Abstract

Abstract A film image reader/scanner apparatus providing two capabilities, operable only at separate times wherein one capability provides for the projection onto a viewing screen (60) of a light image created from a film image presented to the apparatus, with the second capability providing for a line-by-line scan of the light image that is directed to a linear scan array (90) for the production of signals representative of the light image.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 148 words
Apparatus having two capabilities operable at separate times wherein one of the capabilities is a light image projection capability that provides for projection to a viewing screen (60) via a light path of the light image created from an image carried on a film when presented to the apparatus, the apparatus including a linear scan array (90) operable to produce signals representative of a light image presented to it; and light directing means (70) positionable with respect to the light path provided for the light image projection capability for progressive presentment of the light image to said linear scan array so said linear scan array receives the full dimension of the light image along a line in one direction whereby the second capability of the apparatus provides for the creation of signals on a line-by-line basis of the image carried on a film when presented to the apparatus.
Claim 2
Dependent Claim 148 words
Apparatus having two capabilities operable at separate times wherein one of the capabilities is a light image projection capability that provides for projection to a viewing screen (60) via a light path of the light image created from an image carried on a film when presented to the apparatus, the apparatus including a linear scan array (90) operable to produce signals representative of a light image presented to it; and light directing means (70) positionable with respect to the light path provided for the light image projection capability for progressive presentment of the light image to said linear scan array so said linear scan array receives the full dimension of the light image along a line in one direction whereby the second capability of the apparatus provides for the creation of signals on a line-by-line basis of the image carried on a film when presented to the apparatus.
Claim 3
Dependent Claim 23 words
The apparatus according to claim 1 wherein said light directing means includes a mirror (70) operable for movement about an axis of rotation.
Claim 4
Dependent Claim 74 words
The apparatus according to claim 1 wherein said light directing means includes a mirror (50) that is movable to a position out of the light path when the apparatus provides the second capability to cause the light images to be directed to said linear scan array and said linear scan array is movable relative to the light image directed to said linear scan array when said mirror is moved out of the light path.
Claim 5
Dependent Claim 25 words
The apparatus according to claim 1 wherein said linear scan array (90) is provided by a series of linearly positioned charge coupled devices or photodiodes.
