Description

  The present invention relates to a photographing system in which a person having advanced photographing techniques such as a photographer uses a studio to create a portrait and other portraits, particularly when photographing is performed. The present invention relates to a photographing system capable of appropriately changing the setting of exposure conditions of a strobe according to the situation.

  Photography using a photographer in a photo studio or a photo studio is one of the popular photography methods among ordinary users as a method for obtaining a portrait photograph with a lively and beautiful finish. Lighting conditions such as strobe lighting at the time of shooting are very important factors in obtaining high-quality photographic images, and there is a technology for shooting under the optimal lighting conditions for the subject. Various studies have been conducted so far.

For example, focusing on the positional relationship between a subject and a lighting unit such as a strobe, a technique is disclosed in which the space of 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, refer to Patent Document 1.)
In addition, in order to facilitate lighting in strobe shooting in the studio, lighting conditions at the time of shooting are stored in a storage device together with image data shot by shooting means such as a digital camera, and stored in a storage device when taking a picture. Also disclosed is a technique for making optimal lighting settings by utilizing recorded strobe conditions. (For example, see Patent Document 2.)
In this way, although the technology for obtaining high-quality photographic images by setting the lighting at the time of shooting to an appropriate condition is disclosed, a beautifully finished portrait photograph that faithfully reproduces the photographer's facial expression is stable These techniques alone were not sufficient to achieve this.

For example, the technique disclosed in Patent Document 1 relates to a lighting condition for taking a product photograph to be published in a catalog or the like, and illumination for taking a beautiful article can be applied to a lighting condition for taking a human photograph. is not. In other words, when shooting a person, it is necessary to set the lighting conditions taking into account the movement of the subject and changes in facial expression, and taking a human photograph with a lively expression by applying the lighting technology when shooting a stationary object It ’s difficult. Therefore, Patent Document 1 that does not describe writing when taking a human photograph does not suggest any writing technique to be performed when taking a human photograph.

  In addition, as in Patent Document 2, it is difficult to think that a photograph with a satisfactory finish can be obtained even if the lighting conditions obtained in the past are used. For example, if the photographer's clothes, skin, and hair color are slightly different from the sample photograph, the photograph of the target finish cannot be obtained unless the lighting conditions are changed slightly. In addition, strobes used for photographing often have subtle changes in light emission due to changes in color temperature depending on conditions such as the number of uses. Therefore, although the lighting conditions obtained at the time of past shooting are only a reference level for setting conditions, it is considered that the lighting conditions cannot be used as they are to reproduce accurate strobe light emission.

  Also, in full-scale photography using a photo studio or studio, customers may be concentrated at specific times, such as Shichigosan or graduation season. In such a situation, it is required to take an efficient photograph so that a satisfactory finished photo can be obtained without waiting for the customer as much as possible, but the lighting conditions for each customer are enormous. Finding and setting up a large amount of databases is not a realistic response from a time perspective.

In this way, a shooting system that can change the lighting conditions according to the situation and take a picture has not been constructed so far, and it is a finish that will satisfy the users in the photo studios and photo studios in the city. It was difficult to provide beautiful portrait photos.

  The present invention relates to a photographing system for photographing a person by a person having advanced photographing techniques such as a cameraman, and in particular, the photographing state in a studio is detected immediately before photographing, and the detection result is used for the amount of light emitted from a strobe. The present invention relates to a photographing system capable of automatically setting the best lighting environment in accordance with a state at the time of photographing by feeding back to a control device to be controlled.

  Hereinafter, the present invention will be described in detail.

  First, shooting in a photo studio will be described. In a photography studio, an optimal lighting state is set for a subject according to the purpose of photography, and then shooting is performed by flashing a strobe light in synchronization with a camera as a photographing means. FIG. 1 is an image diagram showing a photographing state in a photography studio in which the photographing system according to the present invention can be used.

  In the photography studio 1, various lights 11 (11a to 11e) as illumination means are arranged around the subject H as shown in FIG. Specific lights used for photography include lighting devices such as a front light, a main light, a background light, an accent light, a top light, and a sky light. Moreover, the photography studio 1 of FIG. 1 has the roll screen 12 used as a background behind, and the roll screen 12 hangs up and down according to a condition.

  In the photography studio 1 shown in FIG. 1, the subject H is photographed by changing the positions of these lights and their outputs (dimming) with the roll screen 12 as the background. In general, the various lights 11 are appropriately selected according to the purpose of shooting and used for shooting. Moreover, a lamp for strobe light emission is provided in these lights, and it can be used as a strobe light.

  In the photography studio 1, an optimal lighting state is formed on the subject H, and then a photographer such as a cameraman operates the camera to take a picture. When the shutter of a camera (not shown) is activated, it is synchronized with this. Then, the strobe light flashes and the subject H is photographed.

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

  The photographing system 2 according to the present invention includes a camera 21 that is a photographing means for photographing a subject H, and a strobe light 25 (25a to 25c) that performs lighting on the subject when photographing with the camera 21 (the same part as the light 11 described above). The control device 23 that controls the operation of various devices used for taking a picture in the photography studio 1, such as the control of the amount of light emitted from the strobe light 25 at the time of photographing, and the photographing environment immediately before photographing. It comprises a detection sensor 24 for detection. In the photographing system of FIG. 2, a main light 25a, a top light 25b, and a background light 25c are arranged, and these lights are used as the illumination light 11 described above and are used for strobe light emission separately from the illumination light. A light is provided. As shown in FIG. 2, the strobe light 25 is supplied with power from a strobe power source 27 and emits light when taking a picture.

