Description

  The present invention relates to a subject photographing method for photographing a divided part of a subject, a face photographing method for photographing a divided part of a subject's face, each photographing apparatus adopting each photographing method, and a division photographing adapter used for each photographing apparatus. It is.

  As is well known, when selling cosmetics, the customer's face is photographed at the store and displayed on the display, and the displayed skin is analyzed or the skin condition is analyzed using a skin measuring instrument. Cosmetic counseling that suggests a makeup method suitable for the condition of the face is performed, and the photographing method includes a method of taking the whole face, a method of taking and joining the divided parts of the face, and enlarging only the skin surface of the face Method etc. are adopted.

  In the method of capturing and combining the divided parts of the face, the subject light beam forming the entire subject image is divided into the subject light beam forming the divided subject image by the prism, and each subject image is separated by the same number as the number of divisions. A prism-type division method (see Patent Document 1) for imaging with a CCD imaging device arranged in a position, or holding a photographing device on a photographing stand positioned above a subject, and reflecting a light beam with a mirror to light each portion of the subject There has been proposed a mirror-type division method for imaging by changing the direction of the axis (see Patent Document 2).

Japanese Patent Laid-Open No. 9-214992 JP 2000-250967 A

  Skin analysis requires image data for observation that has a data amount that can be displayed at a high resolution, but the number of pixels that can satisfy this data amount (for example, the state of pores on the average of about 0.2 mm in the industry in detail) In order to capture the entire face, such an expensive digital camera is permanently installed at every store. However, there is a problem that enormous capital investment is required. On the other hand, an inexpensive digital camera with low resolution (for example, 6 million pixels) can obtain image data for observation that can be clearly analyzed. There was a problem that beauty advice based on sufficient skin analysis was not possible.

  In the prism system, the optical axis of the subject luminous flux is separated and reflected by the number of the divided subjects by the prism, and projected onto the photoelectric conversion element to pick up an image. Therefore, the number of divided digital cameras is required. In addition, since it must be configured as a single device, the device becomes too large to be installed in the store, and the resulting image has uneven density when separated on the prism surface. If you do not process and average the density, you can not get a single composite image, but the image data for observation for skin analysis is processed by calculation and it differs from the lightness and darkness of the actual skin, There was a problem that image data for observation that could perform clear skin analysis could not be obtained, and beauty advice based on sufficient skin analysis could not be obtained.

  Furthermore, in the mirror system, since the optical axis is shifted from the center of the subject to each part of the subject, the surroundings of each divided image are distorted, so this can be combined into a single image. Distortion must be corrected, but if the image is processed, the actual skin irregularities cannot be reproduced, so it is not possible to obtain observation image data that can be clearly analyzed, and beauty based on sufficient skin analysis There was a problem that advice could not be given.

  In view of the above-mentioned problems, the present inventors have adopted a division photographing method and have a resolution higher than the resolution of the photoelectric conversion element (for example, CCD) mounted on the digital camera by one digital camera. TECHNICAL PROBLEM TO BE SOLVED: To obtain a photographing method that can photograph a subject and that does not require correction of the entire image when a digital image of each subject obtained by photographing is synthesized, and a photographing device that employs the method. As a result, research and experiments were repeated in order to realize this.

  If the subject is divided and photographed by one digital camera and the divided image data are combined into one piece of image data, the present inventors can obtain the same number as the number of divided subjects in the resolution of the digital camera. It is possible to obtain the same image data as when taken with a digital camera equipped with a photoelectric conversion element having a multiplied resolution. For example, D70 (image element: 23.7 × 15.6) manufactured by Nikon Corporation, which is a 6-megapixel digital single-lens reflex camera. (mm size primary color CCD, total number of pixels 6.24 megapixels, effective number of pixels: 6.1 megapixels) produces an image of 3,008 x 2,000 pixels, that is, about 6,200,000 pixels, but the number of CCD pixels and the pixels of the generated image Even if it does not basically match the number, if two-part shooting is performed, it is assumed that 150 pixels is set for the overlapping portion necessary for stitching when composing images (3,008 × 2-150 ) X 2,000 = 11,732,000, that is, an image of about 11.73 million pixels can be obtained. If four vertical and two horizontal images are taken, (3,008 x 2-150) x (2,000 x 2-150) = 22,584,100, that is, attention was paid to the fact that an image of about 22.58 million pixels can be obtained.

