Claim:
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 number-of-points detecting section configured to detect whether or not two operating points has been substantially concurrently detected by the operating point detecting section; a first movement information detecting section configured, when the two operating points are detected by the number-of-points detecting section, operating points forming coordinate points continuous from an initial point which is one of the two detected operating points are successively detected by the operating point detecting section, and the successive detection of the operating points is then stopped, to detect first movement information indicating an amount of movement from the initial point to a primary stopping point where the successive detection is stopped; a second movement information detecting section configured, when the two operating points are detected by the number-of-points detecting section, operating points forming coordinate points continuous from an initial point which is the other of the two detected operating points are successively detected by the operating point detecting section, and the successive detection of the operating points is then stopped, to detect second movement information indicating an amount of movement from the initial point to a primary stopping point where the successive detection is stopped; an amount-of-value-change calculating section configured to calculate, from the amount of movement detected by the first movement information detecting 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 the amount of movement detected by the second movement information detecting 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 succession 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.
