An image pickup apparatus is provided which is characterized by compact configuration, high performance and minimized noise, and which has an optical unit coupled to an image pickup unit through a drive element, and has the same outside diameter as the optical unit, wherein the apparatus drives the optical unit by expanding and contracting the drive unit in a direction of an optical axis of the optical unit.03-19-2009
20100157133IMAGE CAPTURING DEVICE - An image capturing device, including an rectangular image capturing element having long sides and short sides; an image capturing optical system forming an image of a subject on the rectangular image capturing element; a first driving device which moves the rectangular image capturing element in a first direction slanted by a predetermined angle from the long side and the short side of an outer shape of the rectangular image capturing element in a plane perpendicular to an optical axis of the image capturing optical system; and a second driving device which moves the rectangular image capturing element in a second direction slanted by a predetermine angle from the long side and the short side of the outer shape of the rectangular image capturing element in the plane perpendicular to the optical axis of the image capturing optical system, but the second direction differs from the first direction.06-24-2010
20110013063IMAGING DEVICE AND IMAGING DEVICE MANUFACTURING METHOD - A technique capable of satisfying both higher functionality and higher accuracy in a compact imaging device is sought to be provided. In order to accomplish the above object, an imaging device is formed by lamination of a plurality of layers including: an imaging element layer that has an imaging element part; a lens layer that has a lens part whose distance from the imaging element part is changeable, and is disposed between a subject and the imaging element part; and an actuator layer that has an actuator part to move the lens part, and is disposed between the subject and the imaging element part.01-20-2011
20110026148ACTUATOR ARRAY SHEET - Provided is a technique for achieving both higher functionality and higher precision in a device including a compact drive mechanism. In order to achieve the object, an actuator array sheet comprises a plate-like sheet main body in which a plurality of opening portions penetrating from a front surface to a back surface of the sheet main body are formed in a predetermined arrangement and a first movable unit and a second movable unit protruded from the sheet main body in each of the opening portions, having a displacement element and a support unit for supporting the displacement element.02-03-2011
20110096419LENS DRIVING DEVICE AND CAMERA UNIT - A biasing spring is interposed between a coupling plate and a covering section while being compressed from its natural length. The biasing spring biases, by its resilient force, a lens unit toward a −Z side to bring a surface of the lens unit at the −Z side into contact with an abutment portion of a fixing frame section. When a temperature of an actuator is equal to or lower than a predetermined temperature, a biasing force of the biasing spring surpasses a force generated in the actuator, and thus the lens unit is not moved. When the actuator is heated up to a temperature equal to or higher than the predetermined temperature, the lens unit is continuously moved in the +Z direction. Thereby, movement of a lens due to a change of an environmental temperature can be prevented.04-28-2011
20110199530IMAGING UNIT AND IMAGING DEVICE - A technique of enabling both of higher functionality and higher accuracy in a compact optical system is provided. To achieve this object, an imaging unit has a laminated structure formed by laminating a plurality of layers including: an image capturing element layer including an image capturing element part; a lens layer capable of changing a distance from the image capturing element layer; and an actuator layer including a movable part for moving the lens layer; and a signal transmitter disposed so as to connect the actuator layer and the image capturing element layer, and transmitting a drive signal for driving the movable part from the image capturing element layer side to the actuator layer, and the movable part is deformed according to the drive signal transmitted through the signal transmitter, and the actuator layer is provided between the image capturing element layer and the lens layer.08-18-2011
