The light unit 3 is, as shown in FIG. 3, a cylindrical first cover 3A in which the tip of a conical body is cut, a light emitting portion 7 attached to the tip of the first cover 3A, and light emission A second cover body 3B is provided to cover the portion 7. The first cover 3A and the second cover 3B are made of, for example, a resin such as a polyvinyl chloride derivative or an acrylic resin.

  The light emitting unit 7 is provided with an LED (Light Emitting Diode) 11 a mounted on the LED substrate 11 and an LED 12 a mounted on the LED substrate 12 as a light source. Here, the LED 11 a is covered by the polarizing filter 13, while the LED 12 a is not covered by the polarizing filter 13. The cover member 6 is fitted in the opening of the tip of the second cover 3B, and contacts a skin diseased part which is a subject at the time of dermoscopy photography.

  A window 15a is provided at a position corresponding to the power lamp 17 of the camera body 1 on the upper right side of the first cover 3A in the drawing, and the lighting state of the power lamp 17 on the light unit 2 side of the window 15a A photo sensor 15 is mounted as light receiving means for receiving light. The photo sensor 15 is connected to the LED control board 16 by, for example, a wire (not shown), and the LED control board 16 is also connected to the LED substrate 11 on which the LED 11 a is mounted by a wire (not shown) There is. Thus, in the first embodiment, it is possible to interlock the camera body 1 and the light unit 3 with the release.

  FIG. 4 shows a front view of the light unit 3. The LED 11a mounted on the LED substrate 11 and the LED 12a mounted on the LED substrate 12 do not cause unevenness in the light to be irradiated. An example in which a pair is provided so as to be in a zigzag form is shown. As described later, only the pair of LEDs 11a is turned on when irradiating polarized light, and only the pair of LEDs 12a is turned on when irradiating non-polarized light.

  3 and 4 show the embodiment in which the LED 11a is covered by the polarizing filter 13 and the LED 12a is not covered by the polarizing filter 13, but the LED 11a and the LED 12a are prepared for use when the polarization effect is always required. Alternatively, both of the LED 11 a and the LED 12 a may be covered by the polarizing filter 13 so that both the LED 11 a and the LED 12 a are not covered by the polarizing filter 13 in preparation for use when the polarizing effect is not always required. It is also good. That is, whether or not the polarizing filter 13 is necessary may be determined according to the condition of the skin diseased part, but as shown in FIG. 3, both the LED 11 a covered by the polarizing filter 13 and the LED 12 a not covered by the polarizing filter 13 2 and automatically switches between the LED 11a and the LED 12a at the time of continuous shooting by the continuous shooting operation switch 18 (ON / OFF) shown in FIG. It becomes possible to realize by operation. When the polarizing filter 13 is attached, it is possible to remove unnecessary reflection on the skin surface in combination with the polarizing filter 14 that covers the tip of the imaging lens system 1 d of the camera body 1 and to examine a clear epidermal condition.

(Operation of dermoscopy camera 10)
The operation flow of the dermoscopy camera 10 will be described with reference to FIG. FIG. 5 shows a case where the LED 11a covered by the polarizing filter 13 in the light unit 3 starts from the lighted state (step S301 in the light unit 3 illustrated on the left side in the drawing).

  First, the power of the dermoscopy camera 10 is turned on in the controller 2 (step S101). Then, the power lamp 17 of the camera body 1 turns from green to green as a detectable means. Next, continuous shooting setting is performed by the controller 2 (step S102), and release is operated by the shutter button 2a (step S103).

  At this time, in a state where the power button 8 of the light unit 3 is turned on, switching between the continuous shooting mode and the switching continuous shooting mode is switched by the continuous shooting operation switch 18 (ON / OFF). Here, with normal continuous shooting, the continuous shooting operation changeover switch 18 is turned off, so that either the LED 11 a covered with the polarizing filter 13 or the LED 12 a not covered with the polarizing filter 13 emits light continuously under the same LED. On the other hand, switching continuous shooting automatically turns on the continuous shooting operation changeover switch 18 to automatically switch the LED 11a covered by the polarizing filter 13 and the LED 12a not covered by the polarizing filter 13 This means continuous shooting under different LED illumination in switching.

  If the continuous shooting operation switch 18 is off at the time of release, that is, if the normal continuous shooting is YES ("Y" in step S104), the power lamp 17 is kept in the green state and the illumination of the LED 11a is The image processing is performed in the two-frame continuous shooting in (step S301) and stored (step S105).

