Description

  The present invention relates to a photographing apparatus including a photographing unit having an image blur correction mechanism and a portable device including the photographing apparatus.

  2. Description of the Related Art Conventionally, various camera shake correction mechanisms have been employed in digital cameras and the like in order to suppress disturbances in captured images caused by user shake (see Patent Documents 1, 2, and 3).

  As such a camera shake correction mechanism, there is one that employs a so-called gimbal mechanism so that a holding module holding a photographing lens can be rotated in a pitching direction and a yawing direction.

  However, in the case of the gimbal mechanism as disclosed in Patent Document 1, it is necessary to arrange rotating joints and the like that freely rotate at four locations on the top, bottom, left, and right of the holding module. There is a tendency.

  Therefore, the shaft point that is one point along the outer periphery of the holding module is supported in a swingable manner, and the first point and the second direction that are different from the axial point along the outer periphery of the holding module are separated from each other. A drive structure for driving the holding module via each of the first drive point and the second drive point has been filed by the present applicant, and Japanese Patent Application Nos. 2006-269712, 2006-269713, and 2006-269714. Japanese Patent Application No. 2006-269715 has been proposed as an unpublished application. Further, the present applicant has made further improvements to these prior applications to improve the position detection accuracy of the holding module when the holding module is oscillating, and image blur correction disclosed in Japanese Patent Application No. 2007-035341. Proposed as a unit. When the drive structure proposed in these applications is realized, the photographing unit having an image blur correction function can be reduced in size and can be mounted on a portable device.

  FIG. 6 is a diagram for explaining the operation of the photographing unit having the image blur correction function.

  6 (a) and 6 (b) show what kind of trouble occurs in the positional relationship between the lens and the sensor when blurring occurs, and FIG. 6 (c) shows It shows how blur is corrected by an image blur correction unit comprising a lens and a sensor.

  When camera shake does not occur as shown in FIG. 6A, the optical axis of the lens and the optical axis of the light receiving surface (sensor surface) of the sensor coincide with each other, and subject light is imaged at the correct position. On the other hand, when camera shake occurs, the lens or sensor surface rotates in the direction of the arrow as shown in FIG. 6B, and the optical axis of the lens deviates from the optical axis of the sensor surface. No image formation.

  Therefore, when image blur correction unit is mounted on a portable device and camera shake occurs during shooting, an image blur correction unit composed of a lens and a sensor is operated as a gyro as shown in FIG. 6C. The subject light is always focused at the correct position on the sensor surface. When the image blur correction unit is mounted on a portable device such as a camera-equipped mobile phone in this way, even if the portable device is rotated by a shooting operation, the posture of the image blur correction unit is always maintained at the posture immediately before the shooting operation, and suitable shooting is possible. Is done.

  By the way, a digital camera equipped with the above photographing unit may be accidentally dropped or bumped while being carried. In such a case, the photographing unit mounted inside the digital camera may be damaged by impact.

  FIG. 7 is a diagram for explaining a mounting structure of the photographing unit 200I that is currently conceivable when the photographing unit 200I is mounted on the mobile phone 100I.

  As shown in FIG. 7, both the photographing unit 200I and the camera shake detection board 182I are firmly attached so that the state of camera shake can be detected by the camera shake detection sensor and image blur correction can be accurately performed by the photographing unit. It can be considered to be attached to a housing. In this case, if the mobile phone is accidentally dropped, the photographing unit 200I may be broken.

  In order to avoid this, for example, a buffer member such as a spring member may be inserted between the photographing unit 200I and the seating surface of the housing.

However, when the photographing unit 200I is attached via a spring member as shown in FIG. 7, the image blur correction is applied to the photographing unit 200I according to the detection result of the shake of the gyro sensor 182 mounted on the camera shake detection board 182I. Even if the correction is performed, an error due to the elastic force of the spring member may appear and image blur correction may not be performed well.
