Description

  The present invention relates to a photography studio and a photography system for taking a human photograph, and in particular, a photography studio capable of seeing the inside of the studio from the outside and the influence of external light in the situation where external light exists. The present invention relates to a photographing system capable of photographing a person with a beautiful finish without any problems.

  Photography performed by a professional photographer in a photography studio represented by a photo studio is still a popular photography method among users who seek high-quality photographic images. It is also very important to prepare the studio shooting environment so that customers and models can be taken with vibrant and vivid facial expressions. In addition, it is a very important business strategy for managing a photo studio to have many people understand that photography in a photo studio is very attractive and to increase the number of customers visiting the studio. It becomes.

  However, many current photo studios have a structure that makes it difficult to satisfy them. In other words, many photo studios have a closed-room structure that cannot be seen from the outside, and even if there are many people passing by the photo studio, it is not possible to see how shooting is done inside It has become. In addition, the sealed environment of the studio often gives the subject a mental feeling of pressure, and some people feel uncomfortable because of the feeling of pressure. Sometimes it is filmed. This is inconvenient for both the photographer and the manager of the photo studio.

  From such a viewpoint, it is conceivable to provide a photo studio with a window that allows the inside of the studio to be seen from the outside, and there is also a technique that disposes a window in a room that can be used as a studio. (For example, refer to Patent Document 1) However, this document provides a window in a room that can be used as a dance studio, and does not suggest providing a window in a photo studio.

  In photo studios, in order to obtain high-quality photographic images, it is often the case that the lighting conditions at the time of shooting are set strictly, and there are documents relating to techniques for setting the lighting conditions at the time of shooting. For example, paying attention to the positional relationship between a subject and an illuminating means such as a strobe, a space for a photo studio is defined by three-dimensional coordinates, and the positions of the subject and light are set based on the three-dimensional coordinates (for example, Patent Documents) 2), and lighting conditions at the time of shooting are stored in a storage device together with image data shot by a shooting means such as a digital camera, and the optimum strobe conditions recorded from the storage device at the time of shooting are used. A technique for setting lighting conditions (for example, see Patent Document 3), and a box-type simple studio (for example, Patent Document 3) having a window that can be photographed from the outside and a light control means for controlling light emitted to the subject. 4)).

In this way, photography is performed with strict lighting conditions set in a photo studio, and if a window is provided in the photo studio, the lighting conditions are set so that the effect of external light enters the studio and the finish is good. It becomes very difficult. Therefore, it has not been done so far to provide a large window in the photo studio so that the inside can be seen.

  According to the present invention, it is possible to provide a portrait photograph with a good finish that is not affected by outside light, even if a window for entering outside light is provided in the photography studio. Since the situation can be seen from the outside, customers who are interested in full-scale photography in the studio have come to be able to touch the opportunity of photography at the photography studio. It has made it possible to dramatically increase the business opportunities for studio photography, including photo studios.

  In addition, since the airtightness of a conventional photography studio was eliminated, it became possible to shoot in a comfortable state without giving the subject a feeling of pressure, and captured a lively expression. The satisfaction of customers who took pictures was greatly increased.

The gallery G has an aim to make the gallery G want to take a photo at the photo studio 1.

  In addition, the purpose of the window 13 is to allow the subject H, who is unfamiliar with the shooting, to take a picture with a comfortable feeling without feeling nervous or squeezed by allowing the outside appearance to be seen from inside the studio. have.

  In the photography studio 1, an optimal lighting state that is not affected by outside light is formed, and a photographer such as a cameraman photographs the subject H by operating the camera. When the shutter of the camera is activated, the strobe light flashes in synchronization with this and the subject H is photographed.

  Next, a photographing system according to the present invention will be described. FIG. 2 is a block diagram showing a photographing system according to the present invention, which has the above-described photography studio 1.

  An imaging system 2 according to the present invention includes a camera 21 that is an imaging unit that captures an object H, and a strobe light 25 (25a to 25c that illuminates the object H when the camera 21 captures an image) And a control device (computer) 23 for controlling the operation of various devices used for photography in the photography studio 1, such as control of the amount of light emitted by the strobe light 25 during photography. It is comprised from the detection sensor 24 which detects the imaging environment in the photography studio 1 immediately before. Moreover, the window part 13 is provided in the wall part of the photography studio 1 as mentioned above, and the outside gallery G can see the inside of a studio here now.

  In the photographing system of FIG. 2, a main light 25a, a top light 25b, and a background light 25c are arranged, and these strobe lights are used as the above-mentioned illumination lights 11 and are used for strobe emission separately from the illumination lights. It is provided as a light. As shown in FIG. 2, the strobe light 25 is supplied with electric power from the strobe power source 27 and emits light in synchronization with the operation of the shutter of the camera 21.

