The 48 MP ISOCELL Bright GM1 and 32 MP ISOCELL Bright GD1 are Samsung's new 0.8-micrometer image sensors for mobile devices that enable camera module manufacturers to build smaller modules or cram more pixels into existing designs. These sensors support Gyro-based image stabilization and the Tetracell technology for increased light sensitivity.
