Abstract
A camera system and method provide a trailing motion blur effect without the use of a flash. In one embodiment, a variable light-transmissive filter is positioned in front of an image sensor. While the light-transmissive property of the filter is lower, the blurred image of the object in motion is produced. The light-transmissive property of the filter is increased during the exposure in order to produce a clearer image of the object. In a method, a plurality of images taken in rapid succession are combined to produce a clear image of the object with a trailing blurred image of the object.
Claims16
A camera system comprising:
- an image sensor;
- at least one lens in front of the image sensor;
- and
- a variable light-transmissive filter in front of the image sensor, the variable light-transmissive filter configured to increase its light-transmissive properties from a non-opaque, light-transmissive initial setting by at least one stop at an end of an exposure of the image sensor.
A camera accessory comprising:
- a shutter configured to be secured to a front of a lens of a camera, the shutter including a variable light-transmissive filter capable of increasing its light-transmissive properties from a non-opaque, light-transmissive initial setting by more than one stop;
- a battery pack configured to be connected to a hot shoe of the camera;
- and
- a cable connecting the battery pack to the shutter.
