1. A display apparatus comprising:

  • a display section configured to display an image;

    a display control section configured to control a display operation of the display section;

    an operating point detecting section configured to detect an operating point where an operator has performed an operation on a display screen of the display section;

    a movement information detecting section configured, when the operating point as an initial point and the operating points forming coordinate points continuous from the initial point are successively detected by the operating point detecting section and the successive detection of the operating points is then stopped, to detect movement information indicating a direction and an amount of movement from the initial point to a stopping point where the successive detection is stopped;

    a vector calculating section configured to divide a vector indicated by the movement information detected by the movement information detecting section into components in predetermined x and y directions and thus calculate the components as respective component vectors in the x and y directions;

    an amount-of-value-change calculating section configured to calculate, from an amount of movement indicated by the component vector in the y direction calculated by the vector calculating section, a predetermined increment used as an amount of numerical value change at each display switch so that the display control section allows the display section to switch a display from one to another of a plurality of numerical values in succession in increasing or decreasing order; and

    a switching speed calculating section configured to calculate, from an amount of movement indicated by the component vector in the x direction calculated by the vector calculating section, a display period of each of the plurality of numerical values used as a switching speed at each display switch so that the display control section allows the display section to switch the display from one to another of the plurality of numerical values in the amount of numerical value change,wherein the display control section is further configured to allow the display section to switch the display from one to another of the plurality of numerical values in succession in the calculated amount of numerical value change and use the calculated switching speed as the switching speed at the display switch from one to another of the plurality of numerical values.
