In addition, as shown in FIG. 28, the transfer unit 600 is disposed between the two frame structures 500 and 700, and the process unit 1 mounted on the front frame structure 500 and the rear frame structure The camera module array 121 may be transferred between the process units 1 mounted on the 700.

In this way, in a system in which a plurality of process units 1 are stacked, each process unit 1 may include a control unit according to the present invention. In this case, each control unit may be linked through a mutual communication network or may be connected to a main control unit that controls the system.

Although the preferred embodiments of the present invention have been exemplified and described above, those skilled in the art variously modify and change the present invention without departing from the technical details and scope of the present invention as set forth in the claims below. You can understand that you can do it. Therefore, changes in the embodiments of the present invention will not be able to escape the technology of the present invention.
