The present invention relates to a shift image stabilization device using an image sensor, and more particularly, is mounted on a mobile communication terminal having a small digital camera and an optical device. Shift image stabilization device using image sensor to obtain a clear image by moving the drive frame equipped with the image sensor in synchronization with the micro vibrations according to the shaking of the recording device so that the image is not disturbed even in the minute vibration of the human body It is about.

Recently, with the development of compact and lightweight digital cameras, camera devices can be mounted in mobile communication terminals, and mobile communication terminals equipped with optical lenses and camera devices are becoming more common. As the camera lens assembly mounted on the mobile communication terminal further increases its fluidity, image disturbance due to minute vibration or hand shaking generated from the human body is intensified. There is an increasing need to correct vibrations. In addition, high-definition cameras have appeared due to the development of optical technology, but the effect of mounting a high-resolution camera is halved due to the image disturbance caused by the vibration of vibration, thereby increasing the necessity of a hand shake correction device.

Currently, there are two main techniques for compensating for camera shake. One of the image stabilization techniques is digital image stabilization (DIS) and electronic image stabilization (EIS), which are electronic image stabilization techniques, which detect hand shake from the result of captured images and correct data stored in the camera element or memory. The camera device accepts the distracted image as it is, and adjusts the position and color using an electronic method or a program to produce a distorted image. Such electronic image stabilization technology has the advantage of low cost and low structural constraints, which are easy to employ because there is no need for a separate mechanical and physical configuration, but there is a disadvantage that a separate memory or a high performance camera element is required because it is corrected by a program. In addition, since the time required to correct the already disturbed image is longer, the shooting speed may be slower, and the correction rate may be lowered because there is a limitation in removing afterimages through a program.

Another type of image stabilization technique is an optical image stabilization apparatus (OIS). The optical image stabilizer is a method of correcting an image of a subject formed on a camera element without shaking by detecting a hand shake and changing the position of an optical lens or a camera element. The optical image stabilization device has a separate correction device installed to increase the manufacturing cost and the difficulty of providing an installation space, but the correction rate is 90% or more because it can remove the afterimage by imaging the image without disturbance on the camera element If the conditions are maintained and use the same performance camera element, there is an advantage that can shoot relatively clear image compared to the device using the electronic image stabilization device. Therefore, the optical image stabilization device is used more often than the electronic image stabilization device in the imaging device requiring a high resolution.

On the other hand, a technique for moving and correcting an optical lens can be adopted in a digital camera having a sufficient space to include a driving unit for driving the optical lens, but there are limitations in employing a small digital camera or a mobile communication terminal with a limited space. Therefore, researches on techniques for compensating for hand shake by moving camera elements have been actively conducted.

Japanese Patent Laid-Open No. 10-39350 discloses an optical image stabilization device. The disclosed image stabilization device uses a frictional force by placing an X-axis piezoelectric element and a Y-axis piezoelectric element on the outer side of the optical lens, and providing a separate support portion for supporting them, by contacting the optical lens with the driving shaft of the piezoelectric element according to the degree of distorting. It is a structure which moves by a predetermined distance. As described above, in order to install a driving device such as a piezoelectric element on the outer side of the optical lens, the outer diameter of the optical lens must be sufficiently secured, so that it is difficult to install in a mobile communication terminal in which the length and the outer diameter of the camera lens assembly are extremely limited. . In addition, there is a limit to downsizing the driving device because a considerable driving force must be generated in order to drive an optical lens having a certain weight, and since a considerable power consumption is required, mounting on a portable photographing device using a rechargeable battery is limited. . In addition, the difficulty in designing a small drive device and the increase in manufacturing cost due to the increase in the number of parts are obstacles to securing the price competitiveness of a photographing device having an image stabilizer. In addition, in the case of a contact drive device using a frictional force with a drive shaft, such as a piezoelectric element, not only there is a difficulty in managing the tolerance of the contact surface, but there is a problem in that reliability occurs due to a malfunction when the contact surface is worn. In addition, a driving circuit for generating and applying a specific voltage waveform is required to drive a driving device such as a piezoelectric element, which increases manufacturing cost and restricts the simplification of the photographing apparatus.

