Description




TECHNICAL FIELD OF THE INVENTION




This invention relates in general to the development of film and more particularly to a system and method of digital film development using visible light.




BACKGROUND OF THE INVENTION




During conventional chemical film processing, several different solutions are normally applied throughout the development process in order to produce a negative. Developer is applied to expose film to convert exposed silver halides into elemental silver. The by-product of this reaction reacts with couplers in order to create color dyes within the film. The reaction is stopped by a stopping solution. Any unreacted silver halides and the elemental silver present in the film layers is washed out of the film. The completed negative includes separate emulsion layers composed of color dyes.




Conventional scanner systems generally digitize film using visible light to detect and measure the colors associated with the color dyes in the negative. Conventional scanner systems require that the silver halide and elemental silver particles be washed from the film. The elemental silver particles will block, or occlude, the light and cause speckling used to detect and measure the dye clouds in the negative.




In digital film development, after the application of developer, the developing film is scanned at certain time intervals using infrared light so as not to fog the developing film. Color is derived from the silver latent image detected during development by taking advantage of the milkish opacity of the elemental silver to optically separate the individual layers. Once separate optical data is identified for each layer of emulsion, optical data associated with each layer of blue, green, and red emulsion is used to digitally create a color image.




Conventional digital film processing systems utilize infrared light in order to avoid fogging the film as it develops. In particular, each layer of the developing film remains photosensitive to visible light during the digital film process. The film is not substantially photosensitive to infrared light, which allows the silver latent image to be scanned at multiple development intervals.




One advantage usually associated with digital film development is the ability to develop film using a single application of developer. Digital film development does not require, for example, the stop, fix, clear, wash, wetting agent, and dry processing steps, nor the additional developer or other chemical solutions, used in chemical film processing. As digital film development primarily uses infrared light to detect the level of exposure of silver halides, the presence of elemental silver during such processing may inhibit accurate detection of images represented on the blue, green, and red layers of film emulsion similar to other defects such as scratches and other abnormalities. This problem may be particularly pronounced in detecting latent images held in the green layer of the film emulsion that is generally more difficult to discern relative to latent images held in the upper blue layer and lower red layer of film emulsion.




SUMMARY OF THE INVENTION




In accordance with the present invention, a system and method for digital film development using visible light is provided that substantially eliminates or reduces disadvantages and problems associated with previously developed systems and methods. In particular, the system and method for digital film development using visible light allows for the reduction of disadvantages during film processing that are associated with the presence of elemental silver.




In one embodiment of the present invention, a system for the development of a film is provided that includes an infrared light source and a visible light source. The system also includes at least one sensor operable to collect a first set of optical data from light associated with the infrared light source and a second set of optical data from light associated with the visible light source. The system further includes a processor in communication with the at least one sensor, the processor operable to determine an image on the film in response to the first and second sets of optical data.




In a second embodiment of the present invention, a method of digital film development is presented that includes comparing a first set of optical data collected during a transmission of infrared light through a film with a second set of optical data collected during a transmission of visible light through the film.




Technical advantages of the present invention include providing a system and method for digital film development using visible light that reduces disadvantages and problems associated with previously developed systems and methods. In particular, various embodiments of the present invention allow undesirable data introduced by the presence of elemental silver to be removed or filtered. Additionally, various embodiments of the present invention present higher quality digital images by eliminating defects caused by the presence of elemental silver. A further advantage of various embodiments of the present invention is that more detailed image production is accomplished without the need for additional developers or other chemical solutions.




Other technical advantages will be readily apparent to one skilled in the art from the following figures, description, and claims.

DETAILED DESCRIPTION OF THE INVENTION





FIGS. 1 through 7

illustrate various embodiments of a system and process for enhancing the digital development of film utilizing data collected during the exposure of the film to visible light and infrared light. By utilizing visible light during the development process, a digital image is produced that is compared to data collected during the exposure of the film to infrared light. Such a comparison compensates for the presence of elemental silver during the collection of data using infrared light. In particular, following the collection of data during exposure of film to infrared light, additional data is collected during exposure of the film to visible light. The visible light data is then filtered using the infrared light data in order to produce a final digital image that does not include defects introduced by elemental silver. Various embodiments of the described invention also introduce additional processes of data collection and the filtering of such collected data in order to achieve further improvements in image quality during the digital development of film.





