[0218] Below, the auto focus (AF) operation of the lens driving device according to the present embodiment is described.
[0219] Fig. 27 is a drawing for explaining auto focus operation of a camera device according to the present embodiment.
[0220] The moving part may be positioned at a position spaced apart from both the upper plate (121) of the cover (120) and the base (110) in the initial position where no current is applied to the AF coil (420). At this time, the moving part may include a carrier (340). Furthermore, the moving part may include a carrier (340), a lens, and an AF magnet (410).
[0221] When current is applied to the AF coil (420), the moving part (see A in FIG. 27) can move upward or downward along the optical axis (see B in FIG. 27).
[0222] When a positive current is applied to the AF coil (420), the AF magnet (410) can move upward in the optical axis direction due to the electromagnetic interaction between the AF coil (420) and the AF magnet (410).

[0230] When current is applied to the OIS-x coil (512), the OIS-x magnet (511) can move in the x-axis direction perpendicular to the optical axis due to the electromagnetic interaction between the OIS-x coil (512) and the OIS-x magnet (511). At this time, the housing (310) can move in the x-axis direction together with the OIS-x magnet (511). Furthermore, the carrier (340) and the lens can move in the x-axis direction together with the housing (310). More specifically, when a positive current is applied to the OIS-x coil (512), the OIS-x magnet (511), the housing (310), the carrier (340), and the lens can move in one direction on the x-axis. Additionally, when reverse current is applied to the OIS-x coil (512), the OIS-x magnet (511), housing (310), carrier (340), and lens can move in the other direction along the x-axis.
[0231] When current is applied to the OIS-y coil (522), the moving part (see A in Fig. 28) can move in the y-axis direction (see C in Fig. 28).
[0232] When current is applied to the OIS-y coil (522), the OIS-y magnet (521) can move in the y-axis direction perpendicular to the optical axis due to the electromagnetic interaction between the OIS-y coil (522) and the OIS-y magnet (521).

Additionally, when a reverse current is applied to the OIS-y coil (522), the OIS-y magnet (521), frame (330), housing (310), carrier (340), and lens can move in the other direction along the y-axis.
[0233] Meanwhile, the OIS-x sensor (513) can detect the strength of the magnetic field of the OIS-x magnet (511) to detect the amount of movement or position of the OIS-x magnet (511). The amount of movement or position detected by the OIS-x sensor (513) can be used for x-axis direction shake correction feedback control. The OIS-y sensor (523) can detect the strength of the magnetic field of the OIS-y magnet (521) to detect the amount of movement or position of the OIS-y magnet (521).

[0236] When current is applied to the OIS-Yo coil (532), the moving part can be tilted in the yaw direction (see B in Fig. 29).
[0237] When current is applied to the OIS-yaw coil (532), the OIS-yaw magnet (531) can be tilted in the yaw direction due to the electromagnetic interaction between the OIS-yaw coil (532) and the OIS-yaw magnet (531). That is, it can be tilted around the first axis. In other words, it can be rotated within a limited range around the first axis (see A of FIG. 29). At this time, the image sensor (220) and the lens together with the OIS-yaw magnet (531) can be tilted in the yaw direction. More specifically, when a positive current is applied to the OIS-yaw coil (532), the OIS-yaw magnet (531), the image sensor (220), and the lens can move in one direction on the yaw. Additionally, when a reverse current is applied to the OIS-Yo coil (532), the OIS-Yo magnet (531), the image sensor (220), and the lens can move in the opposite direction of the yoke.
[0238] Meanwhile, the OIS-yaw sensor (533) can detect the strength of the magnetic field of the OIS-yaw magnet (531) to detect the amount of movement or position of the OIS-yaw magnet (531). The amount of movement or position detected by the OIS-yaw sensor (533) can be used for yaw direction shake compensation feedback control.

Furthermore, the moving part can include a sensor base (320), a frame (330), a housing (310), a carrier (340), an image sensor (220), and a lens.
[0241] When current is applied to the OIS-pitch coil (542), the moving part can be tilted in the pitch direction (see D in Fig. 30).
[0242] When current is applied to the OIS-pitch coil (542), the OIS-pitch magnet (541) can be tilted in the pitch direction by the electromagnetic interaction between the OIS-pitch coil (542) and the OIS-pitch magnet (541). That is, it can be tilted around the second axis (see C of FIG. 30). In other words, it can be rotated within a limited range around the second axis. At this time, the image sensor (220) and the lens together with the OIS-pitch magnet (541) can be tilted in the pitch direction. More specifically, when a positive current is applied to the OIS-pitch coil (542), the OIS-pitch magnet (541), the image sensor (220), and the lens can move in one direction on the pitch. Additionally, when reverse current is applied to the OIS-pitch coil (542), the OIS-pitch magnet (541), the image sensor (220), and the lens can move in the other direction on the pitch.
[0243] Meanwhile, the OIS-pitch sensor (543) can detect the strength of the magnetic field of the OIS-pitch magnet (541) to detect the amount of movement or position of the OIS-pitch magnet (541). The amount of movement or position detected by the OIS-pitch sensor (543) can be used for pitch direction shake correction feedback control.
[0244] In this embodiment, the x-axis shift drive (see A in FIG. 10) and the y-axis shift drive (see B in FIG. 10) are such that the image sensor (220) is fixed and only the lens can move. However, the yaw tilting (see C in FIG. 10) and the pitch tilting (see D in FIG. 10) may be a module tilt method in which the lens and the image sensor (220) move together.
