Patent Description:
As various portable terminals are widely spread and commonly used, and the wireless Internet services have been commercialized, the demands of consumer related to portable terminals have been diversified and various kinds of additional devices have been installed in portable terminals.

Among them, there is a camera device for photographing a subject as a photograph or a moving picture. Meanwhile, a camera device in recent years has been applied with a hand shake correction function that prevents an image from being shaken due to hand shake of a photographer.

However, the conventional OIS structure of the camera module tilt method is a two-axis hand shake correction method for yawing/pitching that rotates around the X-axis/Y-axis, and there is a disadvantage in that hand shake caused by rolling that rotates around the Z-axis cannot be corrected.

In addition, there is a problem in that the amount of deflection of the posture difference due to gravity occurs in the conventional camera device.

<CIT> relates to an imaging device equipped with a hand shake compensation function. The imaging device comprises a coil in the outside of the bobbin in which a lens unit is mounted.

The present embodiment is to provide a camera device capable of <NUM>-axis hand shake correction for yawing, pitching, and rolling, with an OIS structure of a module tilt method.

In addition, it is to provide a camera device that does not cause deflection of a camera module according to a posture difference.

In addition, it is to provide a camera device in which the stress concentration generated in the substrate is dispersed due to the contact support structure.

The first magnet may comprise a first-first magnet disposed on the first lateral surface of the camera module and a first-second magnet disposed on the second lateral surface of the camera module, and the first coil may comprise a first-first coil facing the first-first magnet and a first-second coil facing the first-second magnet.

The second coil may comprise a second-first coil facing the first-first magnet and disposed on one side of the first-first coil, a second-second coil facing the first-first magnet and disposed on the other side of the first-first coil, a second-third coil facing the first-second magnet and disposed on one side of the first-second coil, and a second-fourth coil facing the first-second magnets and disposed on the other side of the first-second coil.

The second magnet comprises a second-first magnet disposed on the third lateral surface of the camera module and a second-second magnet disposed on the fourth lateral surface of the camera module, wherein the third coil may comprise a third-first coil facing the second-first magnet and a third-second coil facing the second-second magnet.

The camera device may further comprise a holder having at least a portion thereof being disposed inside the housing and coupled to the camera module, an upper elastic member having a portion thereof being coupled to the holder, and a wire connecting the upper elastic member and the base.

The camera device further comprises a first substrate disposed on an outer surface of the housing, wherein the coil may be coupled to an inner surface of the first substrate.

The camera module comprises a second substrate on which the image sensor is disposed and a flexible third substrate coupled to the second substrate, wherein the third substrate may comprise an inner portion comprising a terminal connected to a terminal disposed on a lower surface of the second substrate, an outer portion fixed to the base and comprising a terminal, and a connection portion that connects the inner portion and the outer portion and is bent at least in portion.

The invention further refers to an optical apparatus as defined in claim <NUM>.

Through the present embodiment, enhanced hand shake correction (OIS) function can be provided by performing <NUM>-axis hand shake correction of yawing, pitching, and rolling with a module tilt method.

In addition, since deflection of the camera module according to the posture difference does not occur, the control for hand shake correction becomes simpler and more precise hand shake correction can be performed in all postures.

The coil <NUM> may comprise a second coil <NUM>. The second coil <NUM> may face the first magnet <NUM>. The second coil <NUM> may be electrically separated from the first coil <NUM>.

As illustrated in <FIG>, the second coil <NUM> can rotate the camera module <NUM> to one side about the y-axis through interaction with the magnet <NUM> (refer to a in <FIG>).

For example, the electromagnetic interaction force a1 between the second-first coil <NUM>-<NUM> and the first-first magnet <NUM>-<NUM> and the electromagnetic interaction force a1 between the second-third coil <NUM>-<NUM> and the first-second magnet <NUM>-<NUM> is directing upward, and the electromagnetic interaction force a2 between the second-second coil <NUM>-<NUM> and the first-first magnet <NUM>-<NUM> and the electromagnetic interaction force a2 between the second-fourth coil <NUM>-<NUM> and the first-second magnet <NUM>-<NUM> may be directing downwards. Although it has been described that currents in different directions are applied to the second-first coil <NUM>-<NUM> and the second-second coil <NUM>-<NUM>, in a modified embodiment, the winding directions of the coils are disposed opposite to each other and currents in the same direction may be applied.

