Description

  The present invention relates to an image processing apparatus that takes in image data generated by photographing an image and performs a predetermined process, and more particularly, to processing of a photographing date and time when the image is photographed.

  2. Description of the Related Art Conventionally, there is a need to correct a shooting date and time attached to image data when image data shot at a shooting location with a time difference is edited and printed at a later date. For example, when an image taken overseas is printed at a later date without correcting the internal time of the digital still camera, the print time is attached to the print image based on the internal time of the digital still camera. Considering the influence of the time difference overseas, various techniques for correcting the shooting date and time to the local time at the shooting location are being studied.

  For example, Japanese Patent Application Laid-Open No. 2004-151867 discloses a technique for acquiring processing information for processing date / time information in addition to date / time information attached to captured image data, and printing an image by adding a shooting time at a shooting location. It is disclosed. According to such image data processing technology, when printing a captured image, the time difference of the shooting location is input as processing information, and the date and time information attached to the image data is corrected using the time difference. Thus, the shooting time of the shooting location can be easily added to the print image.

JP 2002-135560 A JP 2000-187088 A

  However, the image data processing technique has a problem that the date information correction operation performed at the stage of printing a captured image is complicated. In other words, in order to correct the shooting date with such a technique, the user has to input the time difference of the shooting location. The user has to check the content of the image to be printed one by one, check the time difference of the shooting location, and input it, and the correction to the date of the shooting location is complicated.

  In order to solve such a problem, a method of automatically changing the internal clock of an imaging device such as a digital still camera for each moved position (location) and storing the local time as it is in the captured image data itself. However, when editing multiple images, for example, when arranging multiple images in the order of shooting, it is not preferable to change the internal clock itself because the shooting date and time may be used. .

  The present invention provides an image processing apparatus capable of adding and outputting a captured local time to an image without complicated operations in consideration of such a problem that the operation for correcting the date of shooting is complicated. The purpose is to do.

  In view of the above problems, the image processing apparatus of the present invention employs the following technique. That is, an image processing apparatus that captures image data generated by capturing an image and outputs the image, and is associated with the image data and has a geographical location with respect to the capturing position of the image that is set using wireless communication. Using the associated information input means for inputting the general information and the shooting date and time information based on the standard time, and the correspondence table indicating the time difference from the standard time corresponding to the predetermined position, A time difference is obtained from the geographical information of the image, and the input shooting date and time is corrected to the local date and time of the shooting location where the image was shot, and the corrected shooting date and time is added to the captured image data. And an output means for outputting the output.

  An image processing method corresponding to the image processing apparatus of the present invention is an image processing method for capturing image data generated by photographing an image and outputting the image. Input a geographical information about the shooting position of the image set by using and information of shooting date and time based on the standard time, and a correspondence table showing a time difference from the standard time corresponding to a predetermined position The time difference is obtained from geographical information about the input shooting position, the input shooting date and time is corrected to the local date and time of the shooting location where the image was shot, and the corrected shooting date and time is captured. The gist is to add it to the image data and output it.

  According to the image processing apparatus and the image processing method of the present invention, the geographical information about the shooting position associated with the image data and the shooting date / time information based on the standard time are input, and the position information is obtained from the predetermined correspondence table. Find the time difference with respect to the standard time of the shooting location. Using the obtained time difference, the shooting date and time based on the standard time is corrected to the local date and time of the shooting location, and this is output. By inputting the accompanying information accompanying the image data, the local date and time can be easily added to the image and output. For example, the local date and time can be output without a troublesome operation such as the user editing the shooting date and time.

  The wireless communication of the image processing apparatus having the above configuration is GPS communication, the geographical information about the shooting position includes the longitude and latitude of the place where the image was shot, and the shooting date and time information is the shooting date and time of the shooting. The date and time may be based on Greenwich Mean Time.

  The accompanying information obtained by such GPS communication can be easily added to the image data according to an existing standard such as the Exif format. By complying with these existing standards, a highly versatile image processing apparatus can be constructed.

