Orienting projector
摘要:
A film projector for use with frames of processed photographic film having frame-associated image orientation data. The film projector has a light source that emits a collimated beam and a film holder that is disposed to hold individual frames of film in the beam. The film holder is pivotable between a first and second orthogonal orientations. An optical projection system receives the beam from the film holder. The optical system propagates and focuses at least a portion of the beam on a viewing plane external to the projector. A sensor is disposed to read the frame-associated image orientation data. The sensor produces a signal responsive to the image configuration information. A controller receives the signal from the sensor. A repositioner is connected to the film holder. The repositioner is operatively connected to the controller to move the film holder between the orientations responsive to the controller.