FIG. 1

illustrates one embodiment of a digital film processing system


10


that utilizes both infrared and visible light in detecting a latent image on exposed and developing film such as a film


20


. System


10


includes an infrared light source


30


, a visible light source


40


, and a sensor


50


coupled to a processing computer


60


. In the illustrated embodiment, sensor


50


is positioned on the opposite side of film


20


from infrared light source


30


and visible light source


40


.




In the illustrated embodiment, film


20


includes multiple layers of emulsion such as a blue layer


22


, a green layer


24


, and a red layer


26


. Alternatively, film


20


may include any number of layers corresponding to differences in image characteristics specific to each of the layers. For example, film


20


may include layers specific to different colors or speeds, a particular grain size, or any other suitable distinguishing characteristics.




In the illustrated embodiment, infrared light source


30


is a linear array of light emitting diodes (LEDs) used in combination with a suitable lens for focusing infrared light; however, infrared light source


30


may be any combination of one or more sources of infrared light in any suitable combination such that a desired portion or lateral width of film


20


, hereafter referred to as a segment of film


20


, is illuminated by light originating from infrared light source


30


. For example, infrared light source


30


may be a linear array of LEDs assembled in combination with one or more amplifiers and wave guides such that a predetermined lateral width of film


20


is illuminated at a desired intensity. Infrared light source


30


may be suitably positioned and oriented relative to film


20


and sensor


50


depending on film type and processing conditions. In one embodiment, infrared light source


30


is a reflectometer such as an ellipsometer.




In the illustrated embodiment, visible light source


40


is a tri-linear array of light emitting diodes (LEDs) used in combination with suitable lens for focusing visible light; however, visible light source


40


may be any combination of one or more sources of visible light in any suitable combination such that a segment of film


20


is illuminated by light originating from visible light source


40


. For example, visible light source


40


may be a tri-linear array of red-green-blue LEDs assembled in combination with one or more wave guides such that a predetermined lateral width of film


20


is illuminated at a desired intensity. Visible light source


40


may be suitably positioned and oriented relative to film


20


and sensor


50


depending on film type and processing conditions. In one embodiment, visible light source


40


is a reflectometer such as an ellipsometer. Various embodiments of digital film processing system


10


may incorporate visible light source


40


and infrared light source


30


in a single device. For example, a broadband light source produces both infrared and visible light that can be sensed individually.




Different colors of light interact differently with the film


20


. Visible light interacts with the dyes and silver within the film


20


. Whereas, infrared light interacts with the silver, but the dye dyes are generally transparent to infrared light. The term “color” is used to generally describe specific frequency bands of electromagnetic radiation, including visible and non-visible light. Visible light, as used herein, means electromagnetic radiation having a frequency or frequency band generally within the electromagnetic spectrum of near infrared light (>700 nm) to near ultraviolet light (<400 nm). Visible light can be separated into specific bandwidths. For example, the color red is generally associated with light within a frequency band of approximately 600 nm to 700 nm, the color green is generally associated with light within a frequency band of approximately 500 nm to 600 nm, and the color blue is generally associated with light within a frequency band of approximately 400 nm to 500 nm. Near infrared light is generally associated with radiation within a frequency band of approximately 700 nm to 1500 nm. Although specific colors and frequency bands are described herein, the film


210


may be scanned with other suitable colors and frequency ranges without departing from the spirit and scope of the invention.




In the illustrated embodiment, sensor


50


is a linear sensor and includes at least one lens; however, sensor


50


may be any other sensor suitable for focusing light formed by the reflection or transmission of infrared and/or visible light from or through film


20


. Sensor


50


may include one or more sensing portions suitable for detecting the phase and intensity of one or more wavelengths of light. Sensor


50


may be integrated with infrared light source


30


or visible light source


40


in, for example, a reflectometer such as an ellipsometer.




