Fig. 5From: Phase disambiguation using spatio-temporally modulated illumination in depth sensingUpper and lower bound of the ROI. Orange lines represent the candidate depths of spatial modulation; blue lines represent the candidate depths of temporal modulation. The width of the line shows the resolution. a If the depth is near than dmin, several candidate depths from spatial modulation (orange lines) exist within the resolution of temporal modulation (blue band). b On the other hand, if the depth is longer than dmax, several candidate depths from temporal modulation (blue lines) exist within the spatial resolution (orange band)Back to article page
