Abstract
A video signal reproducing method and apparatus are arranged to improve a retrieval characteristic and alleviate fatigue and discomfort of a user at a fast reproduction mode and further magnify the reproduction speed more. In the video signal reproducing apparatus, a fast reproducing circuit 15 synthesizes the picture data written in memories 21 and 22 for generating data of a middle picture in the case of outputting the picture data of one screen written in the memories 21 and 22. Then, the circuit 15 inserts the data of the middle picture between the picture data for generating the output picture at a fast reproduction speed. The data of the middle picture is generated by adding the picture data of both memories at a ratio set by a main control unit. This ratio is a coefficient K (0.ltoreq.K.ltoreq.1) and is given as a value of (1-K) to a first multiplier 25, while it is given as a value of K to a second multiplier 26. The value of (1-K) is multiplied by the picture data of each memory by the first multiplier. The value of K is multiplied by the picture data of each memory by the second multiplier. The results of the multipliers are added by the adder 27. Then, the added result is fed out of the reproducing apparatus.
