Image pick-up apparatus for outputting image frames by thinning out the same |
摘要 |
An invalid frame in 60P images supplied from a 60P camera head is delayed by a single frame by a 1-frame delay circuit. A differential between the delayed invalid frame and the valid frame is computed by a subtracting circuit. Of the differential signal, only a portion over a predetermined value is picked out by a level filter. The picked out signal is attenuated to ½ by a ½ attenuator. By adding that attenuated signal to the valid frame by an adder, the invalid frame is superimposed on that valid frame. As a result, a natural picture is obtained.
