of what is known as a "pixel", or the smallest data-carrying unit in which the camera operates when taking a picture of the target, and its size is measured in microns, as the imaging sensors contain valves to receive "pixels", but some of these valves only Focus on the image function, and some of the image recording function.
Diode
And Samsung explained that in Depaf technology there is a diode that performs both functions simultaneously, where each diode has a separate lens above it, and when the light passes through these lenses and strikes the diodes, the processor responsible for operating the two valves analyzes the signal of each valve For focus, and once focus is achieved, the signals are then combined to record the image, and thus it focuses and records together in moments, allowing the task of focusing on the image to be accomplished automatically, without the need to adjust the lens by zooming in and out, and in this way the focus can be easily managed and switched between Goals while shooting, Quickly and accurately, get crystal clear results, especially when recording video.
Tetra Cell
As for the technology "Tetra Cell", "Samsung" mentioned in its statement a simple example to explain this technique, indicating that the imaging process is mainly based on capturing "pixels" or fine points, which represent the smallest unit of data carrying about the target to be photographed, which is in one way or another. Similar beads of rain drizzle, required to collect to get some water.
And she said: «Imagine that you want to collect the splashing rain spray, then there will be two paths in front of you, either placing a small vase that takes one raindrop pill, or placing a large vase that captures many rain beads together, and in both cases you have a measure of water, but in the second it gives you a clearer and more correct picture For direct use, in the first case you have to collect the beads in the small pots to reach the same result.
She added: «In this way, the technique of collecting“ pixels ”or“ Tetra Cell ”, which collects four pixels captured by the imaging sensor together and directly, creates a large“ pixel ”that allows obtaining a higher resolution and clearer about the target to be photographed. Noting that, purely from a technical point of view, Tetra Cell works to improve the camera's ability to capture and process more light, by grouping four "pixel" signals together for a single objective from four angles in one moment.
Amazing results
Some of the smartphone manufacturers are more focused on images with very high detail and accuracy, while others choose to focus on creating larger pixel units for bright results in environments, said Samsung's vice president of sensor business, Yongin Park. Low light.
He added that the new sensor from "Samsung" can do both, as it brings together the technology "Depaf" and "Tetra Cell" together, and then it achieves amazing results, and a new level of performance and sensitivity to light, when taking stellar images with low illumination, as well as in Autofocus speeds, which bring the performance of smartphone cameras to the refineries of the professional, expensive, stand-alone professional cameras.
