Then, in synchronization with this time, the vertical synchronization counter (hereinafter, VD _num ) is cleared (= 0) in step S63, the half image data 123 is read in steps S64 and S65, and the screen image is displayed. When the transfer of the upper half of the screen (up to the 127th line) is completed, the process proceeds to step S66 to check the current count number of VD _num .

If VD _num <30 (1/2 second before the start), the half image data 124 is read in steps S67 and S68 and transferred to the lower half of the screen screen, and VD _num +1 is set in step S72. , And returns from step S73, S75 to step S64. 30 ≦
If VD _num <60 (between 1/2 second and 1 second), the half image data 125 is read in steps S69 and S70 and transferred to the lower half of the screen screen, and VD _num +1 is set in step S72, and the step is performed. S73, S7
It returns from 5 to step S64.

If 60≤VD _num <90 (between 1 second and 3/2 seconds), the half image data 126 is read out in step S71 and transferred to the lower half of the screen screen, and VD _num +1 in step S72. As step S
