The present invention is a picture print controlling device. Complex image signals which are input to the device are stored in memory and a picture is displayed on a monitor and/or is printed on a photographic paper. The addresses of a printed picture corresponding to a predetermined area of the monitor screen are separated from the remaining addresses of the screen and stored in designated addresses so that just the picture of the predetermined area can be printed and the remainder of the picture may not printed. If printed, data of the designated addresses are sequentially read to be printed. Furthermore, a user can choose the size and location of the predetermined area of the selected cut partial picture. In addition, the device of this invention may be applied to a picture print device such as a color video printer.