  Therefore, the present inventors adopted a method of taking a picture by moving the digital camera in parallel with the face and a method of taking a picture by changing the orientation of the digital camera. When a face (three-dimensional subject) is shot (see Fig. 1), the digital camera is moved to the left side relative to the face, and the image generated by shooting the face from the left side and the digital camera are moved to the right side. As shown in FIG. 2, the viewpoint generated with respect to the face is different from the image generated by photographing the face from the right, so that the orientation of the face is different between the left image and the right image. Distortion occurred around the captured images, and it was difficult to obtain overlapping portions necessary for stitching the images, so that they could not be easily combined. In order to join them, a considerable overlap width must be set, and the advantage of divided shooting cannot be obtained. Further, when the face was photographed while changing the direction of the camera (see FIG. 3), the divided images were distorted and the images could not be combined (see FIG. 4).

  The present inventors have noticed that the optical axis of the optical system is moved or changed in both of the divided imaging method in the experimental example and the divided imaging method in the conventional example, and the optical axis of the optical system is changed with respect to the face. If you divide and shoot the face with one digital camera in a fixed state, you can shoot the face with a resolution higher than the specifications of the digital camera, and shoot with the optical axis fixed. The result of repeated research and experimentation to realize the idea that the shooting conditions do not change in the divided images, and it is not necessary to correct the entire image when combining each digital image obtained by imaging If the lens part of the digital camera is fixed to the face and the camera body of the image pickup part incorporating the photoelectric conversion element is moved left and right (up and down) to photograph each divided part of the face, FIG. As shown in FIG. 6, when the camera body a is on the left side (upper side) with respect to the face b, as shown in FIG. 6, the right half (lower half) of the entire face focused by the lens unit c is When projected onto the photoelectric conversion element d and the camera body a is on the right side (lower side) with respect to the face b, the left half (upper half) of the entire face focused by the lens unit c is the photoelectric conversion element d. Twice the resolution when the entire face is taken with a single digital camera, and the camera body a, that is, the photoelectric conversion element d with respect to the face b is located at the upper left → upper right → lower right → When the camera is moved to the lower left and divided into four parts, the four parts of the face b collected by the lens part c with the optical axis fixed are in the order of the lower right part → the lower left part → the upper left part → the upper right part. When the entire face is shot with a single digital camera Double the resolution, and the remarkable knowledge that the area of the region drawn as the locus of the photoelectric conversion element d inside the camera body by the movement of the camera body a functions as a single photoelectric conversion element of the division multiple. And the above-mentioned technical problem has been achieved.

  The technical problem can be solved by the present invention as follows.

  That is, in the subject photographing method according to the present invention, an object is imaged by projecting divided parts of the subject from the optical system onto a photoelectric conversion element, and combining the captured digital images of the divided parts into image data of the subject.

  The split adapter 39 is provided with a lens mounting hole 10 for mounting the condensing lens 3, and the optical axis 6 of the condensing lens 3 mounted in the lens mounting hole 10 is fixed and positioned with respect to the face 2. The optical axis fixing unit 7 and an imaging unit mounting unit 36 for mounting the camera body 4 from which the condenser lens 3 is removed are provided, and a photoelectric conversion element built in the camera body 4 mounted on the imaging unit mounting unit 36 5 is positioned on a plane perpendicular to the optical axis 6, and includes the parallel moving unit 8 fixed to the optical axis fixing unit 7 that moves the photoelectric conversion element 5 on the vertical plane. .

  Next, a face photographing method will be described.

  The split adapter 39 is fixed to the pedestal 9 and a condenser lens (for example, a large format camera lens 135 mm / f5.6 manufactured by Fujinon Co., Ltd.) 3 is attached to the optical axis fixing plate 11 of the optical axis fixing unit 7. I removed the single-lens reflex interchangeable lens of a digital camera (for example, Nikon D70 with 6 million pixels: Image sensor, 23.7 x 15.6mm size primary color CCD, total number of pixels 6.24 megapixels, number of effective pixels 6.1 megapixels) A camera body 4 incorporating a photoelectric conversion element (6 million pixel CCD: vertical × horizontal, 2,000 pixels × 3,008 pixels, ie, 15.6 mm × 23.7 mm) 5 is mounted on the camera body holding plate 37 of the translation unit 8. At this time, the position where the condensing lens holding part 35 of the camera body 4 is fitted to the imaging part mounting part 36 of the camera body holding board 37 is a position where the camera body 4 is in the vertical orientation with respect to the split adapter 39. The photoelectric conversion element 5 is positioned on a plane perpendicular to the optical axis 6.

