Variable-mafnification image processing apparatus

A variable-magnification image processing apparatus, comprising:

• a magnification setting group storing unit configured to store a magnification setting group including two or more predetermined discrete magnification settings, the magnification setting group being defined such that the magnification settings are selectable in one of decreasing order and increasing order;
• a display magnification obtaining unit configured to obtain a display magnification of an image defined when the image is displayed on a display screen having a predetermined pixel number in such a manner that pixels of the image have a one-to-one relationship with pixels of the display screen;
• a magnification setting selection unit configured to select one of the magnification settings in the magnification setting group in one of decreasing order and increasing order in accordance with a predetermined user operation;
• and
• a display control unit configured to display the image on the display screen at the magnification setting selected by the magnification setting selection unit,
• wherein the magnification setting selection unit is configured to execute at least one of:
• operation to select the obtained display magnification obtained by the display magnification obtaining unit subsequently to a maximum one of the magnification settings which are smaller than the obtained display magnification when a magnifying operation for display magnification is conducted;
• and
• operation to select the obtained displaying magnification subsequently to a minimum one of the magnification settings which are larger than the obtained display magnification when a reducing operation for display magnification is conducted.