  In the photographing system 2 according to the present invention, information on the external light in the photographing environment detected by the detection sensor 24 immediately before photographing is fed back to the control device 23 as an information signal. Specifically, the detection sensor 24 detects the shooting environment in synchronization with the moment the shutter of the camera 21 is pressed. That is, when the shutter of the camera 21 in FIG. 2 is pressed, a shutter signal SS is transmitted to the control device 23, and the detection sensor 24 can be operated via the control device 23.

  Here, the control device 23 controls the operation of various members constituting the photographing system 2 such as the light emission of the strobe light 25 and the operation of the camera 21 and the detection sensor 24, and is specifically a computer. The control device 23, which is a computer, includes a processing unit (CPU) 231 that actually performs control so that each device constituting the system operates smoothly, and a storage unit (main storage unit, auxiliary unit) that stores various types of information. (Storage unit) 232, an input unit for inputting information, and a display unit for displaying processing results and the like. In FIG. 2, the display unit and the input unit are omitted.

  In the present invention, as shown in FIG. 2, the photographing environment of the photography studio 1 is measured by the environment measurement unit 28 as a physical quantity such as illuminance, luminance, or color temperature. The detection information CS detected by the detection sensor 24 started by the shutter signal SS is measured. This is converted into information DS, and this measurement information DS is transmitted to the control device 23. The control device 23 compares the transmitted measurement information DS with the recorded information MS stored in the storage unit 232 of the device 23, performs processing such as computation on the recorded information, and the strobe light 25 eliminates the influence of external light. The amount of light emitted from the strobe light 25 is controlled by transmitting a power control signal PS instructed to emit light under the light emission conditions to the strobe power supply 27.

  Next, a method for detecting the photographing environment in the photography studio 1 according to the present invention will be specifically described. In the present invention, the shooting environment of the photographic studio 1 transmits detection information CS detected by the detection sensor 24 to the environment measurement unit 28 to convert the shooting environment into a physical quantity such as illuminance, luminance, or color temperature. In this way, the measurement information DS obtained by the measurement unit 28 is transmitted to the processing unit 231 of the control device 23.

  The processing unit 231 of the control device 23 collates the measurement signal DS, which is a measurement value in the shooting environment, with the recording information MS related to the shooting conditions stored in advance in the storage unit 232 such as the main memory, and if necessary, An arithmetic process is performed to calculate the amount of strobe light to be taken in a state where the influence of outside light is eliminated, and the amount of light of the strobe light 25 is controlled. Here, as information stored in advance in the storage unit 232, for example, information on the strobe emission amount corresponding to the brightness in the studio immediately before shooting, or the aperture value and shutter speed set in the camera 21 are supported. Information on the amount of stroboscopic light emitted, information on stroboscopic light emission corresponding to various shooting conditions, such as information on the light receiving element (CCD) performance in electronic cameras and information on stroboscopic luminescence corresponding to the sensitivity of the film used in a silver halide photographic camera It is done.

  Then, the control device 23 controls the amount of power from the strobe power supply 27 so that the strobe light 25 emits light determined as described above. At this time, the control device 23 transmits a power control signal PS to the strobe power supply 27 to control the strobe light 25 to emit strobe light as set.

  As described above, the photographing system 2 according to the present invention detects the illumination state including the influence of the external light in the studio 1 immediately before photographing, which is detected by the detection sensor 24, and feeds back the detection information to the control device 23 to provide a strobe. The light emission amount of the light 25 is adjusted so that photographing at a level that eliminates the influence of external light can be performed. Therefore, according to the photographing system 2 according to the present invention, even if there is external light in the studio, strobe light emission is performed with a light amount that eliminates the influence of the external light, thereby avoiding the occurrence of photographing defects due to the influence of the external light. In addition, it is possible to shoot under an appropriate amount of light.

  The detecting means used in the photographing system according to the present invention detects the amount of external light in the studio immediately before photographing. Here, the detection sensor 24 detects the amount of external light existing in the studio, but need not detect only the amount of external light, and is emitted from the illumination light 11 or the like existing in the studio. Needless to say, the light amount may be detected in a state including the light amount. Any device capable of detecting the amount of light in a state including external light may be used.

  Factors of the shooting environment that can be detected by the detection sensor 24 include luminous intensity / light flux, luminance, illuminance, color temperature, etc. in the studio immediately before shooting, and the detection sensor 24 performs shooting to detect these factors. Detects light information in the environment.

