Latest Patents

Nakamura's latest inventions include a **Flash Photographic Exposure Control System** and a **Flash Lighting Unit for a Camera**. The Flash Photographic Exposure Control System is designed to improve exposure control for both daylight and flash photography. This system adeptly adjusts the diaphragm aperture based on camera-to-subject distance, allowing for variations that ensure optimal exposure across differing scenarios. In one embodiment, both the diaphragm value and integrated flash light intensities are increased in tandem with distance, maximizing effectiveness at twice the fixed diaphragm distance. Alternatively, the invention provides mechanisms for increasing these parameters sequentially to maintain consistent exposure quality.

Additionally, the Flash Lighting Unit for a Camera incorporates advanced voltage detecting means within the flash lamp firing circuit. This technology assures that a camera operates within the correct flash exposure range by verifying that sufficient voltage is available to ignite the lamp before the shutter is released. The design includes two transistorized circuits that facilitate this detection and ensure instant feedback to the photographer via a visible light-emitting diode, indicating when the storage capacitor has reached the necessary voltage.