  The correspondence table of the image processing apparatus having the above configuration is formed based on a time zone representing a time difference from the standard time of a place specified by longitude and latitude, and includes a storage unit that stores the correspondence table, The date correction means may include a reading means for reading the correspondence table from the storage means. In addition, the correspondence table may be configured with detailed time difference data around a specific location.

  According to such an image processing apparatus, the correspondence table is configured based on the time zone. Furthermore, detailed time difference data is provided only around a specific location. By setting a specific location in advance and providing detailed data only in the vicinity thereof, it is possible to reduce the capacity of the data in the correspondence table as compared to the case of providing detailed data of countries around the world as the correspondence table.

  The output unit of the image processing apparatus having the above-described configuration may be a unit that prints the corrected shooting date and time superimposed on the captured image data. As an aspect of the output, by printing the corrected shooting date and time on the image data, it is possible to simplify the user operation in printing the shot image and improve user convenience.

  The present invention can also be implemented as a computer program and a medium recording the computer program. As the recording medium, various computer-readable media such as a flexible disk, a CD-ROM, a DVD-ROM / RAM, a magneto-optical disk, a memory card, and a hard disk can be used.

A. Configuration of image processing device:
FIG. 1 is an explanatory diagram showing an image processing apparatus 100 as an embodiment of the present invention. As shown in the figure, the image processing apparatus 100 captures a predetermined image to be processed, inputs a digital still camera 61 storing the image, and an image stored in the digital still camera 61, and performs a predetermined process. A personal computer 30 (hereinafter referred to as PC 30), a display 43 for displaying an image processed by the PC 30, a keyboard 41 and a mouse 42 as a user interface, a printer 50 for outputting an image processed by the PC 30, and the like. ing.

  The digital still camera 61 includes a CCD as an image sensor, an image processing circuit that performs predetermined image processing on image data captured via the CCD, a memory card 62 that stores image data, and the like, and the digital still camera 61 itself. It has an internal clock that measures the internal time, and a GPS function that stores position information (geographical position information) of the digital still camera 61 using GPS (Global Positioning Systems) communication as one aspect of wireless communication. ing.

  The digital still camera 61 includes a connection port for connecting to the PC 30 with a predetermined cable. Image data stored in the digital still camera 61 is taken into the PC 30 and predetermined image processing is performed based on a user instruction. Is given.

  In place of directly acquiring image data from the digital still camera 61, a recording medium on which captured image data is recorded, such as a memory card 62, a DVD-ROM / RAM 63, and a hard disk 64, is connected to the PC 30; Image data may be acquired from a recording medium.

  The PC 30 includes a CPU 31, a ROM 32, a RAM 33, a hard disk 34, an I / F circuit unit 35, and the like, and each device is connected by an internal bus. The I / F circuit unit 35 is connected to the digital still camera 61, the display 43, the keyboard 41, the mouse 42, and the printer 50, and functions as an interface between the external device and the PC 30.

  A predetermined operation system is stored in the ROM 32, and when the PC 30 is turned on, the CPU 31 reads and starts the operation system OS in the ROM 32.

  The hard disk 34 is installed with various application programs that operate on the operation system, such as a print processing program that captures an image from the digital still camera 61 and generates printing data, and a shooting date correction processing program that will be described later. Yes. The CPU 31 receives an instruction of a user operation via the keyboard 41 or the mouse 42, reads out such a program, develops it on the RAM 33, and executes it.

  The printer 50 is an ink jet printer that can print a color image with four color dots of C (cyan), M (magenta), Y (yellow), and K (black). The printer 50 includes a carriage (not shown) having a plurality of nozzles for ejecting four colors of ink, and feeds the paper in a direction orthogonal to the main scanning direction while reciprocating the carriage (main scanning) ( In the sub-scanning process, ink dots are formed on the paper. Piezoelectric elements, which are piezoelectric elements, are used for ink ejection, and a print image that accurately reproduces the image to be printed is output by controlling the voltage to the piezoelectric element as well as main scanning and sub-scanning. Can do.

