Description

  The present invention relates to an optical device and an imaging device. More specifically, the present invention relates to an optical apparatus and an imaging apparatus having a camera shake correction unit that performs camera shake correction by moving an image sensor.

  In an optical apparatus such as a digital camera, various types of camera shake correction mechanisms have been conventionally employed in order to suppress disturbance of a captured image caused by a user's camera shake or the like.

As a specific example of such a camera shake correction mechanism, for example, a method of shifting a camera shake correction lens in a plane perpendicular to the optical axis in a direction to cancel the shake applied to the camera (for example, Patent Document 1). And a method of performing camera shake correction by swinging an optical system including the lens barrel using a so-called gimbal mechanism (see, for example, Patent Document 2). . In addition, a method of shifting the imaging device itself in a plane perpendicular to the optical axis without driving the lens in the lens barrel (see, for example, Patent Document 3) has been put into practical use.

  2. Description of the Related Art In recent years, optical devices such as digital cameras have been remarkably miniaturized, and accordingly, the space inside the optical system and the camera has been narrowed, and it has become difficult to ensure a sufficient space for performing camera shake correction. Further, in order to enable long-time shooting with a small battery, further power saving is required, and it is necessary to reduce the power used for camera shake correction.

  However, since the camera shake correction mechanism of Patent Documents 1 and 2 performs the camera shake correction by moving the lens group or by swinging the optical system including the lens barrel, such movement is limited to a limited space. Providing the mechanism requires high accuracy and is inconvenient for downsizing the optical device. Also, since the optical system is heavy, power consumption when moving the optical system cannot be ignored.

  On the other hand, there is a method of performing camera shake correction by moving an image sensor in parallel as disclosed in Patent Document 3 above. Since this method does not require a dedicated optical system and the imaging element is lightweight, it can be said that this method is suitable for an optical device, particularly an optical device for exchanging lenses.

  However, when camera shake correction is performed by moving the image sensor, it is necessary to provide a margin corresponding to the movement in the cable connecting the image sensor and the substrate in addition to downsizing the camera shake correction mechanism itself. For this reason, a space for storing the bent cable is required, and securing such extra space has become an obstacle to further downsizing. In addition, since the moving means such as a motor or an actuator deflects the cable, there is a problem that the load on the moving means increases, resulting in an increase in power consumption.

  The present invention has been made in view of the above-described problems, and is small in size and power consumption, in which an image-free image can be obtained by minimizing a cable connecting a substrate on which an image sensor is mounted and another substrate. An object is to provide a small number of optical devices and imaging devices.

There is no need to do it. That is, the space for the cable becomes extremely small, and the load on the moving means for moving the image sensor can be reduced. As a result, it is possible to provide an optical apparatus having a camera shake correction unit that is small and consumes less power.

It is possible to provide an optical device with a camera shake correction function capable of performing communication between them.

  According to the invention described in claim 5, since the communication of the optical communication means is performed after the image pickup by the image pickup device, after moving the image pickup device to a predetermined position and then being fixed, it is possible to communicate reliably. A small optical device with an image stabilization function can be provided.

  According to the invention described in claim 6, since the wireless communication means communicates by electromagnetic waves, there are few restrictions on the mounting arrangement of the transmission unit and the reception unit, and communication is performed after the operation of the camera shake correction unit is stopped.

  The reference base plate 181 is fixed to the inside of the digital camera 1 at the bottom 181a. On the reference base plate 181, an H actuator 185 composed of a SIDM (Smooth Impact Drive Mechanism) composed of a piezoelectric element and an axis for moving the H base plate 182 in the horizontal direction (X-axis direction) is disposed. . The H actuator 185 and the H base plate 182 are fitted by an H fitting portion 182b, and the H base plate 182 moves horizontally by applying a drive pulse to the H actuator 185. The H sliding portion 182c on the opposite side across the H fitting portion 182b of the H base plate 182 and the image sensor 153 contacts the H guide portion 181b of the reference base plate 181 and the H base plate 182 moves in the horizontal direction.

