Description

Camera devices and optical instruments

[0001] This embodiment relates to a camera device and an optical device.

[0002] A camera device is a device that captures a subject as a photo or video, and is installed in optical devices such as smartphones, drones, vehicles, etc.

[0003] The camera device is equipped with an autofocus function that automatically adjusts the focus based on the distance to the subject. In addition, it features image stabilization to compensate for user hand shake.

[0004] At this time, a ball that guides the movement of the movable part may be placed between the movable part and the fixed part.

[0005] However, in conventional camera devices, there is a problem where the ball strikes the molded fixed and movable parts, causing dents to form on them.

[0006] (Patent Document 1) KR 10-2015-0118005 A

[0007] The present embodiment aims to provide a camera device in which the phenomenon of indentation of an injection molded product caused by a ball is prevented through an insert member.

[0008] In addition, we aim to provide a camera device with a minimized size in the direction of the optical axis.

In the direction of the optical axis, the coupling portion of the third insert member may be positioned higher than the second insert member and lower than the ball contact portion of the first insert member.

The ball (550) includes a plurality of balls, and each of the plurality of balls can guide both the x-axis direction movement and the y-axis direction movement of the OIS carrier (210). With such a structure, a size reduction effect in the optical axis direction can be expected compared to a comparative example in which the x-axis direction guide ball and the y-axis direction guide ball are used separately. More specifically, in the comparative example, the x-axis direction guide ball and the y-axis direction guide ball are arranged in two layers, increasing the size in the optical axis direction, but in this embodiment, the ball (550) is arranged in one layer, so the size in the optical axis direction can be minimized.

[0183] The operation of the camera device according to the present embodiment will be described below with reference to the drawings.

[0184] FIG. 20 is a drawing for explaining AF driving of a camera device according to the present embodiment.

[0185] The AF carrier (310) can be positioned at a location spaced apart from the top plate (121) and the base (110) of the cover (120) respectively, in an initial position where no current is applied to the AF coil (420).

[0186] When current is applied to the AF coil (420), an electromagnetic field is formed around the AF coil (420), and the AF coil (420) can move in the optical axis direction (OA) by electromagnetic interaction with the driving magnet (410). At this time, the AF carrier (310) and the lens can move together with the AF coil (420). That is, when current is applied to the AF coil (420), the AF coil (420), the AF carrier (310), and the lens (see A in FIG. 20) can move in the optical axis direction (see B in FIG. 20).

[0187] When a forward current is applied to the AF coil (420), the AF coil (420) can move upward in the direction of the optical axis due to the electromagnetic interaction between the AF coil (420) and the driving magnet (410). At this time, the AF carrier (310) can move upward in the direction of the optical axis together with the AF coil (420). Furthermore, the lens can move upward in the direction of the optical axis together with the AF carrier (310). Accordingly, the distance between the lens and the image sensor (60) changes, and the focus of the image formed on the image sensor (60) through the lens can be adjusted.

[0188] When a reverse current is applied to the AF coil (420), the AF coil (420) can move downward in the direction of the optical axis due to the electromagnetic interaction between the AF coil (420) and the driving magnet (410). At this time, the AF carrier (310) can move downward in the direction of the optical axis together with the AF coil (420). Furthermore, the lens can move downward in the direction of the optical axis together with the AF carrier (310). Accordingly, the distance between the lens and the image sensor (60) changes, and the focus of the image formed on the image sensor (60) through the lens can be adjusted.

[0189] Meanwhile, the AF sensor (450) can detect the amount of movement or position of the lens in the direction of the optical axis by detecting the strength of the magnetic field of the sensing magnet (440) moving together with the AF carrier (310). Autofocus feedback control can be performed using the amount of movement or position of the lens in the direction of the optical axis detected by the AF sensor (450).

[0190] FIG. 21 is a diagram for explaining the OIS driving of a camera device according to the present embodiment.

[0191] The OIS carrier (210) can be placed in an initial position without current being applied to the OIS-x coil (431) and the OIS-y coil (432). In the initial position, the OIS carrier (210) can be spaced apart from the side plate (122) of the cover (120) in the x-axis direction and the y-axis direction.

[0192] When current is applied to the OIS-x coil (431), the driving magnet (410) can move in the x-axis direction perpendicular to the optical axis due to the electromagnetic interaction between the OIS-x coil (431) and the driving magnet (410). At this time, the OIS carrier (210) can move in the x-axis direction together with the driving magnet (410). Furthermore, the AF carrier (310) and the lens can move in the x-axis direction together with the OIS carrier (210).

[0193] More specifically, when a forward current is applied to the OIS-x coil (431), the driving magnet (410), OIS carrier (210), AF carrier (310), and lens (see A in FIG. 21) can move in one direction along the x-axis. Additionally, when a reverse current is applied to the OIS-x coil (431), the driving magnet (410), OIS carrier (210), AF carrier (310), and lens can move in the other direction along the x-axis.

[0194] When current is applied to the OIS-y coil (432), the driving magnet (410) can move in the y-axis direction perpendicular to the optical axis due to the electromagnetic interaction between the OIS-y coil (432) and the driving magnet (410) (see B in FIG. 21). At this time, the OIS carrier (210) can move in the y-axis direction together with the driving magnet (410). Furthermore, the AF carrier (310) and the lens can move in the y-axis direction together with the OIS carrier (210).

[0195] More specifically, when a forward current is applied to the OIS-y coil (432), the driving magnet (410), OIS carrier (210), AF carrier (310), and lens can move in one direction along the y-axis. Additionally, when a reverse current is applied to the OIS-y coil (432), the driving magnet (410), OIS carrier (210), AF carrier (310), and lens can move in the other direction along the y-axis.

[0196] Meanwhile, the OIS-x sensor can detect the magnetic field strength of the driving magnet (410) to detect the amount of movement or position of the driving magnet (410). Using the amount of movement or position detected by the OIS-x sensor, hand shake correction feedback control in the x-axis direction can be performed. The OIS-y sensor can detect the magnetic field strength of the driving magnet (410) to detect the amount of movement or position of the driving magnet (410). Using the amount of movement or position detected by the OIS-y sensor, hand shake correction feedback control in the y-axis direction can be performed.
