Description

Specification

Recording film, recording apparatus and method, and computer program

[0001] The present invention relates to a recording film for preventing illegal recording of a movie screened on a movie theater screen, a recording apparatus and method for recording content such as a movie on such a recording film, and a computer. The present invention relates to the technical field of computer programs that function as such recording devices.

Background art

[0002] Currently, in theaters throughout the country (or around the world), movies are shown by projecting images onto a screen by a projector (or a projector). Here, the problem of illegal recording in which the video displayed on the screen is recorded with a video camera is highlighted. Specifically, a pirated version of a movie has been created by recording and recording the video projected on the screen and the sound flowing from the speakers with a video camera. Especially in the new movie, the problem is closely watched as a problem that may affect the subsequent revenue plan such as DVD sales.

[0003] Various techniques for preventing the creation of such pirated copies have been developed. According to the technology disclosed in Patent Document 1, the infrared light is projected from the infrared lamp onto the entire screen, so that only when the video is illegally recorded by a video camera or the like, the infrared light is projected. Warnings indicated by light are recorded. And since the infrared light is projected, the infrared light is not visually recognized at all by a spectator who is watching a regular movie.

[0004] Patent Document 1: US Pat. No. 6,018,374

Disclosure of the invention

Problems to be solved by the invention

However, with this technology, in order to display a warning or the like, infrared light is projected onto the screen by an infrared lamp separately from the projection of the movie (that is, separately from the movie projector). There is a technical problem that the scale of the equipment is large and labor is required. [0006] The present invention has been made in view of the above-described conventional problems, for example, a recording film that does not require a projection device such as an infrared ray lamp to be provided as a separate special device other than a projector, and the like. It is an object of the present invention to provide a recording apparatus and method for recording content such as a movie on such a recording film, and a computer program that causes a computer to function as such a recording apparatus.

Means for solving the problem

[0007] (Recording film)

In order to solve the above problems, the first recording film of the present invention is a first photosensitive layer on which first recording information is recorded by being exposed to visible light, and non-visible light having a wavelength different from the visible light. And a second photosensitive layer on which the second recording information is recorded.

[0008] According to the first recording film of the present invention, the first photosensitive layer is sensitive to visible light. Accordingly, predetermined first recording information (for example, video information such as a movie as described later in detail) can be recorded by exposing the first photosensitive layer to visible light. On the other hand, the second photosensitive layer is sensitive to non-visible light. Therefore, by exposing the second photosensitive layer to invisible light, predetermined second recording information (for example, as will be described in detail later, letters, numbers, figures, graphic code patterns, etc. Can record messages such as warnings and various information such as copyright information including serial numbers. The “invisible light” in the present invention means light that cannot be detected by human eyes, and specifically means light other than visible light.

When such a recording film is projected onto a screen using a projector or the like, the first recording information recorded on the first photosensitive layer and the second recording information recorded on the second photosensitive layer are on the screen. Projected. At this time, the person who is actually looking at the screen can only see the first recording information recorded on the first photosensitive layer, and cannot see the second recording information recorded on the second photosensitive layer. This is because the second recorded information recorded on the second photosensitive layer is recorded by being exposed to invisible light, and the second recorded information is projected on the screen by invisible light. is there. On the other hand, for example, according to an imaging device such as a video camera described later, not only the first recording information recorded on the first photosensitive layer but also the second recording information recorded on the second photosensitive layer is sensed and imaged (recording). Is done. [0010] Thus, according to the first recording film, a predetermined image is not captured on an image captured by an imaging device such as a video camera, which does not affect a normal audience watching the image projected on the screen. Information can be included (included). Therefore, even if the image projected on the screen using an imaging device is illegally imaged, the pattern shape indicating that the image was illegally imaged (more specifically, a warning message as described later) Therefore, it is very disturbing when viewing the captured video. This leads to stopping the act of illegally capturing the image displayed on the screen in this way, and as a result, it is possible to suitably protect the copyright of the image displayed on the screen. Become.

[0011] Then, in order to record the recorded information on the recording film itself (more specifically, on the second photosensitive layer or the like), an existing projector (especially, irradiating to visible light in addition to visible light) Projector equipped with a lamp capable of recording the information recorded on one recording film can be displayed on the screen. Therefore, the above-mentioned various benefits can be enjoyed at a low cost without requiring a separate special device other than the projector (for example, a dedicated projector such as an infrared lamp). Furthermore, since it has two photosensitive layers, it is possible to record recording information as video information such as a movie and recording information such as a warning text separately, and for recording normal video information. It has the advantage of having no effect. Furthermore, there is an advantage that both video information such as a movie and recording information for protecting the copyright of the movie information can be recorded on one recording film.

As a result of the above, according to the first recording film of the present invention, it is possible to display information such as a warning text without providing a projection device such as an infrared lamp as a separate special device other than the projector. .

[0013] One aspect of the first recording film of the present invention further comprises a filter layer for blocking the visible light between the first photosensitive layer and the second photosensitive layer.

[0014] According to this aspect, visible light is blocked by one filter layer, and infrared light is selectively irradiated to the second photosensitive layer, so that the second photosensitive layer can be exposed to invisible light. Become.

