  FIG. 7 is a diagram illustrating a necessary angle of the inclination angle of the top surface of the wearable camera 100 according to the first embodiment. Hereinafter, the wearable wearable camera 100 and the suspicious person 20 will be described while explaining the relationship between the position of the top surface of the wearable camera 100 worn by the police officer 10 and the position of the eye of the suspicious person 20 when the police officer 10 and the suspicious person 20 face each other. The required angle of the tilt angle of the top surface of the camera 100 is shown.

<In the case of standard conditions>
Reference numeral 301 indicates the position of the wearable camera 100 attached to the chest when the height of the police officer 10 is assumed to be 180 cm. A two-dot chain line denoted by reference numeral 302 indicates an extension line in the front direction of the inclination angle of the top surface of the wearable camera 100 in that case (80 degrees with respect to the vertical line, that is, 10 degrees with respect to the horizontal line). .

  On the other hand, the code | symbol 303 has shown the position of the eyes | visual_axis when the height of the suspicious person 20 is assumed to be 180 cm. A solid line 304 indicates an extension line in the front direction of the line of sight to the top surface of the wearable camera 100 indicated by 301 in that case. When the police officer 10 and the suspicious person 20 approach to a distance of 2 m, the angle of the line of sight is 81.99 degrees with respect to the vertical line, that is, 8.01 degrees with respect to the horizontal line.

  In the above case, the inclination angle (10 degrees) of the top surface of the wearable camera 100 is sufficiently larger than the angle (8.01 degrees) of the line of sight from the suspicious person 20, so the LED 104 arranged on the top surface The light is blocked by the area on the front side of the top surface of the wearable camera 100 and cannot be visually recognized by the suspicious person 20.

  Considering the average height of the police officer 10 and the average height of the suspicious person 20 who is a general person (the height of the police officer who is restricted in hiring is often high), the sight line of the suspicious person 20 further decreases, As discussed above, it is sufficient that the inclination angle of the top surface of the wearable camera 100 is 10 degrees or more.

  In the above description, the inclination angle is calculated on the assumption that the height of the police officer 10 and the suspicious person 20 is 180 cm, but the average height varies depending on the country or region. However, even in that case, it is considered that the relationship between the average height of police officers and ordinary people is maintained, so the above consideration is valid regardless of the country or region.

<When conditions are strict>
Reference numeral 305 indicates the position of the wearable camera 100 when the wearing position is lowered by 5 cm (or when the height of the police officer 10 is assumed to be 175 cm). A two-dot chain line denoted by reference numeral 306 indicates an extension line in the front direction of the inclination angle of the top surface of the wearable camera 100 in that case (80 degrees with respect to the vertical line, that is, 10 degrees with respect to the horizontal line). .

  On the other hand, the reference numeral 307 indicates the position of the line of sight when the position of the line of sight of the suspicious person 20 is raised by 2.5 cm (or the height of the suspicious person 20 is assumed to be 182.5 cm). A solid line 308 indicates an extension line in the front direction of the line of sight to the top surface of the wearable camera 100 indicated by reference numeral 305 in that case. When the police officer 10 and the suspicious person 20 approach a distance of 2 m, the angle of the line of sight is 77.8 degrees with respect to the vertical line, that is, 12.2 degrees with respect to the horizontal line.

  In the above case, the tilt angle (10 degrees) of the top surface of the wearable camera 100 is smaller than the angle of the line of sight from the suspicious person 20 (12.2 degrees), so the light of the LED 104 arranged on the top surface Can be seen from the suspicious person 20. Therefore, in order to prevent the light of the LED 104 arranged on the top surface from being visible to the suspicious person 20, the tilt angle of the top surface of the wearable camera 100 is at least 12.2 degrees, preferably up to 13 degrees or more. It needs to be bigger.

  As discussed above, the inclination angle of the top surface of wearable camera 100 may be 10 degrees or more, preferably 13 degrees or more.

  It should be noted that it is reasonable that the angle of inclination of the top surface of the wearable camera 100 is allowed up to 45 degrees for the police officer 10 to look down with a line of sight. However, depending on the material of the uniform of the police officer 10, if the top surface is tilted, there is a problem that the light of the LED 104 is reflected on the uniform, so the tilt angle of the top surface is preferably as small as possible (of course, better) , Preferably 13 degrees or more).

