Abstract:
1. A display control apparatus for controlling display of a radiograph to be displayed on a head mounted display, comprising: a generation unit adapted to generate an X-ray moving image by detecting X-rays that irradiate a subject; a setting unit adapted to, when displaying the X-ray moving image superimposed on a main image to be displayed on a display unit of the head mounted display, set a display ratio of the main image and the X-ray moving image in accordance with a display condition; an image composition unit adapted to generate a composite image by superimposing the X-ray moving image on the main image on the basis of the ratio set by said setting unit; a display processing unit adapted to display the composite image on the display unit of the head mounted display; and a viewpoint detection unit adapted to detect information about a viewpoint of a user who is wearing the head mounted display, wherein when said viewpoint detection unit detects that the viewpoint of the user exists in a display area of the X-ray moving image, said setting unit switches the ratio to display the X-ray moving image with a priority over the main image, and said image composition unit generates the composite image by superimposing the X-ray moving image on the main image on the basis of the ratio switched by said setting unit.
