Rotary shutter device |
摘要 |
A rotary shutter device for use in an electronic still camera or a VTR camera has an XY-addressable solid-state imaging device for converting an optical image read by successive horizontal scanning into a video signal, a shutter blade disposed in front of the solid-state imaging device and rotatable about its own axis, the shutter blade having at least one opening for transmitting light therethrough onto the photodetector surface of the solid-state imaging device, and an adjusting blade disposed adjacent to the shutter blade for varying the opening angle of the opening. The shutter and adjusting blades are rotatable together in a direction to successively expose the solid-state imaging device to incident light in the direction in which the solid-state imaging device is vertically scanned. The scanning of the solid-state imaging device for one field is completed between two successive exposures thereof through the opening in the shutter blade.
