Abstract:
When a first display device displays image data, a display control apparatus reserves a memory space having the first horizontal pixel number in the storage unit, and sets the frequency of a clock signal supplied to the display control unit to a first frequency. When a second display device displays image data, a display control apparatus reserves a space of the second horizontal pixel number, which is higher than the first horizontal pixel number, and sets the frequency of a clock signal supplied to the display control unit to a second frequency which is higher than the first frequency.
