Abstract

An information processing apparatus includes a body, and a display detachably provided on the body. The display includes an attitude notifying device configured to generate and notify, to the body, attitude data of the display based on a change in attitude of the display detected in a state in which the display is detached from the body. The body includes a rotation processing device configured to perform a rotation process on image data displayed on the display and output rotated image data, based on the attitude data of the display, and a communication device configured to transmit the rotated image data to the display.

Claims

1. An information processing apparatus comprising:

a body; and

a display detachably provided on the body,

wherein the display comprises a first processor configured to perform a process including

generating attitude data of the display based on a change in attitude of the display detected in a state in which the display is detached from the body, to notify the attitude data to the body, and

wherein the body comprises a second processor configured to perform a process including

performing a rotation process on image data displayed on the display and output rotated image data, based on the attitude data of the display, and

first transmitting the rotated image data to the display.

2. The information processing apparatus as claimed in claim 1, wherein the first processor of the display performs the process further including

second transmitting the attitude data of the display to the body, using a band different from a band in which the image data are transmitted and received between the body and the display.

3. The information processing apparatus as claimed in claim 1, wherein the generating generates the attitude data of the display based on the change in the attitude of the display, after a predetermined time elapses from a time when the attitude of the display no longer changes.

4. The information processing apparatus as claimed in claim 3, wherein the first processor of the display performs the process further including

detecting docking of the display to the body,

wherein, in a case in which the detecting detects the docking, the generating generates the attitude data of the display based on the change in the attitude of the display, without waiting for the predetermined time to lapse from the time when the attitude of the display no longer changes, to notify the attitude data to the body.

5. The information processing apparatus as claimed in claim 2, wherein the generating notifies the attitude data to the body by controlling an amount of data of the attitude data according to a state of radio waves in wireless communication between the body and the display.

6. The information processing apparatus as claimed in claim 1, wherein the first processor of the display performs the process further including

controlling at least one of turning off a backlight of a screen of the display, turning on the backlight of the screen, and a luminance of the backlight of the screen, when displaying the rotated image data on the screen.

7. The information processing apparatus as claimed in claim 1, wherein the display further comprises:

a sensor group configured to detect the change in the attitude of the display.

8. The information processing apparatus as claimed in claim 7,

wherein the sensor group includes an acceleration sensor that detects accelerations in three mutually perpendicular axes of the display, and a magnetic field sensor that detects an orientation of a magnetic field, and

wherein the first processor of the display performs the process further including

computing an inclination of the display based on the accelerations detected by the acceleration sensor, and

computes a direction in which the display is rotated based on the orientation detected by the magnetic field sensor.

9. The information processing apparatus as claimed in claim 1,

wherein, in a state in which the display is detached from the body, the first transmitting transmits the image data or the rotated image data by wireless communication to the display using a first band, and

wherein the first processor of the display performs the process further including

in the state in which the display is detached from the body, second transmitting the attitude data of the display to the body by wireless communication using a second band different from the first band.

10. A display detachable with respect to a body of an information processing apparatus, comprising:

a sensor group configured to detect attitude of the display;

a screen; and

a processor configured to perform a process including

generating attitude data of the display based on a change in the attitude of the display detected by the sensor group in a state in which the display is detached from the body,

notifying the attitude data to the body, and

receiving rotated image data of the image data from the body, rotated in the body based on the attitude data, and

displaying the rotated image data, received by the receiving, on the screen,

wherein the notifying and the receiving perform wireless communication in a state in which the display is detached from the body.

11. The display as claimed in claim 10, wherein the notifying transmits the attitude data of the display to the body using a band different from a band in which the image data or the rotated image data are received from the body by the receiving.

12. The display as claimed in claim 10, wherein the generating generates the attitude data of the display based on the change in the attitude of the display, after a predetermined time elapses from a time when the attitude of the display detected by the sensor group no longer changes.

13. The display as claimed in claim 12, wherein the processor performs the process further including

detecting docking of the display to the body, and

wherein the generating generates the attitude data of the display based on the change in the attitude of the display, without waiting for the predetermined time to lapse from the time when the attitude of the display detected by the sensor group no longer changes, in a case in which the detecting detects the docking.

14. The display as claimed in claim 11,

wherein the processor performs the process further including

monitoring a state of radio waves in wireless communication between the display and the body, and

wherein the notifying notifies the attitude data to the body by controlling an amount of data of the attitude data according to the state of radio waves monitored by the monitoring.

15. The display as claimed in claim 10, further comprising:

a backlight of the screen,

wherein the processor performs the process further including

controlling at least one of turning off the backlight, turning on the backlight, and a luminance of the backlight, when the displaying displays the rotated image data on the screen.
