Description

  The present invention relates to a lighted shooting room that is mainly used in a photo studio and used for shooting a person.

  In general, when shooting a person with a camera in a photo studio such as a photo studio, lighting is necessary to ensure the illuminance of the person who is the subject. In many cases, a strobe that illuminates the light source is used as a main light source, and a stand that constantly illuminates a subject or part of the background is used as an auxiliary light source.

  When a strobe is used as the main light source, it is often placed near the camera, so even if the amount of light that can be illuminated to the desired illuminance can be projected on the person who is the subject, The amount of light that reaches may decrease, and the difference in the amount of light between the person and the background may increase. In general, silver halide film has a greater latitude than digital cameras, so even if the difference in the amount of light in the shooting range increases, so-called overexposure and blackout are unlikely to occur, and detailed information is captured in the image in the shooting range. However, digital cameras tend to reduce the amount of information in an image compared to silver salt film.

  In order to solve this type of problem, it is considered to use an auxiliary light source as described above, or to use an auxiliary strobe that emits light in synchronization with a strobe located near the camera. Therefore, the position and orientation of the auxiliary light source and strobe must be adjusted by trial and error, and this kind of writing work requires skill.

  By the way, a photography room equipped with a camera and illumination has been proposed in order to perform unmanned photography of a person as a subject (see, for example, Patent Document 1).

Patent Document 1 describes that a plurality of cameras are installed so that shooting can be performed at various angles, and strobes that are key lights and fill lights are arranged, and backlights and effect lights are also provided. It is described that a strobe may be arranged. That is, in the technique described in Patent Document 1, a plurality of strobes are used.
JP 2000-81652 A

  If a plurality of strobes are used in combination as in the technique described in Patent Document 1, it is possible to suppress uneven illuminance within the shooting range of the camera, but it is difficult to adjust the position and orientation as described above. Have a problem. In addition, an image of about 1,500,000 pixels as described in Patent Document 1 does not need to be printed in a large format, so the amount of information in the image may be small. In the case of an image that exceeds pixels and it is necessary to capture information in detail to print a large-sized photograph, expert knowledge is required for the strobe placement.

  The present invention has been made in view of the above-mentioned reasons, and its object is to provide an illuminated shooting room capable of properly illuminating a person who is a subject without special knowledge. is there.

  According to the first aspect of the present invention, the inside of the photographing room main body is steadily and generally fixed in a box-like photographing room main body in which a person to be a subject enters, and the ceiling surface and both side walls of the photographing room main body. It is characterized by comprising a plurality of illuminating lighting fixtures for illuminating and a light amount adjuster for changing the amount of light emitted from the photographic lighting fixtures.

  According to a second aspect of the present invention, in the first aspect of the invention, a plurality of rows are arranged in the front-rear direction on the ceiling surface and both side wall surfaces, and the light amount adjuster is provided for each photographing illuminator. The amount of emitted light for each is variable.

  According to a third aspect of the present invention, in the second aspect of the present invention, the light amount adjuster is configured so that the difference between the illuminance of the person who is the subject and the illuminance of the rear wall of the photographing room main body is not more than a specified value. It is characterized by adjusting the amount of light emitted from the lighting equipment for lighting.

  According to a fourth aspect of the present invention, in any one of the first to third aspects of the present invention, the auxiliary for illuminating the front surface of the person who is the subject on the floor surface of the photographing room main body with an obliquely upward beam. A lighting fixture is embedded and arranged.

  According to a fifth aspect of the present invention, the projector according to any one of the first to fourth aspects, further comprising: a projection screen disposed on the rear wall of the photographing room main body; and a projector that projects an image from the back onto the screen. It is characterized by.

  According to the configuration of the first aspect of the present invention, the difference in illuminance in the internal space of the photographing room main body is reduced by illuminating from the ceiling surface and the both side wall surfaces using the photographing illuminator that performs general general illumination. Can do. In other words, the difference in illuminance between the subject person and the background is small, and even when using a digital camera with low latitude, whiteout and blackout are unlikely to occur, and information within the shooting range is captured in the image in every detail. There is an advantage that becomes possible. In other words, there is an advantage that a beautiful photograph can be output even if printing is performed in a large format. In addition, since the light amount adjuster is provided and the emitted light amount of the illuminating lighting apparatus is variable, there is an advantage that the illuminance can be adjusted to be suitable for photographing a person as a subject.

  According to the configuration of the invention of claim 2, a plurality of illuminating lighting fixtures are arranged in the front-rear direction on the ceiling surface and both side wall surfaces, and the amount of light emitted from each photographic lighting fixture is variable. It is easy to adjust the illuminance, and it is easy to adjust the quantity of emitted light to reduce the difference in illuminance between the subject person and the background.

  According to the configuration of the invention of claim 3, the light quantity adjuster adjusts the emitted light quantity of the illuminating lighting apparatus in conjunction with each other, and the difference between the illuminance of the person who is the subject and the illuminance of the rear wall of the photographing room body which is the background Since the illuminance of the person who is the subject is adjusted to an illuminance suitable for shooting, the illuminance of the rear wall of the shooting room is automatically determined, and the appropriate illuminance is not required. There is an advantage that it becomes possible to shoot with.

