Methods and apparatus for illuminating scene areas to facilitate depth determination are described. A sequence of frames is displayed, e.g., projected, onto a scene area to illuminate the area for image capture. The sequence of frames includes a patterned frame followed by a concealing frame. The patterned frame and concealing frame are each displayed for no more than 1/60 of a second. The concealing frame maybe and sometimes does display a complementary pattern to the preceding patterned frame. When viewed sequentially by a human viewer the human sees a non-distracting uniformly illuminated scene area as a result of the effect of the concealing frame. One or more cameras are used to capture images of the illuminated area during a time in which the pattern is displayed and the scene area is effectively painted with a pattern that can facilitate depth determination based on one or more captured images.
A method of capturing images of an area illuminated with an illumination sequence of frames including a first illumination frame corresponding to a first illumination frame period having a first light pattern followed by a first concealing frame having a second light pattern, the first illumination frame period having a first frame duration, the first concealing frame having a second frame duration, the second light pattern concealing the first light pattern when the illuminated area is observed over a duration corresponding to the combined period having a combined duration equal to the sum of the first and second frame durations, the method comprising:
An system for use in an area illuminated with an illumination sequence of frames including a first illumination frame corresponding to a first illumination frame period and having a first light pattern followed by a first concealing frame having a second light pattern, the first illumination frame period having a first frame duration, the first concealing frame having a second frame duration, the second light pattern concealing the first light pattern when the illuminated area is observed over a duration corresponding to the combined period having a combined duration equal to the sum of the first and second frame durations, comprising:
A non-transitory machine readable medium including processor executable instructions which when executed by a processor control the capture and use of one or more images in an area illuminated with an illumination sequence of frames including a first illumination frame corresponding to a first illumination frame period having a first light pattern followed by a first concealing frame having a second light pattern, the first illumination frame period having a first frame duration, the first concealing frame having a second frame duration, the second light pattern concealing the first light pattern when the illuminated area is observed over a duration corresponding to the combined period having a combined duration equal to the sum of the first and second frame durations, the processor, as part of controlling the capture and use of one or more image performing the steps of:
