It is further monitored whether the display area lies off a link area set for a link source image. When even part of the display area lies off the link area, a link in the link area is determined as invalid (Y in S38), and display is returned to the link source image (S40). When either is not the case, display is continued while the display area is moved in the active image according to viewpoint movement (N in S36, N in S38, S42). When the user gives an instruction to terminate, display is finished (Y in S46).

Title: Rotation angle detector
Inventor: MATSUMOTO KOICHIRO
IPC: G01D5/14
Filed: 2010-10-06
Abstract: PROBLEM TO BE SOLVED: To provide a rotation angle detector having a simple configuration and strong robustness.SOLUTION: In a rotation angle detector 2 that detects the rotation angle of a rotating detection target, a first wall 41 and a second wall 42 of a frame-shaped yoke 40, which includes the rotation axis z of a detection target therein, are parallel to each other. This results in uniform distribution of magnetic flux vector in the direction orthogonal to the first wall 41. Therefore, even when a Hall element 5 is out of position, the density of the detected magnetic flux hardly changes and the rotation angle detector 2 obtains robustness. Further, the distance Y2 from the Hall element 5 to an inner wall 42a of the second wall 42 is shorter than the distance Y1 from the Hall element 5 to an inner wall 41a of the first wall 41. The length X2 of the inner wall 42a is longer than the length X1 of the inner wall 41a. Accordingly, the uniform region of the magnetic flux vector is can be expanded on the second wall 42 side close to the Hall element 5, resulting in enhancement of robustness.