  In the image processing apparatus 100 having the above hardware configuration, when the user desires to print a predetermined image in the digital still camera 61, the print processing program is activated via the keyboard 41 and the mouse. This print processing program is a program corresponding to the printer 50, and generates print data corresponding to the print resolution of the printer 50 and the like.

  When the print processing program is started, the CPU 31 reads an image in the digital still camera 61 and displays it on the display 43. The user selects an image to be printed on the display 43 and sets predetermined conditions regarding printing, such as printing conditions.

  After setting these predetermined conditions, upon receiving a print execution instruction by a user operation, the CPU 31 outputs the set print conditions and the print target image to the printer driver. The printer driver is a program module that converts input image data into print data. In the printer driver, the size of the image is changed according to the selected paper size, and each color dot is turned on / off. Generate OFF data (print data). The generated print data is output to the printer 50, and a predetermined print image is output. Note that, on the printed image output in this way, the shooting date and time when the image is captured is printed superimposed on the image.

  In the present embodiment, as part of such a print processing program, a shooting date correction process program for correcting the shooting date and time of an image to be printed shot by the digital still camera 61 is provided. In the shooting date and time correction processing, the additional date and time added to the image data of the image shot by the digital still camera 61 is used to set the shooting date and time printed on the print image, not the date and time based on the internal clock. Process to correct the local date and time at the location (local). In other words, images taken overseas are corrected to the local date and printed.

  In general, various data at the time of shooting is added to image data shot by an imaging device such as a digital still camera. FIG. 2 is an explanatory diagram illustrating an example of a data structure of image data captured by the digital still camera 61. The data structure of the image handled by the digital still camera 61 is a so-called Exif format. Based on the image data in the JPEG format, predetermined image additional information such as shooting information when shooting the image data, thumbnail images, etc. Embedded in a format that conforms to

  The shooting information, which is one of the image additional information, stores various information such as shooting date / time TC by the internal clock of the digital still camera 61, exposure time, aperture value, shutter speed, ISO sensitivity, white balance at the time of shooting. ing.

  Furthermore, the image data in the present embodiment includes GPS information as one of the image additional information. This GPS information includes position information such as latitude, longitude, altitude, etc. using GPS communication, and shooting time and date information based on Coordinated Universal Time UTC (approximately the same as Greenwich Mean Time GMT). Yes. That is, in the digital still camera 61, in addition to the captured image data and the shooting date / time TC based on the internal clock, the GPS position information expressed by the latitude and longitude of the shooting location and the Coordinated Universal Time UTC by GPS are used as a reference. The image data is configured in a format including shooting time and date information (hereinafter referred to as GPS shooting date and time TG).

  In the shooting date / time correction process, the GPS information of the image data is used to correct the GPS shooting date / time TG to the local date / time at the shooting location. The corrected shooting date and time is printed in a form displayed at a predetermined position of the print image as described above. The shooting date / time correction process will be described below.

  In this embodiment, a four-color inkjet printer is used. For example, a six-color inkjet printer, another inkjet printer (for example, Bubble Jet (registered trademark)), a thermal transfer printer, a sublimation type, and the like. Various types of printers such as a printer, a laser printer, or a multifunction machine may be used.

B. Shooting date correction processing:
FIG. 3 is a flowchart of the shooting date correction process. This process is a part of the print processing program, and is executed by the CPU 31 of the PC 30 after the user selects an image to be printed and sets print conditions and the like.

  When the process is started, the CPU 31 acquires position information from the image data of the image selected as the print target (step S300). Specifically, the longitude and latitude of the place where the image was taken are acquired.

  The CPU 31 obtains a time difference from the Greenwich Mean Time GMT of the shooting location where the image data to be printed is generated from the acquired longitude and latitude (step S310). That is, the time zone of the shooting location where the image was shot is recognized.

  The image processing apparatus 100 according to the present embodiment stores a table (conversion table) in which a place expressed by longitude and latitude is associated with a time difference based on Greenwich Mean Time GMT on the hard disk 34. The CPU 31 reads the conversion table from the hard disk 34 and refers to this to recognize the time zone of the shooting location where the image was shot from the position information including longitude and latitude.

