Description

  The present invention relates to a print system including a television apparatus and a printer, and the television apparatus.

  In the field of DTP (Desktop publishing), color profiles of input devices, display devices, and print devices are created by the color management system, and any device can be expressed in the same color by referring to this profile. It is like that. This means that once an input image is correctly mapped to a device-independent color space using a color profile, the device color profile is used to recreate the correct color for that device so that this color is reproduced correctly. Realized by re-mapping. Hereinafter, a device-independent space is referred to as a PCS color space (Profile Connection Space). Examples of the PCS color space include Lab space, XYZ space, CIECAM02 (Commission Internationale de l'Eclairage Color Appearance Model 2002) space, and the like.

  FIG. 4 is a block diagram showing a configuration example of such a DTP system, in which 100 is a scanner as an example of an input device, 110 is a personal computer (PC), 120 is a monitor as an example of a display device, 130 Is a printer as an example of a printing device. The scanner 100 transmits image data obtained by optically reading a document to the PC 100 together with an ICC (International Color Consortium) profile (scnr) for the scanner 100. In the PC 100, the Device> PCS conversion unit 111 converts the image data by mapping the image data in the PCS color space according to the ICC profile (scnr). When the PC 110 displays the image data on the monitor 120, the PCS> Device (mntr) conversion unit 112 converts the image data mapped in the PCS color space according to the ICC profile (mntr) for the monitor 120, and the monitor 120 Output to. Further, when the PC 110 causes the printer 130 to print the image data, the PCS> Device (prtr) conversion unit 113 converts the image data mapped in the PCS color space according to the ICC profile (prtr) for the printer 130, and The data is output to the printer 130.

  Here, the ICC profile (mntr) is determined so that the color mapped in the PCS color space is accurately displayed on the monitor 120, and the ICC profile (prtr) is also the color mapped in the PCS color space. Since it is determined that the image is printed accurately by the printer 130, the monitor 120 and the printer 130 can express the same color.

  However, in the monitor 120, color adjustment is possible to reflect the taste of the viewer by the monitor 120 main body or the graphics card on the PC 110 side, and when such color adjustment is performed on the monitor 120, The content of the color adjustment (color adjustment value) is not reflected on the print image, and an image having a different hue from the image viewed on the monitor 120 is printed and output. Note that the color adjustment of the image by the image editing application installed in the PC 110 or the printing application attached to the printer 130 is reflected at the time of printing on the printer 130, but the color adjustment on the monitor 120 is performed. In this case, the color of the reproduced color is different between the monitor 120 and the printer 130.

  Patent Document 1 discloses a photo print creation system that can reflect a color reproduction region of a photo print created by a photo processing apparatus on a monitor screen. In this system, a photographic processing apparatus including a printer unit that creates a photographic print using image data and a first monitor, and a PC including a second monitor are connected via a network. The processing device creates a photographic print based on the image data acquired by the PC. A printer driver installed in the PC performs print management using a print data setting unit that sets print data, a profile of the printer unit, a profile acquisition unit that acquires a profile of the first monitor, and a color management process using these profiles. Color management means for previewing the color reproduction area of the photographic print on the second monitor.

  In recent years, there has been a demand for a system for printing a captured image or the like with a printer even in a television apparatus. FIG. 5 is a block diagram showing the configuration of a printing system in which a printer is connected to a conventional television apparatus. In the figure, 140 is a conventional television apparatus, and 150 is a printer.

  The television apparatus 140 performs various image processing on the image obtained by receiving the TV broadcast signal, and then outputs the image to a display device exemplified by an LCD (Liquid Crystal Display) module. The module 142 is executing image display. In the television apparatus 140, the color defined based on the broadcast standard of the TV broadcast signal is not necessarily preferred by the viewer. Therefore, in the television apparatus 140, color adjustment can be performed by a manufacturer or a viewer, and the image processing unit 141 performs color adjustment on the image based on the setting value (color adjustment value). As a result, an image is displayed on the screen of the television apparatus 140 in a color adjusted to suit the viewer's preference, such as a preferable skin color, preferable red, blue sky, and green of trees.

