摘要： In an image pickup apparatus used for interlaced scan, slow motion video, the prior art has had the problem that the slow motion video suffers a vertical phase shift or becomes discontinuous in time.
The invention comprises: video storing means 2 of recording and playing back the sequential scan video signal captured by a sequential scan image pickup means 1 through a light input 100 and output from the sequential scan image pickup means 1 for i frames (i is an integer not smaller than 1) over a period of time T1 (T1 is a positive number); and sequential scan/interlaced scan converting means 3 of generating an interlaced scan video signal for m fields (m is an integer not smaller than 2) from each frame of the played back i-frame sequential scan video signal, wherein the interlaced scan video signal is output for i × m fields over a period of time T2 (T2 is a number larger than T1).
