News and discussions about image sensors
Again one video from Rambus about this LSS technology... can someone explains me what are the actual key selling point(s) of this new type of lens-less sensor when one can actually buy VGA resolution full camera modules (with lens yes!) at prices of 0,2$US per unit today?
The difference is that you can 0.1$ lensless sensor but you have to pay a >100us$ deconvolution system, so it could generate more business... :)-
They provide advantages for 4th generation imaging applications (eye tracking, smart building, etc) over conventional lens systems.
Form factor --> Eye tracking for VR headsets where the footprint is significantly less than of lensesPrivacy --> For Smart building where you want to be able to detect how many people are and where they are located rather than motion and non motion events given by a simple PIR sensor. And without reconstruction, you can protect their privacy much better than a camera. Also much more economic than a Thermal Sensor.Point tracking --> LSS technology receives a pattern from a point, making it much more easier and more accurate to track points such as light reflection on eye for eye tracking compared to conventional cameras.

I am extremely skeptical about any commercial success of this type of AR glasses and this LSS technology...
I too am very skeptical about RAMBUS 'technology'. I don't see any real innovation here and it doesn't seem to make much sense. We already have very low profile high resolution image sensors for mobile phones. These produce high quality images at very low cost. Because they produce normal images we can use a very wide variety of standard image processing algorithms developed with matlab, openCV etc to suit any application we may have in mind. Why bother learrning about 'blob domains' and purchasing expensive boards. A waste of time in my opinion.
For general imaging application, LSS does not provide anything new. But for point tracking, capturing wide field of view in an extremely thin form factor, LSS is significantly superior to any lens system solution out there. This is again meant for 4th generation imaging application. This is not geared towards 3rd generation imaging.
