Abstract
A first video signal having a first frame rate optionally settable is generated by an image pickup device, and the first video signal is memorized in a memory and outputted from the memory. A write control device controls the write of the first video signal with respect to the memory, and a read control device controls the read of the video signal with respect to the memory. The write control device writes respective first frame data constituting the first video signal in the memory in each cycle determined by the first frame rate of the first video signal. The read control device reads the first frame data as a second video signal. The second video signal is formed from sequentially arranging the first frame data in a partially duplicating manner in a standard video signal having a standard frame rate based on a determined arrangement rule. The predetermined arrangement rule is an arrangement rule employed when respective frame data constituting a video signal having a second frame rate equal to or lower than the standard frame rate are arranged in a duplicating manner in the standard video signal. In the foregoing manner, an time elongation/contraction effect on an image can be s…
