Abstract: The present invention relates to a portable terminal in which the orientation of the displayed subject is the same as the actual orientation of the subject. The reference attitude when taking a picture is shown in FIG. 5, with the lid 12 being rotated substantially about 90 degrees about the X-axis with respect to the main body, and a perpendicular of the display 32 is in the same orientation as the optical axis of the CCD 41. In this attitude, the image captured by the CCD 41 is displayed as it is in the display 32. On the other hand, when the angle detector 51 detects that the lid 12 is rotated by a further 90 degrees with respect to the main body 11 from the attitude of FIG. 5 and the lid 12 and the main body 11 are opened by about 180 degrees, the image captured by the CCD 41 is rotated by 90 degrees, and the rotated image is displayed in the display 32. The present invention can be applied to portable type terminals such as mobile phones having a two axially rotatable structure, PDA, personal computers.

Abstract: In order to nullify the adverse effect of an external magnetic field on a static magnetic field generated in an MRI system, small-size coils are used to generate a compensation magnetic field. Thus, the component of the static magnetic field to be applied to a magnetic sensor is canceled. The magnetic sensor can therefore detect the external magnetic field highly precisely. A correction current proportional to the external magnetic field detected highly precisely is fed to BO correction coils. Eventually, the external magnetic field that adversely affects the static magnetic field is canceled.
