INFORMATION DISPLAY CONTROL DEVICE, INFORMATION DISPLAY DEVICE, AND INFORMATION DISPLAY CONTROL METHOD

PROBLEM TO BE SOLVED: To improve operability by using three-dimensional position information of an instruction object to devise screen display.SOLUTION: A control unit converts an intra-input surface position, which is a position right below an instruction object along a normal of an input surface of an input device, in the input surface to an intra-display surface position of a display device on the basis of three-dimensional information of the instruction object (two-dimensional position conversion processing). On the basis of the three-dimensional position information, the control unit adjusts visibilities of a first object (for example, an icon 40) pointed by a prompt displayed in the intra-display surface position and a second object being another object (for example, a map image) so that the smaller a distance z0 from the input surface to the instruction object along the normal of the input surface is the larger the difference in visibility between the first and second objects is (visibility adjustment processing).
