Claim of US Patent No. 10,433,398

1. A system comprising:a dual-mode display screen comprising a plurality of display members, in a first mode of operation of the dual-mode display screen the plurality of display members transmitting visible light and forming an image on the dual-mode display screen, and in a second mode of operation of the dual-mode display screen the plurality of display members transmitting infrared (IR) light into an environment surrounding the dual-mode display screen;
a dual-mode camera comprising a plurality of imaging members, in a first mode of operation of the dual-mode camera the plurality of imaging members receiving visible light and forming an image of visible light, and in a second mode of operation of the dual-mode camera the plurality of imaging members receiving IR light and forming an image of IR light;
a controller coupled to the dual-mode display screen and the dual-mode camera synchronizing the dual-mode display screen and the dual-mode camera by sending a first instruction to the dual-mode display screen to transmit IR light, and sending a second instruction to the dual-mode camera to receive IR light; and
a filtering member comprising a plurality of spectral filters, a first spectral filter in the plurality of spectral filters allowing green light and IR light to pass through the first spectral filter, a second spectral filter in the plurality of spectral filters allowing red light and IR light to pass through the second spectral filter, and a third spectral filter in the plurality of spectral filters allowing blue light and IR light to pass through the third spectral filter at the same time.
