Abstract: Provided is a transmissive display apparatus capable of naturally combining a projection image on a real space scene. A beam splitter splits a light incident from a real space scene into first and second portions. An image sensor generates a real space image according to the second portion of the incident light. A light modulator passes at least a part of the first portion of the incident light according to a masking image. A control and projection image generation unit selects a target object and generates the masking image based on a target object area to cause a light modulator to block a foreground of the real space scene and pass a background of the real space scene. A projection unit generates a projection image light corresponding to the projection image combines the projection image light with a part of the first portion of the incident light.
