Abstract
A lens holder for supporting a lens is put so as to slide on a side surface of a lens barrel in which an image sensor having a light receiving portion is arranged at the bottom, and the lens barrel and the lens holder are connected together by a connecting material. A fluid is filled in a space formed by the container composed of the substrate and the lens barrel, and the lens holder, and then a position of the lens with respect to the light receiving portion is controlled by controlling a volume of the fluid in the space to thereby move a position of the lens holder with respect to the lens barrel. Positioning of the lens is easily performed even when it is a compact configuration.
Claims14
A lens-position controller, comprising:
- a container;
- a lens support material for supporting a lens while covering said container, the lens support material being able to move along an optical axis direction of said lens;
- a fluid for mediating movement of said lens support material;
- and
- a controller for controlling the amount of fluid introduced to a space which is formed by said container and said lens support material;
- wherein a position of said lens in the optical axis direction is controlled by controlling the amount of fluid introduced to said space.
A lens-position controller, comprising:
- a container whose side surface is cylindrical in shape;
- a lens support material for supporting a lens, the lens support material being put so as to slide on the side surface of said container;
- a connecting material for connecting between said container and said lens support material over a circumference of the side surface thereof;
- a fluid which is filled in a space formed by said container and said lens support material;
- and
- a controller for controlling a volume of said fluid in said space,
- wherein a position of said lens in an optical axis direction is controlled by controlling the volume of said fluid.
An imaging module which is provided with an image sensor having a light receiving portion, and a lens, and guides a light entered into said lens to said light receiving portion, the imaging module comprising:
- a container whose side surface is cylindrical in shape, said image sensor being arranged at the bottom of said container;
- a lens support material for supporting said lens, the lens support material being put so as to slide on the side surface of said container;
- a connecting material for connecting between said container and said lens support material over circumferences of both side surfaces;
- a fluid which is filled in a space formed by said container and said lens support material;
- and
- a controller for controlling a volume of said fluid in said space,
- wherein a position of said lens with respect to said light receiving portion is controlled by controlling the volume of said fluid.
