Abstract: High-order bits to be utilized for current-frame display data and previous-frame display data, and low-order bits to be utilized for the current-frame display data alone are stored in independently controllable memory areas. For reading the current-frame display data from a frame memory, data of the high-order bits and data of the low-order bits are read. For reading the previous-frame data, the high-order bits alone are read. Thus, since a period during which the data of the low-order bits that is not utilized for the previous-frame display data is stored in the memory is shortened, a required memory capacity can be reduced. The data transfer time can be reduced by the time required for memory read for the data of the low-order bits that is not utilized for the previous-frame display data.