Processing computer


60


is a personal computing platform and includes a processor


62


and a memory


64


; however, processing computer


60


may be a microcontroller, an application specific integrated circuit, or any other processing device suitable to process data detected by sensor


50


in order to construct, process, and generate a final digital representation of an image captured on film


20


. Processing computer


60


may be coupled to other computers and/or digital film processing stations via a communications network. Processor


62


is a central processing unit and memory


64


includes both random-access memory and read-only memory; however, any suitable processor and memory in any combination may be utilized as processor


62


and memory


64


. In one embodiment, processing computer


60


is integrated into system


10


as a single system, such as an ASIC processor.




In operation, system


10


uses sensor


50


to collect data from film


20


. In one embodiment, system


10


collects data from film


20


at a single development time. Infrared light source


30


emits infrared light during the development of film


20


at a suitable intensity and duration in order to detect the presence of silver grains in film


20


. Sensor


50


detects the portion of such emitted infrared light that is transmitted through film


20


using, for example, a lens to focus such light from a suitable portion of film


20


in order to collect optical data to distinguish optical characteristics of such infrared light.




After data is collected during the transmission of infrared light through film


20


, visible light from visible light source


40


is transmitted through film


20


to detect and measure the light associated with the individual dye clouds in the film


20


. In one embodiment, optical data collected during infrared scanning may be processed to indicate the optimal time for the emission of visible light. In any case, visible light source


40


emits visible light at a suitable intensity and for a suitable duration for transmission through layers


22


,


24


, and


26


of film


20


and detection by sensor


50


. Unlike infrared light, exposure to visible light will cause the remaining silver halide in the film to react, exposing film


20


, and destroying the image stored on the film. Optical data collected by sensor


50


as the result of exposure of film


20


to visible light source


40


may be filtered by processing computer


60


using optical data collected during exposure of film


20


to infrared light source


30


. Such processing allows for the correction of erroneous optical data introduced by the presence of elemental silver during earlier infrared scans. Such correction and image enhancement is further described in U.S. Pat. No. 5,266,805, entitled “System and Method for Image Recovery” and issued to Edgar, which is hereby incorporated herein by reference.




In short, the infrared light detects the location and size of the silver grains within film


20


. The location and size of the silver grains form a defect map that can be used to correct the optical data produced from the visible light. Accordingly, the combination of infrared light source


30


and visible light source


40


may be used to create two different sets of optical data representative of the image fixed on film


20


, which are then processed in combination to remove any imperfections in the final processed digital image caused by the presence of the elemental silver particles. The final processed digital image may then be stored as an image file by processor


62


in memory


64


.




Although

FIG. 1

illustrates a single infrared light source


30


and visible light source


40


located directly across from a single sensor


50


, multiple light sources


30


and


40


may be utilized with multiple sensors


50


. In particular, and referring now to

FIG. 3

, a roll or other array of frames of film


20


may be processed using a film dispensing device


100


that holds film


20


between two or more rollers, sprockets, gears, or other suitable fixtures, applies a suitable developer to film


20


and utilizes a suitable advance mechanism to advance the film frame-by-frame along a processing path


110


. Path


110


causes film


20


to be routed through any suitable number of film processing stations


130


.




In the embodiment illustrated in

FIG. 2

, multiple film processing stations


130


are utilized to detect infrared light transmitted through or reflected from film


20


using one or more infrared light sources


30


and one or more sensors


50


. A following film processing station


130


or group of film processing stations are utilized to detect visible light and/or infrared light transmitted through or reflected by film


20


using one or more light sources


30


and


40


and one or more sensors


50


. Each of film processing stations may be coupled to one or more processing computers


60


. Film processing stations


130


may be used to process particular frames of film


20


in an assembly-line like process whereby frames move consecutively along path


110


at indicated speeds and with suitable pauses such that particular film processing stations


130


adequately process images held on such frames of film


20


.





FIG. 3

illustrates another embodiment of digital film processing system


10


using multiple infrared light sources


30


and visible light source


40


. In particular, one of infrared light sources


30




a


and visible light source


40


are positioned and oriented as illustrated in

FIG. 1

on the opposite side of film


20


from sensor


50


. However, two additional infrared light sources


30




b


and


30




c


are positioned on the same side of film


20


as sensor


50


. Infrared light sources


30




b


and


30




c


are positioned and oriented in such a manner as to allow infrared light emitted to illuminate blue layer


22


of film


20


and reflect off of blue layer


22


such that reflecting light may be detected by sensor


50


and processed by processing computer


60


.