  On the H base plate 182, a V actuator 186 configured by a SIMDM (Smooth Impact Drive Mechanism) composed of a piezoelectric element and an axis for moving the V base plate 183 in the vertical direction (Y-axis direction) is disposed. . The V actuator 186 and the V base plate 183 are fitted by a V fitting portion 183b, and the V base plate 183 moves vertically by applying a drive pulse to the V actuator 186. The V sliding portion 183a on the opposite side across the V fitting portion 183b of the V base plate 183 and the image sensor 153 contacts the V guide portion 182a of the H base plate 182, and the V base plate 183 moves in the vertical direction. Sometimes it becomes a sliding surface. The V base plate 183 is fitted into the opening 182 d of the H base plate 182.

  The structures and driving methods of the H actuator 185 and the V actuator 186 are described in detail in, for example, Japanese Patent Application Laid-Open No. 7-274543, and are omitted here.

  Next, a circuit configuration of the digital camera 1 that functions as an imaging apparatus according to the present invention will be described with reference to FIG. FIG. 3 is a circuit block diagram of the digital camera 1 that functions as an imaging apparatus according to the present invention. In the figure, the same parts as those in FIGS. 1 and 2 are given the same numbers.

  The camera control unit 100, which is a control unit of the digital camera 1, includes a CPU (Central Processing Unit) (not shown), a work memory, and the like, reads a program stored in the storage unit 101 into the work memory, and performs digital camera according to the program. Centralized control of each part of 1.

  The camera control unit 100 receives inputs from the power switch 111, setting dial 112, jog dial 113, determination switch 114, AS setting switch 115, zoom switch 116, release switch 110, and the like provided on the operation unit 60. The entire digital camera 1 is controlled, the power supply unit 120 is controlled to supply power to each part of the camera, and the personal computer, printer, and image data via an external interface (I / F) 125 such as a USB (Universal Serial Bus). Communicate such as transfer.

  The camera control unit 100 manages a sequence related to shooting. The camera control unit 100 controls the image capturing operation of the image sensor 153 via the synchronization signal generator 27 and the image sensor drive unit 23. The synchronization signal generation unit 27 generates a basic synchronization signal necessary for signal processing, and the image sensor driving unit 23 receives the synchronization signal generated by the synchronization signal generation unit 27 and the control signal from the camera control unit 100. Thus, a detailed timing signal for driving the image sensor 153 is generated.

  In the present invention, the image sensor may be a solid-state image sensor such as a CMOS sensor or a CID sensor instead of the CCD. The analog signal image acquired by the image sensor 153 is converted into a digital signal after noise removal processing by the A / D converter 21. The transmitter 22a of the wireless communication unit 22 is mounted on the imaging substrate 187, which is the first substrate of the present invention, and the receiver 22b is mounted on the main substrate 160, which is the second substrate of the present invention.

  The transmission unit 22a has a buffer memory, temporarily stores the image converted into a digital signal by the A / D conversion unit 21 in the buffer memory, and sequentially wirelessly transmits the image. The receiving unit 22b also has a buffer memory, stores digital signals received wirelessly in the buffer memory, and sequentially outputs the digital signals of the images to the image processing unit 151. In the present embodiment, as an example, if the A / D converter 21 converts the signal into a 12-bit digital signal, the 12-bit connection necessary for transmitting the image signal from the imaging board 187 to the main board 160 is used. Can be made unnecessary.

  The wireless communication method performed between the transmission unit 22a and the reception unit 22b may be either an optical communication method such as a method of modulating infrared rays or a method of modulating electromagnetic waves. As an example of the optical communication system, the standard IrDA defined by IrDA (Infrared Data Association) is used, and as the system for modulating electromagnetic waves, the IEEE (Institute of Electrical and Electronics Engineers) standards IEEE802.11E80E Etc. are applicable. In the present invention, since communication is performed between two specific persons at a very short distance between the transmission unit 22a and the reception unit 22b, the invention is not limited to these standards, and a simplified method may be used.

  The transmission unit 22 of the optical communication system has a light emitting unit using a light emitting element such as an infrared LED or an infrared semiconductor laser, and the receiving unit 25 has a light receiving unit using a light receiving element such as a photodiode or a phototransistor. is doing. As shown in FIG. 1, the light-emitting part of the transmission part 22a and the light-receiving part of the reception part 22b are arranged at opposing positions. In the case of a method of modulating electromagnetic waves, the transmission unit 22a has a small transmission antenna, and the reception unit 22b has a reception antenna. In the case of the electromagnetic wave method, it is not always necessary that the transmission unit 22a is located opposite the reception unit 22b as shown in FIG. 1, and the transmission unit 22a and the reception unit 22b can be arranged on any surface within a range where communication is possible.

