The forward facing systems has good processing capacities integrated into them so even though it may incure a high cost, it may be helpful.

This is an intriguing preview of BMW rear camera teardown.  What would be more interesting would be a full teardown analysis on forward facing camera modules, especially those with stereo vision and/ or sensor fusion (radar or LIDAR combined with vision) capability.  The forward facing systems have much more processing capabilities integrated into them and therefore the silicon content will be more exciting to unveil and dissect.

While cost is always a good topic for such articles, I am not seeing technical details and discussion how costs were driven or could be lower so the EE time's reads can learn from the article

I am unable extract if its an NTSC analog camera (VERY LIKELY) Vs digital and how one can add value in future designs both in terms of low light sensitivity, noise and transmission method e.g next gen's bird's eye view and distance processing

Building a DVR with a reversing camera only has very little value and thus 4 corner camera with image stitching and possibly de-warping necessary but lot more intelligence needed in terms of compression, access to GPS, G force sensors,  FLASH storage and retrieval

Cost is also subjective as its vol and relationship driven between vendors and not just the parts cost. Though for such a simple analog camera, I would be surprised if its BOM including testing and assembly costs> $20

Where's the mini-DVR . . . so the insurance company can see who you ran over?

@_hm we only cost the discrete device and we use a methodology of the parts at high volume. This is based on our work on electronics in the consumer space. I trust you can appreciate pricing from the outside in and the assumptions you have to make. Given we don't have an inside view of the books here has to be an assumption of a certain volume. We publish our costing methodology at Teardown.com

It is not only OmniVision sensor and two more chips. Optical lens and other remote processing, display electronics and connecting harness are also important. They all add up cost. Do you add them?

You also need to add design and development cost to it. It takes lots of effort to design, develop and test.

Final part is procurement and assembly. If you add all them together, it does not have that high margin. This is low volume device.

michigan0 Sang Kim First, 28nm bulk is in volume manufacturing for several years by the major semiconductor companies but not 28nm FDSOI today yet. Why not? Simply because unlike 28nm bulk the LDD(Lightly Doped Drain) to minimize hot carrier generation can't be implemented in 28nm FDSOI. Furthermore, hot carrier reliability becomes worse with scaling, That is the major reason why 28nm FDSOI is not manufacturable today and will not be. Second, how can you suppress the leakage currents from such ultra short 7nm due to the short channel effects? How thin SOI thickness is required to prevent punch-through of un-dopped 7nm FDSOI? Possibly less than 4nm. Depositing such an ultra thin film less then 4nm filum uniformly and reliably over 12" wafers at the manufacturing line is extremely difficult or not even manufacturable. If not manufacturable, the 7nm FDSOI debate is over!Third, what happens when hot carriers are generated near the drain at normal operation of 7nm FDSOI? Electrons go to the positively biased drain with no harm but where the holes to go? The holes can't go to the substrate because of the thin BOX layer. Some holes may become trapped at the BOX layer causing Vt shift. However, the vast majority of holes drift through the the un-dopped SOI channel toward the N+Source,...