  On the other hand, if the continuous shooting operation switch 18 is ON during relays, that is, if the normal continuous shooting is NO ("N" in step S104), after the first image is shot under the illumination of the LED 11a. (Step S106), the power lamp 17 changes the green lighting state to the red lighting state or the extinguishing state (step S107), and the photosensor 18 (light receiving element) senses the changed state of the power lamp 17 (right side in FIG. Step S302) in the light unit 3 shown in FIG.

  When the photosensor 18 (light receiving element) senses the changed state of the power lamp 17, the light unit 3 immediately turns off the LED 11a and turns on the LED 12a (step S303) to match the timing of the second continuous shooting. Then, the second shooting is performed as continuous shooting under the illumination of the LED 12a (step S108). Thereafter, the power lamp 17 is returned from the red lighting state or the light off state to the green lighting state (step S109), and the photosensor 18 (light receiving element) senses the changed state of the power lamp 17 (step S304).

  The first image photographed under the illumination of the LED 11a and the second image photographed under the illumination of the LED 12a are subjected to image processing as two-frame continuous copying and stored (step S110). When the light unit 3 senses that the photo sensor 18 (light receiving element) returns the power lamp 17, the light unit 3 turns off the LED 12a and turns on the LED 11a, and returns to the state of step S301 (step S305).

  Thus, in the dermoscopy camera 10 according to the first embodiment, photographing under the irradiation of the LED 11 a covered with the polarizing filter 13 and photographing under the irradiation of the LED 12 a not covered with the polarizing filter 13, ie, the polarization effect It becomes possible to shoot continuously with or without one shutter operation.

  In FIG. 5, starting from the state in which the LED 11a covered by the polarizing filter 13 is turned on, the lighting state of the power lamp 17 is changed to switch to the LED 12a not covered by the polarizing filter 13 and continuous shooting is performed. However, it is covered by the polarization filter 13 by changing the lighting state of the power lamp 17 starting from the state in which the LED 12a not covered by the polarization filter 13 is on. It is also possible to switch to the LED 11a and shoot continuously. Furthermore, both continuous shooting may be set selectively.

Second Embodiment
Next, the dermoscopy camera 20 according to the second embodiment will be described. In the second embodiment, the type of LED is enhanced as a light source, and in addition to the visible light LED 211 a and the LED 212 a, a near infrared light LED 215 a is provided. The near-infrared light LED 215a may be replaced by an ultraviolet light LED, or in addition to the near-infrared light LED 215a, an ultraviolet light LED may be provided. In the following, an example in which the visible light LED 211 a and the LED 212 a and the near infrared light LED 215 a are provided is described, and switching is performed at high speed by one shutter operation at the time of continuous shooting described in the first embodiment. It is possible to shoot three types of light sources. Hereinafter, differences from the first embodiment will be mainly described.

  FIG. 6 is a front view of the imaging device according to the second embodiment. FIG. 7 is an exploded perspective view of FIG. FIG. 8 is a perspective sectional view of the light unit 23 in FIG. FIG. 9 is a perspective sectional view of the camera body 21 in FIG. FIG. 10 is a front view of the light unit 23 in FIG. FIG. 11 is a cross-sectional view of the light unit 23 in FIG. 10 taken along the line XX. FIG. 12 is a cross-sectional view of the light unit 23 taken along the line Y-Y.

  As shown in FIG. 6, the dermoscopy camera 20 (imaging device) is integrated by a camera body 21, a light unit 23 provided in front of the camera body 21, and a controller 22 provided behind the camera body 21. Is configured. When this is disassembled according to FIG. 7, the camera body 21 includes the lens unit 21A and the frame 21B, the light unit 23 includes the first cover 23A and the second cover 23B, and the controller 22 includes the body 22A and It includes a circuit board 22B and a display unit 22C.

  More specifically, the light unit 23 is configured to be enlarged in FIG. 8 to show a perspective cross section. A first point different from the first embodiment is that an LED 216 for normal imaging is provided as a light source used when imaging the skin diseased part in a state of being separated without contacting the skin diseased part. The LEDs 216 for normal shooting are arranged in a ring shape facing forward around the base end (rear side) of the second cover body 23B, and in FIG. 6 and FIG. An example in which the pieces are arranged is shown. Although FIG. 8 does not draw the entire eyebrows in the drawing, it shows an example in which a total of eight are arranged.