  According to the configuration of the invention of claim 4, since the person is illuminated with the light bundle obliquely upward using the auxiliary lighting device, the front side of the person to be photographed can be illuminated brightly. In particular, if an auxiliary lighting device is used to illuminate the vicinity of the face, the face of the person can be illuminated brightly. There is an advantage that the face, which is the most important part when shooting in a photo studio or the like, can be beautifully shot.

  According to the configuration of the fifth aspect of the invention, since an image is projected from the back onto a screen provided behind the person who is the subject, an arbitrary background can be created by selecting the image to be projected. In other words, in order to create a background scene, a large-format photo or background image was used in the past. By adopting the configuration for projecting the image, there is an advantage that the background can be easily changed at low cost. Also, by using a projection screen, the background of the person who is the subject becomes reasonably bright, so it is easy to equalize the illuminance between the subject and the background, and when illuminating with a large amount of light instantaneously like a strobe The image projected on the screen is masked so that it cannot be reflected in the image. On the other hand, because the illuminating lighting equipment that illuminates constantly is used, the image on the screen is photographed in the same way as seen with the eyes. can do.

  Hereinafter, an illuminated photographing room according to the present invention will be described with reference to FIGS. The photographing room main body 1 used in the present embodiment is assumed to be installed in a photo studio such as a photo studio, and is formed in a box shape with an open front. Here, the front surface of the photographing room main body 1 means the side where the camera 6 for photographing the subject as viewed from the photographing room main body 1 is installed. That is, the front of the subject when the subject entering the photographing room main body 1 faces the camera 6 is also referred to as the front of the photographing room main body 1.

  The floor surface 11 of the photographing room body 1 is stepped with a step from the floor surface of the photo studio. The person is photographed by the camera 6 installed on the floor of the photo studio. Therefore, by raising the person who is the subject to the floor surface 11 that is one step higher than the floor surface of the photo studio, it is possible to give the person the impression that he / she has gone up on the stage and to raise his / her mood and perform the subject.

  The illuminating lighting device 2 is embedded in the ceiling surface 12 and the side wall surfaces 13a and 13b of the photographic room body 1 respectively. The photographic lighting fixture 2 is a lighting fixture in which a straight tube fluorescent lamp 21 having high color rendering properties is housed in a fixture main body 20, and the fixture main body 20 has a translucent panel 22 having a diffuse transmission property covering the emission surface. Has been placed. In addition, a plurality of (for example, three) fluorescent lamps 21 are accommodated in the instrument body 20. The fluorescent lamps 21 housed in one appliance body 20 are arranged so as to be aligned in the front-rear direction of the photographing room body 1. That is, the longitudinal direction of the fluorescent lamp 21 coincides with the left-right direction of the photographing room body 1 in the photographing illumination fixture 2 arranged on the ceiling surface 12, and the fluorescent lamp in the photographing illumination fixture 2 arranged on the side wall surfaces 13a and 13b. The longitudinal direction of 21 coincides with the vertical direction of the photographing room body 1. Further, in the present embodiment, a plurality of rows of illuminating lighting fixtures 2 are arranged in the front-rear direction on the ceiling surface 11 and the side wall surfaces 13a and 13b, respectively.

  In the present embodiment, the auxiliary lighting device 3 is embedded in the front portion of the floor surface 11 of the photographing room main body 1. The auxiliary lighting fixture 3 is a lighting fixture in which a straight-tube fluorescent lamp 31 having high color rendering properties is housed in the fixture main body 30 in the same manner as the photographing lighting fixture 2, and the fixture main body 30 has diffuse permeability covering the emission surface. A translucent panel 32 is disposed. However, while the lighting fixture 2 is controlled to distribute light so that light can spread throughout the room of the photographing room body 1, the auxiliary lighting fixture 3 is directed from the floor to the subject. Light distribution control is performed so that the light beam is emitted obliquely upward. That is, the inner surface of the instrument body 30 is formed in a V-shaped cross section in which the lower ends of the slope that rises and inclines toward the rear of the photographing room body 1 and the slope that rises and inclines toward the front are coupled to each other. The rising slope is a mirror 33, and the fluorescent lamp 31 is disposed between both slopes. Therefore, the light emitted from the auxiliary lighting device 3 irradiates the subject in the photographing room main body 1 with an obliquely upward light beam.

  By the way, the photographing illumination fixture 2 and the auxiliary illumination fixture 3 illuminate the internal space of the photographing room body 1 steadily, and a light amount adjuster 4 is connected to adjust the emitted light amount. The light amount adjuster 4 individually changes the amount of light emitted from the photographing lighting device 2 and the auxiliary lighting device 3, and adjusts the power supplied to the fluorescent lamps 21 and 31 of the photographing lighting device 2 and the auxiliary lighting device 3. Dimming. Here, it is desirable that the photographing lighting fixture 2 and the auxiliary lighting fixture 3 use an inverter type lighting circuit, and the dimming of the fluorescent lamps 21 and 31 is realized by controlling the operation of the lighting circuit. The translucent panels 22 and 32 are arranged so as to be flush with the inner peripheral surface of the photographing room main body 1 so that the photographing lighting equipment 2 and the auxiliary lighting equipment 3 do not protrude into the internal space of the photographing room main body 1.

