2013 Leti annual report has a collection of the last year's papers. The "New 3D-integrated burst image sensor architectures with in-situ A/D conversion" by R. Bonnard, F. Guellec, J. Segura, A. Dupret, and W. Uhring, presented at 2013 Conference on Design and Architectures for Signal and Image Processing (DASIP) shows the 3D imager with clusters of pixels sharing a readout and an ADC:
Why the memory depth can be increased with digital memory?
ReplyDeleteWhy the frame rate is slowed down by x100 in digital configuration?
Approach looks very straightforward without real innovations.