[0015] In another aspect of the first recording film of the present invention, the third recording information is obtained by exposure to other invisible light having a wavelength different from the wavelength of invisible light to which the second photosensitive layer is exposed. Recorded A third photosensitive layer.

[0016] According to this aspect, the second recording information is recorded on the second photosensitive layer by invisible light having one wavelength, while the third photosensitive layer has another wavelength different from the one wavelength. The third record information is recorded by other invisible light. Accordingly, the first recording information recorded on the first photosensitive layer by the recording device having a filter that cuts invisible light having one wavelength is recorded on the second photosensitive layer, and the second recording information is recorded. If it is illegally recorded without including it, it is possible to prevent inconvenience. In other words, even when such a filter is used, the third record information recorded by exposing to invisible light having other wavelengths that cannot be cut by the filter is illegally recorded as the first record. Can be put into information. Therefore, the various benefits described above can be enjoyed more effectively.

In order to solve the above problems, the second recording film of the present invention is sensitive to first recording information recorded by exposure to visible light and invisible light having a wavelength different from the visible light. To record the second record information.

[0018] According to the second recording film of the present invention, predetermined first recording information (for example, video information such as a movie) can be recorded by exposing the recording film to visible light. On the other hand, by exposing the recording film to invisible light, it is possible to record predetermined second recording information that is the same as or different from the first recording information (for example, letters, numbers, figures, etc. as pattern shapes). it can.

When such a recording film is projected onto a screen using a projector or the like, the first recording information and the second recording information are projected on the screen in the same manner as the first recording film described above. However, those who actually look at the screen can only see the first record information and not the second record information. On the other hand, for example, an imaging device such as a video camera described later senses and records (records) not only the first recording information but also the second recording information.

[0020] Thus, according to the second recording film, the recorded information is recorded on the video imaged by the imaging device such as a video camera, which does not affect the normal audience watching the video image displayed on the screen. Can be included (included). As with the first recording film, these recorded information recorded on one recording film can be displayed on the screen by an existing projector. Therefore, separate special equipment other than a projector (e.g. For example, the above-mentioned various benefits can be obtained at a low cost without requiring an infrared projector. In this way, the second recording film can enjoy the same benefits as the various benefits of the first recording film described above.

As a result of the above, according to the second recording film of the present invention, it is possible to display information such as a warning text without providing a projection device such as an infrared lamp as a separate special device other than the projector. .

In one aspect of the second recording film of the present invention, the first recording information and the second recording information are recorded on different recording layers (photosensitive layers).

[0023] According to this aspect, for example, video information such as a movie is used as the first recording information in the first recording layer (first recording layer).

For example, various information for protecting the copyright of the video information can be recorded as second recording information on the second recording layer (second photosensitive layer).

[0024] Furthermore, since it has two recording layers, recording information as video information such as a movie and recording information such as a warning text can be recorded separately, and normal video information It has the advantage of not affecting the record.

[0025] Another aspect of the second recording film of the present invention is a filter layer that blocks the visible light between a recording layer that records the first recording information and a recording layer that records the second recording information. Is further provided.

[0026] According to this aspect, visible light is blocked by the filter layer, and infrared light can be selectively applied to the recording layer on which the second recording information is recorded. As a result, the second recording information is suitable. Can be recorded.

[0027] The second recording film of the present invention is recorded by being exposed to other invisible light having a wavelength different from the wavelength of the invisible light that is exposed when the second recording information is recorded. Third record information is further recorded.

[0028] According to this aspect, the second recording information and the third recording information are recorded by exposing each of a plurality of non-visible lights having a plurality of different wavelengths. Therefore, there is a disadvantage that the first recording information is illegally recorded without including the second recording information by the recording device including the filter that cuts invisible light in the wavelength band used for recording the second recording information. It can be prevented. That is, even when such a filter is used, the The third recorded information recorded by exposure to invisible light in a wavelength band that cannot be recorded can be incorporated into the first recorded information that has been illegally recorded. Therefore, the various benefits described above can be enjoyed more effectively.

[0029] According to another aspect of the first or second recording film of the present invention, the second recording information includes copyright information of the first recording information and warning text information that warns unauthorized use of the first recording information. At least one of the above.

[0030] According to this aspect, it is possible to project a warning sentence and characters indicating the copyright owner of the video. Therefore, a warning or the like can be clearly notified to a person who attempts to record the first record information illegally.

[0031] In another aspect of the first or second recording film of the present invention, the second recording information includes restriction information for restricting at least one of recording and reproduction of the first recording information.

[0032] According to this aspect, if, for example, a recording device or the like is manufactured in conformity with the restriction information standard, the first recording information or the like is illegally recorded when the recording device or the like recognizes the restriction information. Can be forcibly stopped. Alternatively, if the playback device is manufactured in compliance with the restriction information standard, the playback of the first recorded information, etc., that was illegally recorded is forcibly stopped when the playback device recognizes this restriction information. It is also possible to make it. Therefore, such point power can further protect the copyright of the first recorded information and the like.

[0033] According to another aspect of the first or second recording film of the present invention, the second recording information includes reproducible area information indicating an area where the first recording information can be reproduced, and the first recording information. It includes at least one of name information indicating the name of a point to be reproduced (for example, a theater or a movie theater).

