Title:
SOFT-FOCUS PHOTOGRAPHING SYSTEM
Document Type and Number:
Japanese Patent JP2007072132
Kind Code:
A
Abstract:
To ensure soft-focus photographing in a simple photographing mechanism.
A photographing mode switching plate 45 has a zone plate part 45a. When a switch ring 47 rotates, the photographing mode switching plate 45 allows the zone plate part 45a to move between a position on the optical axis of an photographing lens 5 and a position out of the optical path of the photographing lens 5 by an interlocking pin 47b. The zone plate part 45a diffracts the object light to impart a soft-focus effect to draw a soft contour to the object image. The exposure time is extended when the zone plate part 45a is on the optical path, so as to compensate the insufficient quantity of the object light blocked by the zone plate part 45a.