  FIG. 5 is an explanatory diagram showing an example of a time zone set for each region. As shown in the figure, each country in the world sets the standard time of each country using a time difference (within ± 12 hours) from Greenwich Mean Time GMT. Generally, an area set to the same time difference is called a time zone. The time zone is basically set at a time difference of every hour in increments of 15 °, but in reality, it is set in a complicated form for each region, each border, and the like.

  In the present embodiment, a conversion table for obtaining a time difference from longitude and latitude (positional information) is set based on the time zone of about 15 ° shown in FIG. In particular, with respect to a specific place set in advance such as a major city, a major country, or a major tourist spot, detailed time difference data corresponding to the position information is provided. In other words, the conversion table includes time difference data in a two-layer structure corresponding to the position information, and after acquiring the first layer time difference data corresponding to the location expressed by the longitude and latitude acquired by the CPU 31, further details are provided. If there is correct data, the time difference data of the second layer is acquired. By providing the conversion table in such a format, it is possible to set a time difference with relatively high accuracy with a small amount of data compared to the case where all the data of the time zone is provided.

  In this way, the CPU 31 that has recognized the time zone of the shooting location from the position information acquires the shooting date and time TG by GPS from the image data of the image selected as the print target (step S320). Note that the shooting date / time TG acquired here is not the shooting date / time TC based on the internal clock of the digital still camera 61 but the shooting date / time based on GPS time and date information.

  The CPU 31 calculates and outputs the shooting date and time (local time) at the shooting location from the acquired GPS shooting date and time TG and the time difference in the recognized time zone (step S330), and ends the series of processing. For example, when it is recognized from the position information that the time difference of the shooting location is -5 hours (GMT-5), the time obtained by subtracting 5 hours from the shooting date and time TG (Coordinated Universal Time UTC) by GPS is used as the local time. It is output and printed at the corner of the printed image.

  The above is the flow of the basic shooting date / time correction process, and the image processing apparatus 100 of the present embodiment can further set various shooting date / time settings. FIG. 4 is an explanatory diagram showing an aspect of a graphical user interface (GUI) in the print processing program.

  When the user activates the print processing program, the PC 30 inputs image data from the digital still camera 61 and displays a GUI screen shown in the figure on the display 43. The plurality of captured images G1 to Gn are displayed in a thumbnail format according to the order of shooting. A scroll bar SB is provided in the vicinity of the thumbnail-displayed image. By moving the scroll bar SB using the mouse 42, an image that could not be displayed on the display 43 can be displayed.

  Two tabs (an “image editing” tab and a “photographing date” tab) are prepared next to the thumbnail image display portion. When the user clicks the “shooting date” tag with the mouse 42, a page displaying detailed setting items related to the shooting date is opened. The “Image Edit” tab is used to make various settings related to printing, such as selecting an image to be printed, setting the paper size, setting the number of copies, and image processing such as trimming. Since the relevance is low, detailed description is omitted here.

  On the page of the “shooting date” tab, a display portion H that displays the shooting date and time of an image to be printed, a check box Cb1 that selects whether or not to print the shooting date and time, and a check that selects automatic summer time setting A box Cb2, a selection portion S for selecting a time zone setting method, and the like are displayed. The display portion H displays the calculation result obtained by performing the above-described shooting date correction processing on the image selected as the print target (for example, the image G4), that is, the shooting date and time at the local time of the shooting location. .

  A check symbol is attached to the check box Cb1 in the default state, and the shooting date and time in the local time displayed on the display portion H is set to be printed together with the image. By removing the check symbol in the check box Cb1 by operating the mouse 42, it is possible to not print the shooting date and time. The check box Cb2 is also marked with a check symbol in the default state, and is set to display the shooting date and time at the local time calculated in consideration of summer time on the display portion H.

  In the time zone selection portion S, a combo box B1 for instructing a time zone setting method, a box B2 for inputting a time difference numerically, and a combo box B3 for selecting a time zone from predetermined options are displayed.

