Description

[Technical field]

[0001] The present disclosure relates to a photography support device, a photography support method, and a program. [Background technology]

[0002] Conventionally, when a photographer takes pictures with family or friends, a countdown is displayed to get the person being photographed to time their pose, and the picture is taken while the person is maintaining the pose.

[0003] Non-Patent Document 1 describes how to use a stationary certificate photo machine that takes photos for various certificates. In order to improve the impression of the person being photographed in the photo, the person being photographed is forced to adjust the direction of his or her face by aligning his or her gaze with the camera installed at the back of the front before the photo is taken, and maintain a good appearance, facial expression, etc. for a certain period of time while looking at the image of his or her face reflected on the glass monitor in front.

[0004] [Non-Patent Document 1] "Certificate Photo Ki-Re-i", [online], [Retrieved May 21, 2021], Internet<URL:https: / / www.dnpphoto.jp / corp-customer / kirei / > Summary of the Invention [Problem to be solved by the invention]

[0005] As shown in FIG. 4, a conventional photography support device 10 that supports photography executes the following operations. A countdown signal generating unit 11 generates a countdown signal a and outputs it to a display control unit 12. The display control unit 12 outputs the content of the received countdown signal a, which is a number decremented at a certain time interval (for example, "5" → "4" → "3" → "2" → "1" → "0"), as display information b to a display device 14. When the display device 14 starts displaying the content of the countdown signal a, the person S to be photographed takes a determined pose. Then, when the countdown ends (the number becomes "0"), the countdown signal generating unit 11 outputs a photography execution signal c to the photographing device 15. When the photographing device 15 receives the photography execution signal c, it photographs the person S to be photographed.

[0006] However, with the conventional photography support device 10, a problem often occurs in that the person to be photographed loses his or her pose before the countdown ends, and an image of the person in the selected pose is not captured at the end of the countdown.

[0007] To solve the problem that the subject loses his / her pose before the countdown ends, and an image of the subject in the selected pose is not captured at the end of the countdown. [Means for solving the problem]

[0008] In order to solve the above problem, one embodiment of a photography support device is a photography support device that supports taking photographs, and includes a countdown signal generation unit that generates a countdown signal indicating a countdown number subtracted from a set value at regular time intervals, and a photography control unit that sends a photography execution signal to the photography device multiple times until the countdown number reaches 0.

[0009] In order to solve the above problem, one embodiment of a photography support method is a photography support method in a photography support device that supports photography, and includes a step of generating a countdown signal by the photography support device indicating a countdown number subtracted from a set value at regular time intervals, and a step of sending a photography execution signal to the photography device multiple times until the countdown number reaches 0.

[0010] In order to solve the above problem, a program according to one embodiment causes a computer to function as the photography support device. Effect of the Invention

[0011] According to the present invention, by photographing a pose taken by a person to be photographed before the pose is lost, it is possible to obtain an image of the determined pose even if the person to be photographed loses his / her pose before the countdown ends.

[Diagram 3] FIG. 2 is a block diagram showing a schematic configuration of a computer that functions as a photography support device. [Figure 4] FIG. 1 is a block diagram showing an example of the configuration of a conventional photography support device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, a photography support device according to an embodiment will be described in detail. The present invention is not limited to the following embodiment, and various modifications can be made within the scope of the present invention.

[0014] 1, a photographing support device 1 according to an embodiment includes a countdown signal generating unit 11, a display control unit 12, and a photographing control unit 13. The photographing support device 1 supports photographing a person S to be photographed.

[0015] The countdown signal generating unit 11 generates a signal (countdown signal a) indicating a countdown number that is decremented at regular time intervals from a set value set by the user (subject S), and outputs the signal to the display control unit 12 and the photography control unit 13. For example, when "5" is set as the set value, the countdown signal generating unit 11 generates and outputs countdown signal a indicating countdown numbers "4," "3," "2," and "1" that are decremented by 1 every second, and when the countdown number reaches "0" after 5 seconds, it stops outputting the countdown signal a. The user can set any value equal to or greater than 2 as the set value.