[0034] According to this aspect, even when the illegally recorded first record information is put on the market, the origin (for example, in which movie theater was illegally recorded) is appropriately recognized. This has the advantage of making it easier to take countermeasures against subsequent illegal records.

[0035] In another aspect of the first or second recording film of the present invention, the second recording information includes identification information for identifying the recording film.

[0036] According to this aspect, the first record information or the like illegally recorded by referring to the identification information, etc. Power It is possible to preferably recognize which recording film has been recorded. Therefore, there is an advantage that it is easy to take countermeasures against subsequent illegal records.

[0037] In another aspect of the first or second recording film of the present invention, the second recording information includes history information indicating a history relating to recording of the first recording information.

[0038] According to this aspect, by referring to the history information, it is possible to appropriately recognize the first recorded information or the like that has been illegally recorded. Can be. Therefore, it has the advantage that it is easy to take countermeasures against subsequent illegal records.

[0039] In another aspect of the first or second recording film of the present invention, the second recording information includes a bar code pattern.

[0040] According to this aspect, more information can be included in the barcode pattern than when the second recording information or the like is recorded as actual characters. In addition, the recorder can display the second recorded information in a format that can be easily recognized by various devices such as a player.

[0041] In another aspect of the first or second recording film of the present invention, the first recording information includes video information.

[0042] In this aspect, as described above, since the copyright of video information such as a movie can be suitably protected, the first or second recording film is very suitable for recording a movie or the like. The

[0043] In another aspect of the first or second recording film of the present invention, the invisible light includes at least one of infrared light and ultraviolet light.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the best mode for carrying out the present invention will be described in each embodiment in order with reference to the drawings.

[0061] First, with reference to FIG. 1, description will be given on the basic configuration of the embodiment of the recording film of the present invention. FIG. 1 is a plan view and a cross-sectional view conceptually showing the recording film according to this example.

[0062] As shown in FIG. 1 (a), a recording film 100 according to this example is mainly used for movies, and is a film having a width of 16 mm or a film having a width of 35 mm. Or a film with a width of 60 mm. A plurality of frames 105 of a predetermined size are assigned to the recording film 100 so that, for example, 24 frames of video can be recorded for a playback time of approximately one second.

[0063] Fig. 1 (b) shows a II cross-sectional view of the recording film 100 shown in Fig. 1 (a). As shown in FIG. 1 (b), the recording film 100 has a laminated structure composed of a plurality of layers. Specifically, from the upper side of FIG. 1 (b), protective layer 110, blue sensitive emulsion layer 121, yellow filter layer 111, green sensitive emulsion layer 122, intermediate layer 112, red sensitive emulsion layer 123, cyan filter layer 113, An infrared sensitive emulsion layer 124, an antihalation layer (reflection layer) 114, and a film base layer 130 are provided. When an image or the like is recorded on the recording film 100, light (or infrared light) is irradiated from the upper side in FIG.

The protective layer 110 is a layer provided to protect the recording film 100.

[0065] The blue-sensitive emulsion layer 121 is a layer sensitive to blue light, and is used for projecting a blue image after development. More specifically, the blue-sensitive emulsion layer 121 is sensitive to light having a wavelength of about 4 OO nm to about 500 nm.

[0066] The green-sensitive emulsion layer 122 is a layer that is sensitive to green light. Used to project More specifically, the green sensitive emulsion layer 122 is sensitive to light having a wavelength of about 5 OO nm to about 600 nm.

[0067] The red-sensitive emulsion layer 123 is a layer sensitive to red light, and is used to project a red image after development. More specifically, the red-sensitive emulsion layer 123 is sensitive to light having a wavelength of about 6 OO nm to 700 nm.

[0068] The infrared-sensitive emulsion layer 124 is a layer that is sensitive to infrared light, and displays an image that cannot be detected by the human eye after development. More specifically, the infrared sensitive emulsion layer 124 is sensitive to infrared light having a wavelength of approximately 700 nm or more.

[0069] Each photosensitive emulsion layer is a photosensitive material such as a halogenated silver (eg, silver chloride (AgCl) silver iodide (Agl) or silver bromide (AgBr)) or a color former. It contains couplers and protective colloids (eg gelatin) to harden them. However, a coupler (chromagenic dye) as a color former may be added when the recording film 100 is developed. For example, the green-sensitive emulsion layer 122 contains a yellow colored coupler. Alternatively, for example, the blue-sensitive emulsion layer 123 includes a blue colored coupler. The same applies to other sensitive emulsion layers.

[0070] The yellow filter layer 111 has a property of blocking (cutting) blue light (that is, light having a wavelength of approximately 400 nm to 500 nm). The presence of such a yellow filter layer 111 prevents the green light sensitive emulsion layer 122 having the property of being slightly sensitive to blue light from being exposed to blue light. The red-sensitive emulsion layer 123 has the same effect.

The intermediate layer 112 is provided to separate the green sensitive emulsion layer 122 and the red sensitive emulsion layer 123.

[0072] The cyan filter layer 113 has a property of blocking red light (that is, light having a wavelength of approximately 600 nm to 700 nm). The presence of such a cyan filter layer 113 prevents the infrared sensitive emulsion layer 124 from being sensitive to red light.

