A display control device (20, 30) comprising: a determining unit configured to identify a real object (40, 40A-C) in a real space image captured by an imaging device and to determine an orientation of said real object (40, 40A-C) with respect to an imaging optical axis of the imaging device; and a control unit configured to: select between first and second orientations for adding an image of a virtual object (50A-C) onto the real space image based on the determined real object orientation, the first orientation for adding the image of the virtual object (50A-C) in a plane parallel or co-planar with a first plane of the real object (40, 40A-C) and the second orientation, different from the first orientation, for adding the image of the virtual object (50A-C) onto a plane oriented at an angle with respect to the first plane of the real object (40, 40A-C); wherein selecting between first and second orientations further comprises: selecting the first orientation when a rotation angle of the first plane of the real object (40, 40A-C) around an axis intersecting with the imaging optical axis of the real space image with reference to the front facing state of the real object (40, 40A-C) is less than or equal to a threshold value; and selecting the second orientation when the rotation angle of the first plane of the real object (40, 40A-C) around the axis intersecting with the imaging optical axis of the real space image with reference to the front facing state of the real object is greater than the threshold value; wherein the control unit is further configured to output the real space image including the image of the virtual object (50A-C) aligned according to the selected orientation, for display on an associated display device. a determining unit configured to identify a real object (40, 40A-C) in a real space image captured by an imaging device and to determine an orientation of said real object (40, 40A-C) with respect to an imaging optical axis of the imaging device;
