Patent ID: 7233307

Claim:
A display control device for controlling an image display device, comprising: a controller configured to perform a first process for controlling said image display device in a cycle of one frame period and to perform a second process for controlling said image display device in a cycle different from one frame period and at an arbitrary timing; a storage comprising a first storage area and a second storage area; and a processor configured to write first control data for said first process to said first storage area, to write second control data for said second process to said second storage area, to transfer said first control data stored in the first storage area to said controller in a cycle of one frame period, and to transfer said second control data stored in the second storage area to said controller in a cycle different from one frame period and at an arbitrary timing; wherein said second process includes a static process for setting an operating state of said image display device based on a control signal supplied at an arbitrary timing and a refresh process for resetting the operating state set in the immediately preceding static process in the cycle different than the one frame period.
