Description

  The present invention relates to an image processing apparatus, an image processing method, a program, and a storage medium that specify the number of printed sheets of an image.

  2. Description of the Related Art Conventionally, it is widely performed to print an image taken or generated by a digital camera or the like. In particular, it is performed to print the number of captured images for distribution to the people shown in the images. In addition, face detection from an image is also performed for the purpose of performing image processing on the face portion of a person in the image (Patent Documents 1 to 3).

  By combining these, human faces are detected from the image, and the number of detected faces is used as the number of printed images (Patent Documents 4 to 6). In Patent Document 4, it is assumed that there is an error in face detection, and the operator can change the set number of prints.

JP-A-8-063597 JP 2001-216515 A JP 2002-183731 A Japanese Patent Laid-Open No. 9-281605 Japanese Patent Laid-Open No. 10-21003 JP 2003-219329 A

  However, the number of images to be printed is often different from the number of people in the image. For example, it may be possible to distribute a photograph such as a landscape where no person is shown to a plurality of people. Conversely, group photos are often taken multiple times in the same scene because there is a risk of shooting failure, but printing for the number of people is usually one image of them, the others are There is no need to print. In other words, there are some images that are not printed at all even if they contain a large number of people. Further, it is up to the operator to determine whether or not to print a failed photograph such as so-called defocus or camera shake even if a person is present.

  Although the number of printed sheets can be changed in the conventional technique, the number of faces detected from each image is set as the number of printed sheets in the first stage, so that the number of printed sheets is the number of faces in the image as described above. When printing is not necessary or when printing is not necessary, the operator has to repeat complicated operations for changing the number of printed sheets.

  Accordingly, an object of the present invention is to make it possible to easily set the number of prints of each image with reference to the number of faces detected from the image, based on designation of the number of prints according to the user's intention, with respect to the prior art. And

  The present invention has been made to achieve the above object, and according to the present invention, counting means (face detection unit 1007, 5006 or 9005) for counting the number of persons included in an image, Based on acquisition means (input control unit 1005, 5007 or 9006) for acquiring the number of printed sheets, comparison means (main control unit 1001, 5001 or 9001) for comparing the counted result with the number of printed sheets, and the comparison result. An image processing apparatus comprising warning means (display 1004, electronic viewfinder 5005 or display 9009) for issuing a warning and display means (display 1004, electronic viewfinder 5005 or display 9009) for displaying the counted result. Is provided.

  According to the invention, the counting step (step S101, S208 or S302) for counting the number of persons included in the image, and the acquisition step (step S102, S201 or S301) for acquiring the number of printed sheets of the image. A comparison step (step S103, S209 or S303) for comparing the counted result with the number of printed sheets, a warning step (step S104, S210 or S304) for issuing a warning based on the comparison result, and the counted result And a display step (step S104, S210 or S304) for displaying the image.

  According to the present invention, it is possible to obtain an effect that the user can easily set the number of prints of each image with reference to the number of faces detected from the image while basically specifying the number of prints according to his / her intention. . Also, at this time, there is no troublesome operation when the print setting is set for an image that the user originally does not intend to print, or when the number of prints is different from the number of people that the user clearly shows with intention. There is also an effect that it can be completed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<Embodiment 1>
FIG. 1 is a block diagram showing a functional configuration of an information processing apparatus to which an image processing apparatus showing an embodiment of the present invention can be applied.

  Reference numeral 1001 denotes a main control unit, which corresponds to a CPU that comprehensively controls each unit of the information processing apparatus. An image storage unit 1002 corresponds to a hard disk drive that stores image data to be printed and a work area in the RAM that temporarily stores the image data read from the hard disk drive. A display control unit 1003 controls display of images and characters on the display 1004. Reference numeral 1005 denotes an input control unit which performs input control of user operations via the keyboard / mouse 1006. A user of the information processing apparatus performs interactive operation of the information processing apparatus using the display 1004 and the keyboard / mouse 1006.

