Description

  The present invention relates to a group photo editing device and a program.

  At events such as school events, group trips, weddings, etc., group photos in which a plurality of participants gather are often taken. For example, a professional photographer takes a group photo and uses a personal computer or the like to perform editing processing such as text insertion or trimming on the captured image. The character insertion is input / composition of character information such as an event name and a shooting date. Trimming is performed to match the size of the captured image to the size of the print paper.

  Generally, a digital camera that captures a group photo generates a captured image with an aspect ratio of 3: 2, 4: 3, 16: 9, or the like. On the other hand, a general 2L version as a sheet for printing a group photograph has an aspect ratio of about 1.4: 1, and the 2Lw version has an aspect ratio of about 1.5: 1. If the aspect ratio is different between the photographed image and the print paper, the top and bottom and left and right of the image are not printed. Therefore, trimming has been performed in advance.

  Trimming is a time-consuming operation because it is necessary to ensure that the character input area is secured and to prevent the face images of the subjects located at the upper, lower, left, and right ends from being cut off. Further, when photographing, it is necessary to determine the photographing position and angle while paying attention to the "place for putting characters in the group photograph", which is a difficult task for photographers such as photographers.

FIG. 2 is a block diagram of the image printing apparatus. FIG. 2 is a perspective view of the image printing apparatus.

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

  As shown in FIGS. 1A and 1B, a group photo editing device 10 according to an embodiment of the present invention edits an image of a group photo taken by a photographing device C such as a digital camera. The image data edited by the group photo editing device 10 is transferred to the printer P. The printer P prints the image on a sheet to produce a group photograph S.

  As shown in FIG. 2, the group photographing apparatus 10 includes a CPU (central processing unit) 11, a memory 12, a display unit 13, an input unit 14, and a communication unit 15, and for example, a computer can be used.

  The display unit 13 is, for example, a liquid crystal display. The input unit 14 is a keyboard or a mouse. The touch panel may constitute the display unit 13 and the input unit 14.

  The memory 12 includes a ROM (Read Only Memory), a RAM (Random Access Memory), a nonvolatile memory, a hard disk device, and the like. The memory 12 stores a group photo editing program downloaded by the communication unit 15 from a predetermined website via the Internet.

  When the CPU 11 executes the group photo editing program, as shown in FIG. 3, the face extracting unit 101, the print size determining unit 102, the cutout region determining unit 103, the text region determining unit 104, the character synthesizing unit 105, and the print processing are performed. The function of the unit 106 is realized, and the editing process of the captured image of the group photo captured by the camera C can be performed.

  The photographed image data may be transferred from the photographing device C to the group photograph photographing device 10 via a wireless network, or the memory card in which the photographed image is written may be removed from the photographing device C, and the card slot of the group photograph photographing device 10 May be input to the group photographing apparatus 10.

  The face extraction unit 101 extracts a person's face from a captured image. The top and bottom of the captured image may be determined from the position of the person's face.

  The print size determination unit 102 detects the positions of the faces of the persons at the left and right ends of the plurality of extracted faces of the persons, and determines the print size of the group photograph. For example, as shown in FIG. 4, the print size determination unit 102 detects the position of the face of the person F1 at the leftmost position in the image and the position of the face of the person F2 at the rightmost position in the image.

  The print size determination unit 102 calculates the ratio between the length d1 from the face of the person F1 to the left end of the image and the width W of the entire image, the length d2 from the face of the person F2 to the right end of the image, and the width W of the entire image. Are calculated, and the print size is determined based on these ratios. For example, if the ratio between the length d1 and the width W and / or the ratio between the length d2 and the width W is 10% or more, the print size is determined to be 2L, and the ratio between the length d1 and the width W is determined. If the ratio between the length d2 and the width W is less than 10%, the print size is determined to be 2Lw. That is, when the positions of the faces of the persons at the left and right ends are close to the left and right ends of the image, a horizontally long print sheet is used. The threshold value of the ratio for determining the print size can be set arbitrarily.

  The cut-out area determination unit 103 determines a cut-out area in the height direction of the image in consideration of the position of the text area in which characters are to be inserted. The text area is arranged at the upper or lower part of the image, and whether it is arranged at the upper or lower part is set in advance.

  For example, as shown in FIG. 5A, when the text area T is arranged at the lower part of the image, the cut-out area determining unit 103 selects the uppermost person F3 among the plurality of extracted faces of the persons. A face is detected, and a cutout line L1 is set at a position of a predetermined number of pixels above the face position. In addition, the cutout area determination unit 103 sets the lower cutout line L2 based on the position of the cutout line L1 and the print size. In the captured image, an area above the cut-out line L1 and an area below the cut-out line L2 (shaded area in the drawing) are areas where no printing is performed.

  When arranging the text area T at the top of the image, the cutout area determination unit 103 detects the face of the lowest person among the plurality of extracted faces of the person, and determines the predetermined face downward from the position of this face. Set the lower cutout line at the position of the number of pixels. Alternatively, the body (foot) of the person located at the bottom is detected, and a cutout line is set at a position of a predetermined number of pixels below the detected body (foot) position.

  The text area determining unit 104 determines the position of the text area so as to have a predetermined height from the upper end or the lower end of the cutout area of the captured image. For example, as shown in FIG. 5A, the text area determination unit 103 arranges a text area T having a height H above the cutout line L2. If the distance between the text area T and the face of the person F4 located at the bottom is less than the predetermined number of pixels, a warning may be issued and the height H of the text area T may be changed.

  The character combining unit 105 combines character information input via the input unit 14 into a text area. For example, as shown in FIG. 5B, character information is combined with the text area T. The font and size of the character can be arbitrarily changed.

  The print processing unit 106 cuts out the captured image with a cutout line, transfers the print image in which the text information is combined with the text area T to the printer P via the communication unit 15, and instructs the print size. The printer P prints and outputs a print image on a sheet of a designated size. As a result, a group photograph S as shown in FIG.

  As described above, the group photo editing apparatus 10 according to the present embodiment determines the suitable print size from the position of the person's face in the captured image, and matches all the faces in the captured image according to the print size. Cut out the image so that it contains and place the text area. Therefore, it is possible to reduce the work load of the group photograph editing process by the photographer or the like.

  It is preferable that the group photo editing apparatus 10 confirms that all the persons in the captured image are captured from the top of the face to below the chin. When a person whose top is not shown is included, the group photo editing apparatus 10 may exclude the captured image from being edited.
