Abstract:
1. A system to adjust depth of an image of a three-dimensional object, the system comprising: a two-dimensional display device configured to display an image of a three-dimensional object stored in a three-dimensional coordinate system; an input interface configured to receive, from an input device that is separate from the two-dimensional display device, operation information to adjust a z-coordinate value of the object in the three-dimensional coordinate system; an operation information determination unit configured to determine whether a trajectory of two-dimensional coordinate values in a first plane of the operation information is in accordance with a particular rule based on whether the trajectory of the two-dimensional coordinate values in the first plane of the operation information is included between two circles having a common center and mutually-different radii; and an update unit configured to adjust the z-coordinate value of the object in the three-dimensional coordinate system and not to adjust xy-coordinate values of the object in the three-dimensional coordinate system, the z-coordinate value being adjusted in a second plane orthogonal to the first plane based on the operation information in response to the trajectory of the two-dimensional coordinate values in the first plane of the operation information being in accordance with the particular rule, wherein an amount of adjustment of the z-coordinate value is proportional to a number of approximately-circular rotations formed by the trajectory of the two-dimensional coordinate values in the first plane of the operation information.
