PURPOSE: To equally divide an object so as to transmit an image onto a multivision unit screen by means of one CCD camera at every divided object by arranging the plural broups of mobile mechanism of the CCD cameras, where the image is formed by means of moving in a three-dimentional direction for the object.

CONSTITUTION: The mobile mechanisms 1 which are constituted in such a way that a second travelling object 3 moving on a segment in the vertical direction is mounted on the first moving object 2 moving on the segment, the third moving object 4 moving in the direction of object hight is mounted on the second moving object 3 and a signal form CCD camera 25 is fixed on the third moving object 4 by permitting it to face to the object in a lower direction are plurally provided. A picture-writing device is constituted of the four groups of mobile mechanisms 1 for inputting the image which is divided into four by the four CCD cameras 25. The respective CCD cameras 25 are respectively and independently movement-adjusted in the hight direction, the circumferential direction and the radius direction around a mechanism base 40 and the center of the object so as to be fixed. Thus, the high definition image with four-fold scanning lines can be displayed on a multivision.
