New type of description: [Technical field of new type] This work relates to an image shake compensation 5 which is applicable to a camera shake device such as a digital camera or a mobile phone with a camera head. An image shake compensation device such as a shake compensation unit, an image pickup device including the image shake compensation device, and a portable device including the image capture device. [Prior Art] In the past, in order to suppress a captured image caused by a user's hand shake or the like, various hand shake compensation mechanisms have been employed in digital cameras (see Patent Documents 1, 2, and 3). As such a hand shake compensation mechanism, a so-called "150,000-way joint mechanism" is employed in order to rotate the holding member for holding the image pickup lens in the pitch direction and the yaw direction. However, in the case of the universal joint mechanism disclosed in the above-mentioned Patent No. 1, it is necessary to arrange a freely rotatable rotary joint or the like at the top, bottom, left, and right of the holding unit. Therefore, there is a tendency for the hand shake compensation mechanism to be enlarged in any case. In addition, in order to achieve miniaturization, there is a problem that the bearing portion of the above-described rotary joint is weakened. Therefore, the applicant has applied a driving structure for driving the holding assembly through the first driving point and the second driving, respectively, and the first driving point and the second driving point are swingably supported as an axis along a point of the outer circumference of the holding assembly. At the same time, from the above-mentioned pivot points along the outer circumference of the holding assembly to the first direction and the second direction which are different from each other, M361037, the patent application is filed JP2006-269712, and the patent application Jp2〇〇6_269713 No., patent application JP2006-269714, patent application JP 2〇〇6_269715, and the like. Further, the applicant has added further to these prior applications; = improved 'production' (4) G7_G3534 m image jitter compensation unit proposes a technique for improving the position detection accuracy of the holding assembly while maintaining the component swinging . In the drive structure proposed in these applications, if the image compensation unit is implemented with a ===, the size of the image blurring compensation unit can be reduced, and the image can be mounted on the portable code type &X. 0. FIG. 8 is a view for explaining the operation of the image blur compensation unit. (a) of the unit ^ and (1) of FIG. 8 indicate that the image compensation is not performed on the image-shake compensation image:: how:: the transmission is provided with a lens and a sensor 15 20 # (a) of FIG. 8 does not occur When the hand shakes, the motion compensation unit is not mounted, and the light-receiving surface of the silk-phase sensor is transmitted through the clock. (Photosensitive contrast is shown in Fig. 2, so that the subject light is imaged at the correct position. When the compensating unit shown in (1) of Fig. 8 is not mounted, when the second-hand jitter is used, the image is shifted by the optical axis of the optical surface of the lens and the optical axis of the lens. In the case where the image is shaken by the device like the shake compensation unit, the lens is moved by the lens and the touch compensation W7L as a gyroscope. Even if the camera is rotated, the Migma compensation unit is reversed. Rotate in the direction to make the subject light, kind of silly: the correct position on the photosensitive surface. In this case, if the portable device is equipped with the =Corporation Compensation Unit, then even if the portable device is shaken by the shooting operation (4), the position of the unit will be met.

In the present embodiment, the image blur compensation unit 200, the CPU 180, the gyro sensor 182, and the driver DR constitute an example of the image shake compensation device of the present invention, and the image shake compensation device and the input controller 13 ( The image signal processing unit, the 10 video encoder 150, the image display device 16A, the liquid crystal panel 1〇1, the media controller 190, and the 5 recorded media 19〇a constitute an example of the imaging device of the present invention. A CPU 180 transmits a processing instruction to various elements of the mobile phone 100 shown in Fig. 2 to control various elements. For example, when the option button 104 of FIG. 1 is pressed in the state of the imaging mode set to perform imaging, the driver DR 1 DR2 is assigned to the CCDU 2 provided in the image shake compensation unit 200 from the cpui 8 ,, and the driver DR 1 DR2 is not indicated. The holding unit (described below) provided in the image-shake compensating unit is swung in the direction of eliminating the hand shake detected by the gyro sensor 182 to compensate for the hand shake while shooting. The configuration of the image shake compensation unit 2A will be described in detail later. 20 The option of receiving (A) of Fig. 1 is pressed, and the CPU (10) sets the electronic shutter in the == compensation unit (4) CCDU2, and starts shooting. 'The gyro sensor 182 detects the pressing option. (4) Hand shake direction and notify CPU (10). The cpui 8G receives the detection result of the gyro sense 13 M361037 detector 128, and notifies the drivers dri and DR2 of the compensation direction, and causes the drivers DR1 and DR2 receiving the notification to drive the coils in the image compensation unit 2 (described below). According to the holding component (described below) in the shake image shake compensation unit 2, the image is taken while swinging. Thus, by compensating for the hand shake when the option 5 button 104 is pressed, the CCD 112 can image the subject light that is not shaken. Further, the CCD 112 receives the subject light that has passed through the photographic lens 100a within the shutter second of the electronic shutter, and reads the subject signal based on the subject image of the subject light as an analog signal. The subject signal generated by the CCD 112 is converted into digital photographic image data by the A/D conversion unit 113, and the converted photographic image data is sent to the image signal processing unit 140 through the input controller 130. The image signal processing unit 14 performs image processing such as adjustment of the rGB level and gamma adjustment on the image data, and further performs compression processing on the image data after the image processing. The compressed image data is temporarily sent to the storage 15 170. The storage unit 170 includes: a program stored in the mobile phone ι, or a high-speed SDRAM which is used as an intermediate buffer; and stores various functions such as data for the function table or the user's setting contents. use