  Next, as shown in FIG. 7, the subject whose skin is to be analyzed is allowed to sit facing the photographing apparatus 1 and positioned so that the optical axis 6 of the condenser lens 3 comes to the approximate center of the face 2 of the subject. At this time, the shutter speed (for example, 1/30) at which the face 2 does not blur with respect to the set sensitivity (for example, ISO 100) and the subject depth (for example, 100 mm) that focuses on the entire face 2 can be maintained. Illumination is determined by a diaphragm (for example, f16 or more), and the subject's face is maintained by maintaining a distance (for example, 90 cm) between the face 2 and the condensing lens 3 where the face 2 is contained in the image circle obtained under each condition. The optical axis 6 is fixed and positioned with respect to 2, the rotary knob 18 is turned to move the fixed platen 11 back and forth to focus, and the screw knob 19 is turned at the focused position to turn the support block 12 to the guide rail 13 Secure to.

  In a state where the optical axis 6 is positioned substantially at the center of the face 2 of the subject, the imaging unit mounting portion 36 of the camera body holding plate 37 is positioned at the center of the support frame portion 22 of the split adapter 39 as shown in FIG. At this time, the condensing lens 3 and the imaging unit mounting unit 36 are in an overlapping positional relationship, and the photoelectric conversion element 5 in the camera body 4 includes an image circle including the projected face 2 as shown in FIG. Located in the center of

  Next, the horizontal movement lever 25 of the support frame portion 22 is operated to move the horizontal movement inner frame portion 28 in the horizontal direction with respect to the split adapter 39, and the vertical movement lever 31 of the horizontal movement inner frame portion 28. To move the vertically moving inner frame 34 in the vertical direction with respect to the split adapter 39, and as shown in FIG. 12, the camera body holding plate 37 is positioned at the upper left of the split adapter 39 (for example, The position where the CCD was moved 7.2mm upward and 11.3mm left from the center position). At this time, the condenser lens 3 and the imaging unit attachment part 36 are in a positional relationship in which the imaging unit attachment part 36 is shifted to the upper left with respect to the fixed condenser lens 3, and the photoelectric conversion element 5 in the camera body 4 is As shown in FIG. 16, when the lower right part which is located in the upper left of the image circle and is divided into four parts on the face 2 is projected and the shutter is pressed, the face on the lower right part is imaged and a digital image of the lower right part is obtained. (For example, 3,008 pixels × 2,000 pixels) is obtained.

  Next, the horizontal movement lever 25 of the support frame portion 22 is operated to move the lateral movement inner frame portion 28 in the right direction with respect to the split adapter 39 in FIG. The panel 37 is positioned on the upper right side of the split adapter 39 (for example, a position moved 11.3 mm toward the right from the position where the CCD is positioned at the center). At this time, the condenser lens 3 and the imaging unit attachment part 36 are in a positional relationship in which the imaging unit attachment part 36 is shifted to the upper right with respect to the fixed condenser lens 3, and the photoelectric conversion element 5 in the camera body 4 is As shown in FIG. 16, the lower left portion obtained by dividing the face 2 into four parts is projected, positioned at the upper right of the image circle such that the left end overlaps the right end of the photoelectric conversion element 5 positioned at the upper left. If the shutter is pressed, the lower left part face is imaged and a digital image of the lower left part is obtained. Therefore, the digital image of the lower right divided portion and the digital image of the lower left divided portion share a digital image (for example, 150 pixels wide) that partially overlaps at the image end.

  Next, the vertical movement lever 31 of the lateral movement inner frame portion 28 is operated to move the vertical movement inner frame portion 34 downward with respect to the split adapter 39 in FIG. The main body holding plate 37 is positioned at the lower right of the split adapter 39 (for example, a position where the CCD is moved 7.2 mm downward from the position where the CCD is positioned at the center). At this time, the condensing lens 3 and the imaging unit mounting unit 36 are in a positional relationship in which the imaging unit mounting unit 36 is shifted to the lower right with respect to the fixed condensing lens 3, and the photoelectric conversion element 5 in the camera body 4 is As shown in FIG. 16, the upper left part obtained by dividing the face 2 into four parts, positioned at the lower right of the image circle with the upper end overlapped with the lower end of the photoelectric conversion element 5 positioned at the upper right. Is projected and the shutter is pressed, the upper left part face is imaged and a digital image of the upper left divided part is obtained. Therefore, the digital image of the lower left divided part and the digital image of the upper left divided part share a partially overlapping digital image (for example, 150 pixels in width) at the image end.

