ABSTRACT:
An external synchronism control circuit is triggered in synchronism with an external synchronous signal so as to successively generate addresses to an image memory storing image information. The external synchronism control circuit comprises a synchronism register receiving the external synchronous signal and capable for holding a plurality of set values. When the external synchronous signal is applied, the synchronism register is initialized to be set with an initial value of the plurality of set values. The content of the synchronism register is updated from one set value to another set value when a predetermined period of time has elapsed. When the content of the synchronism register is updated to a final value of the plurality of set values, the synchronism register operates to maintain the final value until a next external synchronous signal is applied. An address controlling circuit operates sequentially update the address to be supplied to the memory, from a period in which the synchronism register holds a predetermined set value of the plurality of set values until a period in which the synchronism register is in a condition of holding the final value, so that the updated address is supplied to the memory.
