have. On the liquid crystal monitor 32, an image from the camera unit 31 during shooting and an image during image playback are displayed. The above digital camera 30 has an automatic focusing
The focus and the color balance are automatically determined by an automatic exposure mechanism or the like, and it is designed so that anyone can take a picture, taking into account that the picture can be taken without fail both indoors and outdoors. Further, fixing screws 34 and 35 similar to the fixing screw 33 are provided on the vertical portion 36 on the left side and the upper part on the rear side.
4, as shown by a dashed line in FIG.
With the tripod attached and the fixed base 24 removed,
It is used when photographing the inside of the box 1 from the front opening 2. By using such a digital camera 30 on the upper surface of the portable box 1 as described above, anyone can use any product (for example,
Bags, boxes and matte or polished surfaces using surface materials such as vinyl, plastic, paper, etc.)
However, a well-balanced good photographing result can be easily obtained in a short time, that is, a good image without uniform color correction can be easily photographed. In addition, box 1
It has a moderate size that makes it easy to carry and move, etc., and blocks the external light to make the inside white (because the inner surface is white), thereby increasing the bounce effect of light and It is designed so that the shape of the product photographed using light looks natural. Next, a method of photographing a product by the photographing assistance device having the above configuration will be described. First, a commodity (not shown), which is an object to be photographed, is placed on a photographing object receiving plate 9 along a center line and a grid line (not shown) drawn on the upper surface thereof, and the opening and closing doors 3, 3 are closed. , The center of the screen of the liquid crystal monitor 32 projected by the camera unit 31 of the digital camera 30 from above is designed to automatically appear. Thereafter, the photographer operates the up / down switch 23 on the front right side of the upper surface of the box 1 in accordance with the display of the vertical movement direction while viewing the screen of the liquid crystal monitor 32 from the front side of the box 1, and drives the electric motor 20. The vertical moving bed 15 is moved up and down through the engagement of the driving gear 21-3 and the feed screw 18 by the
The object receiving plate 9 on which the product is placed is moved up and down until the screen becomes an appropriate size. At this time, the power switch 22-arranged in line with the elevation switch 23 on the front right side of the upper surface of the box 1.
1 is turned on to turn on the fluorescent lamps 8-1 and 8-1 to illuminate the product. With respect to this illumination, the product is illuminated obliquely rearward at an angle of 45 ° to the left by two fluorescent lamps 8-1 and 8-1 having a color temperature of 4,200 ° K. The positional relationship was designed so that the lightness could be maintained from the close-up photography to the standard (in the case of products, from screws to pet food) so that the "blur", "tekari" and "color skipping" would not occur due to the irregular reflection of light. It is. Since the digital camera 30 automatically adjusts the color balance and the exposure amount at the ratio indicated by the photographing area of the subject, there is a possibility that the subject will vary, and the color reproduction and the exposure amount will be different. By operating the pair of right and left light shielding plates 27, 27 built in the fixed base 24 with the light shielding plate operation knobs 28, 28 for manual operation to narrow or open the photographing range, the liquid crystal monitor 3 is opened.
Adjust the white color in the screen while looking at the screen 2 to make the color closer to the product. For example, when a pure white product is placed on the black object receiving plate 9, the white is strongly raised, so the light shielding plates 27, 27 are closed to narrow the image capturing range to increase the white image capturing range. In addition, when the fixing base 24 is rotated by 90 ° and attached to the fixing base mounting hole 6 of the top plate of the box 1, the longitudinal direction of the photographing hole 25 facing the camera unit 31 of the digital camera 30 on the fixing base 24 and , The longitudinal direction of the object receiving plate 9 in the box 1 matches the longitudinal direction, and the image can be projected on the screen of the LCD monitor 32 in accordance with the long product.
For example, it is designed to be able to handle things with a length of about 700 mm, such as dog hoods for dogs. As described above, in order to photograph a product such as a bottle or a transparent plastic bottle, it is necessary to lay the transparent plastic bottle on its side in order to clarify the product name and shape. In this case, air bubbles are generated by air contained in the transparent plastic bottle, resulting in a photograph lacking in beauty. For this reason, an image is taken from the front opening 2 of the photographing assist device while the transparent plastic bottle stands on the photographing object receiving plate 9. In this case, the fixing stand 24 is removed from the photographing assist device and the digital camera 30 is moved to the fixing stand 24. Fixing screw 3 provided on the vertical portion 36
4 and further, a tripod is attached to the fixing screw 35 so that the digital camera can be fixed.
