Abstract

PURPOSE: To adjust the print contrast properly in a short time even if a printer represents a low gradation by using a microcomputer incorporated in an electronic camera, analyzing the density in a picture and assigning to a printer optimizingly the gradation.
CONSTITUTION: A picture data displayed on a screen of a measuring instrument or the like is given to a frame memory 19 through a hood 11 or the like. The lightness and the distribution characteristic diagram of picture element number having the lightness are generated by a microcomputer 28 at printing from the data and a point (a) being a certain level SHD or below and the darkest point where the lightness is decreased monotonously is detected. Then a point (b) closest to the point (a) brighter than that at the point (a) and whose level is SHD or over is detected by increasing gradation by one and then monotonously. Then one gradation is assigned from the point (a) to the point (b) and (n-2)- gradation is assigned uniformly to remaining effective data parts. Thus, the gradation is assigned to each picture element optimizingly and each picture is printed out by a printer according to the gradation in a short time automatically.
