Abstract

A display control apparatus includes a display control means. In the display control apparatus, the display control means is configured to scroll-display a plurality of contents. If it is determined that the speed of the scroll display has increased to reach a first predetermined value, then the display control means classifies and groups the plurality of contents by using group classification information corresponding to the plurality of contents and displays the grouped contents. On the other hand, if it is determined that the scroll speed has decreased to reach a second predetermined value, then the display control means sorts the plurality of contents in order according to a selected grouping method and displays group classification information images at a group classification level one stage lower than the current group classification level.

changing the display, if the scroll speed is less than a second predetermined value from scroll-displaying the first set of images representing the groups into which the plurality of content items are allocated to scroll-displaying the plurality of content items in a second order which is different from the first order such that the plurality of content items allocated into the same group of the first groups according to the attribute information which is different from the time information are displayed sequentially and adjacent to each other.

11. A non-transitory computer readable medium containing computer-executable instructions for allocating the plurality of content items scroll-displayed in a first order into a plurality of groups according to attribute information associated with the content items:

instructions for storing the plurality of content items and time information corresponding to each of the plurality of content items;
