Samsung Develops New Camera Sensor with Global Shutter Technology, Possibly for Future Flagships
Table of Contents
Samsung is reportedly developing a new camera sensor featuring global shutter technology, a significant advancement that could dramatically improve image and video quality, particularly when capturing fast-moving subjects. This development, first reported by GSMArena, suggests a potential leap forward in smartphone camera capabilities, moving beyond the limitations of customary rolling shutter sensors.
Understanding Rolling vs. Global Shutter
Most smartphone cameras utilize a rolling shutter. This technology captures an image line by line, sequentially. While effective in many situations, it struggles with fast motion.This sequential capture leads to distortions when photographing moving objects, resulting in phenomena like leaning buildings, stretched car wheels, or blurred limbs of runners.These artifacts occur because the different parts of the image are captured at slightly different moments in time.
Global shutter overcomes this limitation by capturing all pixels concurrently, in a single moment. This results in sharp, distortion-free images and videos, even with rapidly moving subjects. This is why global shutter technology is currently prevalent in professional cameras used for sports broadcasting and industrial quality control applications where accurate representation of motion is critical. Sony Semiconductor Solutions provides detailed information on the benefits and applications of global shutter technology.
Sensor Specifications and Potential Applications
The leaked specifications indicate the new Samsung sensor will feature 12 megapixels with 1.5 µm pixels arranged in a 2×2 formation. The relatively lower resolution, compared to some flagship smartphone sensors exceeding 100 megapixels, suggests this sensor is likely intended for a telephoto lens or ultra-wide-angle sensor, rather than the primary camera.
A key innovation is the integration of an analog-to-digital converter (ADC) directly within each pixel. This on-pixel ADC promises faster image processing, a crucial requirement for the speed of a global shutter sensor to read all pixels simultaneously. Samsung’s website details their advancements in image sensor technology, though specific details on this new sensor are not yet publicly available.
Why is Global Shutter Critically important for Smartphones?
The inclusion of global shutter in smartphones would represent a significant improvement in video recording, particularly for users who frequently capture action shots or videos. It would eliminate the “jello effect” commonly seen in smartphone videos of fast-moving scenes and provide more accurate and stable footage. Beyond consumer applications, it could also enhance features like augmented reality (AR) and object tracking.