  In such a printing system in which the printer 150 is connected to the television apparatus 140, first, a captured image among images obtained by receiving TV broadcast signals is transmitted to the printer 150 as a print image. Subsequently, on the printer 150 side, the print processing unit 151 performs print processing on the print image and outputs the print image to the print module 152, and the print module 152 executes printing.

At this time, it is desirable that the viewer should feel that the printed image is the same as the image viewed on the television device 140. However, when the image displayed on the television device 140 is printed by the printer 150, even if the television device 140 and the printer 150 are adjusted in advance so as to have the same color tone, the television device 140 has a favorite The content of the color adjustment (color adjustment value) is not reflected on the print image, and an image having a color different from the image viewed on the television device 140 is printed and output.
JP 2003-244468 A

  As described above, in a printing system including a television device and a printer, the color that can be expressed by the television device is different from the color that can be expressed by the printer. An image with a different hue from the color-adjusted image that has been viewed is printed and output.

  In view of the fact that color adjustments are often made by manufacturers and users in television devices, it is also conceivable to apply the technique described in Patent Document 1 to television devices in order to solve the above-described problem of hue differences. It is done.

  However, the use of this system requires a large processing capacity and generally requires a PC, which complicates the system and increases the cost. More specifically, it is preferable that the television apparatus 140 be compatible with differences in the manufacturer and model of the printer 150 in order to provide versatility. For this purpose, the PC 110 in the system of FIG. It is necessary to adopt a configuration equivalent to that of the printer 150 or to install a driver suitable for the printer 150. In the latter case, it is necessary to obtain a driver via a network or to provide a drive device for a recording medium such as a CD that is not normally provided in the television device 140. Whichever configuration is adopted, the system configuration becomes complicated and the cost is increased.

That is, in the technique described in the cited document 1, it is necessary to perform color management by obtaining profiles of the first monitor, the second monitor, and the printer unit and displaying them on a PC in order to display colors accurately. However, it is difficult for general users to obtain these data and input to the PC. This is particularly difficult in a system in which a PC is replaced with a television device or a system incorporated in a television device. In addition, although each device is connected via a network, in order to properly operate the devices connected to the network, specialized knowledge of network connection is required, which is also difficult for ordinary people to handle.

  As described above, it is not easy to apply the technique described in Patent Document 1 to a television apparatus, and the configuration is difficult for general users to use.

  The present invention has been made in view of the actual situation as described above, and can be printed with a color that feels the same as the color displayed on the television apparatus with a simple configuration and with a simple operation for a general user. An object of the present invention is to provide a simple print system.

  The fifth technical means is a television apparatus in the print system of any one of the first to fourth technical means.

  According to the printing system of the present invention, it is possible to print with a color that feels the same as the color displayed on the television apparatus with a simple configuration and a simple operation for a general user.

  A print system according to the present invention is a system including a display device that displays an input image, a television set having image processing means, and a printer. The image processing means maps the input image to a display color space (color space for the display device) from the color profile of the input image, the characteristics of the display device, and the color adjustment value set in the television apparatus, Output to the display device.

  As a main feature of the present invention, the television apparatus includes the following profile generation means and transmission means. The profile generation means generates a color profile for printing for printing with a printer, that is, a color profile for printing for appropriately printing an image for printing, in a color equivalent to the color displayed on the display device. . The transmission unit transmits the print image of the input image to be printed by the printer and the print color profile generated by the profile generation unit to the printer. In other words, the television apparatus has a color profile generation (creation) function, and is configured to transmit a print image and a print color profile for appropriately printing the print image to the printer.

  On the other hand, the printer includes the following first conversion means, second conversion means, and printing means.

In addition, since the processing load is reduced in creating an image to be sent to a printer, creating a profile, and necessary image processing, it can be easily installed.

  Hereinafter, a printing system according to the present invention will be described in detail with reference to the drawings, taking each embodiment as an example.

<First Embodiment>
FIG. 1 is a block diagram showing a configuration example of a print system according to the first embodiment of the present invention. In FIG. 1, 10 is a television apparatus, and 20 is a printer.

