[0167] Hereinafter, the auto focus (AF) operation of the camera device according to the present embodiment will be described with reference to the drawings.

[0168] Fig. 19 is a drawing for explaining auto focus operation of a camera device according to the present embodiment.

[0169] When current is applied to the AF coil (320), the AF magnet (310) can move in the optical axis direction due to the electromagnetic interaction between the AF coil (320) and the AF magnet (310) (see B of FIG. 19). At this time, the lens and the AF carrier (210) can move together with the AF magnet (310) (see A of FIG. 19). Through this, the distance between the lens and the image sensor (60) can be changed, so that the focus of the image formed on the image sensor (60) through the lens can be adjusted.

[0170] When a positive current is applied to the AF coil (320), the AF magnet (310) can move upward in the optical axis direction due to the electromagnetic interaction between the AF coil (320) and the AF magnet (310). At this time, the lens and the AF carrier (210) can move upward in the optical axis direction together with the AF magnet (310).

[0171] When a reverse current is applied to the AF coil (320), the AF magnet (310) can move downward in the optical axis direction due to the electromagnetic interaction between the AF coil (320) and the AF magnet (310). At this time, the lens and the AF carrier (210) can move downward in the optical axis direction together with the AF magnet (310).

[0172] Meanwhile, during the movement process of the AF magnet (310), the AF sensor (330) can detect the strength of the magnetic field of the AF magnet (310) to detect the amount of movement or position of the AF magnet (310). The amount of movement or position of the AF magnet (310) detected by the AF sensor (330) can be used for auto focus feedback control. In the present embodiment, the real-time position of the lens is detected through the AF sensor (330) to adjust the amount and direction of the current applied to the AF coil (320), so that more precise auto focus operation can be performed.

[0173]

[0174] Below, the optical image stabilization (OIS) operation of the camera device according to the present embodiment is described with reference to the drawings.

[0175] Fig. 20 is a drawing for explaining the shake correction operation of the camera device according to the present embodiment.

[0176] When current is applied to the OIS-x coil (350), the OIS-x magnet (340) can move in the x-axis direction due to the electromagnetic interaction between the OIS-x coil (350) and the OIS-x magnet (340) (see A of FIG. 20). At this time, the x-axis direction may be a direction perpendicular to the optical axis and the y-axis. The lens and the AF carrier (210) and the OIS-x carrier (220) can move in the x-axis direction together with the OIS-x magnet (340). Through this, the misalignment in the x-axis direction between the lens and the image sensor (60) caused by an external force applied to the camera device, for example, a user's hand shake, can be offset.

[0177] When current is applied to the OIS-y coil (380), the OIS-y magnet (370) can move in the y-axis direction due to the electromagnetic interaction between the OIS-y coil (380) and the OIS-y magnet (370) (see B of FIG. 20). At this time, the y-axis direction may be a direction perpendicular to the optical axis and the x-axis. The lens, the AF carrier (210), the OIS-x carrier (220), and the OIS-y carrier (230) can move in the y-axis direction together with the OIS-y magnet (370). Through this, the misalignment in the y-axis direction between the lens and the image sensor (60) caused by an external force applied to the camera device, for example, a user's hand shake, can be offset.