  Reference numeral 1007 denotes a face detection unit that detects a position where a human face is drawn from the acquired image data and counts the number of the positions. Many methods such as Patent Documents 1 to 3 have been proposed as face detection methods, and any of these methods may be used in the present invention, and the method is not limited to these methods. Various methods may be used. Regarding the face detection, conventional techniques are disclosed in various documents, and thus detailed description thereof is omitted here.

  A print control unit 1008 controls output of an image or the like to the printer 1009 connected to the information processing apparatus.

  FIG. 2 is a diagram showing a display example on the display 1004. These displays are performed when the display control unit 1003 displays an image acquired from the image storage unit 1002 on the display 1004 according to the control of the main control unit 1001.

  A folder selection unit 2001 displays a list of logical folders in which image data is classified and stored in the image storage unit 1002. When any folder is selected in the folder selection unit, the image data classified in the folder becomes a print candidate.

  Reference numeral 2002 denotes a thumbnail display unit, which displays a reduced version of each image that is a candidate for printing. Reference numeral 2003 denotes a print number setting unit, which displays the number of prints of the image displayed on the thumbnail display unit 2002 associated with the print number setting unit. Further, the user can input and change the number of prints to the print number setting unit 2003 by operating the keyboard / mouse 1006.

  Reference numeral 2004 denotes a print start button. When the print start button 2004 is selected by operating the keyboard / mouse 1006, the information processing apparatus performs the following print processing.

  FIG. 3 is a flowchart showing the procedure of the printing process performed when the print start button 2004 is selected.

  First, in step S101, one of the images to be printed is acquired from the image storage unit 1002, the face detection unit 1007 detects the position of a human face in the image, and counts the number.

  In step S102, print number data set in advance by the print number setting unit 2003 in FIG. 2 is acquired for the image to be printed.

  In step S103, the number of faces counted in step S101 is compared with the number of printed sheets acquired in step S102. If they match, the process proceeds to step S106, and if they do not match, the process proceeds to step S104. In step S104, a warning dialog is displayed on the display 1004. FIG. 4 is a diagram showing an example of the warning dialog. Reference numeral 4001 denotes a thumbnail display unit, which is similar to the thumbnail display unit 2002 in FIG. However, in the thumbnail display portion 4001 of the warning dialog, a mark 4002 is added to the portion corresponding to the face of the person detected in step S101.

  Reference numeral 4003 denotes a detected number display unit that displays the number of faces of the person counted in step S101. Reference numeral 4004 denotes a print number setting unit, which is the same as the print number setting unit 2003 in FIG. In the warning dialog, the number of prints setting unit 4004 displays the number of prints based on the number of prints acquired in step S102 in the initial state. Similar to the print number setting unit 2003 in FIG. 2, the user can change the print number by an operation via the keyboard / mouse 1006.

  A message display unit 4005 displays a warning message for the user. Reference numeral 4006 denotes an OK button. When this button is selected by a user operation via the keyboard / mouse 1006, an image displayed on the image display unit 4002 is displayed with the numerical value displayed on the print number setting unit 4004 at this time. The number of prints is determined and the dialog processing is terminated.

  In step S105, the number of prints determined in the dialog process in step S104 is acquired.

  In step S <b> 106, the image to be printed is printed by the printer 1009 via the print control unit 1008. At this time, image printing is performed according to the number of prints acquired in step S102 or updated in step S105.

  In step S107, it is determined whether or not the processing has been completed for all print candidate images included in the folder selected by the folder selection unit 2001 in FIG. If not completed, the process returns to step S101, and the process for the next image included in the folder is continued. When all the images have been processed, a series of printing processes are ended.

  Through the above processing, the user can arbitrarily set the number of prints of each image. Further, when the number of printed sheets is different from the result of face detection and counting, a warning notification can be received, so that the number of printed sheets can be changed as necessary to prevent a mistake in setting the number of printed sheets.

  In the above processing, all the images included in the folder selected by the folder selection unit 2001 in FIG. 2 are processed, but for example, for the image in which 0 is set in the print number setting unit 2003 in FIG. The entire process or steps S103 to S105 may be omitted. This can prevent a warning dialog from being displayed for an image that the user originally did not intend to print, such as a failed photo.

