Description

Camera Apparatus {Camera Apparatus}

Disclosed is a structure of a camera device, particularly a shake compensation technique for compensating for shake of a dual camera.

Recently, in addition to the auto focus function, camera modules are increasingly adopting a shake compensation function in order to prevent deterioration of the resolution of the captured image due to shaking such as external vibration or user's hand shake. For example, an optical image stabilizer (OIS) may be used as a device for performing a shake correction function. In general, the optical OIS detects shake and changes the position of an optical lens or an image sensor, so that even if there is camera shake, an image of a subject formed on an image sensor can be corrected without shaking.

By the way, the optical OIS includes a driving mechanism to change the position of the optical lens or image sensor. For this reason, when a camera is built into a smartphone or a drone, the optical OIS requires more mounting space and power. Therefore, the optical OIS of the camera needs to be configured to be able to implement miniaturization and weight reduction and to reduce power consumption in order to be easily adopted in smartphones or drones.

Meanwhile, as a camera module for use in various electronic devices, a dual camera module in which two single camera modules are arranged side by side has been recently studied. This dual camera module is a camera module for synthesizing two or more images taken by each single camera module to generate a composite image with high resolution or high resolution and high MTF (modulation transfer function). However, when the auto-focus function and the shake correction function are employed in such a dual camera, it becomes more difficult to reduce the size/light weight of the camera module and save power.

An object of the present invention is to provide a camera device capable of reducing the size and weight of a dual camera, reducing power consumption, and preventing image distortion during shake correction.

A camera device according to the present invention includes a camera housing, a carrier assembly for accommodating two imaging assemblies, a first guide for coupling the carrier assembly to the camera housing so as to be movable in a first direction perpendicular to an optical axis of the imaging assembly, and the carrier assembly for the camera. a first driving unit for moving the housing in a first direction; and a control unit for controlling the first driving unit to move the carrier assembly in a first direction offsetting the motion according to a motion sensing signal of the camera housing.

According to the present invention, since the dual cameras share the OIS function, it may be advantageous for miniaturization and weight reduction of the camera device, and power consumption may be reduced. In addition, the camera according to the present invention can prevent image distortion during shake correction.

An object of the present invention is to provide a camera device capable of reducing the size and weight of a dual camera, reducing power consumption, and preventing image distortion during shake correction.

In general, in the case of a dual camera, since the angle of view (tele) of one single camera module is smaller than that of the other single camera module, the image contains more pixels for the same subject area, so the resolution or The resolution or MTF may be high. That is, a higher quality composite image (C) can be generated when shooting with a single camera module. Therefore, since the optical characteristics of the two single camera modules, that is, the angle of view are different, it is necessary to independently perform an auto focusing (AF) function.

However, even if the optical characteristics of the two single camera modules of the dual camera are different, there is no need to independently perform image stabilization. Therefore, in the camera device proposed in the present invention, the carrier assembly accommodating the dual camera is operated to structurally compensate for the shake of the dual camera at a time, so that it can be advantageous for miniaturization and weight reduction, and power consumption can be reduced.

However, the camera device proposed by the present invention proposes three embodiments according to the shake compensation direction and the number of carriers.

Referring to FIG. 1 , the camera housing 100 is configured to accommodate and protect the components therein. Although not shown in the drawing, a cover having a hole formed in the center is mounted on the module base in a state in which the components are combined on the base. can be

Here, in the module base, a signal processing circuit electrically connected to the component is a module. For example, a flexible printed circuit board (FPCB) may be implemented in a polygonal or circular shape. In addition, the hole formed in the cover is to allow light to be incident through the lenses fixed to each of the two imaging assemblies. In addition, the cover may block electromagnetic interference (EMI). That is, the cover may block external electromagnetic waves from entering the inside. Furthermore, it is possible to block electromagnetic waves generated inside the cover from being emitted to the outside.

The carrier assembly 200 houses two imaging assemblies 201 , 202 . Although not shown in the drawings, each of the imaging assemblies 201 and 202 may include a lens having a different angle of view, and each of the imaging assemblies 201 and 202 may each independently auto-focus by a driving unit that elevates and lowers a lens barrel to which the lens is fixed by the control unit. Focusing, AF) function may be performed. The Auto Focus (AF) function automatically focuses on the subject by adjusting the distance from the image sensor by moving the lens in the optical axis direction according to the distance of the subject so that a clear image of the subject can be obtained on the image sensor. defined as a function.

