Output image data generating device & method of generating output image data

Abstract

A CPU 200 selects multiple objective image data GD to be pasted on ornamental image data FD, analyzes the selected multiple objective image data GD, and rates the image qualities of the respective image data GD. The CPU 200 specifies the number of plural layout locations included in the ornamental image data FD and the priority order of the plural layout locations, and allocates the multiple objective image data GD to the plural layout locations in the ornamental image data FD, based on the specified priority order and the ratings of the multiple objective image data GD. The CPU 200 executes image quality adjustment with regard to the multiple objective image data GD allocated to the plural layout locations and pastes the quality-adjusted image data GD on the ornamental image data FD according to layout control information, so as to generate resulting output image data.