  The printing system illustrated in FIG. 1 (hereinafter referred to as the present system) includes a television device 10 and a printer 20, and is configured to be able to transmit data from at least the television device 10 to the printer 20 by the transmission means described above. For example, the TV apparatus 10 and the printer 20 are configured by wired connection such as a USB (Universal Serial Bus) cable, an IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 1284 cable, or wirelessly by a wireless communication device. It may be configured by connection. Alternatively, a configuration may be adopted in which both the television device 10 and the printer 20 are equipped with reading devices for various portable recording media, data is written from the television device 10 to the portable recording medium, and the printer 20 reads the data. . Of course, data such as print results may be transmitted from the printer 20 side to the television apparatus 10.

  The television apparatus 10 in the present system includes an image processing unit 11 as an example of an image processing unit, a Device> PCS conversion unit 12, an LCD PCS> Device conversion unit 13, an LCD module 14 as an example of a display device, and a profile. And a color profile generation unit 15 as an example of a generation unit. Further, the printer 20 in this system includes a Device> PCS conversion unit 21 as an example of a first conversion unit, a PCS> Device conversion unit 22 for a printer as an example of a second conversion unit, and a print as an example of a printing unit. And a module 23.

  First, image display on the television device 10 will be described. The main input signal of the TV apparatus 10 is TV broadcast (TV broadcast), and an image obtained by decoding the TV broadcast signal is an input image. Although a color profile is not attached to the current TV broadcast, the color space used in the standard is determined for the TV broadcast, and the color profile of the input image can be determined based on this. In the future, a broadcast with a color profile may be considered, and in such a broadcast, the color profile of the input image can be acquired from the broadcast.

  When an external device such as a recorder or a player (not shown) is connected to the television device 10, an output signal from the external device can be used as an input signal. At this time, the color profile may be obtained from an external device, the color profile may be determined in the television device 10 based on the recommended color space standard for the input signal, or may be input separately by the television device 10. . In addition, a still image from a digital camera or the like may be input to the television device 10. This may be used for a still image accompanied by a color profile. Even when no color profile is attached, there is a recommended color space standard for still images taken with a digital camera, and the color profile can be determined based on this. Further, when an image captured by a digital camera is used as an input image, the color profile may be separately input by the television device 10. Even when the input image is another image, the color profile may be determined or input by some means.

  The image processing unit 11 has a color adjustment function for adjusting to a favorite color, and performs various image processing including color adjustment on the input image. The color adjustment may be intentionally performed by the manufacturer of the television device 10 at the time of shipment, or may be adjusted separately or in addition by the user of the television device 10. In any color adjustment, it is a process of changing the color of the input image.

  This color adjustment processing can be realized by, for example, the following 3 × 3 matrix calculation. The input image signals are R0, G0, B0, and the corrected signals are R1, G1, B1, and are expressed by the following equations.

  Here, M1, M2, M3, M4, M5, M6, M7, M8, and M9 are conversion coefficients. The user or the like performs color adjustment by appropriately selecting this conversion coefficient indirectly while looking at the actual screen, the conversion coefficient (color adjustment value) is stored, and the conversion coefficient can be read out during the actual color adjustment. it can.

  The Device> PCS conversion unit 12 converts the image after such color adjustment into the PCS color space. The PCS color space is a device-independent color space (device-independent color space). For example, an XYZ space, a Lab space, a CIECAM02 space, or the like standardized by the CIE is used. Hereinafter, an example in which an XYZ space is adopted as the PCS color space will be described.

  The Device> PCS conversion unit 12 uses the color profile of the input image for the conversion process. This color profile describes data necessary for conversion processing in the Device> PCS conversion unit 12, and more specifically has the following contents. An input image of the television apparatus 10 is converted into a television standard ITU-R BT. 709, BT. From the 709 standard, a color profile A for converting this signal into the PCS color space can be determined. The main contents include a white point (XYZ value) of the input signal, a γ value, a conversion coefficient from R, G, B to XYZ, and a white point of PCS.

  An example of the conversion process in the Device> PCS conversion unit 12 using the color profile A is as follows. That is, ITU-R BT. The RGB signal 709 has been subjected to non-linear processing, and processing for returning it to a linear signal is performed. More specifically, γ values are used, and inputs are R ′, G ′, B ′ (when the input is after color adjustment, the above-mentioned R1, G1, B1 correspond respectively), and first, Perform conversion.