  Similarly, an image in which no human face is detected by the face detection unit 1007 is printed as the number of prints acquired in step S102 without performing the determination in step S103, or is detected and counted by the face detection unit 1007. If the number of printed faces and the number of printed sheets acquired in step S102 are extremely different, it is possible to perform printing according to the number of printed sheets acquired in step S102 without performing the determination in step S103. As a result, it is possible to avoid displaying a warning dialog when it is considered that the number of prints is clearly set by the user's intention.

  The warning dialog in FIG. 4 displays a reduced version of the image as in FIG. 2, but a higher-definition image or an enlarged image display function is provided so that the details of the image can be confirmed. It may be provided.

  Conversely, the mark 4002 indicating the face may not be displayed in the warning dialog of FIG. In this case, the face detection unit 1007 does not need to record the position of each detected face.

<Embodiment 2>
FIG. 5 is a block diagram showing a functional configuration of an imaging apparatus to which the image processing apparatus showing the embodiment of the present invention can be applied.

  Reference numeral 5001 denotes a main control unit, which corresponds to a CPU that comprehensively controls each unit of the imaging apparatus. An imaging unit 5002 converts an image to be captured into electronic image data. A combination of an optical system, an image sensor, an image processor, and the like corresponds to this. Reference numeral 5003 denotes an image storage unit, which corresponds to a memory or the like for storing image data generated by the imaging unit 5002. Reference numeral 5004 denotes a display control unit which controls display of images and characters on the electronic viewfinder 5005.

  Reference numeral 5006 denotes a face detection unit that detects a position where a human face is drawn from the acquired image data and counts the number of the positions. The face detection unit 5006 has the same function as the face detection unit 1007 in the first embodiment.

  Reference numeral 5007 denotes an input control unit that performs input control of user operation via the key 5008. The user of the imaging apparatus captures an image by operating the key 5008, and interactively performs various settings for the imaging apparatus and the captured image using the electronic viewfinder 5005 and the key 5008. In particular, for each photographed image, DPOF (Digital Print Order Format) data indicating the number of prints of the image can be set and recorded as data accompanying the image data. For this reason, the imaging apparatus according to the present embodiment includes “print number setting”, “+”, “−”, and “OK” keys. Note that the normal image pickup apparatus has other keys such as a power key and a shutter key in addition to the four keys.

  FIG. 6 is a view showing a display example of the electronic viewfinder 5005 when setting the DPOF data. The display control unit 5004 displays an image obtained from the image storage unit 5003 based on the control of the main control unit 5001 when the “print number setting” key is pressed after the image is captured. It is done by displaying on. The print number setting function may be activated by another operation.

  An image display unit 6001 displays a reduced version of a captured image. Reference numeral 6002 denotes a print number setting unit, which displays the number of prints of an image corresponding to the currently displayed thumbnail on the image display unit 6001. Further, the user can input and change the number of prints to the print number setting unit 6002 by operating the “+” and “−” keys.

  Reference numeral 6003 denotes a message display unit which displays an operation guide for the print number setting function.

  FIG. 7 is a flowchart showing a processing procedure of the print number setting function.

  First, in step S201, an image for which the number of prints is to be set is acquired from the image storage unit 5003, and the current set number of prints for the image is acquired, and these are displayed in the electronic viewfinder 5005 in the format shown in FIG. To display.

  In step S202, it is determined whether or not the “+” key has been pressed via the input control unit 5007. If it has been pressed, the process proceeds to step S203, and if not, the process proceeds to step S204.

  In step S203, the print number setting value is incremented by 1, and the process returns to step S201. However, if the set number of printed sheets has already reached 99 when the process proceeds to step S203, the increase is not performed.

  In step S204, it is determined whether or not the “-” key has been pressed via the input control unit 5007. If it has been pressed, the process proceeds to step S205, and if not, the process proceeds to step S206.

  In step S205, the set number of printed sheets is decreased by 1, and the process returns to step S201. However, if the set number of printed sheets is already 0 at the time of shifting to step S205, the reduction is not performed.

  In step S206, it is determined whether or not the “OK” key has been pressed via the input control unit 5007. If it has been pressed, the process proceeds to step S207. If not, the process returns to step S201 to continue the setting process.

