〔Technical field〕

The present invention relates to a television mannequin and a film camera that can be selected at sea or on land.

(Background technology)

It has been reported that television cameras and film cameras are used for independent purposes, so if you need a still picture while you are on TV, you can use the tape once recorded on video. The method of making a photo was used. However, that method yielded extremely obscure photos.

In order to improve this, conventionally two black and white or color TV cameras and two white or color film cameras were used to provide clear, high-resolution, high-color-reproducibility photographs. Togigi used a method of operating this combined film camera to capture the subject captured by the television camera.

The pictures reproduced from the chip exposed by the video camera had poor resolution and color reproducibility and were extremely unclear, and were indistinguishable from those of the film camera. As shown in Figure 4, the optical paths a and b to the respective lenses of the TV camera A and the film camera B are different from each other. When the distance between the subject and the camera is short as in the case, it is extremely difficult to accurately track the subject C captured by the TV camera, and it is also necessary to eliminate parallax (parallax). Was impossible 16

An object of the present invention is to eliminate the above-mentioned drawbacks in the conventional method, and to directly search for a subject captured by remote monitoring with a television camera. •? Coloring with a film camera on the port enables high-resolution photos with accurate color reproducibility to be obtained.In addition, the operational complexity of the two cameras, a TV camera and a film camera, has been reduced. In particular, it is an object of the present invention to provide a coloring device S that eliminates parallax error of close-up shadows.

(Indication of invention)

An object of the present invention is to provide an optical path changing means connected to a film camera in an optical path of a TV camera connected to a single lens inside a housing, and the TV camera captures the optical camera as needed. This is achieved by constructing the west image of the subject as it is from a film camera.

FIG. 1 is a view showing the overall configuration of the apparatus of the present invention, FIG. 2 is a view taken along the line I--I in FIG. 1, FIG. 3 is a view showing a drive mechanism of the movable mirror, FIG. FIG. 4 is an explanatory view showing a point S of the conventional mounting.

[Best Form for Realizing Kishi Ming] The configuration of the present invention will be described below with reference to the accompanying drawings showing a practical example. 1 and 2, the camera device 1 of the present invention is housed in a completely watertight and water-resistant housing 2 for use in, for example, deep sea: engraving. A dome lens 3 for introducing an incident light beam is provided, and a photographic lens 4 is integrally attached to the dome lens 3. In addition, a television camera 5 is provided in the optical path from the award lens 4, and a film camera 6 is located adjacent to the television camera 5.

The incident light X that has exited the color lens 4 passes through the optical path i, and is imaged and colored on the television camera 5; the mirror 7 (prism) is provided in front of the television camera 5. The first optical path X i, which is a normal incident optical path leading to the television camera 5, is reflected by reflecting the direction of the incident light beam of the subject. 2 incident optical path The input light, which has been subjected to the above-mentioned method, and which has been subjected to focal point separation and aberration correction by the relay lens system 8, is deflected in the optical path direction by the second changing mirror 9 (may be a prism). Then, an image is formed in the film camera 6 provided on this optical path. At the same time, the film is exposed to obtain a predetermined photograph *

The mirror 7 may be a half-mirror system, depending on the degree of perplexity of the television camera 5 and the film camera 6, but in the above-described embodiment, a movable mirror system is adopted. In the case of, a half mirror is used at the position of the mirror 7, and a part of the light of the incident light X passes through the half mirror 7, passes through the first optical path X i, and is imaged on the chirecamera 5. The remaining light of the light X is changed by the half mirror with respect to the first light path X i, and the light path is exhausted as described above to be imaged in the film camera 6.

In the movable mirror method, the movable mirror 7 is usually located at the position a in FIG. 2 and becomes the incident light X—X i, which is photographed by the video camera 5. The mirror 7 moves to the position b by mechanical or electrical action. At this time, the incident light passes through the optical path X-and forms an image on the film camera 6. In addition, according to the still camera's Shakuda's shout, the color of the film camera becomes painful. If the shutter is released, the reverse movement returns to the video color. In Fig. 3, the movable mirror 7 is mounted on a slide glaze 11 and is movable along the core axis 12. In Fig. 3, the movable mirror 7 slides along the core axis 12. 1 is fastened to the solenoid lever 13 with a binge a point. The lever 13 is mounted on the electromagnet device 14 that performs the rotation.Fig. 3) shows the position where the mirror enters the optical path X in Fig. 1, and the state when the film camera is painted. (W is mirror 7 outside optical path X in Fig. 1) The mirror 7 is drawn to the right hand in the illustration business, as shown in the figure (the cn shows the useful drawing of this device. When the shutter of the film camera is pressed, the electromagnet unit S14 is excited and turns in the direction of the arrow A. The mirror lever 7 is rotated, and its power moves the mirror 7 to the position (a) via the slide shaft 11 * This method minimizes the vibration of the reflected light with respect to the incident light. Then, switching from television to film camera is quick. · Unlike the mirror system of the conventional single-lens reflex camera, this is a structure in which the light «I mirror enters when the film camera is painted. It is a particularly nurturing structure

When using a still camera to print a film photo, the exposure must be perfect. · This equipment controls the flash emission time to control the amount of light. Since the exposure is inversely proportional to the square of the separation between the camera and the subject, a method is used in which the reflected light of the strobe from the subject is detected and moved to the strobe, Fig. 1 In the above, a sensor 10 is provided at the center of the variable light mirror 9 and connected to a strobe provided outside the color camera, while a strobe driven by a still camera's shutter is used. The switch of the camera is connected by pressing the shutter of the Stilla camera * This causes the stop port to emit light, and the reflected light from the subject is reflected by the dome lens 3, 摄 ¾ lens 4, movable mirror 7, and relay lens. Pass through 8 to fixed mirror 9 Reaching · As before arrest: The sensor 10 in the center of the fixed mirror 9 collects this light and cuts off the strobe switch when it absorbs a predetermined amount of light. A system that emits signals and supplies the appropriate amount of light to the film

The effects of the device of the present invention are listed below. Φ Since the image of the subject hitting the film is directly colored from the lens that shines on the TV camera, there is no parallax between the image from the TV camera and the true image. In addition, a clear recorded photograph with the same resolution and high resolution can be obtained for all still subjects. (2) Since the subject objective lens can be shared, the entire installation can be made compact, and the structure of the entire photographing device, especially when used for marine observation, etc., is reduced. Can be made smaller and more mobile ·

[Industrial applicability]

The imaging and coloring apparatus S of the present invention can be used as a normal land-based coloring apparatus, but particularly when used in underwater and underwater observation where it is difficult to carry both a television camera and a film camera. The effect is remarkable,