R = R ′ ^ γ
G = G '^ γ
B = B '^ γ

  Subsequently, the PCS color space is converted into XYZ by 3 × 3 matrix processing as in the following equation. Here, K1, K2, K3, K4, K5, K6, K7, K8, K9 are conversion coefficients from R, G, B to XYZ, and are included in the color profile A described above.

  In this way, the color-adjusted image is converted into the PCS color space. In other words, if the image subjected to the preferred color adjustment is converted by the Device> PCS conversion unit 12 using the color profile of the input image, the image reflecting the preferred color adjustment is mapped into the PCS color space. The

  Further, the above-described equation for conversion from R ′, G ′, B ′ to X, Y, Z can be similarly applied to the case where the desired color adjustment is not performed at all. That is, if the conversion process in the Device> PCS conversion unit 12 is performed using the color profile A on R ′, G ′, B ′ (input images R0, G0, B0), the input image itself is converted to BT. 709 standard color space can be converted to PCS color space.

  The PCS color space image is then converted into a signal for driving the LCD module 14 by the LCD PCS> Device conversion unit 13 and output to the LCD module 14. More specifically, the PCS> Device conversion unit for LCD 13 uses the color profile of the LCD module 14 to display an image in the PCS color space so that the color represented in the PCS color space is correctly displayed on the LCD module 14. Convert. In this manner, the LCD module 14 displays an image reflecting the result of color adjustment in the image processing unit 11.

  Through the above processing, the input image is color-adjusted, and the color reflecting the result is mapped to the PCS color space and converted into a signal for driving the LCD module 14, so that the content of the image in the PCS color space is obtained. Is correctly displayed on the LCD module 14. In general, the Device> PCS conversion unit 12 and the LCD PCS> Device conversion unit 13 are incorporated in the image processing unit 11, and actually, it is not necessary to map the image to the PCS color space, and the LCD module 14 is directly installed. Since these may be converted into signals for driving, these are virtually shown in a dotted frame in FIG.

  Next, print processing in the present embodiment will be described. The television apparatus 10 sends an image to be printed (print image) and a color profile (print color profile) to the printer 20 by the transmission means. The transmission means in this embodiment transmits the input image as it is to the printer 20 as a print image. For example, among the images obtained by decoding the input signal, an image (input image) that has been subjected to image capture processing by a user operation is transmitted as it is to the printer 20 as a print image.

  The transmission unit transmits the print color profile generated by the color profile generation unit 15 together with the input image to the printer 20. The color profile generation unit 15 in the present embodiment uses a PCS color space so that an input image has a color equivalent to the display color on the LCD module 14 (of course, the display color of the image after color adjustment) as a print color profile. Generate a profile for mapping to.

  More specifically, the input image of the television device 10 is converted into the television standard BT. 709. As described above, BT. The color profile A for converting this signal into the PCS color space can be determined from the 709 standard. In this embodiment, the image mapped to the PCS color space when displayed on the LCD module 14 is an image obtained by performing color adjustment processing on the input image as described above. Therefore, the print color profile for mapping the input image of the television apparatus 10 to the PCS color space is BT. The color profile B is obtained by adding the content of desired color adjustment to the color profile A that maps the input image of the 709 standard to the PCS color space.

  As described above, the preferred color adjustment processing can be realized by 3 × 3 matrix calculation. The processing of the color profile A includes 3 × 3 matrix calculation as described above. Using this fact, it is possible to reflect the desired color adjustment processing by changing the conversion coefficient from RGB to XYZ. Therefore, the color profile B as the printing color profile generated by the color profile generation unit 15 may be obtained by appropriately changing the conversion coefficient of the color profile A from RGB to XYZ.

  The printer 20 has a function of mapping a print image based on an input print color profile (here, color profile B), as exemplified by the Device> PCS conversion unit 21 and the printer PCS> Device conversion unit 22. The print module 23 prints it. Next, this process will be specifically described.

  First, the printer 20 receives an input image that is a print image and a color profile B, and the Device> PCS conversion unit 21 uses the color profile B to map the input image to the PCS color space. Here, the input image of the printer 20 is an input image of the television device 10, and the color profile B is a profile for mapping an image obtained by adding a favorite color adjustment to the input image of the television device 10 to the PCS color space. Therefore, the same data as the PCS color space of the television device 10 is mapped to the PCS color space in the printer 20.