As illustrated in <FIG>, the second coil <NUM> can rotate the camera module <NUM> to the other side about the y-axis through interaction with the magnet <NUM> (refer to d in <FIG>). In more detail, when a reverse current is applied to the second-first coil <NUM>-<NUM>, a downward electromagnetic interaction force d1 is generated between the second-first coil <NUM>-<NUM> and the first-first magnet <NUM>-<NUM>; when a reverse current is applied to the second-third coil <NUM>-<NUM>, a downward electromagnetic interaction force d1 is generated between the second-third coil <NUM>-<NUM> and the first-second magnet <NUM>-<NUM>; when a forward current is applied to the second-second coil <NUM>-<NUM>, an upward electromagnetic interaction force d2 is generated between the second-second coil <NUM>-<NUM> and the first-first magnet <NUM>-<NUM>; and when a forward current is applied to the second-fourth coil <NUM>-<NUM>, an upward electromagnetic interaction force d2 is generated between the second-fourth coil <NUM>-<NUM> and the first-second magnet <NUM>-<NUM>, so that the camera module <NUM> can rotate d to the other side about the y-axis.

The second coil <NUM> may comprise a plurality of coils. The second coil <NUM> may comprise second-first to second-fourth coils <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM>. The second-first coil <NUM>-<NUM> may face the first-first magnet <NUM>-<NUM>. The second-first coil <NUM>-<NUM> may be disposed on one side of the first-first coil <NUM>-<NUM>. The second-second coil <NUM>-<NUM> may face the first-first magnet <NUM>-<NUM>. The second-second coil <NUM>-<NUM> may be disposed on the other side of the first-first coil <NUM>-<NUM>. The second-third coil <NUM>-<NUM> may face the first-second magnet <NUM>-<NUM>. The second-third coil <NUM>-<NUM> may be disposed on one side of the first-second coil <NUM>-<NUM>. The second-fourth coil <NUM>-<NUM> may face the first-second magnet <NUM>-<NUM>. The second-fourth coil <NUM>-<NUM> may be disposed on the other side of the first-second coil <NUM>-<NUM>.

The second-first to second-fourth coils <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> may be electrically connected. Through this, the second-first to second-fourth coils <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> may be integrally controlled. However, as another example, all of the second-first to second-fourth coils <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> may be electrically separated. In this case, the second-first to second-fourth coils <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> may be individually controlled. That is, the direction and amount of current applied to each of the second-first to second-fourth coils <NUM>-<NUM>, <NUM>-<NUM>, <NUM>-<NUM>, and <NUM>-<NUM> may be individually controlled. As another example, the second-first coil <NUM>-<NUM> and the second-third coil <NUM>-<NUM> are electrically connected, and the second-second coil <NUM>-<NUM> and the second-fourth coil <NUM>-<NUM> are electrically connected, and the second-first coil <NUM>-<NUM> and the second-second coil <NUM>-<NUM> may be electrically separated.

The coil <NUM> may comprise a third coil <NUM>. The third coil <NUM> may face the second magnet <NUM>. The third coil <NUM> may be electrically separated from the first coil <NUM> and the second coil <NUM>.

As illustrated in <FIG>, the third coil <NUM> can rotate the camera module <NUM> to one side about the optical axis through interaction with the magnet <NUM> (see c of <FIG>). In more detail, when a forward current is applied to the third-first coil <NUM>-<NUM>, an electromagnetic interaction force c1 is generated in the first direction between the third-first coil <NUM>-<NUM> and the second-first magnet <NUM>-<NUM>, and when a forward current is applied to the third-second coil <NUM>-<NUM>, an electromagnetic interaction force c2 is generated in the second direction between the third-second coil <NUM>-<NUM> and the second-second magnet <NUM>-<NUM>, so that the camera module <NUM> can rotate c to one side about the z-axis. At this time, the first direction and the second direction are tangential directions of a circle centered on the optical axis, respectively, and may be symmetrical with respect to the optical axis. Although it has been described that a forward current is applied to each of the third-first coil <NUM>-<NUM> and the third-second coil <NUM>-<NUM>, currents may be applied to the third-first coil <NUM>-<NUM> and the <NUM>-<NUM> coil <NUM>-<NUM> in different directions. At this time, a necessary electromagnetic interaction force can be induced through the disposed direction of the second-first magnet <NUM>-<NUM> and the second-second magnet <NUM>-<NUM> or the winding direction of the third-first coil <NUM>-<NUM> and the third-second coil <NUM>-<NUM>.

As illustrated in <FIG>, the third coil <NUM> can rotate the camera module <NUM> to the other side about the optical axis through interaction with the magnet <NUM> (refer to f in <FIG>). In more detail, when a reverse current is applied to the third-first coil <NUM>-<NUM>, an electromagnetic interaction force f1 is generated in the third direction between the third-first coil <NUM>-<NUM> and the second-first magnet <NUM>-<NUM>, and when a reverse current is applied to the third-second coil <NUM>-<NUM>, an electromagnetic interaction force f2 is generated in the fourth direction between the third-second coil <NUM>-<NUM> and the second-second magnet <NUM>-<NUM>, so that the camera module <NUM> can rotate f to the other side about the z-axis.
