Content generation method for electronic books and computer-readable medium

Abstract

A method is provided for placing a first content and a second content on a display screen at a distance D along a Y-axis in an orthogonal coordinate system formed by an X-axis and the Y-axis. The method includes identifying, in the first content, a first non-display-target region which is located on the second content side, identifying, in the second content, a second non-display-target region which is located on the first content side, calculating a plurality of total widths each of which is a sum of a width of the first non-display-target region in a direction of the Y-axis and a width of the second non-display-target region in the direction of the Y-axis, the widths being at a same X-coordinate, and determining the distance D based on the plurality of total widths and a predetermined reference.

 identifying a first non-display-target region which is part of a non-display-target region obtained by excluding a region of the first display target from a region of the first content and which is located on the second content side;   identifying a second non-display-target region which is part of a non-display-target region obtained by excluding a region of the second display target from a region of the second content and which is located on the first content side;   calculating a plurality of total widths each of which is a sum of a width of the first non-display-target region in a direction of the Y-axis and a width of the second non-display-target region in the direction of the Y-axis, the widths being at a same X-coordinate;   determining the distance D based on the plurality of total widths and a reference value; and   generating electronic book data including the first content and the second content that have said distance D,   wherein   the reference value is a reference serving as a target value of a distance between the region of the first display target and the region of the second display target and is one of values of a predetermined distribution function which is predetermined independent of the two display targets and is not a constant function, and   in the determining of the distance D, the steeper is a slope of a function obtained by plotting the plurality of total widths arranged in ascending order at equal intervals in a direction of a horizontal axis with a vertical axis representing values of the total widths, the smaller is the reference value.
