Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an imaging apparatus suitable for scientific measurement such as high-speed imaging.

[0002]

2. Description of the Related Art By synchronizing and photographing a plurality of such photographing apparatuses, various high-performance photographing can be performed. For example, three-dimensional imaging and simultaneous three-angle imaging are possible by synchronizing (perfectly synchronizing) three imaging devices without providing a delay time. In addition, color photography can be performed by completely synchronizing three monochrome photographing apparatuses each having a color filter attached thereto. Furthermore, high-speed three-time continuous shooting is possible by providing a delay time for the three shooting devices and synchronizing them (delay synchronization).

In the three-dimensional photographing and three-angle simultaneous photographing among the high-performance photographing using a plurality of photographing devices, it is necessary to arrange the photographing devices at positions apart from each other in order to photograph a subject from different angles. There is. On the other hand, in color photography or high-speed continuous photography, it is necessary to arrange a plurality of photographing devices in one place and to input light beams split by light dividing means such as a prism to each photographing device.

Conventionally, in order to perform the above-described high-performance photographing, a plurality of independent photographing devices which are independent from each other are prepared and used with a setting according to a photographing purpose. Further, conventionally, a so-called multi-plate type imaging apparatus provided with a plurality of imaging elements in one imaging apparatus has been provided. For example, Japanese Patent Application Laid-Open No.
The photographing device described in Japanese Patent No.
A light splitting unit for splitting the light and three image pickup devices into which the divided light is incident are provided, and an optical filter can be detachably attached to a front surface of each image pickup device. This imaging apparatus can perform three-spectral imaging such as color imaging or ultra-high-speed three-continuous imaging by combining the type of the optical filter and the timing of imaging.

[0005]

However, if a plurality of independent photographing devices are used, three-dimensional photographing and three-angle photographing can be performed at the same time. It becomes complicated. Specifically, it is necessary to adjust the optical axes of the three photographing devices with respect to the light emitted from the light splitting means such as a prism, and to position them. This operation requires high precision. In general, a photographing device for scientific measurement includes a photographing block, a control block, a recorder, and the like as separate bodies, and these are connected by cables. When three photographing devices are set, these cables intersect. However, the positioning operation requiring high precision as described above becomes more difficult.

On the other hand, a device provided with three image pickup devices, such as that described in Japanese Patent Application Laid-Open No. 5-336420, is suitable for color photographing or ultra-high-speed three-division photographing. Therefore, three-dimensional imaging and three-angle simultaneous imaging cannot be performed. Also, the three imaging devices cannot be used separately in different laboratories or laboratories.

Generally, special cameras for scientific measurement are very expensive. Therefore, it is enormous to purchase three separate cameras for three-dimensional imaging and three-angle simultaneous shooting, and to purchase a three-panel camera for color or three-spectral imaging separately. It is an economic burden.
