Abstract:
Provided is an image pickup apparatus comprising: a light control mirror element (ace CME) having a function of splitting an incident light flux (LF) into a first LF from reflection and a second LF from transmission and a function of switching between a semi-transmissive/semi-reflective state (s-t/s-rS) and a totally reflective state (TRS); a LF splitting unit causes first and second LFs to be emitted from first and second exit surfaces (ES), respectively; an electrochromic element (EE) switches between a state of transmitting light having a first wavelength range (WR) out of first LF (first state) and a state of transmitting light having a second WR out of first LF (second state); and a control device conducts switching control between a first mode in which LCME is in s-t/s-rS and EE is in first state and a second mode in which LCME is in TRS and EE is in second state.
