Small image sensors enhance sharpness in smartphone cameras

Two 0.8-micrometer pixel image sensors have been announced by Samsung. The 48Mpixel Isocell Bright GM1 and the 32Mpixel Isocell Bright GD1.

Cameras are becoming a distinguishing feature in today’s mobile devices, presenting smartphone makers with the challenge to fit multiple cameras into sleek designs. The Isocell Bright GM1 and Isocell Bright GD1 have a reduced pixel size for greater design flexibility, enabling camera module manufacturers to build smaller modules or pack more pixels into existing designs, and allowing smartphone makers to maximise space in the slim, bezel-less smartphones.

The GM1 and the GD1 sensors are based on the company’s latest pixel isolation technology, Isocell Plus, which optimises performance especially for smaller-dimension pixels, making them suitable for today’s super-resolution cameras. Additionally, Tetracell technology, where four pixels are merged to work as one to increase light sensitivity, enables the GM1 and GD1 to deliver light sensitivity equivalent to that of a 1.6μm-pixel image sensor at 12Mpixel and 8Mpixel resolution, respectively. The sensors also support gyro-based electronic image stabilisation (EIS) for fast and accurate image capture.

A real-time high dynamic range (HDR) feature in the GD1 delivers more balanced exposure, richer colour and detail when filming selfie-videos or streaming live video content even in low-light, high-contrast environments, says Samsung.

The Samsung Isocell Bright GM1 and GD1 are expected to be in mass production in Q4 2018.