  The image processing unit 151 has image processing functions such as gamma correction, contour correction, and image compression. These image processes are also performed by commands from the camera control unit 100. The camera control unit 100 performs image processing on the image output of the image sensor 153 received by the receiving unit 22b, temporarily records it in the image memory 26, and finally records it in the memory card 156.

  The camera control unit 100 controls the AF operation of the imaging optical system 211 via the optical system driving unit 212 based on the focus information and exposure information obtained from the image output of the imaging element 153 received by the receiving unit 22b, and the aperture The diaphragm 221 is controlled via the drive unit 222.

  In addition, the camera control unit 100 displays the live view of the image captured by the image sensor 153 via the image display unit 132 or the rear monitor 131 or the rear monitor 131 according to the setting of the rear monitor setting switch 117. The images displayed on both sides and recorded in the image memory 155 are displayed on the rear monitor 131 as an after view, and the image recorded on the memory card 156 is displayed on the rear monitor 131 as a reproduced image.

  Finally, the camera control unit 100 corrects camera shake by driving the camera shake correction unit 180 based on the camera shake information detected by the camera shake detection unit 171 in accordance with the setting of the AS setting switch 115.

  FIG. 4 is a schematic vertical cross-sectional view of the B-B ′ portion of the schematic diagram of the digital camera 1 described in FIG. FIG. 4 is a schematic diagram for explaining mounting between substrates in the first embodiment of the present invention, and illustration of other components is omitted.

  The wireless communication unit 22 is an optical communication system, the transmission unit 22a has a light emitting unit using a light emitting element such as an infrared LED or an infrared semiconductor laser, and the reception unit 22b is a light receiving element such as a photodiode or a phototransistor. It has a light receiving part using. As shown in FIG. 1, the light-emitting part of the transmission part 22a and the light-receiving part of the reception part 22b are arranged at opposing positions. A light receiving element having a wide light receiving range is selected so that the light receiving unit of the receiving unit 22b can receive light even if the light emitting unit on the imaging substrate 187 is moved in the X axis direction and the Y axis direction by the camera shake correction unit 180. Or you may arrange | position a some light receiving element in the position facing the movement range of the transmission part 22a.

  A connector 401 is mounted on the imaging substrate 187 and a connector 402 is mounted on the main substrate 160 and connected by a cable 403. Signals transmitted through the cable 403 include a control signal from the camera control unit 100, a synchronization signal from the synchronization signal generation unit 27, and a power supply supplied from the power supply unit 120. Since the cable 403 is composed of a belt-like flexible substrate, the flexible substrate absorbs the amount of movement of the imaging substrate 187 in the X-axis direction by the camera shake correction means by the deflection. In the embodiment of the present invention, since the 12-bit digital signal converted by the A / D converter 21 is wirelessly transmitted by the wireless communication unit 22, the number of signals transmitted by the flexible substrate is reduced, and the flexible substrate is made small. be able to. For this reason, the space for housing the cable 403 can be made small, and the stress applied to the cable 403 can be made extremely small.

  Note that the imaging substrate 187 may be formed of a rigid flex substrate in which a hard substrate and a flexible substrate are integrally formed, or a multilayer FPC. In that case, the image sensor 153 is mounted on the flexible substrate by thermocompression bonding, and the image sensor drive unit 23 and the transmission unit 22a are mounted on the hard substrate. The cable 403 and the main board 160 may be connected by thermocompression bonding. Further, the position of the cable 403 is not limited to this position, and the movement amount moving in the Y-axis direction may be absorbed by deflection.

  FIG. 5 is a schematic diagram for explaining mounting between substrates in the second embodiment of the present invention.

