Why are there so many unnecessarily aggressive comments? With regards to iToF - iToF can surely achieve longer depth by binning similarly to dToF. A key advantage dToF has over iToF is histogramming with which multipath/multi-camera can be overcome - but also here methods exist for iToF. So simply saying that iToF can't reach long depth sensing is oversimplified at best.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-47735651832688095902021-06-01T08:19:20.431+03:002021-06-01T08:19:20.431+03:00You seem to be highly confused between a SPAD dept...You seem to be highly confused between a SPAD depth sensor and a SPAD high DR sensor. Pls review them once. Coming to resolution query - Longer depths are more important than resolutions for depth sensing. And iToF, having higher resolution sensors, cannot do that.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-12567442477333311222021-06-01T03:34:26.421+03:002021-06-01T03:34:26.421+03:00The question that I care the most is how many &quo...The question that I care the most is how many "effective" pixels it can provide after grouping a number of pixels for the necessary coincidence detection with the existence of ambient light (e.g. sunlight). iPad Pro uses Sony's 200*150 pixel SPAD for its LiDAR sensor while only produces 24*24 effective pixels (the seemingly richer point cloud is a combination of the interpolation from the NIR sensor images and the helps from hand movement "scanning"). That's 6*8 native SPAD pixel for one effective pixel! If this continuous to be true, the 1MP SPAD is merely a ~150*150 sensor.

He was a Canon employee on educational leave at EPFL, and fully leveraged Canon resources to make realize this chip. While I served on his PhD committee, I don't recall where the chip was fabricated but I believe the cost and arrangements were done taken care of by Canon. Perhaps it was fabricated on Japanese soil but definitely NOT at EPFL. Of course Kazu was well-mentored at EPFL by his advisor Edoardo Charbon and it was certainly joint work of Canon and EPFL. It would likely not exist without EPFL but the work was done by a Canon employee. It would have been better if Canon had acknowledged that fruitful collaboration with EPFL, but as we know from several large companies (particularly in Japan), they become very self-centric in these press releases.