  Next, the horizontal movement lever 25 of the support frame portion 22 is operated to move the lateral movement inner frame portion 28 to the left with respect to the split adapter 39 in FIG. Position the panel 37 at the lower left of the split adapter 39. At this time, the condenser lens 3 and the imaging unit mounting part 36 are in a positional relationship in which the imaging unit mounting part 36 is shifted to the lower left with respect to the condenser lens 3 in a fixed state, and the photoelectric conversion element 5 in the camera body 4 is As shown in FIG. 16, the upper right portion obtained by dividing the face 2 into four parts is projected, positioned at the lower left of the image circle such that the right end is overlapped with the left end of the photoelectric conversion element 5 positioned at the lower right. When the shutter is pressed, the upper right part face is imaged and a digital image of the upper right divided part is obtained. Therefore, the digital image of the upper left divided part and the digital image of the upper right divided part share a partially overlapping digital image (for example, 150 pixels in width) at the edge of the image, and the photoelectric conversion element 5 positioned at the upper left. The upper edge overlaps with the lower edge of the image, and the digital image of the lower right divided portion and the digital image of the upper right divided portion share a digital image (for example, 150 pixels wide) partially overlapping at the image edge. .

  In the present embodiment, when each divided part of the face 2 is imaged, the photoelectric conversion element 5 is moved on the vertical plane of the optical axis 6 and the optical axis 6 is fixed with respect to the face 2 for imaging. Therefore, the imaging conditions do not change in the image of each divided part, and there is no need to process the digital image of each divided part obtained by imaging with the entire image, so the digital image of the lower right divided part can be obtained using an image processing application. The digital image of the lower left segment, the upper left segment and the upper right segment can be easily combined based on the partially overlapping digital images that are shared by each, and the image data of the entire face Can be obtained.

  Further, in the present embodiment, the camera body 4 is moved in the translation unit 8 with the optical axis 6 fixed, so that one segment of the face 2 is projected onto the photoelectric conversion element 5 and adjacent to each other. Since the dividing adapter 39 is used to position the photoelectric conversion element 5 to a position where a digital image partially overlapping the divided part is captured, one photoelectric conversion element 5 is moved in the image circle as shown in FIG. Therefore, image data using the photoelectric conversion elements 5 having a size corresponding to approximately four sheets can be obtained. Therefore, the resolution (for example, 6 million pixels) or more of the photoelectric conversion elements mounted on one digital camera (for example, , (3,008 x 2-150) x (2,000 x 2-150) = approx. 22.58 million pixels), and the facial data for observation has a data amount that can be displayed at a high resolution necessary for skin analysis Can get .

  In the present embodiment, the split adapter 39 that divides the face into four parts has been described. However, the face 2 is divided into two parts or six according to the setting of the stop positions of the horizontally moving inner frame part 28 and the vertically moving inner frame part 34. A divided digital image can be obtained.

At this time, the aperture (for example, f11) and the shutter speed (for example, 1/60) that can maintain the subject depth (for example, 90 mm) that is in focus with respect to the set sensitivity (for example, ISO 100) with respect to the entire five-storied pagoda. Illumination is determined, and the optical axis 6 is fixed with respect to the five-storied tower 40 while maintaining the distance (for example, about 10 m) between the five-storied tower 40 and the condensing lens 3 in which the five-storied tower 40 is accommodated in the image circle obtained under each condition Then, turn the rotary knob 18 to move the stationary platen 11 back and forth to adjust the focus, and turn the screw knob 19 at the focused position to fix the support block 12 to the guide rail 13.

  In a state where the optical axis 6 is positioned at the approximate center of the five-storied tower 40, the imaging unit mounting portion 36 of the camera body holding plate 37 is positioned at the center of the support frame portion 22 of the split adapter 39 (see FIG. 11). As shown in FIG. 20, the photoelectric conversion element 5 in the camera body 4 is positioned at the center of the image circle including the five-story tower 40 to be projected. is doing.

  Next, the vertical movement inner frame portion 34 is moved in the vertical direction with respect to the split adapter 39 by operating the vertical movement lever 31 of the horizontal movement inner frame portion 28, and as shown in FIG. 37 is positioned on the split adapter 39 in the figure (for example, a position where the CCD is moved 22.5 mm upward from the position where the CCD is positioned at the center). At this time, the condensing lens 3 and the imaging unit mounting part 36 are in a positional relationship in which the imaging unit mounting part 36 is shifted upward with respect to the fixed condensing lens 3, and the photoelectric conversion element 5 in the camera body 4 is As shown in FIG. 20, when a lower part positioned on the image circle and divided into five parts of the five-storied tower 40 is projected and a shutter is pressed, the five-storied tower of the lower part is imaged and a digital image of the lower part is obtained. (For example, 3,008 pixels × 2,000 pixels) is obtained.

