Rumor: Samsung invented a superb camera tech for Galaxy phones
Samsung could soon launch a breakthrough in smartphone camera technology. Future Galaxy phones may be equipped with an advanced Samsung camera sensor with a global shutter, replacing the legacy solution.
According to SisaJournal (via Jukan), Samsung has developed global shutter camera technology for future Galaxy phones. The new solution is slated to be utilized in place of the conventional rolling shutter sensor tech.
The report claims that the company is focusing on the development of a global shutter-level image sensor. The target is to utilize the next-gen image sensor shutter technology in the future flagship smartphones.
Global shutter camera
The new sensor features a new pixel structure and algorithm tech based on rolling shutter hardware. Thanks to the mix and match of new and mature solutions, the sensor has become advantageous for high-res implementation.
Samsung applied a new pixel structure to a 1.5µm pixel pitch with a 12MP-class lens and managed to realize global shutter-level shooting features.
The company has designed a new analysis engine that features an Analog-to-Digital Converter included in the Pixel Level ADC. This would have taken the pixel size to 3µm, double the basic size used in smartphones.
Samsung kept the actual physical pixel at 1.5µm size but made it into a ‘2×2’ bundle form so that a 3µm pixel unit could be used as the basic unit digitally.
A Samsung Electronics official familiar with the related technology said, “It is a structure where 4 pixels share one ADC; in this case, only the part corresponding to 2×2 operates sequentially like a rolling shutter, and the rest can operate as a global shutter.”
What next?
Smartphone cameras require higher resolution, making the global shutters difficult to use. However, the new shutter mechanism has plenty of advantages, including the ability to accurately capture fast-moving subjects.
Apple also reportedly wants a global shutter to be used in its future iPhone camera. The iPhone maker is also pushing Samsung to innovate the tech. Samsung seems to have achieved a satisfactory level of implementation.
Rolling shutter cameras usually fail in accurately capturing moving objects. However, the global shutter sensor can capture fast movements. It captures the entire frame at once, and it captures high-speed subjects like a still screen.
The development has reportedly been completed, but refinements would still be made. The company will explore ways to further optimize the new camera before commercializing it with the future Galaxy S series phones.
The official continued, “However, since rolling shutter operation is included, there is slight image distortion, so it cannot be seen as a perfect global shutter,” adding, “We extracted optical flow (brightness change of each pixel within the image when the camera or subject moves) from this and performed motion compensation. By applying that including the algorithm, a high-resolution image sensor with global shutter characteristics became possible even at a very small pixel pitch.”
Samsung plans to officially present specific details early next year.
