Don Scansen from reverse engineering company Semiconductor Insights published a market trends overview in Video/Imaging Designline.
Covering wide range of issues, from camera-module footprint and hight to price and ISP integration trade-offs, the article gives a birds-eye view on many controversial problems in image sensor design.
Some points to note:
- a modern image sensor process is almost twice more expensive than standard CMOS
- sensor-ISP integration is less cost-optimal than baseband-ISP integration in camera-phones
- 1MP camera-phone module costs about $7-8 to build.
