The dedicated macro lens allows users to get up close to the objects while capturing the images and the dedicated 2MP depth sensor allows real-time depth detection for a better bokeh effect in the images.
Samsung Galaxy S21 5G / Galaxy S21 Ultra 5G - Set Up Face Recognition. Facial recognition is utilized to unlock the device. For optimal performance, ensure you are indoors or away from direct sunlight.
Part 2: Which one is more Accuracy? Being accurate is a considerable issue with face recognition technology if you are using a Samsung device. On the other hand, iPhone X shows accuracy than Samsung since it analyzes the whole face instead of iris. Apple has no such accuracy issue for it takes your face to recognize.

The technology that enables Face ID is some of the most advanced hardware and software that we've ever created. The TrueDepth camera captures accurate face data by projecting and analyzing thousands of invisible dots to create a depth map of your face and also captures an infrared image of your face.
The multiple inputs from the camera provide a high dynamic range, sharp details and also help in making an intricate depth map. The optics are backed by ZEISS which ensures the clearest of images and minimum lens-related distortion. The multiple cameras provide up to 10 times more light than a normal sensor.
Stereo depth cameras have two sensors, spaced a small distance apart. A stereo camera takes the two images from these two sensors and compares them. Objects closer to us will appear to move significantly from eye to eye (or sensor to sensor), where an object in the far distance would appear to move very little.
Bokeh is defined as “the effect of a soft out-of-focus background that you get when shooting a subject, using a fast lens, at the widest aperture, such as f/2.8 or wider.†Simply put, bokeh is the pleasing or aesthetic quality of out-of-focus blur in a photograph.
It uses two camera lenses, spaced slightly apart, to let the phone compare two images and piece together the depth of objects in stereo, similar to how human eyes tell how far away something is. By determining distortions in the pattern of dots, the phone can map depth far more accurately than the passive system.
Also known as a depth sensor, a ToF (time-of-flight) camera is a type of smartphone sensor that analyzes a scene and can determine the distance and depth of the objects in that environment. The phone can then take that data and use it to create a 3D map of the scene.
As phone technology advances, so does mobile camera technology. As a result, many cameras now feature multiple rear cameras — dual, triple, or quad — so you can get a pro-level photography experience with your smartphone. With the addition of another camera, you can broaden your photo-taking abilities.
Primarily, a mobile with four camera setup allows you to click better photos with a higher field of depth. It can also offer a bokeh effect similar to DSLRs, faster focusing, capturing more detail, and monochrome photos.

3D Depth camera: The S10 5G has two cameras that none of the standard models offer. Both of them use the same time-of-flight technology to capture a realistic 3D depth map of what they're pointed at.
How Are LiDAR and ToF Different? The functional difference between LiDAR and other forms of ToF is that LiDAR uses pulsed lasers to build a point cloud, which is then used to construct a 3D map or image. ToF applications create "depth maps" based on light detection, usually through a standard RGB camera.
So, ToF was out and Laser AF was in for the Galaxy S21 Ultra launch as well, which will carry over to next year's S22 series. According to insiders, Samsung thought about bringing the ToF sensor back after Apple included one on the iPhone 12 Pro and Pro Max.
The LiDAR scanner allows fast and accurate focus even in near darkness. These improvements set it apart from the already great iPhone 12 Pro. Samsung has added extra capabilities to its Galaxy S21 Ultra cameras as well.
Laser-based time-of-flight cameras are part of a broader class of scannerless LIDAR, in which the entire scene is captured with each laser pulse, as opposed to point-by-point with a laser beam such as in scanning LIDAR systems.
Samsung, often considered the leader in Android phones, offers a wide range of smartphones. Then, Samsung introduced a rear-facing “lidar†in its Galaxy S10 5G, S20+, S20, and its ISOCELL Vizion 33D models, used for camera focus and virtual-reality applications.
The Ultra Wide Camera is part of the pro-grade camera system on Galaxy S20, S20+, S20 Ultra, and Z Flip. With a 123 degree field of vision, it expands your view in a significant way, seeing almost as much as your eyes can — much wider than the Wide-angle Camera does.
Apple says the new LiDAR sensor can measure an object up to five meters (16 feet) away. In contrast, a ToF sensor on existing smartphones can only detect objects at a maximum distance of around two metres.
Lidar stands for light detection and ranging, and has been around for a while. It uses lasers to ping off objects and return to the source of the laser, measuring distance by timing the travel, or flight, of the light pulse. Trying some of the LiDAR-enabled AR apps I can find for the 2020 iPad Pro, to show meshing.
Why Samsung removed ToF camera in Galaxy Note 20 Ultra.
3D time of flight (ToF) is a type of scanner-less LIDAR (light detection and ranging) that uses high power optical pulses in durations of nanoseconds to capture depth information (typically over short distances) from a scene of interest.