  In the second embodiment in which the wireless communication unit 22 is an electromagnetic wave system, restrictions on the arrangement of the wireless communication unit 22 are reduced. As an example, FIG. 5 shows an example in which the receiving unit 22b is disposed on the surface of the main substrate 160 opposite to the imaging substrate 187. Thus, in the electromagnetic wave system, the receiving unit 22a and the transmitting unit 22a can be arranged on the imaging substrate 187 and the main substrate 160 without facing each other. Other members are the same as those in FIG.

  FIG. 6 is a flowchart showing a flow of processing at the time of photographing performed by the digital camera 1 shown in FIGS. 4 and 5.

  In FIG. 6, processing after the digital camera 1 is turned on, the shooting mode is selected, and the camera enters a shooting standby state will be described. It is assumed that the camera shake correction setting is ON.

The photographer operates the zoom switch 116 to set a desired angle of view while confirming the photographing range with the preview image displayed on the eyepiece 121a or the rear monitor 131, and the release button 110 is pressed halfway (SW1). ON) (step S101; Yes). The camera control unit 100 detects the focal point, instructs the optical system driving unit 212 to move at the focal position D, and focuses the imaging optical system 211. The camera control unit 100 performs automatic exposure control, sets an exposure time (step S102), and determines whether or not the release button 110 is fully pressed (SW2 is on) (step S103).
If SW2 is not on (step S103; No), the process returns to step S101. When SW2 is on (step S103; Yes), the process proceeds to step 104, and the camera control unit 100 starts camera shake correction.

  The camera control unit 100 moves the position of the image sensor 153 by the camera shake correction unit 180 according to the amount of camera shake detected by the camera shake detector 171 (step S104), opens the diaphragm 221 by a predetermined amount, and exposes the image sensor 153 for a predetermined time. Then, imaging is performed (step S105). When the exposure time ends, the movement of the image sensor 153 by the H actuator 185 and the V actuator 186 of the camera shake correction unit 180 stops, and the image sensor 153 is fixed at that position (step S106). At this time, since the driving of the H actuator 185 and the V actuator 186 by the camera shake correction unit 180 is stopped, there is no generation of electromagnetic waves that affect the wireless communication unit 22.

  Next, the camera control unit 100 instructs the image sensor driving unit 23 to read out the captured image signal, and the image signal is read out from the image sensor 153 for each pixel (step S108). The image signal for each pixel is A / D converted by the A / D converter 21, and the signal is sequentially transmitted from the transmitter 22a (step S109). The image processing unit 151 sequentially stores the image data received by the receiving unit 22b in the image memory 26. When the reception of the image data of all the pixels is completed (step S110), the image processing unit 151 performs white balance correction, gamma correction, and image data. Necessary image processing such as compression is performed (step S111). When the image processing ends, the camera control unit 100 records an image on the memory card 156 (step S113). This completes the shooting operation for one frame.

  Next, a third embodiment using an optical communication system will be described.

  In the first embodiment of the present invention that uses the optical communication method described in FIG. 4, the light receiving unit of the receiving unit 22b has a wide light receiving range, and the transmitting unit 22a is operated by the camera shake correcting means 180 in the X axis. The receiving unit 22b can receive light even if it moves in the direction and the Y-axis direction. As a third embodiment of the present invention, a flow of processing at the time of photographing for communicating by moving the transmitting unit 22a to a predetermined position facing the receiving unit 22b during wireless communication will be described with reference to FIG. It should be noted that, since the same processing as that in FIG. 6 is performed after the completion of the imaging in step S105 until the camera shake correction is completed in step S106, the same processing is given the same number and will be described from step S107.

  In step S107, the camera control unit 100 instructs the camera shake correction unit 180 to move the imaging substrate 187 to a position where the light emitting unit of the transmitting unit 22a and the light receiving unit of the receiving unit 22b face each other (step S107). By moving to a predetermined position where transmission and reception can be performed in this manner, for example, the light receiving range of the light receiving unit is narrow, and communication is possible even when light cannot be received when the transmission unit 22a moves. The subsequent processing is the same as in FIG.

  As described above, according to the present embodiment, it is possible to minimize the cable for connecting the substrate on which the image sensor is mounted and the other substrate by performing wireless communication. And an imaging device can be provided.

  Note that although a digital camera has been exemplified as this embodiment, the present invention can also be applied to a mobile phone with a digital camera function, a video camera, and the like.
