Patent ID: 6922285

Claim:
An optical system for forming parallactic images in a time-series manner, comprising: a pair of front optical components, each of said pair of front optical components having a negative optical power; an optical for superposing respective optical axes of said pair of front optical components on each other; a rear optical component disposed such that the superposed optical axes coincide with an optical axis of said rear optical component, said rear optical component having a lens unit arranged to move along the optical axis for variation of magnification; a pair of shutter members arranged to alternately change amounts of transmission of light fluxes respectively entering said pair of front optical components from an object; and a pair of deflection members, each of said pair of deflection members disposed between said pair of front optical components and said optical member, arranged to deflect light fluxes coming from said pair of front optical components and to guide the deflected light fluxes to said optical member, wherein the size of each of said pair of deflection members corresponds to an angular extension of the light fluxes coming from said pair of front optical components when the lens unit is at a wide angle end.
