46results about How to "Increase shutter speed" patented technology

Problems, such as unevenness of exposure, caused by the difference in speed between a first curtain and a second curtain and a positional shift between the curtains (the occurrence of an edge darkening phenomenon) can be prevented. In addition, power consumption is reduced. When the shutter speed is set to be low by exposure control means, the exposure start operation is performed using an electronic focal plane shutter function of an image sensor (an electronic focal plane shutter is used for the first curtain), and an exposure end operation is performed by a mechanical focal plane shutter. In contrast, when the shutter speed is set to be high by the exposure control means, the exposure start operation and the exposure end operation are performed using the mechanical focal plane shutter (the mechanical focal plane shutter is used for the first curtain).

The invention relates to a shutter for an optical imaging system, e.g. a digital camera. The shutter comprises an interface between a transparent body and a capillary space. Light rays introduced to the active area of the interface are reflected by total internal reflection when the capillary space is filled with a gas. The light rays are transmitted through the interface when the capillary space is rapidly filled with a liquid. Thus, the light rays are either absorbed or reflected towards an image sensor, depending on the state of the shutter. The liquid is delivered to the capillary space through at least one duct which is positioned opposite the active area.

In order to halt smear sweep-out in a case where the effects of smear charge are considered minor, it is determined whether the shutter is a high-speed shutter when a shutter-release button is pressed. If the shutter is not the high-speed shutter, a CCD is exposed and signal charge accumulates in the photodiodes of the CCD. Smear charge is swept out before the signal charge is shifted from the photodiodes to vertical transfer lines. The signal charge is thenceforth transferred to the vertical transfer lines and a video signal is output from the CCD. In the case of the high-speed shutter, smear sweep-out is halted and charge is shifted from the photodiodes to the vertical transfer lines.