  In step S207, it is determined whether a warning described later has already been displayed. If already displayed, the process proceeds to step S210. If not displayed, the process proceeds to step S208.

  In step S208, an image to be printed is set from the image storage unit 5003, the face detection unit 5006 detects the position of a human face in the image, and the number is counted.

  In step S209, the current set number of printed sheets is compared with the number of faces counted in step S208. If they match, the process proceeds to step S210. If the current set number of prints does not match the counted number of faces, the process proceeds to step S211.

  In step S210, the current print number setting value is confirmed and written as DPOF data in the image storage unit 5003, and the series of processing ends.

  In step S211, a warning is displayed on the electronic viewfinder 5005 via the display control unit 5004, and the process returns to step S201. FIG. 8 is a diagram showing a display example of the warning. Reference numeral 8001 denotes an image display unit, which is similar to the image display unit 6001 in FIG. However, in the image display portion 8001 at the time of warning display, a mark 8002 is added to the portion corresponding to the face of the person detected in step S208.

  Reference numeral 8003 denotes a detected number display unit that displays the number of faces of the person detected in step S208. Reference numeral 8004 denotes a print number setting unit, which is similar to the print number setting unit 6002 in FIG. A message display unit 8005 displays a warning message for the user.

  Once the warning is displayed in step S211, display on the electronic viewfinder is also performed in the format shown in FIG. 8 even when the image and the print number set value are displayed in step S201.

  Through the above processing, the user can arbitrarily set the number of printed images. Further, when the number of printed sheets is different from the result of face detection and counting, a warning notification can be received, so that the number of printed sheets can be changed as necessary to prevent a mistake in setting the number of printed sheets.

  In the above process, when the warning is not displayed and the OK key is pressed, the set number of printed sheets is always compared with the number of faces, and a warning is displayed when there is a mismatch. For example, for an image for which 0 is set in the printed number setting unit 6002 Can be made to proceed directly to step S210 after the OK key depression determination in step S206. As a result, it is possible to avoid a warning from being displayed for an image that the user originally did not intend to print, such as a failed photo.

  Similarly, for the image in which no human face is detected by the face detection unit 5006, the determination in step S209 is not performed, or the number of faces detected and counted by the face detection unit 5006 and the set number of printed sheets are extremely large. If they are different, the determination in step S209 may not be performed. As a result, it is possible to avoid displaying a warning when it is considered that the number of printed sheets is clearly set according to the user's intention.

  Note that although the warning in FIG. 8 displays the entire image on the image display unit 8001 in the same format as in FIG. 2, an enlarged image display function may be provided so that the details of the image can be confirmed.

  Further, the mark 8002 indicating the face may not be displayed in the warning of FIG. In this case, the face detection unit 5006 need not record the face position.

<Embodiment 3>
FIG. 9 is a block diagram illustrating a functional configuration of a printing apparatus to which the image processing apparatus according to the third embodiment of the present invention can be applied.

  A main control unit 9001 corresponds to a CPU that performs overall control of each unit of the printing apparatus. An interface unit 9002 receives image data and print number designation data from a host (not shown). As long as the host can communicate with the printing apparatus of the present embodiment using a specific protocol and can transmit image data and print number designation data, an information processing apparatus such as a PC or an imaging apparatus such as a digital camera may be used. Various devices such as a communication device such as a mobile phone can be used.

  A reception buffer 9003 corresponds to a memory that temporarily stores the image data and print number designation data received by the interface unit 9002. An image recording unit 9004 records an image on a print medium based on the received image data and print number designation data in accordance with the control of the main control unit 9001. Examples of the recording method include, but are not limited to, an electrophotographic method, an inkjet method, and a thermal transfer method.

  Reference numeral 9005 denotes a face detection unit that detects a position where a human face is drawn from the image data stored in the reception buffer and counts the number thereof. The face detection unit 9005 has the same function as the face detection unit 1007 in the first embodiment.

