Abstract
An image pickup apparatus operated in mode-1 in which signal-charge that is charged in a CCD imaging device is read out as the output signal of the CCD imaging device once in each field of progressive-scanning, or in mode-2 in which the signal-charge is read out once (viz. during one field) in every two fields of progressive-scanning. And the output signal of the CCD imaging device is written into a memory according to a progressive-scanning synchronizing signal during the intervals when the signal-charge is read out. Then the signal written in the memory is read out, in the mode-1, according to the progressive-scanning synchronizing signal, and, in the mode-2, in such a manner that odd lines are read out in each odd field and even lines are read out in each even field according to an interlaced-scanning synchronizing signal. The above structure enables the image pickup apparatus to have simple circuit, good performance, and to be usable for at least the two modes of the 525/60P mode and the 525/30P mode.