  Next, in the printer 20, the printer PCS> Device conversion unit 22 converts the image in the PCS color space into a signal for driving the print module (print device) 23. That is, the printer PCS> Device conversion unit 22 converts the image based on the color profile of the print module 23 so that the color expressed in the PCS color space is correctly printed by the print module 23. Then, the print module 23 prints the converted image.

  Accordingly, the television device 10 correctly displays the color in the PCS color space, the printer 20 correctly prints the color in the PCS color space, and the PCS color space of the television device 10 and the printer 20 is the same data. It becomes the same color as the color of the television apparatus 10.

  In the present embodiment, since the image to be sent to the printer 20 is an input image, special image processing for sending to the printer 20 is not necessary. The print color profile to be sent to the printer 20 is a profile for mapping an image obtained by adding a desired color adjustment to the input image to the PCS color space. As described in the display process, the image is actually displayed in the television device 10. There is no need to map to the PCS color space, as long as a color profile for printing can be created. Therefore, in this embodiment, image processing in the television device 10 can be reduced.

  Further, it is not possible to specify when the user's favorite color adjustment process is performed by the user. The contents of this color adjustment must be reflected in the print color profile sent to the printer 20. Therefore, in this embodiment, when an image is sent to the printer 20, it is necessary to send a print color profile together with the image.

<Second Embodiment>
FIG. 2 is a block diagram showing a configuration example of a print system according to the second embodiment of the present invention, in which 30 is a television device and 40 is a printer. The printing system illustrated in FIG. 2 includes a television device 30 and a printer 40, and is configured to be able to transmit data from at least the television device 30 to the printer 40 as in the system of FIG.

  The television apparatus 30 in the present embodiment includes an image processing unit 31 as an example of an image processing unit, a Device> PCS conversion unit 32, a PCS> Device conversion unit 33 for an LCD, and an LCD module 34 as an example of a display device. And a color profile generation unit 35 as an example of profile generation means. The printer 40 according to this embodiment includes a Device> PCS conversion unit 41 as an example of a first conversion unit, a printer PCS> Device conversion unit 42 as an example of a second conversion unit, and an example of a printing unit. And a print module 43. These parts 31 to 33 and 41 to 43 differ from the parts 11 to 13 and 21 to 23 having the same names in the first embodiment only in the following points.

  This embodiment is different from the first embodiment in that an image (print image) to be sent to the printer 40 is an image after performing a desired color adjustment process. In accordance with this, the color profile for printing sent to the printer 40, that is, the color profile for printing generated by the color profile generation unit 35 also changes.

  That is, the color profile generation unit 35 is equivalent to the display color on the LCD module 34 (of course, the display color of the image after color adjustment), as the print color profile, in which the color adjustment value is reflected in the input image. A profile for mapping to the PCS color space so as to be a color is generated. Then, the transmission unit transmits an image in which the color adjustment value is reflected in the input image to the printer 40 as a print image, and transmits the generated print color profile to the printer 40.

  A color profile for printing that converts an image obtained by performing a favorite color adjustment process on an input image of the television apparatus 30 into a PCS color space so as to be a color equivalent to a display color on the LCD module 34 is the first embodiment. As explained in BT. The color profile A for converting this signal to the PCS color space from the 709 standard may be used. Therefore, BT. For an input image conforming to the 709 standard, the color profile generation unit 35 only needs to generate (actually determine) the color profile A, and the transmission means uses the color profile A used by the Device> PCS conversion unit 32 as it is. 40 may be transmitted. This is because the content of the preferred color adjustment is reflected on the transmitted print image.

  As described above, in this embodiment, the printer image must be generated, but instead, it is not necessary to newly generate a print color profile exclusively for transmission to the printer 40, and it is used in the television device 30. Can also be used as a color profile. Furthermore, since the contents of the preferred color adjustment are reflected in the transmitted print image, the same print color profile transmitted to the printer 40 may be transmitted every time the print image is transmitted. However, it is not necessary to send every print image. For example, when the color profile of the input image is changed by switching the input source to a digital camera or the like, the print color profile may be transmitted.

