Claim:
1. A memory control device that performs (a) a write-in operation for writing, to a frame memory, data transferred from a host and (b) a read-out operation for reading the data written in the frame memory and then transferring this data to display control circuitry, the memory control device comprising: write-in start position control circuitry that performs a process of shifting, by a given shifting amount, a start position of the write-in operation to the frame memory, the given shifting amount being predetermined so as not to exceed a capacity reserved in advance in the frame memory in a case where (i) a read-out period from a start to an end of the read-out operation is different in length from a write-in period from a start to an end of the write-in operation and (ii) the write-in operation is started; wherein the frame memory is a single memory which stores image data corresponding to one frame, and the frame memory has a storage capacity that is extended by at least the shifting amount beyond a storage capacity for 1 frame of the data.
