Abstract:
1. An image printing apparatus which includes a reading unit constructed to read an image on an original, and a printing unit constructed to print an image on a print medium on the basis of image data of an image read by said reading unit, wherein the image printing apparatus is configured to copy the image, comprising: an instruction input unit constructed to input one of a plurality of copy modes and an enlargement rate, wherein the copy modes include a first copy mode which is image quality-oriented and a second copy mode which is speed-oriented; a plurality of enlargement/reduction units constructed to have different performances to enlarge/reduce the image data, wherein the enlargement/reduction units include a first enlargement/reduction unit with high image quality performance and a second enlargement/reduction unit with high processing speed performance; a decision unit constructed to decide a utilization ratio of each of said plurality of enlargement/reduction units in accordance with the copy mode and the enlargement rate input by said instruction input unit; and a copy control unit constructed to control copying of the image by causing a first one of said plurality of enlargement/reduction units to execute enlargement/reduction processing to target image data, by causing a second and different one of said plurality of enlargement/reduction units to execute enlargement/reduction processing to the target image data to which the enlargement/reduction processing has been executed by said first one of said plurality of enlargement/reduction units in accordance with the utilization ratio decided by said decision unit, and by causing said printing unit to print the image on the basis of the target image data that has undergone the enlargement/reduction processing by said first and second ones of said plurality of enlargement/reduction units, wherein said decision unit decides the utilization ratio so as to preferentially use the first enlargement/reduction unit before the second enlargement/reduction unit in a case where said instruction input unit inputs the first copy mode, and decides the utilization ratio so as to preferentially use the second enlargement/reduction unit before the first enlargement/reduction unit in a case where said instruction input unit inputs the second copy mode.