[0073] The antihalation layer 114 contains silver colloid and black silver, and prevents the incident light of the upper force in FIG. 1 from being irregularly reflected at the boundary with the film base layer 130. As a result, noise or the like due to light that is irregularly reflected on the recording film 100 is not included. Images and the like can be recorded.

[0074] The film base layer 130 is the base (basic) of the entire recording film 130, and includes, for example, polyethylene terephthalate (PET), polyethylene naphthalate, and the like.

Note that the order of the layers shown in FIG. 1 is not limited to this. Blue sensitive emulsion layer 121 is selectively exposed to blue light, green sensitive emulsion layer 122 is selectively exposed to green light, red sensitive emulsion layer 123 is selectively exposed to red light, and red light is selectively exposed. The order of the layers can be arbitrarily set as long as the infrared sensitive emulsion 124 can selectively expose infrared light.

Subsequently, with reference to FIG. 2 and FIG. 3, the operation of recording information by irradiating the recording film 100 according to the present embodiment with light (eg, visible light, infrared light, etc.) will be described. Advance. Here, in particular, the description of the image photosensitive device (that is, one specific example of the recording device according to the present invention) will be described as appropriate. FIG. 2 is an explanatory diagram conceptually showing the flow of operations when recording information on the recording film 100 according to the present embodiment. FIG. 3 is a diagram of the image photosensitive device according to the present embodiment. It is a block diagram which shows a basic composition notionally

[0077] As shown in FIG. 2, the recording film 100 on which no information is recorded (that is, a blank film) is subjected to a photosensitive process in the image photosensitive device 200, and then developed in the developing device 300. It is. That is, when the left side force in FIG. 2 is also sent to the right side, the predetermined information is recorded on the recording film.

The image photosensitive device 200 irradiates the recording film 100 with predetermined light, so that the blue-sensitive emulsion layer 121, the green-sensitive emulsion layer 122, and the red-sensitive emulsion layer 123 of the recording film are subjected to movies and the like. Video or other information as described below (e.g., directly or indirectly to protect copyright information, warning text, and other copyrights of the video). Information or a bar code pattern indicating such information) may be recorded. However, the image and various information recorded in the image photosensitive device 200 are not fixed on the recording film 100 but are fixed (recorded reliably) on the recording film 100 through the current image processing in the developing device 300. is there. A specific configuration example of the image photosensitive device 200 will be described. As shown in FIG. 3, the image photosensitive device 200 includes an LED (Light Emitting Diode) array 201, a diffusing lens 202, a liquid crystal shutter 203, a lens 204, a roller 210, a CPU 220, and a memory 221.

[0080] The LED array 201 is configured to irradiate the recording film 100 with predetermined light (for example, visible light including infrared light, red light, blue light, and green light). . In the LED array 201, a plurality of LEDs are regularly arranged, and the recording film 100 can be irradiated with light uniformly (or without deviation).

[0081] The diffuser lens 202 is a light force emitted from the LED array 201. The light emitted from the LED array 201 is adjusted so as to have a size (for example, range, width, etc.) that matches the size of the liquid crystal shutter 202. Is configured to be capable of spreading (ie, expanding).

[0082] The liquid crystal shutter 203 is arranged so that the light emitted from the LED array 201 is irradiated on the recording film 100 in a desired irradiation pattern according to the video to be recorded on the recording film 100 and various information. Blocks part of the light emitted from the light and selectively transmits the other part.

The lens 204 is configured to narrow the light so that the light irradiated from the LED array 201 is irradiated to a desired comma 105 of the recording film 100.

[0084] The roller 210 sequentially feeds the recording film 100 having a length of about several tens of meters so that a desired image and various desired information are recorded on each frame 105 of the recording film 100. This delivery needs to be appropriately synchronized with the irradiation pattern in the liquid crystal shutter 203. Specifically, the delivery timing (or speed, etc.) is controlled by the operation of the CPU 220.

The CPU 220 controls the entire image photosensitive device 200 by giving an instruction to each component included in the image photosensitive device 200. The entire image photosensitive device 200 is controlled by a predetermined program running on the CPU 220 or based on the logic circuit configuration of the CPU 220.

The memory 221 is used in general data processing in the image photosensitive device 200 such as an area used as an intermediate buffer accompanying the operation of the CPU 220. Memory 221 is video It consists of a ROM area that stores a program for operating the photosensitive device 200, and a RAM area that stores variables required for the intermediate buffer program operation.

[0087] Subsequently, in the developing device 300, a development process, a bleaching process, a fixing process, and a stabilization process are performed roughly. More specifically, development processing is first performed using a paraphenylene diamine amine developing agent (developer) such as CD-3 or CD-4. Thereafter, bleaching (oxidation) is performed using EDTA iron salt or the like, and unnecessary silver atoms are removed from the recording film 100 (in addition, the yellow filter layer 111 and the non-irritation layer 114). After that, fixing processing is performed using ammonium thiosulfate. The bleaching process and the fixing process may be performed simultaneously. Then, in order to prevent residual magenta color couplers to stabilize the recording film 100 during drying and to remove the remaining magenta color couplers for stabilizing the dye, a stable color treatment is performed using formaldehyde or the like. Thereby, a series of processes in the developing device 300 is completed, and the recording film 100 is completed.

