“…In light of these benefits, research in single-chip RGBD is an emerging area. Our results compare well to the previous papers on single-sensor RGBD imaging, where in [15] spatial resolution is sacrificed and in [18] the acquisition is not real time.…”

“…In terms of color, the ToF camera in [18] time multiplexes red green and blue LEDs, but the technique is for static scenes. Recently, Kim et al [15] report the first real-time color RGBD sensor, by redesigning the silicon sensor to multiplex both color and depth pixels (this decreases the depth pixel count by a factor of 4). Time of flight technology is of interest to the broader community beyond range imaging; see recent work in ultrafast imaging [24,13,11,33,12], BRDF acquisition [19], multi-path imaging [13], [3], [2], and looking around corners [32].…”

Several computer vision algorithms require a sequence of photographs taken in different illumination conditions, which has spurred development in the area of illumination multiplexing. Various techniques for optimizing the multiplexing process already exist, but are geared toward regular or high speed cameras. Such cameras are fast, but code on the order of milliseconds. In this paper we propose a fusion of two popular contexts, time of flight range cameras and illumination multiplexing. Time of flight cameras are a low cost, consumer-oriented technology capable of acquiring range maps at 30 frames per second. Such cameras have a natural connection to conventional illumination multiplexing strategies as both paradigms rely on the capture of multiple shots and synchronized illumination. While previous work on illumination multiplexing has exploited coding at millisecond intervals, we repurpose sensors that are ordinarily used in time of flight imaging to demultiplex via nanosecond coding strategies.

“…The proposed approach has the advantage of a better MTF compared to [KYO12], where RGB pixels are separated from an additional range pixel. The approach presented in [KKK12], however, is quite similar to this one. Here 8 pixels, that may work in colour mode, can be binned to yield range measurements by the continuously modulated principle (CW).…”

“…Recently, a sensor family has been proposed to achieve a compact pixel capable of 2D/3D imaging simultaneously, whereas one 3D pixel is obtained from 16 2D pixels using a so-called hierarchical binning strategy [33]. The sensor thus achieves 1920x1080 pixel resolution in 2D and 480x270 in 3D; it uses a pinned photodiode structure in standard 0.11µm CIS process operating at 20MHz with a centimetric depth resolution at a range of 4.5m.…”

Abstract-Time-of-flight imaging is a subset of imaging science interested in the detection of the time-of-flight of certain waves, usually light, to reconstruct the position of objects in a 3D scene. Optical time-of-flight imagers have existed for decades, but it is only with the introduction of solid-state sensors with fast (global) shutters, that they have become compact and prone to mass-production. In these sensors, light propagation can be frozen in time and space and its time-of-flight can be evaluated on the pixel-by-pixel basis to accurately reconstruct 3D scenes and volumes.Applications include gaming, gesture recognition, and virtual keyboards for short-range cameras, security, 3D video monitoring, and robotic operation for medium-range cameras, safety and pedestrian avoidance for long-range cameras, and LIDAR telemetry and landscape monitoring for ultra-long-range cameras. Also based on similar concepts are non-vision applications, such as time-of-flight positron emission tomography, fluorescence lifetime imaging microscopy, and time-resolved optical coherent tomography, to name a few.