  The light amount adjuster 4 is provided with an illumination operation unit 41 that can be operated by a photographer who takes an image of the subject with the camera 6. The illumination operation unit 41 can adjust the amount of light emitted from each of the lighting fixtures 2 and auxiliary lighting fixtures 3 and can also adjust the amount of emitted light in conjunction with the whole lighting fixture 2 for shooting. ing. In the illustrated example, three lighting fixtures 2 are arranged on the ceiling surface 12 and both side wall surfaces 13a and 13b, respectively, and two auxiliary lighting fixtures 3 are arranged on the floor surface 11. In the unit 41, the emitted light amount is individually adjusted for the nine photographing lighting devices 2, and the emitted light amount is individually adjusted for the two auxiliary lighting devices 3. Therefore, without changing the position or orientation of the illumination light source, the photographer simply operates the illumination operation unit 41 so as to determine the amount of light emitted from each photographing illumination device 2 and each auxiliary lighting device 3. It becomes possible to illuminate the interior space of the room body 1 with an illuminance suitable for photographing.

  Further, the lighting operation unit 41 has the nine shooting lighting fixtures 2 so that the difference between the illuminance of the person who is the subject and the illuminance of the rear wall 14 of the photographing room main body 1 becomes a predetermined value or less. It also has a function of adjusting the amount of light emitted from the lighting fixture 2 in conjunction with it. For this operation, the light amount adjuster 4 is provided with a light amount data table 42 in which the correspondence relationship between the emitted light amounts of the respective photographing illumination fixtures 2 is set. In this case, by referring to the light amount data table 42, the amount of light emitted from each lighting fixture 2 is determined. Therefore, when the amount of light emitted from the photographic illumination fixture 2 is determined so that a desired illuminance can be obtained for the subject, the illuminance of the rear wall 14 is automatically determined appropriately. In other words, by keeping the illuminance difference between the subject and the background below the specified value, even when the latitude is small like a digital camera, detailed information about the subject and the background can be obtained without causing overexposure or underexposure. It is possible to take a picture with it.

  By the way, in the present embodiment, a projection screen 51 is disposed on the rear wall 14 of the photographing room main body 1. The screen 51 is a transmission type, and the projected image can be seen from the front by projecting from the back. The screen 51 has a sufficient size (for example, 2 m width × 1.8 m height) to allow a background image to be projected when the subject person is photographed by the camera 6. In addition, it is desirable that the rear wall 14 excluding the screen 51 in the photographing room main body 1 is composed of a glossy milky white diffuse reflective panel. By using such a panel, it is possible to prevent the photographing lighting device 2 and the auxiliary lighting device 3 from being reflected on the rear wall 14. Further, the lower end portion of the rear wall 14 is curved so as to be smoothly continuous with the floor surface 11.

  The projector 52 that projects an image from the back on the screen 51 is disposed at the lower part of the photographing room body 1, and the image projected from the projector 52 is repeatedly reflected using a plurality of (three in the illustrated example) mirrors 53. After that, it is projected on the screen 51. The image of the projector 52 is usually a still image, and an image created by a computer, a photographed image, or the like can be used. For example, by using an image recording device 50 in which a plurality of actual images are recorded on a storage device of a computer or a DVD, an appropriate image is read from the image recording device 50 and given to the projector 52, thereby projecting this image on the screen 51. Can do. Whether or not to project an image on the screen 51 and which image to project can be selected by the image operation unit 53 arranged at the hand of the photographer who operates the camera 6.

  As described above, the illumination operation unit 41 and the image operation unit 53 are arranged at the hand of the photographer, and by adjusting the distribution of the amount of light inside the photographing room main body 1, appropriate illumination is performed without requiring special skills. The amount of light can be adjusted in this way, and by appropriately changing the background, shooting in various scenes can be easily performed. In addition, since the illumination that constantly projects light is used instead of the illumination that flashes instantaneously like a strobe, if the brightness projected on the screen 51 is adjusted in advance, the screen 51 can be clearly displayed. It is possible to display a simple image and take the image with the camera 6. In other words, the image light projected on the screen 51 is not masked by the light from the image light illumination device 2 or the auxiliary light light device 3, and the image light projected on the screen 51 is not backlit. The relative relationship between the light quantity of the lighting fixture 3 and the light quantity of the projector 52 is set.

  In the above-described example, it is assumed that the camera 6 is installed on the floor surface of the photography studio, but the camera 6 is installed on the floor surface 11 of the photographing room body 1 or the camera 6 is photographed by hand. In the above-described example, the box-shaped photographing room main body 1 whose front surface is opened is used. However, the photographing room main body 1 that is a closed space without forming an opening may be used.

It is a perspective view which shows the external appearance of embodiment. It is sectional drawing same as the above. It is a block block diagram same as the above.
