Portable terminal and control program for portable terminal

A non-transitory computer-readable medium having a control program stored thereon, wherein the control program, when executed by a processor, performs display processing comprising:

• determining a display position of each of a plurality of display objects displayed on a first display region and on a second display region;
• receiving a scroll instruction to scroll the display objects displayed on the first display region and on the second display region, such that one of the first display region and the second display region is a downstream display region in a downstream direction of the scroll instruction and the other one of the first display region and the second display region is an upstream display region in an upstream direction of the scroll instruction;
• and,
• in response to the scroll instruction,
• iteratively reducing a downstream display range being displayed on the downstream display region by a first amount, while maintaining an upstream display range being displayed on the upstream display region, until a sum of the reductions by the first amount equals or exceeds a second amount, and,
• after the sum of the reductions by the first amount equals or exceeds the second amount, moving a furthest display object in the downstream direction in the upstream display range from the upstream display range to the downstream display range, such that the furthest display object is not displayed as being split between the first display region and the second display region.

A display method for a computer to perform display processing comprising:

• determining a display position of each of a plurality of display objects displayed on a first display region and on a second display region;
• receiving a scroll instruction to scroll the display objects displayed on the first display region and on the second display region, such that one of the first display region and the second display region is a downstream display region in a downstream direction of the scroll instruction and the other one of the first display region and the second display region is an upstream display region in an upstream direction of the scroll instruction;
• and,
• in response to the scroll instruction,
• iteratively reducing a downstream display range being displayed on the downstream display region by a first amount, while maintaining an upstream display range being displayed on the upstream display region, until a sum of the reductions by the first amount equals or exceeds a second amount, and,
• after the sum of the reductions by the first amount equals or exceeds the second amount, moving a furthest display object in the downstream direction in the upstream display range from the upstream display range to the downstream display range, such that the furthest display object is not displayed as being split between the first display region and the second display region.