Note that the processing in the developing device 300 described above is merely an example, and the processing performed so that video and various types of information are stably recorded on the recording film 100 is performed in the developing device 300 in the present embodiment. This corresponds to the processing performed in.

At this time, the image photosensitive device 200 may be configured to record various information on the recording film 200 only by infrared light. In this case, only the information recorded using the sensitivity by infrared light is recorded on the recording film 100 sent out from the image photosensitive device 200. That is, only the infrared-sensitive emulsion layer 124 is exposed, and the other blue-sensitive emulsion layer 121, green-sensitive emulsion layer 122, and red-sensitive emulsion layer 123 are not exposed. At this time, the LED array 201 irradiates infrared light having a wavelength of, for example, 850 nm. After recording various information on the infrared-sensitive emulsion layer 124, the recording film 100 (specifically, the blue-sensitive emulsion layer 121, the green-sensitive emulsion layer 122, and the red-sensitive layer) is utilized by using other visible light sensitivity. Movies such as movies are recorded in the emulsion layer 123).

[0090] Alternatively, a recording film 100 in which an image such as a movie has already been recorded in the blue-sensitive emulsion layer 121, the green-sensitive emulsion layer 122, and the red-sensitive emulsion layer 123 (ie, the blue-sensitive emulsion layer 121 and the green-sensitive emulsion layer 122). And the recording film 100) in which each of the red-sensitive emulsion layer 123 is exposed In addition, various kinds of information may be additionally recorded using infrared light sensitivity. At this time, the LED array 201 emits infrared light having a wavelength of, for example, 850 nm.

[0091] Alternatively, each of the blue-sensitive emulsion layer 121, the green-sensitive emulsion layer 122, the red-sensitive emulsion layer 123, and the infrared completed emulsion layer 124 is obtained by using both visible light sensitivity and infrared light sensitivity. At the same time, it may be configured to record a video or other information such as a movie. When recording at the same time, the LED array 201 needs to irradiate visible light in addition to 850 nm infrared light. At this time, the LED array 201 that irradiates infrared light and the LED array 201 that irradiates visible light may be provided, or the wavelength of the light emitted by the LED array 201 may be switched appropriately. May be. Alternatively, both the image photosensitive device 200 including the LED array 201 that irradiates infrared light and the image photosensitive device 200 including the LED array 201 that irradiates visible light may be used.

The recording film 100 that has been subjected to such photosensitive processing and development processing will be described with reference to FIG. FIG. 4 is a plan view conceptually showing the appearance of a recording film on which video and various types of information are recorded.

[0093] As shown in FIG. 4, the recording film 100 that has been subjected to the light-sensitive process and the development process is usually subjected to infrared light in addition to the image of a movie or the like to be recorded (for example, a human image). Recorded information (for example, various patterns such as characters, figures or barcode patterns) is recorded! When such a recording film 100 is placed in a movie theater or the like and projected on a screen using a projector, various benefits as described later can be obtained.

Here, the case where the recording film 100 is actually screened in a movie theater or the like will be described with reference to FIG. 5 and FIG. Here, Fig. 5 conceptually shows the state of the screen 400 when the movie is viewed from the audience and the state of the image displayed on the monitor 500 when the movie recorded by the video camera is played back. FIG. 6 is a plan view showing a bar code pattern displayed on the monitor 500 and a table showing the contents of information shown by the bar code pattern.

[0095] When the recording film 100 according to this embodiment is projected on a screen 400 of a movie theater or the like using a projector, the projector lamp needs to emit infrared light in addition to visible light. is there. Therefore, it is necessary to replace the projector lamp with a lamp capable of emitting infrared light. However, even existing lamps already used in projectors emit infrared light to some extent. Therefore, it is not always necessary to replace the lamp! /.

[0096] When the recording film 100 on which the above-mentioned video and various information are recorded is projected on the screen 400 using a projector in a movie theater or the like, the movie displayed on the screen 400 is actually a movie. As shown in Fig. 5 (a), the audience watching in the hall can only see the movie image recorded in the blue-sensitive emulsion layer 121, the green-sensitive emulsion layer 122, and the red-sensitive emulsion layer 123. The various information recorded in the infrared sensitive emulsion layer 124 is not visible! /. Actually, various information recorded in the infrared sensitive emulsion layer 124 is displayed on the screen, but since it cannot be perceived by the human eye, the various information is not visually recognized.

[0097] On the other hand, when a movie displayed on the screen 400 is recorded by, for example, a commercially available video camera or camcorder and played back on the monitor 500 or the like, FIG. As shown, not only the images of movies and the like recorded in the blue-sensitive emulsion layer 121, the green-sensitive emulsion layer 122 and the red-sensitive emulsion layer 122 but also various information recorded in the infrared-sensitive emulsion layer 124 are simultaneously displayed. Played. In other words, various information such as warning text recorded in the infrared sensitive emulsion layer 124 is also visually recognized by a viewer who watches a movie recorded by a video camera or the like in a movie theater by playing it on a monitor 500 or the like. . This is because the CCD (Charge Coupled Device) light sensing range of video cameras, etc., is wider than the human eye and records light other than visible light (for example, infrared light). is there.

