Abstract

A mobile device includes a camera module and a magnetism generating part that is different from the camera module. The camera module includes: a movable portion that corrects camera shake; a magnetism detecting element that detects a position of the movable portion. when the camera module is in a photographing state, the magnetism generating part is arranged at a position distant from the magnetism detecting element by at least the distance of D mm or more, where

$D=\sqrt{\mathrm{magnetic}\mathrm{force}\mathrm{of}\mathrm{the}\mathrm{magnetism}\mathrm{generating}\mathrm{part}\left[\mathrm{gauss}\right]}.$

Claims

1. A mobile device comprising:

a camera module; and

a magnetism generating part that is different from the camera module;

wherein the camera module includes;

a movable portion that corrects camera shake; and

a magnetism detecting element that detects a position of the movable portion, and

when the camera module is in a photographing state, the magnetism generating part is arranged at a position distant from the magnetism detecting element by at least the distance D mm or more, and

2. The mobile device according to claim 1,

wherein the magnetic force of the magnetism generating part is 100 gauss and the magnetism generating part is arranged at a position distant from the magnetism detecting element by the distance of 10 mm or more.

3. The mobile device according to claim 1,

wherein the magnetism generating part is a speaker.

4. The mobile device according to claim 3, further comprising:

a liquid crystal display that displays information which is arranged between the camera module and the speaker.

5. The mobile device according to claim 1, further comprising:

a plurality of housings; and

a magnetism sensor,

wherein the plurality of housings are superimposed on each other when the mobile device is not used,

the plurality of housings are not superimposed on each other when the mobile device is used,

the magnetism generating part is a magnet, and

the magnetism sensor detects a state in which the plurality of housings are superimposed by detecting magnetism generated by the magnet.

6. The mobile device according to claim 1,

wherein the mobile device is a portable cellular phone.

7. A mobile device comprising:

a plurality of camera modules; and

a speaker,

wherein a first camera module in the plurality of camera modules is a camera module not having a movable portion,

a second camera module in the plurality of camera modules is a camera module including (i) a movable portion that corrects camera shake and also (ii) a magnetism detecting element that detects a position of the movable portion of the second camera module,

the speaker is arranged at a position adjacent to the first camera module, and

the second camera module is arranged at a position at which the magnetism detecting element attached to the second camera module is distant from the speaker by the distance at least 10 mm or more.

8. The mobile device according to claim 7,

wherein the second camera module further includes a liquid crystal display that displays information which is arranged between the second camera module and the speaker.

9. The mobile device according to claim 7,

wherein the mobile device is a portable cellular phone.
