  • Patent number: 7773075
    Abstract: A touch location detection section (103) detects the location on a display screen where the operator's finger touches. A transfer length calculation section (104) calculates the transfer length La of the operator's finger from the touch start location S to the touch end location E. A transfer length judgment section (105) judges whether or not the transfer length La is greater than a reference transfer length Ls. A location shift calculation section (106) calculates the location shift ? of the operator's finger. A location shift judgment section (107) judges whether or not the location shift ? is less than a predetermined reference location shift ?s. When La>Ls and ?<?s, a screen split control section (108) controls the operation of an image display section so as to split a display screen 101.