  When the user clicks the button of the combo box B1 with the mouse 42, three types of drop-down lists of “automatic” mode, “user setting” mode, and “fixed” mode are displayed. These are options for setting the time zone, and the “automatic” mode is selected in the default state. That is, when the setting in the combo box B1 is not particularly changed (in the “automatic” mode), the image to be printed is selected and the above-described shooting date / time correction process is executed so that the shooting date / time in the local time is set. Displayed on the display portion H.

  When the user selects the “user setting” mode, the user can input the box B2 for inputting the time difference or the combo box B3. When the user operates the button of the box B2 or the like to directly input the time difference from the Greenwich Mean Time GMT, the display date / time displays the shooting date / time corrected by the GPS shooting date / time TG using the time difference input by the user. Is done.

  When the user clicks the button of the combo box B3 with the mouse 42, a plurality of drop-down lists indicating time zone names are displayed. When the user sets a time zone by selecting one from the list, the shooting date / time corrected by the GPS shooting date / time TG is displayed on the display portion H based on the time zone.

  That is, in the “user setting” mode, position information by GPS is not used to correct the shooting date and time TG. The numerical value input in box B2 and the name of the time zone selected in combo box B3 are linked to each other. For example, when the name of the time zone is selected, the time difference corresponding to the time zone is automatically set. Is displayed in the box B2.

  On the other hand, when the user selects the “fixed” mode, the same time zone as the time zone set in the operation system OS of the PC 30 is set, and the shooting date and time TG by GPS is corrected based on the time zone. The shooting date and time is displayed on the display portion H.

  Usually, the time zone set in the operation system OS is the time zone where the PC 30 is installed. For example, when the PC 30 is installed in Japan, “GMT + 9” is set. The +9 hours are acquired and added to the GPS shooting date and time TG, thereby correcting the shooting date and time with reference to Japan time. That is, the “fixed” mode is a mode for displaying the shooting date and time in the local time in the area where the PC 30 is installed. This mode also does not use GPS location information.

  In the GUI screen on the display 43, when the target image is printed with the various setting items remaining in the default state, the shooting date / time in the local time is obtained by the shooting date / time correction process, and the corrected shooting date / time considering the daylight saving time is obtained. Calculated. The printer 50 outputs a print image in which the shooting date and time of the local time is displayed at a predetermined position. Even if the shooting date / time is corrected in the “automatic” mode, the user can correct the shooting date / time before printing.

  For example, if the position information by GPS of the selected image data is 74 degrees 01 minutes XX seconds west longitude and 40 degrees 43 minutes YY seconds north latitude (assuming that it is near New York), using the conversion table, The time difference from Greenwich Mean Time GMT is −5 hours (“GMT-5” North American Eastern Standard Time time zone). When the shooting date / time TG by the GPS at the time of shooting this image data is 14:30 on August 1, 2004, the local time of the shooting location is calculated as 9:30 on August 1, 2004. . Here, since August 1 is the daylight saving time application period (from the first Sunday in April to the last Sunday in April), 10:30 on August 1, 2004 is finally calculated as the local time of the shooting location. Is done.

  FIG. 6 is an example of a print result when printing of a selected image is executed with setting items relating to various shooting dates and times set as a default state. As shown in the figure, the shooting date and time based on the local time near New York is printed at the lower right of the image. The daylight saving time information corresponding to the shooting location is prepared in advance on the hard disk 34 in the PC 30 together with the conversion table. In consideration of daylight saving time, the shooting date is obtained from the shooting date and time TG (date) by GPS shown in FIG.

  As described above, according to the shooting date correction processing of the present embodiment, the position information of the shooting location accompanying the image data and the shooting date and time TG by GPS are acquired, and the shooting date and time by the local time of the shooting location is obtained using the conversion table. Is calculated and printed together with the image. In this shooting date correction process, the user only has to select an image and issue a print instruction, and there is no need to perform an input operation for the setting item. Therefore, it is possible to print an image with the shooting date and time corrected to local time without complicated operations.

