[Prior art]

 In underwater photography using an underwater camera, exceptional cases are when the natural light from the sun is sufficiently incident on the water, such as when the position of the sun is low, when there are waves and swells on the water surface, or when the weather is cloudy. , The amount of sunlight is reduced. In such cases, to compensate for the lack of light underwater, underwater photography is performed using lighting with a strobe. The success of underwater photography with strobe lighting depends on the weather, sea surface conditions, sun angle, transparency, transparency and other factors, as described above. Of these factors, transparency is the most important factor affecting photography. Here, the degree of transparency refers to the distance that a diver in the water can see in the horizontal direction, but the light from the sun is scattered by dirt, dirt, and other floating objects in the water after entering the water. Then, the amount of light decreases. Under these conditions, if the flash is fired close to the camera, the turbidity of suspended or suspended objects in the water will receive the flash light and reflect it to create countless light spots. The result is a dirty screen and poor contrast.

Therefore, in flash photography, if the strobe is separated from the camera to emit light, the strongly illuminated suspended or suspended matter immediately before the light-emitting portion will not be reflected in the angle of view, and the beautiful You can take pictures. For this reason, in underwater photography, it is common practice to attach a strobe and move it away from the camera position via the mounting arm.

[0004]

[Problems to be Solved by the Invention] By the way, there are many cameras used for the flash photography described above, and most of them are specialized cameras for underwater photography, and most of the large cameras have the flash attached separately from the camera. . However, digital cameras have emerged as ordinary cameras, such as compact cameras and recent system cameras. Many of these cameras are small, and due to the structure of such small cameras, a strobe light emitting unit is required. Usually, the objective lenses are arranged close to each other. In addition, it is difficult to attach a separate strobe externally to this type of camera, so it is difficult to emit the strobe so that it is suitable for underwater photography. In such a case, it is possible to synchronize the strobe with the slave function.However, if the camera pre-flashes the strobe to prevent red-eye and metering, the slave will be activated at that point and will synchronize with the main flash. Disappears. Therefore, it is difficult to use an external flash with this type of camera properly. A camera with such a structure is equipped with a transparent housing that covers the entire camera.However, when actually performing underwater photography, as described above, the turbidity of suspended matter or suspended matter in the water will cause a flash light. The light is reflected and reflected, and the picture is taken, the screen becomes dirty, and the contrast deteriorates.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a reflector for an underwater camera according to the present invention in an underwater camera in which an objective lens and a strobe light emitting unit are provided close to each other, and the entire housing is covered with a transparent housing. A reflector for emitting the emitted flash light to the upper side of the camera body is attached near the strobe light emitting portion of the camera body, and a reflector for emitting the flash light from the reflector toward the front of the camera body is provided in the housing. The light immediately before the light emitting portion goes upward, and the reflected and scattered light of the suspended or suspended matter strongly illuminated by the light does not directly enter the angle of view.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a housing of an underwater camera according to the present invention, and FIG. 2 is a front view showing a state in which the camera is housed (in the present embodiment, a digital camera is used and a pre-flash flash mechanism strobe is employed). . FIG. 3 is a front view showing a state in which the main body 2 is covered with the housing 1, FIG. 3 is a perspective view showing a state in which a lid on the front of the housing is opened, FIG. 4 is a rear view of the housing, and FIG. is there. In the figure, reference numeral 1 denotes a transparent housing, which is made of a material such as an aluminum alloy, an acrylic resin, an ABS resin, and the like, which is provided with waterproofness, pressure resistance, corrosion resistance, and the like. The housing 1 includes a housing main body 1a covering the camera main body 2, and a lid 1b whose front surface can be freely opened by a hinge 3 on a front lower edge of the housing main body 1a. After loading, the upper edge of the front surface of the housing body 1a and the lower edge of the lid 1b are firmly bound by the clasp 4 to impart waterproofness, corrosion resistance and the like to the camera body 2. A protective pad 6 made of a sponge for protecting the lens from being damaged is attached to a position corresponding to the periphery of the objective lens 5 of the camera body 2 on the back surface of the lid 1b of the housing body 1 and a lens cover. A power dial 7 is provided for turning a power switch ring for controlling opening / closing and power on / off of the power supply 5a. In the figure, reference numeral 18 denotes a finder.

Next, the camera body 2 is provided with an objective lens 5 on the right front side thereof, and a strobe light emitting section 8 is provided in the vicinity of the diagonally upper left side thereof. When the lid 1b is attached to the housing main body 1a, a reflection mirror 9 is mounted so as to be close to the strobe light emitting section 8. The reflecting mirror 9 is projected at an angle of about 45 degrees substantially at the center of a mounting bar 10 provided on the lower edge of the lid 1b, and its tip is brought into contact with the lower edge of the strobe light emitting section 8. It has become. As will be described later, the reflection mirror 9 acts to reflect the flash light from the strobe light emitting section 8 upward to the camera body 2.

At approximately the center of the upper rear side edge of the housing body 1a, a mounting arm 11 of a reflecting plate is extended at an angle of about 45 degrees in front of and above the housing 1, and a reflecting plate 12 further extends at the tip thereof. The illumination light of the reflection mirror 9 is emitted in the forward direction of the camera body 2. The reflection plate 12 is formed of a plate or the like on which an aluminum plate, silver foil paper, or the like is stuck, and in this embodiment, is formed in a substantially inverted trapezoidal shape as shown in FIG.

In this embodiment, the operations of the shutter, the exposure, and the focal length are equivalent to the shutter position on the front surface of the housing lid 1b since the camera body is covered with the housing 1. The shutter is opened and closed by rotating a shutter lever 13 provided at the site. Similarly, a focal length lever 14 and an exposure determination lever 15 are provided on the upper surface of the housing 1 at corresponding positions, and the focal length and the exposure are determined by the rotation thereof. In the drawing, reference numeral 16 denotes a grip of the housing 1, and 17 denotes a grip of the camera body 2.

In the present invention configured as described above, when the shutter lever 13 is rotated and the shutter is pressed toward the subject in water, the flash light from the flash light emitting unit 8 is reflected as shown in FIG. The light is reflected by the mirror 9 and emitted upward from the camera. This light hits a reflector 12 provided on the housing 1 and the subject is irradiated with flash light toward the front of the camera. Therefore, since the flash light from the strobe light emitting section 8 is emitted from above the camera body 2, the flash light does not directly reflect into the turbidity of floating substances and dust in the water, and the turbidity in the water is reduced to reduce the turbidity of the subject. It does not appear on the front or in the surroundings, and has the effect of preventing turbidity and light scattering, as well as a reduction in image contrast and light quantity, which occur in underwater photography using flash light with this kind of small camera.

In the above-described embodiment, a digital camera having a pre-shutter mechanism is used. However, the present invention is not limited to this, and an ordinary small camera or a single-lens reflex camera may have a built-in strobe light emitting unit in a prism storage unit. Furthermore, various strobe lighting can be obtained by appropriately changing the mounting position and mounting angle of the reflecting mirror and the reflecting plate. Next, a mirror was used for the reflector close to the strobe light emitting unit, but the shortage of light quantity cannot be denied but is not limited to this.

[0012]

[Effect of the invention]

 As described above, according to the present invention, the structure is simple, the handleability and the lightness are excellent, and even if the strobe light emitting unit and the objective lens are close to each other, the floating matter and dust in the water can be obtained. There is an advantage that beautiful underwater shooting can be performed without turbidity such as appearing on the screen.
