EETimes published Samsung white paper "
CMOS Image Sensor: Current Status and Future Perspectives" by Seok-Hee Hwang. The paper talks about image sensor trends for mobile, DSC, DSLRs and automotive applications.
Mobile sensors trend is a pixel shrink while maintaining the performance by advanced processing, such as BSI, new color filters, etc.:
 |
| Pixel and process evolution in Samsung |
 |
| Sensitivity trend versus pixel size |
 |
(a) light loss ratio at each component
(b) spectral response of Samsung 6th and 7th generation CF |
 |
| Camera module temperature vs power density for CIS SOC type |
Not that much said about DSC trends. DSLR sensors use 130nm and 180nm process and, possibly, offer global shutter in future. Automotive sensor adoption is expected to be driven by many safety laws:

In the end paper talks about different automotive interfaces and importance of HDR. All in all, it's quite interesting and easy read targeted to wide audience.