In one embodiment, infrared light from infrared light sources


30




b


and


30




c


is emitted at a particular intensity and duration after the application of a developer to the exterior of blue layer


22


. Infrared light reflecting off of blue layer


22


is then collected by sensor


50


. Next, infrared light source


30




a


is used to transmit infrared light through all layers


22


,


24


, and


26


of film


20


so that light passing through film


20


may be detected by sensor


50


. Finally, visible light source


40


is used as described in

FIG. 1

to collect data on the dye clouds of the film


20


.




The embodiment illustrated in

FIG. 3

has the advantage of being able to collect image data for blue layer


22


independently of green layer


24


and red layer


26


. By collecting optical data from blue layer


22


individually, such blue layer data may be filtered or divided out, by processing computer


60


, from optical data obtained via the through scan performed by transmitting infrared light through all of layers


22


,


24


, and


26


. As optical data from green layer


24


and red layer


26


is usually more difficult to distinguish than optical data from blue layer


22


, improved processing of image data associated with such layers


24


and


26


will result once data from blue layer


22


is eliminated from consideration. Such an advantage of distinguishing data from blue layer


22


also allows an easier determination of when to begin the interval during which visible light is emitted by visible light source


40


. Such a determination is easier because now such determination may focus on the optimal time for image data included only within green layer


24


and red layer


26


.




As described with reference to

FIG. 1

, the embodiment illustrated in

FIG. 3

may be implemented by processing film


20


along path


110


using film dispensing device


100


as illustrated in FIG.

. Again, one or more film processing stations


130


may be utilized to perform the collection of optical data for blue layer


22


using infrared light sources


30




b


and


30




c


and one or more sensors


50


. A second group of one or more film processing stations


130


may be used to perform the through scan of the transmission of infrared light through film


20


using one or more infrared light sources


30




a


and one or more sensors


50


. A third group of one or more film processing stations


130


may then be utilized to detect visible light transmitted through film


20


using one or more visible light sources


40


and one or more sensors


50


.





FIG. 4

illustrates yet another embodiment of digital film processing system


10


used to process film


20


. In the embodiment illustrated in

FIG. 3

, infrared light sources


30


and visible light sources


40


are used in combination with multiple sensors


50


in order to more accurately detect a latent image stored within film


20


. In digital film processing system


10


, two infrared light sources


30


are positioned on either side of film


20


, one sensor


50


is positioned on either side of film


20


, and two visible light sources


40


are positioned on the side of film


20


most proximate to red layer


26


. In particular, infrared light sources


30




b


and


30




c


are again positioned and oriented in such a manner as to allow infrared light emitted to illuminate blue layer


22


of film


20


and reflect off of blue layer


22


such that reflecting light may be detected by sensor


50




a


and processed by processing computer

and processing by processing computer


60


.




In operation, infrared light from infrared light sources


30




b


and


30




c


is emitted at a certain interval after the application of a developer to the exterior of blue layer


22


. Infrared light reflecting off of blue layer


22


is then collected by sensor


50




a.


Then, infrared light sources


30




a


and


30




d


emit infrared light to the exterior of red layer


26


. Infrared light reflecting off of red layer

Next, infrared light sources


30




a


and

, and


26


of film


20


so that light passing through film


20


may be detected by sensor


50




a.


Finally, visible light sources


40


are used as described in

FIG. 1

to collect data on the dye clouds on the film


20


. The embodiment illustrated in

FIG. 4

has the advantage of being able to collect image data from blue layer


22


and red layer


26


independently of each other and green layer


24


. By collecting optical data individually from blue layer


22


and red layer


26


, such blue layer data and red layer data may be filtered or enhanced, by processing computer


60


, using optical data obtained via a through scan performed by transmitting infrared light through all of layers


22


,


24


, and


26


. As optical data from green layer


24


is usually the most difficult to distinguish, improved processing of image data associated with such layer


24


and will result once data from blue layer


22


and red layer

is eliminated from consideration. Such an advantage of distinguishing data from blue layer

collected from the reflection of infrared light as described in steps

may be used for filtering or otherwise to create final image data. In step