The SRAM of the storage; the VRAM that stores the compressed image data. The VRAM 20 is divided into a plurality of areas, image data is sequentially stored in a plurality of areas, and the stored image data is sequentially read by the video encoder 15 or the media controller 19A. The video encoder 150 acquires the compressed image data from the memory 17' in accordance with an instruction from the CPU 180, and converts the compressed image data into a data format which can be displayed on the 14 M361037 liquid crystal panel 101. The converted image data is sent to the image display device 160, and the image indicated by the image data is displayed on the liquid crystal panel 1〇1 through the image display device 160. The media controller 190 records the compressed image data stored in the storage 170 on the recording medium 190a or the image data recorded on the recording medium 190a. Further, the telephone number is input using the push button 1〇5 shown in (A) of Fig. 1. If the OK button 1〇7 is pressed, the telephone number is set and communication with the opposite device is started. At this time, the CPU 180 transmits the communication information such as the telephone number of the hand &gt; 100 and the input telephone number to the first transmission/reception unit 1A, and the communication resource 10 is converted into a radio wave and transmitted to the first antenna 1〇3a. Further, a radio wave is emitted from the first antenna 10a. The radio wave emitted from the first antenna 1〇3a is transmitted to the telecommunication office through a shared antenna (not shown) provided in various places such as a building or a utility pole, and the counterpart device that establishes and assigns the designated telephone number at the telecommunication office connection. 15 Once the connection with the other party device is established, the sound emitted by the user to the mobile phone 100 is collected by the microphone 121, and the collected sound is converted from the dielectric surface 12 to the radio wave representing the sound data, and the first day of transmission through the first transmitting and receiving unit 103 Line l〇3a is sent to the other device. Further, the sound wave for sound received through the first antenna 103a is converted into sound data by the face portion 12A, and is emitted as sound 2 from the speaker 122. In the first transmitting/receiving unit 1 〇3 and the first antenna 1 〇3a, not only the sound data can be transmitted and received but also the mail address can be used instead of the telephone number, and the mail information indicating the mail can be transmitted and received. The mail data received by the first antenna 103a and digitized by the first transmitting and receiving unit 103 is stored in the memory 170 through the input controller 13A. 15 M361037 In addition, in the mobile phone 100, the communication interface (the first transmission/reception unit 103 and the first antenna 103a) that communicates with the counterpart device such as the other mobile phone through the telecommunication office may be independent of the telecommunication office, but A wireless communication interface (second transceiver unit 、9, second antenna 5 〇9a) that communicates via short-range wireless communication. As a communication interface for short-range wireless communication, infrared communication or Bluetooth can be applied. In the present embodiment, infrared communication is applied as a communication interface, and when infrared rays directly transmitted from other mobile phones or the like are received by the second antenna 1A, the second transceiver unit 1〇9 picks up an electric signal based on the received infrared rays. And convert it into digital data. On the contrary, when the data is transmitted to the external device, the data is transmitted to the second transceiver unit 1〇9, and the data is converted into a radio wave at the second transceiver unit 1〇9, and is transmitted from the second antenna 1〇%. Once the infrared rays representing the image are received at the second antenna 10a, the second transceiver portion 109 converts the infrared-based electrical signals into image resources. The converted image data is sent to the image display device 160 in the same manner as the captured image data, and the image indicated by the image data is displayed on the liquid crystal panel 101 and recorded on the recording medium 19A via the media controller 190. The mobile phone 100 basically has the above configuration. 20 Next, the configuration of the image blur compensation unit 200 constituting a part of the photographing device provided in the mobile phone i 。 。 will be described in detail.

