Light Field Forum notices a recently published SK Hynix patent application US20170179180 "
Light Field Imaging Device and Method for Fabricating the Same" by Jong Eun Kim proposing the integration of the whole light field system in the microlens stack:
Very impressive structure for the light field sensor, does it proved in commercial sample?
ReplyDeleteCan someone explain what this innovation is?
ReplyDeleteWhat's a light field sensor?
How is this an innovation? The fact that there are 2 microlenses of different size stacked on the sensor, if so why would you want a large microlens on top of smaller microlenses, what's the benefit?
You can measure the amount of light entering the larger microlens as a function of angle. The sum is the same, but having angle information allows addition scene information to be extracted computationally. See Light Field Camera...