  As described above, the wearable camera 100 according to the present embodiment is configured such that the top surface of the housing is inclined so that the back side is lower than the front side. In other words, the angle formed between the top surface and the front surface of the housing is configured to be smaller than the angle formed between the top surface and the back surface. In other words, the housing is arranged so that the light emitted from the LED 104 on the top surface of the housing cannot be seen from the subject, that is, the light is blocked by the area on the front side of the top surface when viewed from the subject. The top of the body is constructed.

  Thereby, it is possible to prevent the light emission of the LED that displays the recording state from being seen from the front.

  Further, the LED 104 on the top surface of the housing is disposed in a region on the back side with respect to the central portion of the top surface.

  Thereby, since the height at which the display unit is positioned can be lowered with respect to the front side of the top surface, even if the display unit is a light emitter, it can be hidden from the subject side.

  The inclination angle formed by the top surface of the housing is 10 degrees or more, preferably 13 degrees or more with respect to the horizontal plane.

  Thereby, even when the subject is close, the display unit can be hidden from the subject side.

  The wearable camera 100 is preferably used while being worn on the chest, but when the police officer 10 faces sideways, the wearable camera 100 faces the suspicious person 20 so that the wearable camera 100 faces the suspicious person 20, for example, at the shoulder. It may be attached.

(Second Embodiment)
In the second embodiment, a configuration different from the configuration of the top surface of the wearable camera 100 shown in the first embodiment will be described.

  In particular, the case where the inclination angle of the top surface of the wearable camera 100 shown as preferable in the first embodiment cannot be secured will also be mentioned. The case where the tilt angle cannot be secured is a case where there is a problem of light reflection on a uniform or the like in addition to restrictions on mounting.

  8 to 9 are diagrams showing the inclination angle and the step of the top surface of the wearable camera 100 according to the second embodiment. FIG. 8 is a top view of the wearable camera 100 according to the second embodiment. In addition, the part which overlaps with the wearable camera 100 in 1st Embodiment is demonstrated using the same code | symbol.

  In FIG. 8, the top surface of the wearable camera 100 has a step bottom surface 402 and a step top surface 403 formed by a step portion 401 provided on the top surface. A portion indicated by shading in the area on the back side of the top surface when viewed from the front surface where the imaging lens 101 is disposed hits the step bottom surface 402.

  The LED 104 is disposed on the step lower surface 402. In that case, the LED 104 is disposed in a region near the step portion 401 on the step bottom surface 402.

  Here, in the wearable camera 100 according to the present embodiment, as is clear from the above description, the most characteristic feature is that the top surface of the housing is configured with a step so that the back side is lower than the front side, and the LED 104 Is arranged on the top surface on the back side of the stepped portion 401.

  FIG. 9 is an enlarged view of the configuration of the top surface portion of the AA cross section of wearable camera 100 shown in FIG.

  In FIG. 9, the top surface of the wearable camera 100 is configured with a stepped portion 401 having a height of 1.5 mm so that the stepped lower surface 402 on the back side is lower than the stepped upper surface 403 on the front side. In addition, the inclination | tilt angle of the top | upper surface is 10 degree | times similarly to the case of 1st Embodiment.

  A dotted line 404 indicates a virtual inclination angle of the top surface connecting the vertex of the angle formed by the stepped portion 401 and the stepped upper surface 403 and the vertex of the angle formed by the lower stepped surface 402 and the back surface. The angle of inclination is 68.38 degrees with respect to the vertical line, ie 21.62 degrees with respect to the horizontal line.

  That is, according to the configuration of the present embodiment, even if the actual inclination angle of the top surface is 10 degrees, the virtual inclination angle can be secured at 21.62 degrees. For this reason, the angle at which the top surface is inclined can be minimized. For example, depending on the material of the uniform of the police officer 10, when the top surface is inclined, the light of the LED 104 is reflected on the uniform. This is very effective when

  As described above, the top surface of the housing of the wearable camera 100 is configured with a step so that the back side is lower than the front side, and the display unit is disposed on the top surface on the back side of the step. Therefore, the display unit can be hidden from the subject side even when the tilt angle is not less than 10 or preferable 13 degrees or more.

  In addition, since the display unit is disposed in a region near the stepped portion 401 of the stepped lower surface 402 of the top surface on the back side, the display unit can be hidden from the subject side even when the subject is close.

  The inclination angle of the step lower surface 402 is not necessarily the same as that of the step upper surface 403. For example, the step lower surface 402 may be horizontal.

  INDUSTRIAL APPLICABILITY The present invention is useful for a wearable camera that is worn and used by a person who performs security such as a police officer.