  Information on the light detected by the detection sensor 24 is analyzed via a measuring device (environment measuring unit 28) such as a luminance meter, a spectrocolorimeter, and an illuminometer, and the control device 23 is analyzed by these measuring devices 28. The obtained result is sent to the control device 23, and the control device 23 collates the measurement result with information relating to the strobe light emission condition corresponding to the above-mentioned photographing condition stored in advance in the storage unit in the control device 23, and at that time A strobe emission amount that cancels out the influence of external light in the shooting environment is determined, and the power supply amount to the strobe power source 27 is controlled.

  Note that the measurement device 28 that measures the information of the light detected by the detection sensor 24 is measured using, for example, an illuminometer and a spectrophotometer, a luminance meter and an illuminometer, and a luminance meter and a spectrocolorimeter. May be. As described above, by using a combination of a plurality of types of measuring devices, the accuracy of the measurement signal DS based on the detection information can be improved by the detection sensor 24, and light amount control with higher accuracy can be performed.

  The detection sensor 24 used in the present invention is not particularly limited as long as it can detect a shooting environment such as brightness and color temperature in the above-described photography studio 1. Specifically, a generally known photoelectric sensor is used, and an optical fiber type, an amplifier separation type, a built-in amplifier type photoelectric sensor, or the like is used.

  Specific examples of various detection sensors that can be used in the present invention include, for example, the homepage of OMRON Corporation (http://www.fa.omron.co.jp/sensing) and the homepage of KEYENCE Corporation (http: // // www.keyence.co.jp) listed in the catalog.

  The photographing system 2 according to the present invention detects the photographing environment in the studio 1 immediately before photographing, and feeds back the state of the photographing environment in which the influence of external light exists to the control device 23. The control device 23 is in the studio. The lighting conditions that cancel out the influence of external light are set immediately before shooting. That is, in the present invention, the influence of the external light in the shooting environment in the studio immediately before shooting is read, and the result is compared with the information recorded in the storage unit of the control device 23 so that the strobe does not cause the influence of the external light. By finding the light emission conditions and controlling the output of the strobe power supply so as to satisfy the light emission conditions, it is possible to obtain a portrait with good finish without the influence of external light.

  Next, a photographing procedure performed by the photographing system according to the present invention will be described. FIG. 3 is a flowchart of photographing in the photographing system according to the present invention.

  First, the layout of the shooting environment in the photo studio 1 is set. (Step S1). That is, various lighting devices are arranged in the photography studio 1, or a roll screen 12 as a background image is selected to perform layout setting.

  After setting the shooting environment layout, the shooting conditions of the camera 21 are set. (Step S2). In the present invention, the shooting conditions of the camera 21 include, as described above, the shutter speed and aperture value, and the sensitivity of the light-sensitive element (CCD) in the electronic camera and the film sensitive material in the silver halide camera. These photographing conditions set to 21 may be stored in the storage unit 232 of the control device 23 as camera signals.

  Next, the subject H is placed in the studio and the adjustment work immediately before shooting is performed. (Step S3). This is a state in which the strobe light 25 emits light synchronously when the shutter is pressed at the stage where the camera shooting conditions are adjusted again so that the subject H in the studio is shot with a good expression.

  When the cameraman presses the shutter of the camera 21 (step S4), a shutter signal is transmitted from the camera 21 to the control device 23, and the detection sensor 24 is activated. Then, based on the detection result of the detection sensor 24, it is determined whether or not shooting is performed in a state where the shooting environment in the photography studio 1 is not affected by outside light. (Step S5). Even at this stage, the set shooting environment and shooting conditions may be recorded in the storage unit of the control device 23. When the control device 23 determines that the strobe light can be emitted in the studio without the influence of the external light (Yes in step S5), the strobe light 25 is activated and photographing is performed. (Step S6).

  Further, when the control device 23 determines that a good-quality photograph cannot be taken due to the influence of external light existing in the shooting environment in the studio (No in step S5), the control device 23 is based on the information from the detection sensor 24. The light emission conditions are set so that the strobe light 25 emits the appropriate strobe light corresponding to the situation so as to offset the influence of the outside light in the studio. (Step S7). After the setting is made, it is confirmed whether or not the light emission of the strobe light 25 is a proper strobe light emission that cancels out the influence of the external light (step S5), and photographing under an appropriate exposure that cancels out the influence of the external light is performed. When it is determined that it can be performed (Yes in step S5), the strobe light 25 is activated and photographing is performed. (Step S6).

  Through the above steps, a person is photographed by the photographing system according to the present invention, and the photographing is finished. As described above, according to the present invention, by detecting the shooting environment immediately before shooting, by controlling the light emission amount of the strobe light 25 so as to perform exposure with the influence of external light offset, appropriate exposure conditions can be obtained. It makes it possible to perform portrait photography below.
