Abstract

PURPOSE: To simplify the structure greatly as well as to increase the accuracy for the telecine device by performing the field scanning via the linear beams.
CONSTITUTION: The light given from spot 7 of flying spot tube 1 is converted to line 8 in the horizontal direction via semicylindrical lens 2, and the light on line 8 is irradiated onto film 3. Scanner 6 performs the horizontal scanning while line 8 has a scanning in 1/60 sec. from the upper end to the lower end of frame 4a of film 3. Thus, the TV video signal which is equivalent to 1 field and contains the informations according to the picture of frame 4a can be obtained through scanner 6. Then the 2-field video signal is obtained by scanning frame 4a twice at line 8, and then the 3-field video signal is obtained by scanning next frame 4b three times via line 8. After this, the scannings are performed alternaltely in the same way in order to secure synchronization between the frame of film 3 and the TV field
