Abstract
The invention provides a synchronizing conversion apparatus wherein outpacing compensation can be executed with a circuit construction including a comparatively small number of components. A read control circuit produces a read control signal including a read address and a read timing based on an outpacing detection signal from a phase comparison circuit, which is generated taking a time required for processing of a memory access arbitration circuit into consideration, and a scene change detection signal from a scene change detection circuit. The read control signal is outputted to the memory access arbitration circuit. The memory access arbitration circuit arbitrates requests from a write control circuit and the read control circuit to control writing into and reading out from a frame memory.
