Abstract

An information processing apparatus including a main body, a member including a projection device, the member moveably attached to the main body, a detector that detects an orientation of the moveable member with respect to the main body, and a processor that controls the projection device based on an output of the detector.

Claims

a main body;

a member including a projection device, the member attached to the main body and movable in at least first and second axial directions with respect to the main body; and

circuitry configured to detect an orientation of the movable member with respect to the main body;

detect whether the main body faces a first direction or a second direction;

detect whether the information processing apparatus is stationary; and

control the projection device to be turned on when it is detected indicates that the information processing apparatus faces the first direction, the information processing apparatus is stationary, a first surface of the member faces a direction substantially similar to the first direction and an angular orientation of the member around an axis perpendicular to the first direction with respect to the main body is within +/−

45 degrees.

2. The information processing apparatus of claim 1, wherein the information processing apparatus is one of a digital video camera, a personal computer, a home game machine, a portable phone, a portable music playback device, a portable image processing device or a portable game machine.

3. The information processing apparatus of claim 1, wherein the circuitry includes a gravity sensor configured to detect a direction that the main body faces.

4. The information processing apparatus of claim 1, wherein the member includes a touch-panel interface on the first surface of the member.

5. The information processing apparatus of claim 4, wherein the projection device is located on a side surface of the member that is substantially perpendicular to the first surface, on the first surface of the member or a second surface of the member that opposes the first surface.

6. The information processing apparatus of claim 1, wherein the circuitry is configured to detect an angular orientation of the member with respect to the main body.

7. The information processing apparatus of claim 1, wherein the circuitry is configured to detect a first angle of the member with respect to the main body in the first axial direction, and a second angle of the member with respect to the main body in the second axial direction.

8. The information processing apparatus of claim 1, wherein the circuitry is configured to detect whether the main body faces the first direction in which an optical unit of the information processing apparatus faces upward or whether the main body faces the second direction in which the optical unit of the information processing apparatus faces downward.

9. The information processing apparatus of claim 8, wherein the member includes a touch-panel interface on the first surface of the member.

10. The information processing apparatus of claim 9, wherein the circuitry is configured to detect a first angle of the member with respect to the main body in the first axial direction, and a second angle of the member with respect to the main body in the second axial direction.

11. The information processing apparatus of claim 1, wherein the circuitry is configured to control the projection device to be turned off when it is detected that the information processing apparatus does not face the first direction, the information processing apparatus is not stationary, the first surface of the member does not face a direction substantially similar to the first direction, or an angular orientation of the member around an axis perpendicular to the first direction with respect to the main body is not within +/−
