Title:
CAMERA SHUTTER SYSTEM
Document Type and Number:
WIPO Patent Application WO2001069314
Kind Code:
B1
Abstract:
The camera of the invention includes an improved shutter system that has the same shutter waveform when a flash is employer and when a flash is not employed. In a preferred embodiment, the shutter system includes a shutter that is rotatably mounted to the camera and a shutter opening over which the shutter blade is disposed. A slidable plate in which a first aperture and a second aperture are disposed is coupled to the camera, so that the first aperture is disposed between the first shutter opening and the lens of the camera prior to taking a picture with the camera. The first aperture is preferabyl smaller than the second aperture. When a picture is taken, the shutter blade moves to uncover the shutter opening, and when the shutter opening is uncovered the shutter blade causes the slidable palte to slide with respect to the shutter opening so that the second larger aperture is disposed between the shutter opening and the camera lens. If a flash is used while taking a picture, the flash illuminates while the second aperture is disposed over the shutter opening. The shutter blade then returns to cover the shutter opening. As the shutter blade returns to cover the shutter opening, the shutter blade causes the slidable plate to move, so that the first aperture is disposed over the shutter opening.
