Display apparatus and computer readable medium

A non-transitory computer readable medium storing a program causing a computer to execute a process for image processing, the process comprising:

• generating a menu image in which selection items of a menu are geometrically arranged;
• and
• making the menu image be displayed on a screen of a display, and making positions of the selection items in the menu image dynamically changed,
• the process further comprising:
• generating the menu image separately for each layer of the menu set in a hierarchy,
• making the menu image of a lower layer be displayed on the screen of the display when the selection item associated with the lower layer is selected among the selection items comprised in the displayed menu image, and makings the menu image of a higher layer from which the selection item was selected be displayed in a manner that indicates that selection items of the higher layer are not currently selectable, and
• recognizing a position of an object image displayed on the screen of the display, and determining a display position of the menu image so as not to overlap the object image with the menu image, wherein
• the selection items are arranged in a circular pattern,
• the positions of the selection items arranged in the circular pattern are rotated and moved around a center of the circular pattern,
• when the lower layer is displayed, a rotation of the menu image of the higher layer than the layer that is displayed at the last is stopped, and
• when one of the circularly arranged selection items is selected, selection items of the lower layer are linearly arranged with the selected selection item as a base point, and
• the menu image is displayed at the determined display position.
