Display apparatus scrolling first image and second image in accordance with speed of scroll operation

A display apparatus comprising:

• a display device;
• a touch panel;
• and
• a control device including a processor and functioning as a controller as a result of executing a display change program by the processor,
• wherein the controller causes the display device to display, in a display region previously defined, one portion of a first image including a first plurality of items arrayed along a vertical direction,
• each of the first plurality of items includes a first character string composed of a plurality of characters arrayed along a horizontal direction,
• the controller
• calculates, upon receiving scroll operation in the vertical direction via the touch panel, a speed of the scroll operation
• causes the display device to scroll, in the display region, the first image in the vertical direction, when the calculated speed is equal to or less than a first speed previously defined, and
• causes the display device to generate, when the calculated speed exceeds the first speed previously defined, a second image including a second plurality of items, in which the first plurality of items is rearranged to be arrayed along the horizontal direction, so as that each of the second plurality of items includes a second character string in which the plurality of characters composing the first character string is rearranged to be arrayed along the vertical direction and so as that a number of the characters in the horizontal direction in the second character string is less than a number of the characters in the horizontal direction in the first character string, and causes the display device to scroll, in the display region, the second image generated, in the vertical direction, and
• the controller sets a length of the display region in the horizontal direction to be greater than a length of the display region in the vertical direction.
