Image sensor technologies have been advanced drastically these 4 decades, and they have brought fruitful success in the market. The sales amount was more than 4 billion pieces in 2015. In this presentation, pixel shrinkage trend and recent technical trends at visible image sensors are reviewed:
1. pixel shrinkage,
2. photon counting,
3. stack and 3D structure,
4. sensitivity expansion to invisible, especially near IR,
5. ToF (time of flight) and gesture.