[0016] The display control unit 12 receives the countdown signal from the countdown signal generation unit 11, and generates countdown notification information b indicating the content of the countdown signal ("5", "0", etc.). If the countdown notification information b is an image, the display control unit 12 outputs the countdown notification information b to the display device 14, and if the countdown notification information b is audio, the display control unit 12 outputs the countdown notification information b to a speaker (not shown).

[0017] The display device 14 receives the countdown notification information b from the display control unit 12 and displays the countdown number. When the person S to be photographed visually confirms that the countdown number display has started, he or she takes a determined pose.

[0018] The photographing control unit 13 inputs the countdown signal a from the countdown signal generating unit 11. When the countdown signal a is input, the photographing control unit 13 transmits the photographing execution signal c to the photographing device 15 multiple times until the count number indicated by the countdown signal a becomes "0". The photographing control unit 13 may wait until the countdown number becomes equal to or less than a threshold before outputting the photographing execution signal c to the photographing device 15. The intervals between the photographing execution signals c do not have to be equal. For example, the photographing control unit 13 may output the photographing execution signal c to the photographing device 15 more times (narrow the intervals at which the photographing execution signal c is output) as the count number indicated by the countdown signal a approaches "0".

[0019] After receiving the countdown signal a, the photographing control unit 13 may start inputting the image information d photographed by the photographing device (camera) 15 and analyze the acquired image information d. For example, in order to perform photographing at a timing when motion blur is small, the photographing control unit 13 may determine that the image blur is decreasing when the low-frequency components of the acquired image information are decreasing, and output the photographing execution signal c to the photographing device 15 multiple times after the low-frequency components of the image become equal to or smaller than a threshold. Also, in order to avoid photographing with the eyes closed, for example, the photographing control unit 13 may determine that the eyes are open for several seconds after the eyes are closed, and output the photographing execution signal c to the photographing device 15 multiple times after the eyes are closed.

[0020] The photographing device (camera) 15 performs photographing of the person S to be photographed every time it receives a photographing execution signal c from the photographing control unit 13. That is, the photographing device 15 performs photographing even during the countdown.

[0021] Comparing the photographing support device 1 according to the embodiment with the conventional photographing support device 10, the photographing support device 1 is different in that the photographing support device 1 has a photographing control unit 13. In the photographing support device 10, the countdown signal generating unit 11 outputs a photographing execution signal c to the photographing device 15 only once when the countdown ends. In contrast, in the photographing support device 1, even during the countdown, the photographing control unit 13 outputs the photographing execution signal c to the photographing device 15 multiple times each time it receives the countdown signal a until it receives the countdown signal "0". Therefore, according to the photographing support device 1 according to the embodiment, even if the pose of the person S to be photographed breaks before the countdown ends, the pose taken before the person S breaks is photographed, so it is possible to acquire an image of the determined pose.

[0022] FIG. 2 is a flowchart showing an example of a photographing support method executed by the photographing support device 1 according to an embodiment.

[0023] In step S101, the countdown signal generating unit 11 generates a countdown signal a indicating a countdown number obtained by subtracting a countdown number from a set countdown number at regular time intervals, and outputs the signal to the display control unit 12 and the photography control unit 13.

[0024] In step S102, the display control unit 12 outputs the content of the countdown signal to the display device 14 as display information b.

[0025] In step S103, the monitor 14 displays the content of the countdown signal a.

[0026] In step S104, when the first countdown signal a is input, the photography control unit 13 transmits the photography execution signal c to the photography device 15 multiple times until the countdown number reaches zero.

[0027] In step S105, the photographing device 15 executes photographing of the person S to be photographed every time the photographing device 15 receives the photographing execution signal c from the photographing control unit 13.

[0028] As described above, the photographing support device 1 outputs the photographing execution signal c to the photographing device 15 multiple times from when the countdown signal is received until the count number reaches 0. Therefore, the photographing support device 1 can photograph the person S to be photographed even during the countdown. Therefore, even if the person S to be photographed breaks his / her pose during the countdown, it is possible to obtain an image of the person S before the break in pose.

[0029] Also, a computer capable of executing program instructions can be used to function the above-mentioned photographing support device 1.
