Abstract: In a camera module having an image stabilization mechanism, both of miniaturization and thinning are achieved, while adopting a structure of driving an entire of a lens group in a direction perpendicular to an optical axis direction. An image stabilization portion (4) of a camera module (50) includes an OIS base (14), an OIS movable plate (12), and guide balls (15) which support the OIS movable plate (12) so as to be movable in a plane perpendicular to an optical axis direction with respect to the OIS base (14).

Abstract: An optical section (3) and a lens holder (4) are fixed to each other in a state where the lens holder (4) is at an intermediate position within a movable range so that the optical section (3) does not come into contact with an image pickup section (10) in a case where the lens holder (4) is driven within the movable range. This makes it possible to provide (i) a camera module in which it is possible to reduce the influence of a tilt that occurs in the vicinity of an infinite-distance side mechanical end and also reduce the influence of a tilt that occurs at an intermediate position away from the infinite-distance side mechanical end and a macro side and in which image pickup lenses are attachable with high positional accuracy and (ii) a method for producing a camera module.

Abstract: A lens barrel (3) includes a local maximum outer diameter section (3e) and a maximum outer diameter section (3a). The maximum outer diameter section (3a) is provided in a portion of an area of the local maximum outer diameter section (3e) which portion includes an area corresponding to an outer periphery of an image pickup lens (2m) which is the largest in lens diameter. This achieves a further size reduction while achieving a high-accuracy installation of a lens barrel.

Abstract: In a camera module 1 of the present invention, a mechanical shutter 2 is provided above a top surface of a lens unit 3, and a protrusion section formed to an end of a lens 31 is held in a depression section formed on a back surface of the mechanical shutter 2. With the arrangement, it is possible to cause the camera module 1 employing the mechanical shutter 2 to be smaller and thinner at the same time.

Abstract: A camera module 1 of the present invention includes a moving magnet type mechanical shutter 2 and a lens unit 3 (lens drive section) for driving a lens by electromagnetic force. A magnetic field for driving the lens is set so that a light path is closed by a shutter fin while a magnetic field leaked from the lens unit 3 is acting on a drive mechanism of the mechanical shutter 2. With the configuration, the leak magnetic field leaked from the lens unit 3 causes the light path to be closed at a faster speed by the shutter fin of the mechanical shutter 2. Accordingly, generation of a smear can be prevented by the camera module including the lens drive section and the moving magnet type mechanical shutter, which are driven by the electromagnetic force.

Abstract: A camera module includes a lens drive device that moves an image pickup lens along an optical axis. The lens drive device has electromagnetic drive means that drives the image pickup lens by electromagnetic force with use of a coil and a magnet. The image pickup lens has a planimetrically rectangular shape. The magnet and the coil are disposed along each of at least one pair of opposite sides of the rectangular shape. By utilizing the characteristics of the image pickup lens having a rectangular shape, the magnet and coil of the lens drive device are disposed along each of the at least one pair of opposite sides. This makes it possible to provide a camera module having a lens drive device with a smaller footprint (amount of space that the camera module uses) than in the case of an arrangement of magnets at the corners of the image pickup lens.