[0098] For example, as shown in Fig. 5 (b), "WARNING! CAN'T COPY THIS FIL M !!!! COPYRIGHT 2004 PN Corporation (Warning! Recording prohibited! Copyrighted by PN Corporation) Is displayed on the monitor 500. Such a warning text is displayed in white on the monitor 500, for example.

[0099] In addition to or instead of the warning text, as shown in FIG. 6A, for example, various information (that is, a bar code pattern) is displayed on the infrared sensitive emulsion layer 124 so that a barcode pattern is displayed on the monitor 500. One code pattern) may be recorded. In this case as well, the viewer who is actually watching the movie displayed on the screen 300 in the movie theater, The screen is not visible. On the other hand, when a movie displayed on the screen 400 is recorded by a video camera camcorder or the like and reproduced on the monitor 500 or the like, a barcode pattern is displayed on the monitor 500.

[0100] As shown in FIG. 6 (b), the barcode pattern as shown in FIG. 6 (a) includes various types of information. For example, the copyright of a movie or the like recorded on the recording film 100 is included. Information on the copyright holder indicating the person (or author), area information indicating the region where the movie can be shown (region information), and theater name information indicating the name of the theater where the movie was actually shown In addition, a history of movies and other information recorded on the recording film 100 (for example, the name of the facility where the exposure or development was performed or the date and time when the development or exposure was actually performed) is shown. It includes history information, an identification number for identifying the recording film 100 itself (for example, an identification number for identifying the manufacturing site where the recording film 100 is manufactured), and the like.

Furthermore, the barcode pattern includes recording control information and playback control information (ie, so-called CCI (Copy Control Information)) for controlling recording (recording) and playback (screening) of a movie. Specifically, the recording control information is recorded on the recording film 100 and is used for prohibiting recording of a movie or the like or permitting only certain devices. If the video camera is a video camera that conforms to the standard of recording control information and has a proper license for recording movies, the infrared sensitive emulsion layer can be read by reading the recording control information. It is also possible to configure so that a movie can be properly recorded without being interfered by various information recorded in 124. Alternatively, if the video camera complies with the standard of recording control information, it can be configured to forcibly stop recording a movie when the recording control information is read. The reproduction control information is used for prohibiting reproduction of a movie or the like recorded on the recording film 100 or permitting only certain devices. If the player is a player compliant with the standard of playback control information and has a valid license for playing a recorded movie, the infrared sensitive emulsion layer can be read by reading this playback control information. It is also possible to configure the movie to be properly played back without being interfered by various information recorded in 124. Alternatively, if the player complies with the standard of playback control information, the playback of the recorded movie is forcibly stopped when the playback control information is read. It is also possible to configure.

[0102] For this information, the barcode pattern drawn on the screen 400 (or the monitor 500) is read by a barcode reader or the like (or a barcode reader provided in a recorder or player such as a video camera). In fact, you can get it. For example, by reading the barcode pattern shown in FIG. 6 (a) with a barcode reader, various types of information as shown in FIG. 6 (b) can be actually obtained. That is, the copyright holder of the movie recorded on the recording film 100 is PN Corporation, the playable area is “Japan (Ja pan)”, and the name of the screening theater is “Ginza 1st Theater” (Ginza 1st Theater) ”, and recording of movies, etc. on the recording film 100 was performed on August 10, 2004 at the facility A, and the recording film 100 is PC-F Corporation (PN -F Corporation). In addition, recording control information and playback control information can be obtained as a predetermined data string, for example.

Further, the barcode pattern is not limited to the one-dimensional barcode as shown in FIG. 6 (a), and may be, for example, a two-dimensional barcode or a three-dimensional barcode. Alternatively, as represented by text multiplex broadcasting, a format such as teletext may be used. The information contained in such a bar code pattern is not limited to the specific example shown in FIG. 6 (b), and other various information (especially movies such as movies recorded on the recording film 100). Information that can contribute directly or indirectly to the protection of copyrights). Further, the various types of information shown in FIG. 6 (b) may be drawn as actual characters indicating the various types of information without being drawn as a barcode pattern. Alternatively, a data string, a symbol string, or a pattern shape conforming to a predetermined format may be drawn.

In this way, what information is recorded on the recording film 100 (more specifically, on the infrared-sensitive emulsion layer 124) using infrared light can be arbitrarily set by the user. It is possible. Alternatively, the user may input information according to a predetermined template so that various types of information according to the predetermined template are recorded. In any case, recording is performed on the recording film 100 using various information power infrared light as described above.

[0105] As described above, according to the recording film 100 of the present example, in a movie theater. It is possible to insert (include) various kinds of information such as a predetermined warning text and copyright information into the video recorded by a video camera or the like that does not affect the normal audience watching the movie. Therefore, even if a movie is illegally recorded in a movie theater using a video camera or the like, the video contains a warning text indicating that the video has been illegally recorded. Therefore, the recorded video can be viewed. Very disturbing. This leads to stopping the act of illegally recording the movie in the movie theater as described above, and as a result, the copyright of the movie can be suitably protected.

