Description

Dual Head Cameras {CAMERA WITH DUAL HEAD}

The present invention relates to a camera, and more particularly, to a CCD camera for photographing a subject using a charge coupled device (CCD), which is an imaging device.

In general, a CCD camera is a camera that converts an image formed by a lens into an electrical signal from a CCD so that an image of a subject formed on the screen of another external device appears.

Such CCD cameras are used for medical applications, especially dentistry, skin observation, and the like, and are also widely used for industrial purposes, in particular, for various vision and analysis purposes.

When the CCD camera is used for medical, industrial, or other purposes as described above, the user may newly set a condition each time the subject is photographed or the two condition values may be set differently to observe two subjects. Camera was used.

Therefore, in using a CCD camera, there is a disadvantage in that the preparation of the process of observing a subject is too long in the conventional case by resetting conditions every time when observing a different subject as in the former case, and using two CCD cameras as in the latter case By doing this, there were costly disadvantages.

Therefore, an object of the present invention is to solve the conventional disadvantage by providing a dual head camera made of two imaging parts, namely, two heads, of an CCD camera moving to the subject side to image an object.