  Further, even if the process of correcting the shooting date / time TG to the local time is performed, the shooting date / time TG of the image data is not rewritten, and the shooting date / time TG by GPS is recorded in the image data. Accordingly, when editing an image, such as when arranging a plurality of images in the order of shooting, the shooting date / time TG by GPS can be used as it is.

  Although the conversion table based on the time zone of this embodiment is provided with detailed data only for a specific place, it has detailed data near the boundary of the time zone where the time difference changes, and the other areas are in increments of 15 °. It is good also as a thing provided with comparatively coarse data. Further, it may be provided with data of the boundary portion of the time zone (see IR in FIG. 5) that is not expressed at intervals of 15 °, and other areas may be provided with relatively coarse data in increments of 15 °.

  By setting a conversion table based on such time zone data, it is possible to provide a conversion table that corrects the shooting date and time relatively accurately while suppressing the data capacity compared to the case of having time zone data all over the world. . Of course, as long as the data storage capacity is sufficient, detailed data from around the world may be provided.

C. Variation:
As mentioned above, although embodiment of this invention was described, this invention is not limited to such embodiment at all, Of course, it can implement with various forms within the range which does not deviate from the meaning of this invention. is there. In this embodiment, the shooting date and time in local time is printed together with the image, but a predetermined display may be added so that the user who viewed the print image can recognize that it is local time.

  For example, it is sufficient to add “time zone” to the shooting date and time of the print image shown in FIG. 6 and print “2004/08/01 10:30 (GMT-4)”. Further, instead of the time zone, a predetermined symbol or a predetermined color may be added. By doing so, it can be easily recognized that the printed shooting date / time is different from the normal shooting date / time (internal clock of the digital still camera 61).

  In this embodiment, as one mode of outputting the shooting date / time corrected to the local time, printing is performed together with the image. However, the shooting date / time corrected to the local time may be written in a predetermined file. For example, as shown in FIG. 7, if the data structure is in the Exif format, the corrected shooting date and time may be written in the manufacturer's note that is the user's use area, or the corrected shooting date and time is superimposed on the image data. May be written in the image data storage area.

  In this embodiment, the conversion table based on the time zone is stored in advance on the PC 30 side. However, the conversion table is provided on a predetermined server via the Internet (stored on the server). The time difference may be acquired via the Internet, or the time zone and daylight saving time information may be acquired. Of course, only the time zone or daylight saving time information may be acquired via the Internet.

  For example, a correspondence relationship between a position expressed by longitude and latitude and a time zone is prepared in advance in the server, and the time difference corresponding to the position information of the print target image is acquired by accessing the server. In this case, the PC 30 may be connected to the Internet via the I / F circuit unit 35 and acquire the time difference from a predetermined server. By doing so, it is possible to reduce the memory required for storing the program relating to the photographing date / time correction processing.

  Furthermore, in this embodiment, the position information for one image data and the shooting date / time TG by GPS are input, and the shooting date / time by local time is calculated using the conversion table. Instead, the shooting date and time TC (see FIG. 2) using the internal clock of the digital still camera may be used.

  For example, when the time difference from Greenwich Mean Time GMT in the place where the internal clock of the digital still camera is set is known in advance, the time zone of the shooting location is obtained from the position information of the image data, and the shooting date and time TC by the internal clock is set. On the other hand, the shooting date and time based on the local time of the shooting location may be calculated by taking into account the time difference from Greenwich Mean Time GMT of the internal clock known in advance and the obtained time zone. In this way, even when the image data does not have the GPS shooting date / time TG, the shooting date / time correction process can be performed.

  In this embodiment, the image data to be printed is acquired by the digital still camera 61 having a GPS wireless communication function. However, another imaging device, for example, a mobile phone having a camera function is used. It is good as a thing. Of course, the image data may be generated by any device as long as the image data includes the position information and the shooting date and time TG by GPS.

  In addition, when a mobile phone having a camera function is used, base station data may be used instead of acquiring position information through GPS wireless communication. For example, the location information of the nearest base station from the location where the image was taken with the mobile phone is acquired, the time difference is obtained from the location information of the base station using a predetermined conversion table set in advance, and the shooting date and time by the local time is calculated What should be done.
