Abstract
A luminance signal Ya and a color-difference signal Ua/Va constituting an input image signal is transferred to a frame memory (first memory) in the unit of line synchronously with its horizontal synchronous signal and written therein. A memory TGreads out a read-out request RRQ. The cycle of this request RRQ is a time computed based on a single vertical effective period of an output image signal Sc and the number of lines objective for rate conversion of an input image signal Sa. The luminance signal Ya and color-difference signal Ua/Va are transferred in the unit of line from the frame memory to rate conversion units (second memory) through buffers. There occurs no deflection in this transfer cycle and in each transfer cycle, the stable data transmission band can be secured.
