    摘要: An interactive input system comprises at least one imaging device having a field of view looking into a region of interest, a bezel at least partially surrounding the region of interest and having a surface in the field of view of the at least one imaging device, a first radiation source emitting radiation into the region of interact that is generally matched to the characteristics of the bezel so that the radiation emitted by the first radiation source is reflected by the bezel surface generally towards the at least one imaging device and a second radiation source emitting radiation into the region of interest that is generally unmatched to the characteristics of the bezel so that the radiation emitted by the second radiation source is not reflected by the bezel surface.

    摘要: A method of operating an interactive input system comprises capturing images of a region of interest at a first frame rate; processing a first pixel subset of images captured at the first frame rate to detect the presence of an object; and if an object is detected, capturing images of the region of interest at a second frame rate.
