Output image data generation device and an output image data generating method

CPU200 acquires one or a plurality of image data GD to be pasted from a plurality of captured image data GD input to the decoration image data, and acquires the image processing control information GI associated with the acquired image data. CPU200 acquires the desired decoration image data FD, and acquires the layout control information LI from the obtained ornamental image data FD. CPU200 further acquires the image quality adjustment information GC from the obtained layout control information LI. CPU200 executes the image quality adjustment on the captured image data GD by using the acquired image processing control information GI and the image quality adjustment information GC. CPU200 may each captured image data GD obtained by the image quality adjustment, stuck on decoration image data FD according to the layout control information LI, generates image data for output.
