Description

  The present invention relates to a print creation system and a print creation method for creating one print from a face photograph obtained by individually photographing a plurality of persons.

  Conventionally, a group photo in which a plurality of aligned persons are photographed with a background is known.

  In addition, a photograph in which a plurality of face photographs obtained by individually photographing a plurality of persons are arranged in one sheet or an album arranged in one page is known. The school graduation album is a typical example.

  Unlike the group photo in which the body is photographed together with the background, such a photo or album inevitably attracts attention to individual faces because only face photos are arranged. Therefore, it is hoped that the person who is the subject will be able to put a facial photograph with a good expression as much as possible.

  Regarding the creation of such a photo or album, an image processing system that performs layout processing after performing standardization processing to make the face size in each face photo constant (see, for example, Patent Document 1). However, there is no mention of correspondence regarding facial expressions in facial photographs.

  In particular, a commemorative photo in which a face photograph obtained by individually shooting participants who have gathered for a certain purpose is arranged on a background suitable for the purpose, such as a background of scenery, patterns, commemorative characters, etc. In photographs, the facial expressions arranged in the photographs are important as an impression of how the gathering was.

However, it is difficult to select a photograph with a good expression to be put on a commemorative photograph from a plurality of photographs in a short time.

The image data reading means 2 is means for reading image data from a digital camera, a memory card or the like. The image data storage means 3 is a magnetic disk, which is a known technical means, and can store a plurality of files therein. The printing means 4 is a printer, and the system can be appropriately selected from inkjet, thermal sublimation transfer, silver salt, and the like.

  FIG. 2 is a flowchart showing the flow of face image selection processing by the face image selection means 10 which is a program in the print creation system of the present invention.

  When the personal code of the person to be put on the commemorative photo is input (step S1: Y), the face image reading means 100 as a program is executed, and the personal code, the face image data name, and the face image data (face image) are stored. The face image file 100 which is a file provided in the image data storage means 3 is searched (step S2).

  All face image data names and face image data having the input personal code are extracted and stored in the face image extraction file 110 (steps S3: Y, S4).

  Further, the number K (extraction number) of the face image data stored corresponding to the personal code is stored in the extraction data number file 120 (step S5).

  The face image data stored in the face image extraction file 110 is sequentially read out using the face image data name as a key, and the degree of smile is determined by smile determination means 200 which is software described later.

  First, the value N of the read counter CN is set to 1 (step S6), and the face image data having the first face image data name is read from the face image extraction file 110 (step S7).

  The degree of smile is determined by the smile determination means 200 in the read face image data (step S8), and the determination result is stored in the smile determination result file 210 together with the face image data name (step S9).

  Next, 1 is added to the value N of the read counter CN (step S10), and when the value of N is equal to or less than the number K of face image data stored corresponding to the personal code (step S11: N) Returning to step S7, the process of steps S7 to S11 is repeated, whereby the face image data of the next face image data name is read, the degree of smile is determined, and the determination result is stored in the smile determination result file 210. Remembered.

  When the value of N exceeds the number K of face image data stored corresponding to the personal code (step S11: Y), the degree of smile of the face image data stored corresponding to the personal code All the determinations are completed.

  When the determination is completed, a determination result stored in the smile determination result file 210, that is, a face image data name and face image data whose numerical value indicating the degree of smile is closest to a preset value is selected and output face The image file 300 is stored (step S12), and the routine is exited.

  In this way, the personal code is sequentially input, the corresponding face image data is read from the face image file, the degree of smile is determined by the smile determination means 200, and the face image data selected based on the determination result is the output face image. It is stored in the file 300.

  When a plurality of face image data stored in the output face image file 300 is subjected to a print output process 400 as a program, the print unit 4 outputs a single print in which the plurality of face images are arranged.

  FIG. 3 is a flowchart showing the flow of print output processing.

  First, when the personal code of the person to be output is input to the print to be created (step S31: Y), the output face image file 300 storing the selected face image data is searched, and the face image data is stored. Read (step S32). The read face image data is subjected to normalization processing so that the face image has a predetermined size set in advance on the print (step S33).

  Next, a layout process for determining the layout of the face image created on the basis of the face image data is performed (step S34). The processes of steps S31 to S34 are performed for all the persons to be output on the print, Based on the input information from the operation display means 1 that the processes corresponding to all persons have been completed (step S35), the print output process to the printing means 4 is executed (step S36).

  FIG. 4 is an example of an output print.

  As shown in the figure, commemorative characters (indicated by circles) inputted in advance from the operation display means 1 are output at the upper part of the scenery, and smile images of a plurality of persons are output at the lower part. A personal name specified from the personal code may be output below the smiley image.

  Next, the smile determination process by the smile determination means 200 in the flowchart showing the flow of the face image selection process in FIG. 2 will be described.

  Smile determination starts with a process of detecting a designated facial part from a face image.

  FIG. 5 is a diagram showing a face part to be designated.

  The face parts to be designated are the external eye corner points a and b and the mouth corner points c and d. As shown in the figure, the smile determination means 200 has a vertical length y and a horizontal direction of a rectangle afbe formed from the four detected portions, that is, the line segments passing through the external eye corner points a and b and the mouth corner points c and d. This is software for determining a smile by setting the ratio R = x / y to the length x as the degree of smile.

  This software is based on experimental data that many smiles have R = 1.63 ± 0.04, and is a known technique. In the case of no expression, an experimental result of R = 1.40 ± 0.07 is obtained. Such a difference appears due to the movement of the greater zygomatic muscle that raises the corner of the mouth.

  FIG. 6 is a diagram showing experimental results obtained by measuring the smile degree R described above.

  FIG. 7 is a flowchart showing the flow of smile determination processing by the smile determination means 200.

  When face image data is read from the face image extraction file (FIG. 2, step S7), as already described, the outer eye corner point and mouth corner point are detected (step S41), and a rectangle is drawn (step S42). R = x / y, which is the degree of smile, is calculated. The obtained value is stored in the smile determination result file 210 (FIG. 2, step S9).

  As described above, according to the present invention, one smile image is automatically selected for each individual from a face image file storing a personal face image together with a personal code, and a plurality of smile images of a plurality of persons are determined in advance. A print creation system and a print creation method for creating a commemorative photo arranged in a position are realized.
