The image processing apparatus subjects input image data to predetermined image
processing to create output image data to be output as a print. The processing
apparatus includes an extracting device for extracting a main subject from the
input image data and a first determining device for determining a print magnification
and a frame position in accordance with a size of the extracted main subject and
a previously designated print size. The processing apparatus optionally includes
a second determining device for determining a use of the print from an identification
code input when a photograph is taken. The certification photograph taking apparatus
includes an inputting device for inputting an identification code indicating a
use of a print and optionally a print size. The certification photograph creation
system includes the certification photograph taking apparatus, an image inputting
apparatus for inputting a photographed image, the image processing apparatus and
a printer for outputting an image having been subjected to the image processing
as a certification photograph. The processing apparatus, the taking apparatus and
the system are capable of simply and easily taking and/or creating the certification photograph.
