Abstract
Abstract An apparatus and method for showing motion in a single color photograph in which motion of an object is shown by displaced images of the object in different colors. The scene to be photographed is illuminated by a light source including a plurality of light units emitting light of differing spectral composition. The light units are individually and sequentially activated, the light emitted from all of the units appearing to be emitted from substantially the same location. The flashing of the light units is controlled by a timer. The resulting photograph shows the non-moving objects in a color which is the composite of the spectral composition of all of the light units, typically the natural color. The movement of an object is shown by a spaced series of sharp images of that object in a variety of colors. The color sequence corresponds to the sequence of the flashes of the light units.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
81 words
Apparatus for color photography of a scene including a moving subject comprising, in combination, a camera having film capable of differentiating between components of a spectrum, a light source for illuminating the subject comprising a plurality of individual light units each adapted to emit a light flash primarily in a distinct portion of said spectrum, and a flash interval control connected to each of said individual light units and adapted to actuate said individual light units successively after predetermined time intervals.
Claim 2
Dependent Claim
81 words
Apparatus for color photography of a scene including a moving subject comprising, in combination, a camera having film capable of differentiating between components of a spectrum, a light source for illuminating the subject comprising a plurality of individual light units each adapted to emit a light flash primarily in a distinct portion of said spectrum, and a flash interval control connected to each of said individual light units and adapted to actuate said individual light units successively after predetermined time intervals.
Claim 3
Dependent Claim
45 words
The apparatus of claim 1, in which the light source includes light conductor means adapted to receive light from each of said individual light units and to project the light from all of said units on to the subject from substantially the same apparent location.
Claim 4
Dependent Claim
16 words
The apparatus of claim 2, in which the light conductor means comprises a fiber optical bundle.
Claim 5
Dependent Claim
31 words
The apparatus of claim 1 wherein each of said individual light units is adapted to produce a flash of short duration in comparison with the speed of motion of said subject.
Claim 6
Dependent Claim
30 words
The apparatus of claim 1 wherein each light unit comprises means to produce a flash and a filter to limit the light therefrom to said distinct portion of said spectrum.
Claim 7
Dependent Claim
63 words
The apparatus of claim 1 in which the camera has a shutter, and the flash interval control comprises a clock timer and clock divider, a synchronizer activated by the shutter to gate impulses from the clock timer and clock divider, and a delay unit for each light unit adapted to count the gated impulses and energize the light unit after a predetermined delay.
Claim 8
Independent Claim
159 words
A method for showing motion of objects in a single photograph taken by a camera focused on the moving objects comprising the steps of providing a light source capable of emitting at least two colors of light; providing a timer connected to said light source for sequentially emitting each of said at least two colors of light; emitting said at least two colors of light in a flashing fashion from said light source, all of said at least two colors of light not flashing at the same time and any two successive flashes of light being flashes of the different colors; opening a shutter of said camera for a period of time in excess of the time period for a single flash of light from said light source; whereby the resulting photograph shows the motion of an object in various sequentially displayed colors corresponding to a sequence of said flashed colors of said at least two colors of light.
Claim 9
Independent Claim
159 words
A method for showing motion of objects in a single photograph taken by a camera focused on the moving objects comprising the steps of providing a light source capable of emitting at least two colors of light; providing a timer connected to said light source for sequentially emitting each of said at least two colors of light; emitting said at least two colors of light in a flashing fashion from said light source, all of said at least two colors of light not flashing at the same time and any two successive flashes of light being flashes of the different colors; opening a shutter of said camera for a period of time in excess of the time period for a single flash of light from said light source; whereby the resulting photograph shows the motion of an object in various sequentially displayed colors corresponding to a sequence of said flashed colors of said at least two colors of light.
Claim 10
Dependent Claim
53 words
The method for showing motion in a single photograph of claim 7 wherein said light source is capable of emitting light from substantially the same apparent location and comprises a number of individual light units, the light from said light units being fed through a fiber optic bundle to the object being photographed.
Claim 11
Dependent Claim
33 words
The method for showing motion in a single photograph in claim 7 wherein said light source is capable of emitting light from substantially the same apparent location and comprises a light mixing chamber.
Claim 12
Dependent Claim
44 words
The method for showing motion in a single photograph of claim 7, wherein said timer is adjustable for changing a time interval between successive flashes of said at least two colors of light in order to show motion of objects moving at different speeds.
Claim 13
Independent Claim
168 words
A method for showing motion of objects in a single photograph taken by a camera having a shutter focused on the moving objects comprising the steps of providing a light source capable of emitting at least two different hues of the same color of light; providing a timer connected to said light source for sequentially emitting flash colors each of said two hues of the same color of light; emitting said at least two hues of the same color in a flashing fashion from said light source while said shutter is open, said at least two hues not flashing at the same time and any two successive flashes being flashes of different hues; opening the shutter of said camera for a period of time in excess of the time period for a single flash of light from said light source; whereby the resulting photograph shows a motion of an object in various sequentially displayed colors corresponding to a sequence of said flashed colors of said colors of light.
Claim 14
Independent Claim
168 words
A method for showing motion of objects in a single photograph taken by a camera having a shutter focused on the moving objects comprising the steps of providing a light source capable of emitting at least two different hues of the same color of light; providing a timer connected to said light source for sequentially emitting flash colors each of said two hues of the same color of light; emitting said at least two hues of the same color in a flashing fashion from said light source while said shutter is open, said at least two hues not flashing at the same time and any two successive flashes being flashes of different hues; opening the shutter of said camera for a period of time in excess of the time period for a single flash of light from said light source; whereby the resulting photograph shows a motion of an object in various sequentially displayed colors corresponding to a sequence of said flashed colors of said colors of light.
Claim 15
Dependent Claim
53 words
The method for showing motion in a single photograph of claim 11, wherein said light source is capable of emitting light from substantially the same apparent location and comprises a number of individual light-emitting units, the light from said light-emitting units being fed through a fiber optic bundle to the object being photographed.