  The LEDs 216 for normal imaging are arranged concentrically at equal intervals with respect to the center of the second cover 23B, and function as a ring flash that emits light forward from the outer peripheral position of the imaging lens system 21d. The normal shooting LED 216 is configured of an LED that emits white light. A cover member 26 is fitted in the opening at the tip of the second cover body 23B, and contacts a skin diseased part which is a subject at the time of dermoscopy photography.

  A second point different from the first embodiment is that the light emitting unit 27 is provided with a near-infrared light LED 215a as a light source for dermoscopy photography in addition to the visible light LED 211a and the LED 212a as described above. That these LEDs form a pair at the top and bottom, and a pair of visible light LEDs 211a covered by the polarizing filter 213 and a pair of visible light LEDs 212a not covered by the polarizing filter 213 are arranged in a staggered manner , It is the same as that of the first embodiment.

  The camera body 21 is attached to the first cover body 23A via a frame 21B that supports the lens unit 21A so as to surround it. When the lens unit 21A is extracted and its cross section is shown, it is as shown in FIG. The circuit wiring board 21b and the imaging element 21c are accommodated on the rear side of the imaging lens system 21d, that is, on the rear surface of the housing 21a, and an infrared cut filter 21e (IRCF) and a near infrared transmission are arranged in order from the front. A filter 21 f and a polarization filter 21 g are disposed. The near-infrared transmission filter 21 f is replaced by an ultraviolet transmission filter when the near-infrared light LED 215 a of the light unit 23 is replaced by an ultraviolet light LED. A flexible circuit board 21 h for operating the lens unit 21 A by the controller 22 extends on the left side in the drawing.

  Here, in the case of diagnosis of a skin diseased part, in addition to dermoscopy photography with visible light, it is preferable to configure so as to be able to emit near infrared light and ultraviolet light as follows. Near-infrared dermoscopy is suitable for photographing the deepest part (dermis) of the skin, and as the wavelength is shorter than that, the light tends not to reach the deep part. Also, melanin in pigmented lesions and hemoglobin in hemangiomas can be a pigment that brings about a change in the color tone of the skin diseased area, while visible light is suitable for the latter oxyhemoglobin, while the former dopa melanin has longer wavelengths. The ultraviolet light whose wavelength is shorter than visible light is more effective because the absorption efficiency of

  FIG. 10 is an enlarged front view of the light unit 23, but the respective light sources LED 215a, LED 211a, LED 212a, and LED 216 have four patterns by means of control as described in the first embodiment. It becomes possible to light up. That is, a first pattern for lighting the pair of upper and lower LEDs 215a of near infrared light (or ultraviolet light), a second pattern for lighting the pair of upper and lower LEDs 211a of visible light covered with the polarization filter 213, and the change filter 213 A third pattern is to light up a pair of upper and lower LEDs 212 a for visible light that are not lighted, and a fourth pattern to light up the LEDs 216 for normal imaging (here, a total of six).

  As continuous shooting by one shutter operation, automatic continuous shooting can be configured such that the first pattern to the third pattern used for dermoscopy photo shooting are performed in random order. Furthermore, automatic continuous shooting can also be configured including the fourth pattern for normal shooting.

  11 shows a cross section (vertical cross section) taken along line X-X in FIG. 10, and a cross section taken along line Y-Y (horizontal cross section) shown in FIG. 10 in FIG. FIG. 11 shows the vertical angle of view θx when dermoscopy is performed in the first to third patterns. In the case of vertical, since the LED 215a, the LED 211a or the LED 212a is irradiated with light in a tapered shape toward the optical axis of the imaging lens system 21d, the imaging lens system 21d of light reflected from the skin diseased part in contact with the cover member 26 The vertical angle of view θx incident on the light becomes relatively narrow. For example, in FIG. 11, the vertical angle of view θx is 35.2 °.

  Note that, in FIG. 11, a wire 28 and a terminal 28a for supplying a control signal to the LED 215a (including the LED 211a and the LED 212a) are provided in a pair at the top and the bottom. Further, in the vicinity of the outer periphery of the first cover body 23A, a wire 29 and a terminal 29a for sending a control signal to the LED 216 shown in FIG. 12 are provided.

  FIG. 12 shows the horizontal angle of view θy when dermoscopy is performed in the first to third patterns. When horizontal, the LED 215a, the LED 211a, or the LED 212a is irradiated in parallel with the optical axis of the imaging lens system 21d, and thus the horizontal image of light reflected from the skin diseased part in contact with the cover member 26 enters the imaging lens system 21d. The angle θy becomes relatively wide. For example, in FIG. 12, the horizontal angle of view θy is 47 °.