[0106] In order to record such various kinds of information on the recording film 100 itself, it is projected on a screen using an existing projector (in particular, a projector capable of projecting infrared light in addition to visible light). Can do. At this time, in order to project infrared light, for example, it is sufficient to replace the lamp of the existing projector, etc., it is necessary to use a separate projection device in addition to the existing projector, or to manufacture a new projector. There is no. Therefore, the above-mentioned various benefits can be enjoyed at low cost without requiring a separate special device other than the projector. In addition, since the blue-sensitive emulsion layer 121, the green-sensitive emulsion layer 122, the red-sensitive emulsion layer 123, and the infrared-sensitive emulsion layer 124 have a laminated structure, a single recording film 100 can contain images such as movies. It has the advantage of being able to record both information for protecting copyright. Furthermore, it has two types of sensitive emulsion layers, a sensitive emulsion layer for recording video information such as movies and a completed emulsion layer for recording various information such as warning texts and barcode patterns. Therefore, it is possible to record the recording information as video information of movies and the like and the recording information such as warning texts independently on one recording film, which may affect the recording of normal video information. It has an advantage.

Furthermore, in this embodiment, the warning text is not only recorded on the recording film 100 but also various other copyright information (for example, the history of the author's name, the theater being played, and the recording film 100). Etc.) and CCI. For this reason, even if an illegally recorded movie is put on the market, etc., the source of the movie (eg, in which movie theater was recorded, in which facility the movie was recorded), etc. It can be recognized appropriately, and it becomes easy to take countermeasures against subsequent illegal recording. For example, if it is determined at which facility the information was recorded, it was verified whether the facility had sufficient security management. This makes it easier to testify. For example, if devices such as video cameras are manufactured in conformity with CCI, it is possible to forcibly stop illegal recording of movies when these devices recognize CCI. . If a playback device is manufactured in compliance with CCI, it is possible to forcibly stop the playback of a movie that has been illegally recorded when the playback device recognizes this CCI. Therefore, from this point of view, it is possible to further protect the copyright of the movie.

Furthermore, in this embodiment, these various types of information can be recorded on the recording film 100 as a barcode pattern. For this reason, an information device such as a video camera or an information device such as a player can easily recognize the above-described various information in a format on the screen 400 (or on the monitor 500). Have. By recording various information as a barcode pattern, there is also an advantage that more information can be included compared to drawing various information as normal characters.

[0109] Various information to be recorded on the infrared sensitive emulsion layer 124 may be configured to be recorded on all the frames 105 of the recording film 100, or may be selectively extracted. It may be configured so that recording is performed with respect to the top frame 105.

[0110] When various kinds of information are recorded on some of the frames 105 that are selectively extracted, this is considered in consideration of the light reception timing of a CCD such as a video camera displayed on the screen 400. It is preferable to selectively extract some frames 105. More specifically, a CCD provided in a commercially available video camera or the like records an image at a light reception timing of 30 frames per second when conforming to the NTSC (National TV Standard Committee). In this case, some information should be recorded so that the information is displayed on the S screen 400 continuously for at least twice as long as the light reception timing of the CCD provided in a commercially available video camera or the like. It is preferable to selectively extract the frame 105. In other words, CCD light reception is repeated at a cycle of 1Z30 seconds (about 33 milliseconds)! /, So various information is continuously displayed on the screen 400 for a period of at least 2Z30 seconds (about 66 milliseconds). As described above, it is preferable to selectively extract some frames 105 in which various types of information are to be recorded. Of course, it goes without saying that if the standard to which the video camera conforms changes, the selection range of some frames 105 to record various information will change accordingly. [0111] By recording various information in some frames 105 in this way, at least in one frame of the CCD (more specifically, in any one of two consecutive frames) Various information is included in the whole. Accordingly, it is possible to prevent the inconvenience that all the frames recorded by the video camera or the like are recorded in the infrared sensitive emulsion layer 124 and do not contain various information. If various information is included in the entire frame, if there is no various information in the frame, the original video that does not contain any information can be restored by selectively deleting the portion of the frame. There is also a risk of being done. However, in this embodiment, such inconvenience can be prevented, and thereby the copyright of the movie can be more suitably protected.

[0112] In the above-described embodiments, the description has been made using a configuration in which various information is recorded using the infrared sensitive emulsion layer 124. Of course, the infrared sensitive emulsion layer 124 is not limited to infrared light, but is sensitive to, for example, ultraviolet light. Even a recording film having an ultraviolet-sensitive emulsion layer can receive the above-described various benefits. That is, the above-described various benefits can be enjoyed by recording various kinds of information on the ultraviolet sensitive emulsion layer. Alternatively, the above-described various benefits can be enjoyed even with a recording film having a sensitive emulsion layer sensitive to invisible light. That is, by recording various information in this sensitive emulsion layer, the above-mentioned various benefits can be enjoyed. However, it is more preferable to provide a sensitive emulsion layer that is sensitive to invisible light having a wavelength in a range that can be sensed by a CCD provided in a video camera or the like. For example, assuming that CCD 1S can detect light having a wavelength from 300 nm to 900 nm, the recording film 100 has a sensitive emulsion layer that is not visible light but sensitive to invisible light having a wavelength from 300 nm to 900 nm. It is preferable to have such information, and it is preferable that the above-mentioned various information is recorded on such a sensitive emulsion layer.