Therefore, it is mounted on a mobile communication terminal with a small digital camera and an optical device, and the image sensor is mounted according to the shaking of the photographing device so that the image is not disturbed even when the subject is taken while moving and the image is not disturbed even by the minute vibration of the human body. In order to obtain a clear image by moving the drive frame in synchronization with the micro-vibration, the development of the image stabilization device is urgently needed.

The present invention is to solve the above problems, it is possible to be built in a miniaturized, lightweight camera such as a small digital camera, a mobile communication terminal, to enable the recording of a clear image even in the shaking of the imaging device by hand shaking, etc. An object of the present invention is to provide a shift stabilization device using an image sensor.

Another object of the present invention is to move the camera element according to the user's hand shake using a coil and a permanent magnet, the structure is simplified, the control is easy, and the shift-type hand shake using an image sensor that can reduce the manufacturing cost It is to provide a correction device.

Still another object of the present invention is to provide a shift stabilization device using a shift image sensor that can smoothly move the drive in the hand shake correction operation by installing a guide bar between the fixed body and the drive body.

It is still another object of the present invention to provide a shift stabilization device using a shift sensor that can improve a correction rate by allowing the camera to move in at least two directions when driving the driving body in motion. .

Can be made to prevent.

Looking at the other principle of operation in the above embodiment. When shooting a moving picture or a still image using a mobile communication terminal such as a small digital camera or a mobile phone with an optical system, when the image of the subject passes through the camera lens and is incident on the image sensor and is implanted, minute pulsation or movement of the human body or In order to compensate for the disturbance on the subject caused by the movement of the photographing device due to the movement of the photographing device due to the movement caused by the movement, in the present invention, the drive frame equipped with the image sensor is moved in the direction of the disturbance on the subject. The image imaged on the image sensor is constructed so that there is no deformation. The driving unit for driving the drive frame is generated by placing the coil in the magnetic field generated by the permanent magnet and applying a current by using a coil that generates an electromagnetic force to a VCM (Voice Coil Motor) and a permanent magnet that supplies the magnetic force. The driving frame is displaced to the corrected position by the driving force.

As shown in FIG. 2, the coil is formed in a right angle shape so as to generate the maximum driving force by increasing the effective coil side that can generate the driving force by extending the coil to one side, and driving in both directions in the first direction and the second direction. The first direction and the second direction of the coil and the permanent magnet is arranged vertically to enable independent movement in the first and second directions are made to converge to the correction position of the first direction and then to the second direction Control at the correction position in the first direction at the time of displacement to the correction position. That is, since it is possible to separately displace the drive unit in the first direction and the second direction, it is easy to implement the algorithm of the control unit to converge to the correction position, and by extending the coil of each drive unit in the vertical direction of the movement direction By generating a driving force, the connector portion 17, the mechanical load caused in the first and second frames and the load of the drive frame is made so that there is no difficulty in driving.

In addition, in the present invention, the first frame 11 and the second frame 12 are separated from the driving frame 10 to allow independent movement in the first and second directions, and the first frame is the main frame. The second frame 12 having a slide structure supported by (1) and movable in the first direction and on which the camera element 16 is mounted is supported by the first frame 11 and moved in the second direction. It is composed of a slide structure capable of delivering the camera element to the corrected position, the movement in the first direction uses a first frame that contains a second frame and the movement in the second direction is structurally separated from the first frame (11). By using the second frame 12, the driving frame 10 is synchronized with the subject image and corrected according to the degree of disturbance and the period on the subject, thereby providing an image having no afterimage. In addition, in order to increase the correction rate by synchronizing the drive frame of the compensator with the disturbance on the subject, it is important to have a response speed faster than the disturbance cycle on the subject to be linked, and to increase the weight of the rotor and the tension of the connector part connected to the main frame. It is possible to increase the reaction speed of the drive frame by reducing and increasing the driving force generated in the drive unit.