  Next, the vertical movement inner frame portion 34 is moved in the vertical direction with respect to the split adapter 39 by operating the vertical movement lever 31 of the horizontal movement inner frame portion 28, and the camera body holding plate 37 is moved to the center of the split adapter 39. (Refer to FIG. 11). At this time, the condensing lens 3 and the imaging unit mounting portion 36 are in a positional relationship overlapping with the condensing lens 3 in a fixed state, and the photoelectric conversion element 5 in the camera main body 4 has the above-described relationship as shown in FIG. By projecting a central part located in the center of the image circle and dividing the five-storied pagoda 40 into three parts and pressing the shutter, the five-storied pagoda at the central part is imaged and a digital image of the central part is obtained. Accordingly, the digital image of the lower divided portion and the digital image of the central divided portion share a digital image (for example, 150 pixels wide) that partially overlaps at the image end portion.

  Next, the vertical movement inner frame portion 34 is moved in the vertical direction with respect to the split adapter 39 by operating the vertical movement lever 31 of the lateral movement inner frame portion 28, and as shown in FIG. 37 is positioned under the split adapter 39 in the figure (for example, a position where the CCD is moved 22.5 mm downward from the position where the CCD is positioned at the center). At this time, the condenser lens 3 and the imaging unit mounting part 36 are in a positional relationship in which the imaging unit mounting part 36 is shifted downward with respect to the fixed condenser lens 3, and the photoelectric conversion element 5 in the camera body 4 is As shown in FIG. 20, when the upper part of the five-storied tower 40 positioned under the image circle is projected and the shutter is pushed, the upper five-storied tower is imaged and a digital image of the upper part is obtained. It is done. Therefore, the digital image of the central divided portion and the digital image of the upper divided portion share a digital image (for example, 150 pixels wide) that partially overlaps at the image end portion.

  In the present embodiment, when each divided part of the five-storied tower 40 is imaged, the photoelectric conversion element 5 is moved on the vertical plane of the optical axis 6 and the optical axis 6 is fixed with respect to the five-storied tower 40. Therefore, the imaging conditions do not change in the image of each divided part, and it is not necessary to process the digital image of each divided part obtained by imaging with the entire image. The digital image of the divided portion and the digital image of the lower divided portion can be easily combined based on the partially overlapping digital images that are shared by each, and image data of the entire five-storied pagoda can be obtained.

  Further, in the present embodiment, the camera body 4 is moved in the translation unit 8 with the optical axis 6 fixed, so that one segment of the five-storied tower 40 is projected onto the photoelectric conversion element 5 and adjacent to each other. Since the split adapter 39 is used to position the photoelectric conversion element 5 to a position where a digital image partially overlapping the split part is captured, one photoelectric conversion element 5 is moved in the image circle as shown in FIG. Image data using the photoelectric conversion element 5 having a size approximately equivalent to three is obtained, so that the resolution (for example, 6 million pixels) or more of the photoelectric conversion element mounted on one digital camera (for example, , (3,008 × 3-150 × 2) × 2,000 = about 17.45 million pixels) can be taken.

  In the present embodiment, description has been made using the split adapter 39 that vertically divides the building into three parts. However, depending on the setting of the stop position of the longitudinal movement inner frame part 34, the building is divided into four parts vertically or vertically. A digital image divided into six can be obtained. Also, without using the vertically moving inner frame portion 34 of the dividing adapter 39, the horizontal moving inner frame portion 28 is used to operate the horizontal moving lever 25 of the support frame portion 22 to arbitrarily divide the digital image. It can also be obtained.

  According to the present invention, image data for observation that can be clearly analyzed by a compact photographing apparatus using an inexpensive digital camera (for example, 6 million pixels) can be obtained. It can be widely used for skin analysis for beauty advice that is optimal for the skin of the person.

  In addition, according to the present invention, since a building such as a cultural property can be imaged with high resolution, the amount of data that can display digital information such as a cultural property with high resolution can be stored at a low cost.

  Therefore, it can be said that the industrial applicability of the present invention is very high.
