In an image display device including an image taking window portion, the image taking window portion for an image taking camera is disposed within the image display region, and an outer diameter of a frame portion is set to satisfy a specific condition based on an angle of view of the image taking camera.

Image display device

It is possible to (i) cause a sixth lens to more effectively correct various aberrations and (ii) make an optical overall length shorter. A first lens (L) has positive refractive power. A fifth lens (L) and a sixth lens (L) each have negative refractive power. An object-side surface (LF) of the first lens (L) is a convex surface. At least one of an object-side surface and an image plane-side surface of each of a second lens (L), a third lens (L), a fourth lens (L), and the fifth lens (L) is an aspheric surface. An object-side surface (LF) of the sixth lens (L) is a concave surface and is an aspheric surface. An image plane-side surface (LR) of the sixth lens (L) is an optically planar surface throughout a region corresponding to an effective diameter of the image plane-side surface (LR) of the sixth lens (L).

A plurality of lenses constituting a lens unit () are fixed to each other with use of an adhesive () applied between the plurality of lenses. The lens unit () is incorporated into an actuator () through an opening () of the actuator () and is held inside the actuator () so as to face directly an inner wall surface of the actuator ().

Camera module, electronic device in which camera module is mounted, and method for manufacturing camera module

A camera module () of the present invention includes: an optical section () including a lens section (); and an OIS section () correcting misalignment of an optical axis. The lens section () has an image height-optical distortion curve in which an optical distortion is a positive maximum value in an intermediate image height region and the optical distortion gradually decreases from the maximum value as an image height approaches a maximum image height.

Camera module and image capturing device having decreased distortion in the vicinity of the maximum image height

In a camera module, the position of image pickup lenses at an end at infinity is defined by contact between a bottom surface of a lens barrel and a surface of a sensor cover. This makes it possible to realize a camera module having image pickup lenses positioned with a high degree of accuracy.