  Reference numeral 9006 denotes an input control unit which performs input control of user operation via a key 9007. A display control unit 9008 controls display of images and characters on the display 9009. A user of the printing apparatus interactively performs various settings for the printing apparatus and the print image using the key 9007 and the display 9009. In particular, an operation for changing the number of printed sheets of each image can be performed. For this reason, the printing apparatus of the present embodiment includes “+”, “−”, and “OK” keys. The printing apparatus usually has other keys such as a power key and a reset key in addition to the above three keys.

  FIG. 10 is a flowchart showing a processing procedure during a printing operation of the printing apparatus according to the present embodiment.

  First, in step S 301, image data to be printed and print number designation data are acquired in the reception buffer 9003 via the interface unit 9002.

  In step S302, the face detection unit 9005 detects the position of the face of the person from the image data acquired in the reception buffer 9003, and counts the number.

  In step S303, the print number designation data acquired in step S301 is compared with the number of faces counted in step S302. If they match, the process proceeds to step S310, and if they do not match, the process proceeds to step S304.

  In step S304, a warning is displayed on the display 9009 via the display control unit 9008. The warning display content is the same as that shown in FIG. At this time, the user can change the print count designation data transmitted from the host by operating the key 9007.

  In step S305, it is determined whether or not the “+” key has been pressed via the input control unit 9006. If it has been pressed, the process proceeds to step S306, and if not, the process proceeds to step S307.

  In step S306, the print number designation value is incremented by 1, and the process returns to step S305. However, if the set number of printed sheets has already reached 99 when the process proceeds to step S306, the increase is not performed. When the print number designation value is increased, the display value of the print number setting unit 8004 on the display 9009 is also updated.

  In step S307, it is determined whether or not the “−” key has been pressed via the input control unit 9006. If it has been pressed, the process proceeds to step S308; otherwise, the process proceeds to step S309.

  In step S308, the print number designation value is decreased by 1, and the process returns to step S305. However, if the print number designation value is already 0 at the time of shifting to step S308, the reduction is not performed. When the print number designation value is decreased, the display value of the print number setting unit 8004 on the display 9009 is also updated.

  In step S309, it is determined whether or not the “OK” key has been pressed via the input control unit 9006. If it has been pressed, the process proceeds to step S310. If not, the process returns to step S305 to continue the process.

  In step S310, the image recording unit 9004 is driven, and the image data is printed for the number of final print number designation values.

  With the above processing, the user can receive a warning notification when the print number designation data designated by the host is different from the face detection and counting results. Can be prevented.

  For the image in which no human face is detected by the face detection unit 9005, the determination in step S303 is not performed, or the number of faces detected and counted by the face detection unit 9005 and the set number of prints designated by the host If the values are extremely different, the determination in step S303 may not be performed. As a result, it is possible to avoid displaying a warning when it is considered that the number of printed sheets is clearly set according to the user's intention.

  Although the entire image is displayed on the image display unit 8001 in the warning of FIG. 8, an enlarged image display function may be provided so that details of the image can be confirmed.

  Further, the mark 8002 indicating the face may not be displayed in the warning of FIG. In this case, the face detection unit 9005 need not record the face position.

  In the present embodiment, the printing apparatus has the display 9009 and displays the warning shown in FIG. 8. However, when bidirectional communication is possible with the interface with the host, the above-described protocol is used by using an appropriate protocol. A warning may be displayed on a display on the information processing apparatus, imaging apparatus, or communication apparatus side that is a host, and the number of prints may be changed by operating a key or the like on the host side. Since the information processing apparatus usually has a display with a higher resolution than the printing apparatus or is connected to it, this allows the user to check the image in more detail when changing the print number designation.

  In this embodiment, the printing apparatus receives image data and print number designation data from an external host via the interface unit 9002. However, the printing apparatus incorporates or connects an image reading unit or imaging unit to the printing apparatus, and a key. May be provided to obtain image data from the image reading unit or the imaging unit, and obtain print number designation data using the print number setting function.

  Further, a memory card reader device may be built in or connected to the printing device, and image data and print number designation data may be acquired from a memory card or the like inserted in the memory card reader device. In the configuration having the memory card reader, the print number designation data may be obtained by a print number setting function using the key.