Here, the 'optical axis' may be understood as a line connecting the center of the lens configured in the imaging assemblies 201 and 202 and the center of the image sensor, and thus the 'optical axis direction' coincides with the optical axis, is parallel to the optical axis, or is substantially It can be understood as a parallel direction. In addition, as an example, assuming a coordinate system constituting the x-axis, y-axis, and z-axis, if the z-axis is an optical axis, the direction in which only (x, y) is expressed as well as the x-axis and y-axis may be a direction perpendicular to the optical axis .

The first guide 310 couples the carrier assembly 200 to the camera housing 100 so as to be movable in a first direction perpendicular to the optical axis of the imaging assemblies 201 and 202 . According to the first modified example, the first guide 310 may be implemented as a hinge or a ball that rotatably couples one outer surface of the carrier assembly 200 and one inner surface of the camera housing 100 opposite to the other. One outer surface and one inner surface may be parallel to the first direction.

Accordingly, the carrier assembly 200 may be tilted in the y-axis direction about the x-axis with respect to the hinge or the ball.

The first driving unit 410 moves the carrier assembly 200 to be tilted in the first direction with respect to the camera housing 100 .

According to the first modification, the first driving unit 410 includes a permanent magnet 410b fixed to the other outer surface of the carrier assembly 200 to provide a driving force to the carrier assembly 200, and the camera housing.

That is, in the case of an open-loop control method in which only the input is considered and no output is considered when controlling the output, the controller drives the coil 410a by a pre-designed sensitivity when current is applied. However, in reality, there may be a case in which the driving is not performed as much as the sensitivity, and thus a driving distance error may occur.

On the other hand, in the case of a closed-loop control method that considers the input and the feedback output when controlling the output, the control unit returns to the target position based on the feedback signal from the sensor that detects the position information of the actuator. If not reached, correct the driving error.

According to an aspect, the control unit may be implemented in a form embedded in the camera device, for example, electrically connected to the components on a flexible printed circuit board (FPCB) on the module base of the camera housing 100 . It may be implemented in the form of a signal processing circuit (not shown).

According to another aspect, the controller may be provided in an electronic device on which the camera device is mounted. Here, the electronic device includes a mobile phone, a smart phone, a laptop computer, a digital broadcasting terminal, personal digital assistants (PDA), a portable multimedia player (PMP), a navigation system, a slate PC, and a tablet PC. (tablet PC), ultrabook (ultrabook), wearable device (wearable device, for example, watch-type terminal (smartwatch), glass-type terminal (smart glass), HMD (head mounted display) may be applied to any one. However, the present invention is not limited thereto, and any device for photographing an image is possible.

According to one aspect, the gyro sensor may be provided in the camera device to sense the motion of the camera housing 100. According to another aspect, the gyro sensor may be provided in an electronic device in which the camera device is mounted.

In addition, the control unit individually controls the direction, strength, amplitude, etc. of the current supplied to the coil 410a of the first driving unit 410, by the force of the magnetic field applied to the coil 410a and the permanent magnet 410b. The operating speed or movement amount of the carrier assembly 200 may be adjusted. According to the first modification, the controller applies a current to the coil 410a so that the first driving unit 410 tilts the carrier assembly 200 in the first direction, that is, in the y-direction.

The tilting operation for the shake compensation (OIS) according to the first modification is as follows.

When a user's hand shake or device vibration is sensed by a gyro sensor (not shown) of an electronic device such as a smartphone or a drone on which the camera device according to the present invention is mounted, the control unit of the electronic device (not shown) controls the first A shake correction signal is transmitted to the driving unit 410 .

According to the shake correction signal, a current flows through the coil 410a of the first driving unit 410 to generate electromagnetic force. The strength of the attractive or repulsive force acting on the permanent magnet 410b is determined by the direction of the current flowing in each coil 410a to determine the tilting direction of the carrier assembly 200, and the density of the electromagnetic force line according to the strength of the current The strength of the attractive or repulsive force acting on the permanent magnet 410b of the carrier assembly 200 is determined to determine the degree of tilting (correction amount).