Try to shoot from. As described above, by using the fixing stand 24, the digital camera 30 can be fixed, and as described above, the color adjustment by the light shielding plates 27 can be performed. In this case, the power switch 22-1
Is operated to turn on the fluorescent lamps 8-1 and 8-1, and the power switch 22-2 is operated to turn on the fluorescent lamp 8-2. This makes the light of the fluorescent lamps 8-1 and 8-1 on the left back side wrap around the inside of the transparent plastic bottle to make the color inside the product look beautiful, and shoot a more clear and close to real shooting. This is to make it possible. Also, the fluorescent lamp 8 on the left front side
The light of -2 illuminates the product from the front to sharpen the outline of the product and make the product stand out, and also makes the product label etc. look beautiful, so that the front of the product can be photographed closer to the real thing. That's why.
Therefore, when photographing a transparent plastic bottle, the fluorescent light 8
By turning on -1, 8-1, 8-2, it is possible to take a picture closer to the real thing. As described above, the following effects can be obtained by using the photographing assistance device according to the embodiment of the present invention. (1) By providing the manual milky white plastic light shielding plates 27 and 27 on the fixed base 24 of the digital camera 30, even a person who has not mastered the photographic technique can control the amount of light entering the lens unit 31 by using the liquid crystal monitor 32. The optimal image can be determined while looking at the screen. (2) By seeing the product inside the box 1 from the viewing window 7 in front of the fixing stand 24 on the upper surface of the box 1, it is possible to easily compare the product on the screen of the liquid crystal monitor 32. (3) By setting the fixing stand 24 of the digital camera 30 to be a square in a plan view, the position of the fixing stand 24 with respect to the upper surface of the box 1 is rotated by 90 °, so that the relationship between the vertical position and the horizontal position with respect to the product as the subject is changed. Alternatively, an image can be optimally displayed according to the screen of the liquid crystal monitor 32. (4) Since the vertical movement bed 15 is positioned on one side of the object receiving plate 9, the product to be mounted on the object receiving plate 9 and photographed is about 20 mm.
It is possible to use from a screw of about a degree to pet food for a dog of about 700 mm. Also, by setting the moving speed of the up-and-down moving bed 15 to about 10 mm for 1 second, it can be loaded up to a maximum weight of 60 kg and can correspond to most products. be able to. (5) With respect to lighting, two fluorescent lamps 8, 8 having a color temperature of 4,200 ° K and a power of 20 W are installed at a position from the upper left 45 ° in the box body 1 so that the plastic bottles which are easy to fly color are provided. Also, the bag and the neutral color plastic container were able to obtain the correct color and brightness without adjustment. (6) Sufficient photographing results could be obtained even for those who are new to photographing. In addition, the shooting time was very short. As a result, photographing was completed at a cost of 1/10 to 1/20. Next, a modified example of the embodiment of the present invention will be briefly described. First, according to the above-described configuration, the posture of a product placed on the object receiving plate 9 in the box body 1 is changed each time, and the digital camera 30 (camera unit 31) located above is changed.
The front, side, and top are photographed. As a first modified example, for example, a reflection device using a reflection mirror or the like is provided in the box 1, and the front, side, and top of the product are photographed in one shot. 3
You may comprise so that a surface may be image | photographed simultaneously. In the embodiment described above,
As the distance adjusting means for adjusting the distance between the digital camera 30 (camera unit 31) and the product in the box 1, the mounting position of the object receiving plate 9 with respect to the elevating device 10 and its vertically movable bed 15 is changed. However, as a second modified example, on the contrary, a distance adjusting unit that enables the digital camera 30 or its camera unit 31 to be movable with respect to the product in the box 1 may be used. Further, as a third modified example, the digital camera 30 may be installed on the upper surface, the front surface, and the side surface of the box 1, and the image of each surface may be photographed by a switch operation. As a fourth modification, the manual light shielding plates 27, 27 may be provided on the box 1 side. In the embodiment described above, the elevating device 10 is configured such that the electric motor 20 is fixed and the vertically moving bed 1 is fixed.
5 was moved, but as a fifth modified example, an electric motor, a gear box, a vertically moving bed, and a plate holding arm may be integrated, and this integrated thing may be vertically moved. Good. Specifically, as shown in FIG. 9 (here, the same parts as those shown in FIGS. 4 to 6 are denoted by the same reference numerals and described), the electric motor 20, the gear box 19, The vertical movement member 37 is formed integrally.
And, between the lower fixing plate 11 and the upper fixing plate (not shown), and at both ends of the fixing plates, the columns 13, 1
