Samsung Electronics has launched two new high-resolution image sensors that are destined for multi-camera arrays in smartphones. The two “Isocell” sensors – a 48-megapixel and a 32-megapixel unit both feature small size 0.8 micron pixels and are crucially compact to fit the slim bodies demanded of smartphone makers. Called GM1 and GD1 respectively, the two new sensors feature Samsung’s Isocell Plus technology which adopts an innovative pixel structure that improves both light sensitivity and color fidelity, and what Samsung are calling Tetracell technology where the output from four pixels is combined into one (oversampled) for reduced noise. The sensors also support the gyro-based electronic image stabilization (EIS) tech used in…
