To present the operating state of a tracing operation in the event of performing a tracing operation to scroll objects of display. Upon a tracing operation being performed as to the operating face of an input detection device (i) provided on the display face of a display device (), coordinate information indicating he instructed position corresponding to the tracing operations is output from the input detection device (I). A user interface control unit () detects the operation direction and amount-of-operation with the starting position of the tracing operation as a reference, based on the coordinate information from the input detection device (i), and effects control so as to change the display mode of operating symbols displayed on the display screen of the display device ().

Information processing apparatus, information processing method and information processing program for performing a tracing operation

A display control apparatus includes an image creating section creating a first image having a predetermined number of drawing areas each onto which a thumbnail image is drawn, and an erasing section erasing at least one drawing area from the first image in response to an instruction from a user to display the first image. The number of drawing areas erased is the same as a number that is determined by subtracting the number of thumbnail images to be drawn in the first image from the predetermined number of drawing areas of the first image. The apparatus also includes a drawing section drawing a thumbnail image in each of the unerased drawing areas remaining in the first image, and a display controlling section controlling display of the first image including the thumbnail image drawn in each drawing area.
