Abstract
Abstract A camera device for a photographer viewing a scene to be photographed includes an illumination source for illuminating the scene and means for linearly scanning the scene with said illumination source to provide a visible linear indication of a scanned region of the scene. Control means vary the brightness of the illumination in accordance with changes in one or more scene parameters, to ensure constant visibility of the linear indication.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
75 words
A camera device for a photographer viewing a scene to be photographed comprising an illumination source for illuminating the scene, and means for linearly scanning the scene with said illumination source to provide a visible linear indication of a scanned region of the scene, is characterized by: control means for automatically varying the brightness of the illumination in accordance with changes in one or more scene parameters, to ensure constant visibility of the linear indication.
Claim 2
Dependent Claim
75 words
A camera device for a photographer viewing a scene to be photographed comprising an illumination source for illuminating the scene, and means for linearly scanning the scene with said illumination source to provide a visible linear indication of a scanned region of the scene, is characterized by: control means for automatically varying the brightness of the illumination in accordance with changes in one or more scene parameters, to ensure constant visibility of the linear indication.
Claim 3
Dependent Claim
17 words
The camera device of claim 1, wherein said one or more scene parameters include a camera-to-scene distance.
Claim 4
Dependent Claim
19 words
The camera device of claim 2, wherein the brightness of the illumination is increased as the camera-to-scene distance increases.
Claim 5
Dependent Claim
18 words
The camera device of claim 1, wherein said one or more scene parameters include the ambient light level.
Claim 6
Dependent Claim
20 words
The camera device of claim 4, wherein the brightness of the illumination is increased as the ambient scene light increases.
Claim 7
Dependent Claim
35 words
The camera device of claim 1 wherein said control means varies the brightness of the illumination by varying a scan rate of said scanning means in accordance with changes in one or more scene parameters.
Claim 8
Dependent Claim
103 words
A camera device for a photographer viewing a scene to be photographed comprising an illumination source for illuminating at least a portion of a perimeter of the scene, and means for linearly scanning the illuminated portion of the perimeter to provide a visible frame of at least a portion of the scene, is characterized by: control means connected to said illumination source for automatically varying the brightness of the illumination of at least a portion of the perimeter in accordance with changes in one or more scene parameters, to ensure constant visibility of the frame of at least a portion of the scene.
Claim 9
Dependent Claim
103 words
A camera device for a photographer viewing a scene to be photographed comprising an illumination source for illuminating at least a portion of a perimeter of the scene, and means for linearly scanning the illuminated portion of the perimeter to provide a visible frame of at least a portion of the scene, is characterized by: control means connected to said illumination source for automatically varying the brightness of the illumination of at least a portion of the perimeter in accordance with changes in one or more scene parameters, to ensure constant visibility of the frame of at least a portion of the scene.
Claim 10
Independent Claim
68 words
A method for providing a visible linear indication in a scene to be photographed, comprising the steps of: illuminating the scene; linearly scanning the scene with said illumination source to provide a visible linear indication of a scanned region of the scene; and automatically varying the brightness of the illumination in accordance with changes in one or more scene parameters, to ensure constant visibility of the linear indication.
Claim 11
Independent Claim
68 words
A method for providing a visible linear indication in a scene to be photographed, comprising the steps of: illuminating the scene; linearly scanning the scene with said illumination source to provide a visible linear indication of a scanned region of the scene; and automatically varying the brightness of the illumination in accordance with changes in one or more scene parameters, to ensure constant visibility of the linear indication.
Claim 12
Dependent Claim
