| Number | Title | Issue Date |
| 7333725 | Method and apparatus for metadata synchronization A method and apparatus provides for accurately synchronizing a plurality of sensors, as well as for providing accurate timing information (e.g. timing metadata) associated with the synchronized data capture. According to one aspect of the invention, an apparatus inc... | 02/19/2008 |
| 6490416 | Focal plane shutter having synchronous contact member A focal plane shutter for a camera has a synchronous contact member that produces less chattering than conventional synchronous contact members. One end of an opening electromagnet and one end of a closing electromagnet are separately connected to the hig... | 12/03/2002 |
| 5659819 | Apparatus for taking pictures against white backgrounds An automatic photography apparatus has an object illuminating mechanism that has a high illumination mode and a low illumination mode. A switching control system is provided so that when the apparatus is used to photograph white background documents the i... | 08/19/1997 |
| 4959680 | Camera system A camera system of the type having a lens shutter, a focal-plane shutter, an aperture defined by the lens shutter, and a camera lens, includes a selector circuit which sets an operation mode to either a lens shutter mode in which the lens shutter is opera... | 09/25/1990 |
| 4761666 | Camera capable of flash photography In a camera having a focal plane shutter, a magnet restrains the rearward shutter curtain in response to the supply of power to the magnet.
