Samsung's new Vizion 33D ToF sensor can track objects at 120 fps at up to 5m distance

05 November 2020
It's a time of flight sensor that benefits from the ISOCELL technology. It can be used for video bokeh on the rear camera or face ID on the front.

      Anonymous, 05 Nov 2020LOL, those 2 and 5MP depth sensors are not ToF. They are... moreThat's where things are complicated, because if you use them to either compute depth from 3D stereoscopy or by AI, you can get pretty accurate depth map, which effectively turn them into real depth camera (not real depth sensor though), in fact you could even use an ultra shallow depth of field and vary the focus to scan using phase detection to gather a quite good depth map too.
      And some of the 2Mp are ToF, but there are no available informations on what type of ToF they are, so we don't know if this is the sensor resolution, the depth map resolution or anything else, my comment was simplified, just to say that, a 0.3Mp depth map is stupid low as the main use of depth data on smartphone is for computational photography (even if AR start to kick in) and for this you need a wayyyyy higher depth resolution, so even 2Mp depth camera that gather depth from an AI would be more useful than a true depth sensor who only have 0.3Mp.

        They are just old regular sensors (used between 2010-2015) that have photo/video capabilities disabled by Software.

              -MicroLED and MiniLED is becoming more of a thing.

              You are over exaggerating. Either that or you are left in the past.

                Lasuto, 05 Nov 2020You know nothing Jon Snow. Depth Maps resolution is not wha... moreActually I do, I know that while an image resolution will be the same as the sensor resolution (at least the RAW), the depth resolution is not based on the number of pixels the sensor have, but rather on the number of points in the point cloud the sensor is able to give, so a 30k dot projector like the Apple Face ID have a 0.03Mp depth resolution for example despite the sensor being obviously higher resolution.

                BUT, the thing is, there is a type of Flash LiDAR that don't use a dot array for Structured Light or ToF, but rather use a single wide beam and use a per pixel detection, and while I am not sure how they handle the phase shift with that, one sure thing is that, with this method, the sensor resolution actually is the depth resolution.

                Now for AR content and many basic depth measurement, a low resolution depth map is enough, but for photography, you actually want the highest possible resolution, ideally being the same angular resolution (post binning) of your main sensor which often is 12Mp.
                As computational photography would require to spend processing power that would be useful for other thing upscalling the resolution, and in the process creating unavoidable artifacts and errors, causing things like hairs to be blurred when doing an artificial bokeh effect for portrait shots and making impossible more advanced effects, while a 12Mp depth map, even noisy, would allow for amazing things.
                That's why, regardless if this is the sensor or the depth map resolution, those tiny numbers, 0.3Mp, 0.5Mp, 2Mp, 5Mp or 7Mp are stupid low.
                But the higher the sensor resolution, the higher the depth map precision though, independently of the depth resolution.

                So, no, I am not mixing up sensor (image) and depth map resolution, despite the simplification I did in my comment (comparing depth map resolution and sensor resolution) sound like it, because when a single beam Flash LiDAR is used, the sensor to depth resolution become close to 1, and honestly it is a pain in the b... to know which phone have which type, so I assume that some actually use single beam Flash LiDAR.

                              Sadly there are persons who think they know better and don't even facts check who say I am wrong while I always fact check when I go technical, this doesn't help teaching the proper thing...

                              I love going in depth as I love both learning and teaching, and indeed for some it is hard to recognize the good engineering behind a product from a brand they don't like, so rather than learning how it work, they just stay convinced it is bad.

                                    Poma, 05 Nov 2020is this tech similar to that of LiDAR sensor?TL;DR :Yes and no, it is all about naming, and the issue is that the naming is a mess, marketing used ToF and LiDAR as buzzwords and totally ignoring any naming conventions.
                                    But ToF basically how you use light (can also be other things) and LiDAR is what you do with this light, so by definition, many LiDAR use ToF, it is more like "Car" and "Vehicle" than "Car" and "Motorcycle".

                                    Long answer :
                                    ToF = Time of Flight is simply using the speed of anything having a constant velocity to measure distance, it can be light, it can be sound, it can be mmWaves (radar).
                                    There is a difference between ToF and 3D ToF though, while ToF is measuring range using time, which is typically done through pulsing a laser and measuring the time it take to comeback, and who can use a single IR detector or a camera sensor, it is used on the typical Laser Rangefinder and Laser Autofocus, but the 3D ToF is what is used to get depth.
                                    There are a wide variety of technique, and you can either use the time light travel from your source to your sensor, but also what we call phase detection, and here you simply either emit a lot of lasers (an array of laser diodes or the same who have gone through a diffraction grating) or a single wide beam of either a LED or a widen laser beam) to detect many points and have a big depth resolution (which is not the same as the sensor resolution).

                                    LiDAR = "Light Detection And Ranging" or "Laser imaging, Detection, And Ranging" is basically using light, most often in the form of lasers but not limited to, to built a depth map.
                                    There are a lot of different type of LiDAR, most actually use ToF, but some use other techniques like "Structured Light" which is what Apple Face ID use.
                                    Though Structured Light is typically used for 3D Scanners which are their own specific type and while they have a better precision, 3D Scanners aren't LiDAR because of their use and Structured Light aren't good at longer range, which is why LiDAR almost always use ToF which have lesser precision but way higher range, but some specialized LiDAR do use Structured Light.

                                    So ToF and LiDAR aren't the same thing, but they often come together.
                                    But the truth is, there is a huge difference between what the proper term is and how we call all those, there are a lot of interpretations, but the proper naming convention should only include as LiDAR what really detect object AND measure their range, which is what is typically done on LiDARs mounted on cars, but if we accept that the "Detection" part is more about what you'll measure through Light (meaning physical objects but not the air for exemple), then anything that "use light and that at the end of the process you get a distance of a specific object" or "anything that use light and make you able to construct a depth map using distance data" is a LiDAR, meaning that any 3D ToF is then a LiDAR, so is Apple Face ID.

                                        When you know that the difference between a regular 3D ToF sensor and any other camera sensor is almost non-existant, this is totally stupid low resolution, the same stupidity that choosing a 2Mp sensor for Macro, Portrait or whatever else is.