  In the photographing system 2 according to the present invention, information relating to the photographing environment detected by the detection sensor 24 immediately before photographing by the cameraman 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 cameraman pressing the shutter of the camera immediately before shooting. 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 strobe light 25, the camera 21, or 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, for example, as shown in FIG. 2, the photographing environment of the photography studio 1 is a physical quantity such as illuminance, luminance, or color temperature detected by the environment measurement unit 28 using the detection information CS detected by the detection sensor 24 that has started operation in response to the shutter signal SS. To the measurement information DS, and this measurement information DS is transmitted to the control device 23. The control device 23 collates the transmitted measurement information DS with the recorded information MS stored in the device 23 and performs a process such as calculation using the recorded information so as to obtain an appropriate strobe lighting condition. The amount of light emitted from the strobe light 25 is controlled by transmitting a power supply amount control signal PS to the strobe power source 27.

  The processing unit 231 of the control device 23 collates and calculates the measurement signal DS, which is a measurement value in the shooting environment, and the record information MS related to the shooting conditions stored in the storage unit 232 such as the main memory in advance. At that time, an optimum strobe light emission amount corresponding to the photographing state at that time is calculated, and the light emission amount of the strobe light 25 is controlled so that the calculated exposure amount is obtained. Here, as information recorded 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 by the camera 21 are supported. Information on strobe emission corresponding to various shooting conditions, such as information on the amount of strobe emission, information on the light receiving element (CCD) performance in electronic cameras and information on strobe emission corresponding to film sensitivity in silver halide photographic cameras ing.

  The control device 23 controls the power supplied to the strobe power supply 27 so that the strobe light 25 emits light with the appropriate exposure amount determined in this way. At this time, a power control signal PS is transmitted from the control device 23 to the strobe power source 27, and the strobe light 25 is controlled so as to perform optimum strobe light emission.

  As described above, the photographing system 2 according to the present invention detects the lighting state in the photographing 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 thereby control the light emission amount of the strobe light 25. Photographing is performed through a process of adjusting to an appropriate level that allows photographing with an exposure amount that is not excessive or insufficient in the photographing environment. Therefore, according to the photographing system 2 according to the present invention, strobe light emission with an appropriate exposure amount according to the photographing situation is performed, so that the strobe light 25 is overexposed or the exposure amount is insufficient to cause a photographing failure. This makes it possible to perform shooting with an appropriate exposure amount at any time.

  The detecting means used in the photographing system according to the present invention detects the photographing environment in the studio immediately before photographing. 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 such as a luminance meter, a spectrocolorimeter, and an illuminometer, and the control device 23 obtains the results obtained by these measuring devices from the control device. The control device 23 collates the measurement result with the information related to the above-described shooting conditions stored in advance in the storage unit in the control device 23, and determines the flash emission amount corresponding to the shooting environment at that time, The power supply amount to the strobe power supply 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 shooting system 2 according to the present invention detects a shooting environment in the studio 1 immediately before shooting and feeds back the detection result to instantaneously set lighting conditions according to the state of the studio where shooting is performed. Detects the shooting environment in the studio immediately before shooting, and combines the detection results with camera shooting conditions such as shutter speed, aperture value, or sensitivity to take a picture so that flash can be emitted according to the situation. .

  When the inventor was evaluating the finish of a printed photograph obtained by taking a photograph under illumination conditions according to the prior art as described in the above-mentioned patent document, the photograph was taken under an illumination condition deviating from the appropriate exposure amount. We noticed that there are surprisingly many printed photographs that seem to have been made. It was unexpected that a lot of such poorly exposed photos would occur even in studio photography.

  The inventor examined the cause of the occurrence of poorly exposed photographs even in studio photography. As a result, it was speculated that the best strobe lighting conditions set based on the lighting conditions in the studio might result in poor exposure depending on the situation. It is not clear why the conditions set in this way result in poor exposure depending on the situation, but from the lighting state that factors such as the subject's clothes, hairstyle, posture, height, or the position of the subject at the time of shooting are considered the best It is presumed that there is a slight deviation and a sufficient exposure amount cannot be obtained with the set strobe emission amount.

  The present inventor confirms the shooting environment immediately before shooting and sets the strobe lighting condition in response to the actual shooting environment, and feeds back the detected state to the control device 23 to emit the strobe light 25. The present invention has been found in consideration of taking a picture after adjusting the amount to be suitable for the lighting environment immediately before taking the picture.

  As described above, according to the present invention, it is possible to grasp the shooting environment immediately before shooting and adjust the flash emission amount, so that it is possible to take a photo in a studio under illumination conditions with no exposure shortage. Thus, it has become possible to stably provide photographic prints with beautiful finishes with appropriate exposure that satisfy the subject. In particular, even when the subjects like Shichigosan and graduation season want to shoot at a time, individual photos are always taken under appropriate exposure conditions, so people with a beautiful finish with a vivid expression A photograph can be obtained stably. In addition, the photographer in charge of photography can greatly improve the work efficiency at the time of photography because there is no need to set detailed lighting conditions according to each customer while customers of various clothes and hairstyles come. It becomes possible.

  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 appropriate strobe light emission is performed for the shooting environment in the photo studio 1. (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 studio is already in a state in which proper strobe light emission can be performed (Yes in step S5), the strobe light 25 is activated and photographing is performed. (Step S6).

  Also, when the control device 23 determines that proper strobe light emission is not performed for the shooting environment in the studio (No in step S5), the control device 23 uses the strobe light 25 based on information from the detection sensor 24. Set the flash conditions so that the appropriate flash can be used. (Step S7). After the setting is made, it is confirmed again whether or not proper strobe light emission can be performed (step S5). When it is determined that proper exposure 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, it is possible to take a human photograph under an appropriate exposure condition by detecting a photographing environment immediately before photographing.
