SmartSens, a Chinese CMOS manufacturer, has unveiled its latest smartphone image sensor, the SC580XS, which comes with several key improvements over its predecessor, the SC550XS. This compact 1/1.28-inch sensor offers enhanced features and capabilities, positioning SmartSens competitively in the smartphone image sensor market, alongside major players like Sony, Samsung, and OmniVision.

SmartSens SC580XS Key Features:

The SC580XS stands out with its 50-megapixel resolution and 1/1.28-inch optical format, a step up from the earlier 1/1.56-inch SC550XS model. It utilizes the same 22nm HKMG Stack process but with several key improvements. The sensor boasts a pixel size of 1.22µm, but in a four-in-one mode, this effectively increases to 2.44µm, which is pivotal for high-quality video recording. This feature allows the SC580XS to support 4K video at an impressive 120fps, making it ideal for advanced smartphone camera applications.

The SC580XS achieves a low readout noise of 0.7e-, which, combined with its correlated multiple sampling technology, enables a substantial reduction in noise by up to 40%. This results in clearer images, especially in low-light conditions. Compared to similar sensors in the industry, the SC580XS offers a significant reduction in both readout noise and fixed pattern noise.

The image sensor also stands out for its PixGain HDR technology, greatly enhancing the dynamic range to 120dB. This feature reduces motion artifacts, ideal for capturing fast-moving subjects. The sensor also supports multiple HDR modes, including triple exposure HDR and PixGain HDR+VS, further enhancing image quality in diverse lighting conditions.

Whether you’re capturing a fleeting moment or snapping a group selfie, fast and accurate autofocus is essential. The sensor offers enhanced focusing capabilities through AllPix ADAF and Sparse PDAF technologies, ensuring quick and accurate focusing in various lighting conditions. Additionally, the sensor prioritizes energy efficiency with improved readout circuitry and the 22nm HKMG process, allowing for extended smartphone use without excessive battery drain.

SmartSens has announced that the SC580XS is currently available for sampling and is expected to enter mass production in the first quarter of 2024.