The first axis (ie, the pitch direction) around the joint shaft point pB and the second drive point D2 is rotated within the first maximum angle (±1.5 degrees in this example), and the second drive mechanism (with 20) The first arm ARM2 is transmitted through the second driving point D2 such that the holding assembly surrounds the connecting shaft point PB and the second axis of the first driving point D1 within a second maximum angle (in this example, the first maximum angle is greater than The soil is rotated 15 degrees, whereby the holding assembly 202 can be rotated more in the pitch direction. In this way, since the swing 20 . M361037 of the maximum swing portion indicated by the symbol P in FIG. 5( b ) can be suppressed to be smaller than the conventional one, the body of the portable device can be assembled even thinner. 5 image jitter compensation unit. Fig. 6 is a view showing an image blur compensating unit 2A that is compactly assembled to a mobile phone that is thinner than ever. Fig. 7 is a diagram for explaining the basis of the first maximum compensation angle being set to ± 1.5 degrees. U) of Fig. 6 shows the inside of the lower casing of the unloading T mobile phone. Fig. 6(b) shows the surroundings of the image capturing unit 200.

10 As shown in Fig. 6, it can be installed in the corner of the mobile phone (10) without gaps. The image compensation unit 2 (10) is horizontally long and the vertical direction X is shortened in the vertical direction of the mobile phone (10). A space like jitter compensation unit is loaded into the space. In the case of a device, the hand of the phone in the pitch direction is shaken when the hand is shaken &quot; and the second drive == the range of the compensation angle (the first drive will be like the jitter compensation ^ 2〇n swing range) is different at the design stage, The opening of the compensation unit; shape: When the next two are installed in portable equipment, it is possible to study in order to improve space efficiency. &gt; Figure 7 illustrates the basis for this degree of creativity. The first-maximum swing angle of H乍 is 1·5 20 FIG. 7 is a diagram showing the holding of FIG. 9 (small diagram, and the digital camera shown in (1) indicating the jitter angle of the mobile phone of FIG. 9 A diagram of the difference between the jitter state of the mobile phone and the difference of FIG. 9. The frequency components of the two states are heretofore, as described in the previous example regarding the digital camera, as long as the monitor data of (b) of FIG. 9 21 M361037 is considered to be ±0.5 degrees. The above maximum swing angle can be 'but if the difficulty of the grip of the above mobile phone is taken into consideration, when the same compensation range as the shake angle (±0.5) used by the digital camera is used for the mobile phone, the case of FIG. 8 cannot be appropriately performed. The horizontal axis of (a) is after the hand shake compensation of the state 5 after 500 ms. However, the difference in the frequency components of the (b) of the ®17 is almost indistinguishable.

10 From these points, it is also considered that for the mobile phone, it is sufficient to hold the same image compensation range of ±0.5 degrees with the digital camera, but considering that it is difficult to hold the mobile phone 'vibration becomes large, the maximum swing angle is set. It is 3 times 1.5 degrees of 5 degrees, which ensures a sufficient compensation range. So, 15

20 When the image shake compensation unit of the present embodiment is mounted on a mobile phone, no matter what kind of mobile phone, the hand shake can be reliably compensated. Here, in the method of performing hand shake compensation by eccentricity of a part of the imaging lens known in the related art to the optical axis orthogonal direction, if the eccentric amount (compensation amount) is set to be large, the image is bad, but according to the present creation, Since the photographic lens and the CCD body are moved to compensate for the hand shake, even if the amount of eccentricity is increased, the image is not made to be bad, and a good image can be obtained. In addition, in the method of eccentrically compensating the photographic lens and the CCD, which are well known in Korea, the eccentricity is increased, and it is necessary to increase the CCD size. However, according to the present creation, even if the size of the CCD is not increased It is also able to compensate for the relatively large hand shake of the eccentricity. As the above, the compensation range of the occurrence condition of the hand 2 suitable for the pitch direction and the yaw direction is realized, and the image shake compensation unit having a larger compensation ratio than the digital camera has the image shake of the image shake compensation unit. The compensation device further realizes an imaging device including the image blur compensation device and a portable device including the imaging device.
