If selected full paper Printing Qptions, then at operation S22, camera DSP 125 compares screen width high ratio (width: the ratio of height hereinafter is called the ratio of width to height) and the ratio of width to height of printed material of image.If the comparative result indication has selected the ratio of width to height of full paper Printing Qptions and image and the ratio of width to height of printed material in fact to match each other, then do not need to consider the shearing of facial zone, therefore, according to operation S21, the print area of initial setting up is identified, then, if imported final print command from the user, then the print job according to this order is performed.But if selected full paper Printing Qptions, and the ratio of width to height of image is different with the ratio of width to height of printed material, for example, if with the ratio of width to height of printed image is 4: 3, and the ratio of width to height of printed material is 3: 2, then begin to carry out the face recognition processing of explained later at operation S23.

Face recognition processing (operation S23)

At first, camera DSP125 operation Exif information process unit 122 extracts face recognition information thus from the Exif head of view data.For example, Exif information process unit 122 is from the face recognition information extraction data relevant with facial zone (for example, the coordinate figure (X1 of starting point, Y1, A1, B1), the horizontal length and the vertical length of facial zone), and these data are outputed to camera DSP125.(A1 B1) can be based on the X and Y coordinates on the screen on the basis of pixel arrangement for X1, Y1 for coordinate figure.Coordinate (X1, Y1) the starting point position of indication facial zone, coordinate (A1, B1) indication with from starting point (X1, Y1) width of the facial zone of Ji Suaning and being worth highly accordingly.

If face recognition information is not recorded in the Exif head, for example, if obtained coordinate figure (X1 from Exif information process unit 122, Y1, A1, B1)=(0,0,0,0) (the NULL state that does not have the input of coordinate figure), then camera DSP125 is sent to facial zone extraction unit 128 with image.The facial zone extraction unit 128 that has received view data is carried out preliminary treatment, and extracts border element based on the distribution that appears at the luminance signal on the pretreated image.Then, by the edge image that facial recognition techniques is applied to extract like this, facial characteristic element (such as profile, eye, nose and the mouth of face) is detected.According to detected characteristic element detection faces portion zone usually.For example, in facial recognition techniques, compare by the edge image that will extract and model based on shape research, can detect facial characteristic element, and determine whether to obtain facial zone according to testing result (for example, according to whether obtaining an eye zone and a mouth zone).In this case, also can detect a plurality of facial zones from a screen picture.Can produce data from the facial zone that is provided with, for example (A1 B1), horizontal width and vertical width, and can indicate the facial zone of setting by the facial zone that is centered on by rectangle frame on screen for X1, Y1 as the coordinate figure of the starting point of facial zone.

As mentioned above, can perhaps, realize face recognition by extracting face recognition information from Exif head with printed image by carrying out face recognition algorithm to extract facial zone from image.Yet technical scope of the present invention is not limited to aforesaid example, also can realize face recognition by the known the whole bag of tricks in the conventional art.

Then, S24 determines whether detect effective facial zone in face recognition processing (S23) in operation, if and do not detect facial zone, then do not need to consider the shearing of facial zone, therefore, according to operation S21, camera DSP125 can confirm the print area and the execution print procedure subsequently of initial setting up.Yet if obtain effective facial zone in face recognition processing (S23), at operation S25, camera DSP125 compares the facial zone of acquisition and the print area of initial setting up, checks thus whether facial zone is included in the print area.For example, print area appropriateness determining unit 127 is with the coordinate figure (X1 of the starting point of facial zone, Y1, A1, B1), coordinate figure value (pX, pY, the pW of the starting point of horizontal width and vertical width and print area, pH), horizontal width and vertical width compare, and can confirm whether facial zone is included in the print area.

