| abstract |
This invention is to stabilize and secure a data transfer band between a first memory and a second memory to enhance efficiency in the use of the data transfer band. The brightness signals Ya and color-difference signals Ua/Va that constitute input image signals Sa are transferred to and written in a frame memory (a first memory) 201 in lines in sync with their horizontal synchronizing signals. A memory TG 211 generates a readout request PRQ. A period of the request PRQ is a time obtained by dividing equally one vertical effective period of output image signals Sc by a line number for serving as a target of the rate conversion of the input image signals Sa. On the basis of the request PRQ, the brightness signals Ya and the color-difference signals Ua/Va are transferred in lines from the frame memory (the first memory) 201 to a rate conversion section (a second memory) 215Y, 215C through buffers 205Y, 205C. As no variation in the transfer period occurs, the data transfer band can be stabilized and secured in each of transfer periods. |
