Abstract:
1. An instructed position setting device for setting an instructed position during three-dimensional display, the device comprising: an instructed position detecting unit for detecting an instructed position instructed on a display surface of a display unit where an instruction image is displayed, the instruction image including at least one instruction area for receiving a predetermined instruction, and the instruction image being displayable two-dimensionally and three-dimensionally, wherein the instructed position detecting unit detects the instructed position by receiving an input within at least one instruction area included in the instruction image by a user; and a control range setting unit for setting on the display unit a control range corresponding to the instruction area of the instruction image displayed on the display unit, the instruction area being detected when receiving the input thereto by the user, such that the control range is changed between when the instruction image is two-dimensionally displayed and when the instruction image is three-dimensionally displayed, wherein when the instruction image is three-dimensionally displayed, the control range setting unit obtains information of a tentative instructed position by receiving an instruction directed to the instruction area, calculates an amount of shift in the horizontal direction on the display unit of the tentative instructed position when the instruction image is three-dimensionally displayed relative to a position of the instruction area when the instruction image is two-dimensionally displayed, and changes a position of the control range based on the amount of shift in the horizontal direction to make the position of the control range coincide with a visually recognized position of the instruction area through stereoscopic viewing when the instruction image is three-dimensionally displayed.
