Abstract

PROBLEM TO BE SOLVED: To prepare life-size photographs of suckling babies or the like easily and accurately.SOLUTION: A photograph is prepared by performing a step of fixing a digital camera 100 directed vertically downward; a step of arranging a suckling baby 200, who is to be photographed, right underneath the digital camera 100; a first shooting step of photographing the suckling baby 200 alone; a second shooting step of photographing the suckling baby 200 together with a scale body 150 of a known size; a step of figuring out the magnifications to express, on the basis of the image acquired at the second shooting step, the scale body 150 in its real size when the image is outputted as printed matter; and a step of outputting as printed matter in accordance with the figured-out magnifications the image obtained at the first shooting step.

Description

  The present invention relates to a photo creation method, and more particularly, to a method for creating a life-size photo easily and accurately for a subject such as an infant.

  2. Description of the Related Art Conventionally, it has been widely practiced to take a picture of an infant and print it approximately in life (Non-Patent Document 1).

  However, the technique in Non-Patent Document 1 has been made a life-size by a fairly appropriate technique such as printing a photographed baby to life-size “about” with a rough eye measurement. It cannot be said that it has been reproduced. In particular, parents with children have a desire to leave their children at the actual size of the photo at the time of shooting, but still have not been realized.

  Accordingly, the present invention has an object to create a life-size photograph of an infant or the like simply and accurately in order to satisfy such a demand.

  In order to solve the above-mentioned problems, the present invention provides a step of fixing a digital camera vertically downward, a step of placing a subject in a position directly below the digital camera, and a first photographing of the subject alone. Based on the imaging process, a second imaging process for imaging the subject together with a scale body of a known size, and the scale obtained when the image is output as a printed material based on the image acquired in the second imaging process. The method includes a step of obtaining a magnification at which the body is an actual size, and a step of outputting the image acquired in the first photographing step as a printed matter according to the obtained magnification.

  By creating a photo (printed material) through such a procedure, it is possible to easily create a photo that accurately reproduces the size of a subject such as an infant.

  In addition, it is desirable that the scale body be arranged and photographed so that the reference plane is horizontal.

  As a result, dimensional errors caused by scale inclination and the like can be eliminated.

  In addition, when the subject is an infant, it is preferable that the scale body is placed and photographed at the forehead position of the infant.

  When an infant, who is the subject, is laid on the floor, there is an error in the size of the photograph depending on which height is the reference because there is a thickness in the height direction. For example, it is possible to reproduce the size of the most eye-catching face part in a photograph of an infant as a photograph in a life-size manner without any inaccuracy.

  Also, a scale body used in the above method, wherein a reference surface portion having a known size, a main body portion that supports the reference surface portion, and a positioning that allows the reference surface portion to slide up and down relative to the main body portion. And a level that can measure a horizontal state of the reference surface portion.

  By using such a scale body, it is possible to shoot with a reference plane placed on a desired part (forehead, chest, navel, etc.) of a subject (for example, an infant in a laid state).

  By applying the present invention, a life-size photograph of a subject such as an infant can be created easily and accurately.

It is the schematic which showed arrangement | positioning etc. of the digital camera at the time of imaging | photography, a to-be-photographed object (baby). It is the figure which showed the state which has applied the scale body to the to-be-photographed object (baby). It is a perspective view of a scale body.

  Hereinafter, with reference to the accompanying drawings, a description will be given of a photo creation method which is an example of an embodiment of the present invention. For easy understanding of the drawings, it should be noted that there are portions where the size and dimensions of each portion are exaggerated and there are portions that do not necessarily match the actual product. In addition, each drawing is viewed in the direction of the reference sign, and is expressed as upper, lower, left, right, near, and back based on the direction.

<Photo creation procedure>
First, the digital camera 100 is fixed using a tripod 102 or the like so that the lens direction of the digital camera 100 is directed vertically downward.

  Subsequently, the infant 200 to be a subject is laid down at a position directly below the lens of the digital camera 100.

  On the other hand, the focal length of the lens is fixed at an appropriate position. The focal length at this time is set to 50 mm or more in order to prevent a photograph taken due to the difference between the front and rear of the infant as a subject (the difference in the height direction when the infant is laid down) from being a perspective. Is desirable. Also, the fixed focal length is not changed until shooting is completed.

  Subsequently, the baby 200 is photographed alone (first photographing process).

  Subsequently, as shown in FIG. 2, the infant 200 is photographed together with the scale body 150 (second photographing step). Specifically, the reference surface portion 158 of the scale body 150 is placed on the forehead of the infant 200, and further, it is confirmed by the level 160 that the reference surface portion 158 is horizontal, and then the scale body 150 (the reference of the scale body 150). The surface portion 158) is also photographed together. Ideally, the reference surface portion 158 should be arranged so as to come into contact with the forehead of the infant 200, but if the reference surface moves due to movement of the infant, the reference surface portion 158 may be arranged so as to float slightly. . The scale body 150 can be positioned by sliding the reference surface portion 158 up and down relative to the main body portion 154, a reference surface portion 158 created using a ruler, a main body portion 154 that supports the reference surface portion 158, and the main body portion 154. A positioning mechanism 156 and a level 160 that can measure the horizontal state of the reference surface portion 158 are provided (see FIG. 3).

  Note that the order of the first photographing step and the second photographing step may be reversed.

  Subsequently, based on the image acquired in the second photographing step, a magnification at which the scale body 150 (the reference surface portion 158) becomes an actual size when the image is output as a printed matter is obtained. Specifically, after the image is read using commercially available image processing software or the like, a magnification at which the size of the scale body 150 (the reference surface portion 158) is printed is acquired. Since the reference surface portion 158 is constituted by a ruler, the magnification at which the scale (for example, 10 cm) of the ruler is actually 10 cm is obtained.

  Next, an accurate life-size photograph of the infant 200 is completed by converting the image obtained in the first photographing step to the magnification obtained in the previous procedure (replacement of the image) and printing.

  Note that color correction and the like can be freely performed as necessary.

  As described above, according to the creation method of the present invention, a life-size photograph of an infant can be created easily and accurately. In particular, when the infant 200 as a subject is placed on the floor, there is an error in the size when the photograph is taken depending on which height is the reference because there is a thickness in the height direction. As a reference, it is possible to reproduce the size of the most eye-catching face part in a photograph of the infant 200 as a photograph in a life-size manner without any inaccuracy.

  In the above description, an infant is taken as an example of the subject. However, the present invention can be widely applied to infants, children, and adults. Furthermore, it is possible to create a photograph by focusing on only a specific part of the body and making only the specific part life-size. For example, it is effective when you want to create a life-size photo of a specific muscle that has been trained, such as a body builder, and leave it in memory as a memorial. This is also effective when you want to compare them.
