专利汇可以提供Reproducing method of picture scan专利检索,专利查询,专利分析的服务。并且PURPOSE: To hold the picture signal of the preceding period in some form and in parallel to the picture signal of the subsequent period and to synthesize these two types of picture signals to deliver them in the form of a recording signal in case when the reading is carried out to the recording side.
CONSTITUTION: An X memory device 34 records the picture signal d
2 while securing the synchronization between the start pulse g
6 and the first address and also changing the address successively in accordance with the writing pulse g
9 . A Y memory device 35 records the signal d
2 in parallel to the device 34 only in case when the signal g
9 is obtained through an AND gate 37. The read data d
x and d
y of both devices 34 and 35 are held in latch circuits 40 and 41 respectively by the read pulse g
7 . Only a data switch 42 of the device 34 side opens the bus line and transmits the data d
x of the circuit 40 to a D/A converter 56 by the thinning signal g
12 of a low level delivered from a thinning detecting circuit 44. The data switch signal g
13 is read alternately by the pulse g
7 if the signal g
13 passes through the gates 52 and 53.
