Abstract:
1. A display device which enlarges an image represented by image signals to be displayed comprising: a memory which is arranged to store said image signals; a display panel which displays said image represented by said image signals; a processing circuit which enlarges said image signal by a non-integer number of times in accordance with a resolution of said display panel divided by a resolution of said image represented by said image signals; and a control circuit which inputs said image signals into said memory in accordance with first horizontal synchronizing signals which have been inputted together with said image signals, and outputs said image signals from said memory in accordance with second horizontal synchronizing signals synchronized with said first horizontal synchronizing signals, wherein said control circuit synchronizes said second horizontal synchronizing signals with said first horizontal synchronizing signals, every time one of said first horizontal synchronizing signals is generated M times and one of said second horizontal synchronizing signals is generated N times, N is not equal to M, N divided by M is a non-integer number, N divided by M corresponds to the resolution of said display panel divided by the resolution of said image represented by said image signals, and a generation cycle of one of said second horizontal synchronizing signals is almost constant.