  Also in the present embodiment, the Device> PCS conversion unit 32 and the LCD PCS> Device conversion unit 33 are normally incorporated in the image processing unit 31, and it is actually necessary to map the image to the PCS color space. However, in FIG. 2, these are virtually represented in a dotted frame because they may be directly converted into signals for driving the LCD module 34. In other words, the print color profile sent to the printer 40 is a profile that maps an image obtained by adding a favorite color adjustment to the input image to the PCS color space so that the color is equivalent to the display color on the LCD module 34. Also in this embodiment, it is not necessary to actually map an image to the PCS color space in the television apparatus 30.

<Third Embodiment>
FIG. 3 is a block diagram showing a configuration example of a print system according to the third embodiment of the present invention, in which 50 is a television apparatus and 60 is a printer. The printing system illustrated in FIG. 3 includes a television device 50 and a printer 60, and is configured to be able to transmit data from at least the television device 50 to the printer 60 as in the system of FIG.

  The television apparatus 50 according to the present embodiment includes an image processing unit 51 as an example of an image processing unit, a Device> PCS conversion unit 52, an LCD PCS> Device conversion unit 53, and an LCD module 54 as an example of a display device. And a color profile generation unit 55 as an example of profile generation means. The printer 60 according to the present embodiment includes a Device> PCS conversion unit 61 as an example of a first conversion unit, a PCS> Device conversion unit 62 for a printer as an example of a second conversion unit, and an example of a printing unit. And a print module 63. These parts 51 to 53 and 61 to 63 differ from the parts 11 to 13 and 21 to 23 having the same names in the first embodiment only in the following points.

  The present embodiment is different from the first embodiment in that an image (print image) to be sent to the printer 60 is an image after mapping into the PCS color space. In accordance with this, the color profile for printing sent to the printer 60, that is, the color profile for printing generated by the color profile generation unit 55 also changes.

  That is, the color profile generation unit 55 only needs to generate a profile having contents indicating that the PCS color space is used as the print color profile. Then, the transmission unit transmits an image obtained by further mapping an image in which the color adjustment value is reflected on the input image to the PCS color space as the print image, and transmits the generated print color profile to the printer 60. Transmit to.

  In the printer 60, since the received print image is already an image in the PCS color space, the Device> PCS conversion unit 61 does not need to perform actual image processing, interprets the received print color profile, and prints the image as it is. May be sent to the printer PCS> Device conversion unit 62 and printed by the print module 63.

  In this embodiment, since an image mapped in the PCS color space is sent, the Device> PCS conversion process in the printer 60 can be reduced. However, in the television device 50, an image actually mapped in the PCS color space must be created. In this embodiment, the color profile for printing transmitted to the printer 60 does not need to be sent for each image, and the same color profile may be transmitted.

  Also in this embodiment, the Device> PCS conversion unit 52 and the LCD PCS> Device conversion unit 53 are usually configured to be incorporated in the image processing unit 51. In the present embodiment, since the image only needs to be mapped to the PCS color space for transmission to the printer 60, the image processing unit 51 directly converts the signal into a signal for driving the LCD module 54 for display. May be output to the LCD module 54.

  As mentioned above, although 1st-3rd embodiment was demonstrated, each embodiment does not compete for superiority and inferiority, but has the characteristics in the location (processing place) which can reduce load. Which one is adopted may be determined based on the balance between the processing contents of the television device and the processing contents of the printer in realizing the system.

  As described above with reference to the embodiments, the print system according to the present invention is configured only by the television apparatus and the printer, and the system configuration is simple. The television apparatus and the printer may be connected to the network, but it is preferable not to adopt the network connection in order to simplify the system configuration. In the printing system according to the present invention, it is not necessary to obtain a color profile and input it later. Therefore, it is possible to realize a system capable of printing with a color that can be easily used by a general user and that is the same color as that seen on a television device.

  In the third embodiment, the television device 50 generates a print color profile and transmits it to the printer 60. However, as another embodiment, the TV device 50 may be configured not to generate and transmit a print color profile. Have the same effect. In this embodiment, a printer dedicated to the PCS color space that prints only image data in the PCS color space may be employed as the printer.