According to check result, if facial zone is present within the print area of initial setting up, then confirm print area according to operation S21, and if imported user's final print command, then correspondingly carry out print job.Yet,, carry out the adjustment of print area if determine that facial zone is not included in the print area.At first, in operation S26, the relation between the ratio of width to height of camera DSP125 check image and the ratio of width to height of printed material.The operation S27 to S33 that is described below, according to check result, camera DSP125 adjusts print area according to diverse ways.

The adjustment (S27 to S33) of print area

1) if the ratio of width to height of image less than the ratio of width to height of printed material, for example, if the ratio of width to height of image is 4: 3, the ratio of width to height of printed material is 3: 2, then according to operation S27, print area is moved predetermined degree up and down.In this case, with respect to moving direction, print area moves up and down towards the direction that has the facial zone outside the print area, and can determine the adjusting range of print area with reference to the distance between the characteristic element that obtains in facial zone.Promptly, as described above with reference to Figure 3, camera DSP125 can be arranged in the entire image of printing the facial zone that comprises the people on second vertical height (Py2) by the top side with print area, (Py2=Py1+h1 * α) obtains second vertical height (Py2), and equation 1 comes from distance (h1) and weight (α) between first vertical height (Py1), eye zone and the mouth zone in eye zone from equation 1.If according to the research based on ordinary people's shape, distance between eye and the mouth and the distance between the eye and the crown are approximate, and then weight (α) can be set to 1.

2) if the ratio of width to height of image greater than the ratio of width to height of printed material, for example, if the ratio of width to height of image is 16: 9, the ratio of width to height of printed material is 3: 2, then according to operation S28, camera DSP125 determines whether have the face that is positioned at outside the print area on the left side and the right side of image at operation S28.Promptly, be present in both sides if determine first facial zone and second facial zone on image, discerned, promptly, the left side of image and right side, and these two facial zones are positioned at outside the print area, and then camera DSP125 can not be left at random adjusts print area on direction and any one direction in right.Therefore, at operation S29, showing zone and the alert message of getting rid of outside printing on the display floater 124.Then, if sense user's the input that is used for the mobile print zone (for example, sensing the operation of 4 direction function keys), then at operation S30, camera DSP125 comes the mobile print zone according to user's input, and process subsequently is performed.

Yet, at operation S31, if facial zone is present in outside the print area in any side in left side and right side, for example, if determining the left side of facial zone is positioned at outside the print area, then, adjust print area by print area being moved to the left, thereby the entire face zone can be included in the print area with a part that is positioned at outside the print area that comprises facial zone at operation S32.In addition, if S31 determines that the right side of facial zone is positioned at outside the print area in operation, then at operation S33, adjust print area by print area is moved right with a part that is positioned at outside the print area that comprises facial zone, thereby the entire face zone can be included in the print area.

Figure 10 is the flow chart that is illustrated in the example of having confirmed after the print area printing that will be performed.If sense user's final print command at operation S34, then at operation S35, have only being extracted with printed image with the corresponding part of print area, and being converted into can be by the print data of photo printer 110 recognition data forms, and data converted is sent to photo printer 110.In this case, as the data that will be sent to photo printer 110, have only the corresponding part of print area with being provided with of image to be extracted and to send, perhaps entire image also can be sent out the area information of specifying print area to append to.

Then, along with receiving print data, the print job of photo printer 110 begins (S36).More particularly, printer DSP115 will be stored in the memory cell 118 from the print data that digital camera 120 receives temporarily, and the commencing signal of output print simultaneously operate print unit 119 thus, thereby the print data in the memory cell 118 can be output on the printed material.

Simultaneously, the image memory device that is implemented as digital camera 120 has the memory function of memory image, self operation controlled function (DSP function) and Presentation Function.The example of image memory device is digital camera and digital TV.Yet know-why in fact of the present invention also can be applied to the situation of small-sized storage device as image memory device comparably, and small-sized storage device does not have cpu function and the Presentation Function of himself, for example detachable memory.Shown in Figure 11 according to this structure of whole photo-printing system of using example.
