Abstract

When an electronic book 1 momentarily moves by Δy in the direction of the arrow A because of a vibration, an image display 7 (an LCD module 15) is changed downward by Δy so that when the user is viewing an image, the user'"'"'s line of sight is substantially fixed like when there is hardly any vibration on the electronic book 1. By performing such an operation in each of the X axis and Y axis directions, the relative position of the display image in the direction of the X axis with respect to the user'"'"'s line of sight because of a vibration in the X axis direction (the direction of an arrow D) of the image display 7 (the LCD module 15) is made fixed, and the relative position of the display image in the direction of the Y axis with respect to the user'"'"'s line of sight because of a vibration in the direction of the Y axis (the direction of an arrow C) of the image display 7 (the LCD module 15) is made fixed.

Claims

1. An electronic apparatus comprising:

a display that displays an image;

a first detector that detects a vibration provided to the image display apparatus; and

a display controller that moves a display position of the image displayed on'"'"'the display in a direction opposite to a direction of a motion in the vibration of the image display apparatus detected by the first detector.

2. An electronic apparatus according to claim 1 further comprising:

a second detector that detects a motion of a predetermined part of a body of a user of the image display apparatus,

wherein the display controller moves the display position of the image displayed on the display by use of detection results of the first and second detectors.

3. An electronic apparatus according to claim 1,

wherein the first detector is an acceleration sensor that detects an acceleration of, of the motion of the image display apparatus which motion constitutes the vibration, a motion in a direction substantially parallel to a display screen of the display.

4. An electronic apparatus comprising:

a display that displays an image;

a driver that drives the display in a direction substantially parallel to a display screen of the display;

a first detector that detects a vibration provided to the image display apparatus; and

a driving controller that causes the driver to drive the display in a direction opposite to a direction of a motion in the vibration of the image display apparatus detected by the first detector.

5. An electronic apparatus according to claim 4,

wherein the driver comprises:

a first and a second base member;

a first holder that holds the second base member so as to be relatively movable in a first direction with respect to the first base member;

a first actuator that drives the second base member in the first direction with respect to the first base member;

a second holder that holds the display so as to be relatively movable in a second direction, different from the first direction, with respect to the second base member; and

a second actuator that drives the display in the second direction with respect to the second base member.

6. An electronic apparatus according to claim 4 further comprising:

a second detector that detects a motion of a predetermined part of a body of a user of the image display apparatus,

wherein the driving controller causes the driver to drive the display by use of detection results of the first and second detectors.

7. An electronic apparatus according to claim 4,

wherein the first detector is an acceleration sensor that detects an acceleration of, of the motion of the image display apparatus which motion constitutes the vibration, a motion in a direction substantially parallel to a display screen of the display.

8. An image display method for displaying an image on a display, the method comprising:

detecting a vibration of the display; and

moving a display position of the image displayed on the display in a direction opposite to a motion in the detected vibration of the display.

9. An image display method according to claim 8 further comprising:

detecting a motion of a predetermined part of a body of a user of the display,

wherein the display position of the image displayed on the display is moved by use of detection results of the vibration of the display and the motion of the predetermined part.

10. An image display method for displaying an image on a display, the method comprising:

detecting a vibration of the display; and

driving the display in a direction opposite to a motion in the detected vibration of the display.

11. An image display method according to claim 10 further comprising:

detecting a motion of a predetermined part of a body of a user of the display,

wherein the display is moved by use of detection results of the vibration of the display and the motion of the predetermined part.
