Abstract: A camera module comprises a first lens barrel holding a first lens group configured to receive object light; a second lens barrel holding a second lens group disposed in a traveling direction of the object light with respect to the first lens group; a lens driving unit configured to drive the second lens barrel in a first direction along a first optical axis of the second lens group; and a guide for guiding a direction in which the second lens barrel is driven, wherein the first lens barrel has a first guide recess fitted in the guide, the second lens barrel has a second guide recess fitted in the guide, one of the first guide recess and the second guide recess fixes the guide in the first direction, and the guide slides in the first direction with respect to another of the first guide recess and the second guide recess.

Abstract: A camera module includes a first lens barrel holding a first lens group, a second lens barrel holding a second lens group, and a lens driver holding the perimeter of the second lens barrel to move the second lens group in a direction along a first optical axis of the second lens group. The size of the lens driver in a direction intersecting with the first optical axis (302) is smaller than the size of the first lens barrel in the direction intersecting with the first optical axis.

Abstract: An optical system includes the following: a first lens group including two or more lenses, having a positive power as a whole, and configured to pass object light; and a variable-focal-length lens configured to receive the object light that has passed through the first lens group, and capable of changing a focal length. An object that emits the object light undergoes focusing based on a power change in the variable-focal-length lens.

Abstract: 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 (L1) has positive refractive power. A fifth lens (L5) and a sixth lens (L6) each have negative refractive power. An object-side surface (L1F) of the first lens (L1) is a convex surface. At least one of an object-side surface and an image plane-side surface of each of a second lens (L2), a third lens (L3), a fourth lens (L4), and the fifth lens (L5) is an aspheric surface. An object-side surface (L6F) of the sixth lens (L6) is a concave surface and is an aspheric surface. An image plane-side surface (L6R) of the sixth lens (L6) is an optically planar surface throughout a region corresponding to an effective diameter of the image plane-side surface (L6R) of the sixth lens (L6).

Abstract: 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.
