Information processing apparatus, method and storage medium

An information processing apparatus capable of displaying any area, which has been designated in an image displayed on a screen, upon enlarging the area, comprising:

• a display unit configured to display delimitation line to be used for partitioning the image displayed on the screen into areas, wherein the delimitation line includes a first delimitation line which extends in horizontal direction from right edge of the image to left edge of the image and/or a second delimitation line which extends in vertical direction from top edge of the image to bottom edge of the image;
• an operation unit configured to set the first delimitation line to an arbitrary position in vertical direction or set the second delimitation line to an arbitrary position in horizontal direction in the image displayed on the screen according to user operation;
• a partitioning unit configured to partition the image displayed in the screen into a plurality of rectangular areas based on the position of the first and/or second delimitation lines set by said operation unit;
• a rewriting unit configured to rewrite coordinates of diagonal of each rectangular area partitioned by said partitioning unit so that aspect ratio of each rectangular area corresponds to aspect ratio of the display screen;
• an identifying unit configured to identify each rectangular area of the image partitioned by said partitioning unit and rewritten by said rewriting unit;
• and
• a renewal designating unit configured to renewal-designate designating information for designating the each rectangular area identified by said identifying unit according to user operation,
• wherein the each rectangular area, which has been designated by the designating information, is enlarged and displayed in accordance with enlargement ratio of the size of each rectangular area to the size of the screen.
