ABSTRACT:
A pulse generator circuit for a solid-state television camera comprising a first circuit arrangement including a shift register of endless type for obtaining pulses of a horizontal scanning frequency for television, a second circuit arrangement for obtaining necessary pulse trains of the horizontal scanning frequency for a television camera from a plurality of output pulses of the shift register and a third circuit arrangement for dividing the pulse obtained by the second circuit arrangement by two-different factors of mode, n and n+1, and delaying the 1
frequency-divided mode pulse by 1/2 horizontal scanning period in response to the output pulse from the second circuit arrangement thereby obtaining a frame pulse capable of interlaced scanning.
