Description

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

At school events, group trips, weddings, and other events, group photos of multiple participants are often taken. For example, a professional photographer takes a group photo and uses a personal computer or the like to edit the shot image, such as inserting characters and trimming. Character insertion is input / composition of character information such as the event name and shooting date. Trimming is performed to match the size of the captured image to the size of the printing paper.

Generally, a digital camera that takes a group photograph generates a photographed image with an aspect ratio of 3: 2, 4: 3, 16: 9, or the like. On the other hand, the aspect ratio of the 2L version, which is generally used for printing group photographs, is about 1.4: 1, and the aspect ratio of the 2Lw version is about 1.5: 1. If the aspect ratio of the captured image and the print paper are different, the top, bottom, left, and right of the image will not be printed. Therefore, trimming was performed in advance.

Trimming was a laborious task because it was necessary to secure a character insertion area and not to cut off the facial image of the subject located at the top, bottom, left, and right edges. In addition, when shooting, it is necessary to determine the shooting position and angle while being aware of the "location of characters in the group photo", which is a difficult task for photographers such as cameramen.

It is a block diagram of an image printing apparatus. It is a perspective view of an image printing apparatus.

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

As shown in FIGS. 1A and 1B, the group photo editing device 10 according to the embodiment of the present invention edits an image of a group photo taken by a shooting 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 an image on paper to produce a group photograph S.

As shown in FIG. 2, the group photography 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 a computer can be used, for example.

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 non-volatile memory, a hard disk device, and the like. The memory 12 stores a group photo editing program downloaded from a predetermined website by the communication unit 15 via the Internet.

When the CPU 11 executes the group photo editing program, as shown in FIG. 3, the face extraction unit 101, the print size determination unit 102, the cutout area determination unit 103, the text area determination unit 104, the character composition unit 105, and the print processing The function of the unit 106 is realized, and the captured image of the group photograph taken by the camera C can be edited.

The captured image data may be transferred from the photographing device C to the group photography device 10 via a wireless network, or the memory card in which the photographed image is written may be removed from the photography device C and the card slot of the group photography device 10 may be removed. It may be input to the group photography apparatus 10 by inserting it into.

The face extraction unit 101 extracts a person's face from the 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 extracted faces of the plurality of persons, and determines the print size of the group photo. For example, as shown in FIG. 4, the print size determination unit 102 detects the position of the face of the person F1 on the leftmost side in the image and the position of the face of the person F2 on the rightmost side in the image.

The print size determination unit 102 sets the ratio of the length d1 from the face of the person F1 to the left end of the image to 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. The ratio of is calculated, and the print size is determined based on these ratios. For example, when the ratio of the length d1 to the width W and / or the ratio of the length d2 to the width W is 10% or more, the print size is determined to be a 2L plate, and the ratio of the length d1 to the width W, And / or when the ratio of the length d2 to the width W is less than 10%, the print size is determined to be the 2Lw plate. That is, when the positions of the faces of the people on the left and right ends are close to the left and right ends of the image, a more horizontally long print paper is used. The threshold value of the ratio that determines the print size can be set arbitrarily.

The cutout area determination unit 103 determines the cutout 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 top or bottom of the image, and whether it is arranged at the top or bottom is preset.

For example, as shown in FIG. 5A, when the text area T is arranged at the lower part of the image, the cutout area determination unit 103 is the person F3 located at the uppermost part among the faces of the extracted plurality of persons. A face is detected, and a cutout line L1 is set at a position having a predetermined number of pixels above the position of the face. Further, the cutout area determination unit 103 sets the lower cutout line L2 from the position of the cutout line L1 and the print size. In the captured image, the area above the cutout line L1 and the area below the cutout line L2 (diagonal portion in the figure) are unprinted areas.

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

The text area determination 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 the 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 a predetermined number of pixels, a warning may be issued so that the height H of the text area T can be changed.

The character synthesizing unit 105 synthesizes the character information input via the input unit 14 into the text area. For example, as shown in FIG. 5B, character information is synthesized in the text area T. The font and size of the characters can be changed arbitrarily.

The print processing unit 106 cuts out the captured image along the cutout line, transfers the print image obtained by synthesizing the text information in the text area T to the printer P via the communication unit 15, and instructs the print size. The printer P prints an image for printing on a paper of a designated size and outputs the image. As a result, a group photograph S as shown in FIG. 5 (c) is produced.

As described above, the group photo editing device 10 according to the present embodiment determines a suitable print size from the position of the face of the person in the photographed image, and also determines the suitable print size according to the print size, and the faces of all the persons in the photographed image. Cut out the image so that it contains, and place the text area. Therefore, it is possible to reduce the workload of the group photo editing process by a cameraman or the like.

It is preferable that the group photo editing device 10 confirms that all the persons in the photographed image are captured from the top of the face to the bottom of the chin. When a person whose top of the head is not shown is included, the group photo editing device 10 may exclude this photographed image from the editing target.
