20080279542 | Optical Lens Systems - Optical lens attachments and cameras are disclosed. The attachment comprises a coupling mechanism for mating engagement with at least one of a camera and an optical lens. A barrel is coupled at one end to the coupling mechanism. A negative lens unit is coupled to the other end of elongated barrel. A diopter lens is disposed between the barrel and the coupling mechanism. The coupling mechanism, the diopter lens, and the barrel are aligned with an optical axis. Also disclosed is a double swivel optical system, comprising a negative lens unit, a mirror oriented at an angle to the optical axis of the negative lens unit, a roof prism for rotating incident light rays by 90 degrees and inverting an image, a rotation mechanism permitting rotation of the negative lens unit about a vertical axis, an image rotator comprising a prism that can invert an image, the prism disposed within the image rotator, and another rotation mechanism permitting rotation of the roof prism about an optical axis of the image rotator. | 11-13-2008 |
20090060486 | CAMERA BODY, INTERCHANGEABLE LENS, AND CAMERA SYSTEM INCLUDING CAMERA BODY AND INTERCHANGEABLE LENS - An interchangeable lens system includes an interchangeable lens capable of communication between the interchangeable lens and a camera body. The interchangeable lens includes a camera identifying unit that identifies a camera body from information obtained by the communication between the interchangeable lens and the camera body. In response to a data transmitting request instruction transmitted from the camera body through the communication, the camera identifying unit converts reply data into a format adapted for the camera body on the basis of an identifying result of the camera identifying unit, and transmits the reply data. | 03-05-2009 |
20090110381 | FIXING STRUCTURE FOR AN AUXILIARY LENS OF CAMERAS - A means for fixing an auxiliary lens to the outside of the original lens of a camera body includes an annular base, an annular lens mount and an annular abutting base. The inner edge of the base protrudes upwardly to form a wall. The wall protrudes outwards to form a plurality of blocks. The inner edge of the lens mount is provided with a plurality of notches corresponding to the blocks. A first end surface of the abutting base extends to form a plurality of L-shaped elastic arms corresponding to the blocks and notches. The L-shaped elastic arm extends obliquely from the first end surface toward the lens mount. A gap is formed between the L-shaped elastic arm and the abutting base, so that the L-shaped elastic arm can be bent inwardly when compressed. When the camera body is combined with the auxiliary lens by rotation, the blocks pass through the notches to abut and compress the L-shaped elastic arms. At the same time, the L-shaped elastic arms generate a reaction force, thereby enhancing the tightness between the camera body and the auxiliary lens. | 04-30-2009 |
20110097063 | Camera module - There is provided a camera module. The camera module includes a housing accommodating a lens barrel in which a lens is arranged, a close range lens provided in the housing and covering the lens at the time of shooting at close range, and a driving unit driving the close range lens to cover the lens. | 04-28-2011 |
20110142432 | PORTABLE ELECTRONIC DEVICE - A portable electronic device includes a main body defining a receiving cavity therein, a camera module received in the receiving cavity, and a movable moveable lens. The camera module includes a casing and a wide-angle lens unit received in the casing. The movable lens is received in the receiving cavity and spaced a distance from the camera module. The movable lens is movable between a first position where the wide-angle lens unit is covered by and optically aligned with the movable lens, thereby the movable lens and the wide-angle lens unit cooperatively constituting a telephoto lens, and a second position where the wide-angle lens unit is misaligned with the movable lens and exposed to an exterior. | 06-16-2011 |
20110229114 | CAMERA BODY, ACCESSORY, CAMERA SYSTEM, AND INFORMATION REWRITING METHOD - A camera system including a camera body, an interchangeable lens, and an accessory mounted between the camera body and the interchangeable lens, wherein the accessory has a signal processing unit configured to process a signal input into the accessory and a storage unit configured to store information to be used when performing the signal processing, the camera system further including a pseudo interchangeable lens which can be mounted on the accessory instead of the interchangeable lens and which is configured to supply power from the camera body to the accessory when mounted on the camera body via the accessory, and a control unit configured to, while the camera body, the accessory, and the pseudo interchangeable lens are connected, when the accessory receives within a predetermined duration predetermined information, enable communication between the camera body and the accessory even after the predetermined duration has elapsed, and rewrite the information stored in the storage unit. | 09-22-2011 |
20110229115 | CAMERA BODY, INTERCHANGEABLE LENS, ACCESSORY, CAMERA SYSTEM, AND METHOD FOR REWRITING INFORMATION - A camera system includes a camera body, an interchangeable lens, and an accessory to be mounted between the camera body and the interchangeable lens, wherein the accessory includes a signal processing unit configured to process a signal input into the accessory, a storage unit configured to store information used for performing the signal processing, and a blocking unit configured to prevent direct communication from the camera body to the interchangeable lens when the information stored in the storage unit is rewritten via the camera body. | 09-22-2011 |
20120033955 | INTERMEDIATE ACCESSORY FOR CAMERA SYSTEM, AND CAMERA SYSTEM USING THE SAME - An intermediate accessory enables a camera and an exchange lens to communicate with each other through an information processor configured to provide predetermined processing for information received from one of the camera and the exchange lens, and to transmit information that has undergone the predetermined processing, to the other of the camera and the exchange lens, while the camera and the exchange lens are being attached. The intermediate accessory obtains lens identification information from the exchange lens, which is used to identify the exchange lens. The intermediate accessory enables a camera and an exchange lens to communicate with each other without intervening the information processor and transfers to an operation restricting mode used to restrict at least part of an operation the intermediate accessory, when the lens identification information indicates a specific exchange lens that does not require the predetermined processing. | 02-09-2012 |
20120114319 | CAMERA BODY, INTERCHANGEABLE LENS, AND INTERMEDIATE LENS - A camera body is mountable with an intermediate lens which is mountable to an interchangeable lens. The intermediate lens has a first lens and a first drive controller operable to control drive of the first lens. The interchangeable lens has a second lens and a second drive controller operable to control drive of the second lens. The camera body includes an operation unit operable to receive an operation performed by a user, and a body controller operable to control the first drive controller and the second drive controller. The body controller sends a signal for driving the first lens to the first drive controller and/or sends a signal for driving the second lens to the second drive controller, according to the user operation performed on the operation unit. | 05-10-2012 |