[0113] Next, with reference to FIG. 7, a description will be given of a modification of the recording film according to the present example. FIG. 7 is a cross-sectional view of a recording film according to a modification.

[0114] As shown in FIG. 7, the recording film 101 according to the modified example is similar to the recording film described above, from the upper side of FIG. 7, from the upper side of FIG. 7, the protective layer 110, the blue-sensitive emulsion layer 121, the yellow filter layer 111, the green color Emulsion layer 122, intermediate layer 112, red-sensitive emulsion layer 123, cyan filter layer 113, infrared-sensitive emulsion layer 124 antihalation layer (reflection layer) 114 and film base layer 130 Yes.

[0115] The recording film 101 according to the modification particularly includes an ultraviolet-sensitive emulsion layer 125 and an intermediate layer 115.

[0116] The ultraviolet-sensitive emulsion layer 125 is a layer that is sensitive to ultraviolet light, and displays an image that cannot be detected by the human eye after development. More specifically, the ultraviolet sensitive emulsion layer 125 is sensitive to ultraviolet light having a wavelength of approximately 400 nm or less.

[0117] The intermediate layer 115 is provided to separate the ultraviolet-sensitive emulsion layer 125 and the infrared-sensitive emulsion layer 124 from each other.

[0118] In the modified example, the above-described various information is recorded in the infrared-sensitive emulsion layer 124 and the ultraviolet-sensitive emulsion layer 125, respectively, on the recording film 101. That is, various information is recorded in the infrared sensitive emulsion layer 124 by irradiating infrared light from the LED array 201, and various information is recorded in the ultraviolet sensitive emulsion layer 125 by irradiating the LED array 201 with ultraviolet light. . At this time, various information may be recorded in each of the infrared-sensitive emulsion layer 124 and the ultraviolet-sensitive emulsion layer 125 in the same frame 105 of the recording film 101. Alternatively, various information is recorded in the infrared sensitive emulsion layer 124 in one frame 105 of the recording film 101, and various information is recorded in the ultraviolet sensitive emulsion layer 125 in other frames 105 other than the one frame 105. You may do it. Alternatively, various information may be recorded in both the infrared-sensitive emulsion layer 124 and the ultraviolet-sensitive emulsion layer 125, and the frame 105 may exist.

[0119] If the recording film 101 on which various kinds of information are recorded in this manner is projected on the screen 400 using a projector in a movie theater or the like, the screen 400 can be seen by both infrared light and ultraviolet light. Various information is projected. Therefore, it is possible to prevent the inconvenience that a movie is recorded in a state that does not include various information by a video camera using a filter that cuts light of a predetermined wavelength band. For example, assume that an unauthorized user is recording a movie with a video camera using a filter that cuts infrared light. At this time, according to the recording film 101 according to the modification, various kinds of information are displayed on the screen by the ultraviolet light in addition to the infrared light. Thus, even if various information displayed on the screen 400 by the infrared light is cut by the filter that cuts infrared light, the various information displayed on the screen 400 by the ultraviolet light is not cut. Therefore, to ultraviolet light Various information displayed on the screen 300 is included in the movie recorded by the video camera. For this reason, as described above, it is possible to better protect the copyright of the movie.

[0120] Further, in addition to providing two types of sensitive emulsion layers sensitive to different invisible light as described above, the third (or more more sensitive to different invisible light). ) Sensitivity You may comprise so that an emulsion layer may be provided. As a result, it becomes more difficult to cut these various types of information by the filter, and the copyright of the movie can be more suitably protected. In addition, even if it does not necessarily include a plurality of sensitive emulsion layers that are sensitive to different invisible light, for example, it may be configured to include a plurality of sensitive emulsion layers that are sensitive to the same invisible light in different wavelength bands. . For example, even a recording film having an infrared sensitive emulsion layer sensitive to 850 nm infrared light and an infrared sensitive emulsion layer sensitive to 880 nm infrared light can enjoy the various benefits described above. is there.

[0121] Further, in the above-described embodiment, the point of preventing illegal recording of a movie projected on the screen 400 has been described in detail. However, the present invention is not limited to the movie, and is not limited to the screen 400. It goes without saying that the copyrights of various contents shown on the screen can naturally be protected.

[0122] The application of the recording film 100 according to the present embodiment is not limited to a movie film as long as it is projected to project some video film using a projector or the like. For example, a slide film or a normal film is used. It can also be applied to photographic films.

[0123] The present invention is not limited to the above-described embodiments, but can be appropriately modified within the scope of the claims and the entire specification without departing from the gist or philosophy of the invention that can be read. A recording film, a recording apparatus and method, and a computer program for recording control are also included in the technical scope of the present invention. Industrial applicability

[0124] A recording film, a recording apparatus and method, and a computer program according to the present invention include, for example, a recording film for preventing illegal recording of a movie screened on a movie theater screen, and a movie on such a recording film. It can be used in a recording apparatus and method for recording content such as Also, for example, various computer equipment for consumer use or business use It can also be used in a recording device or the like that is mounted on or connected to various computer devices.
