Disclosed is a solid state television camera with solid state image sensor for converting an optical image into electrical signals, which is comprised of a pulse generator for generating a train of pulses with a frequency equal to the horizontal scanning frequency of a television system, a frequency divider for frequency-dividing the pulse train into a signal with a frequency substantially equal to the vertical scanning frequency alternately in two modes of l/n and l/n+l (where n is a positive integer), and a selective circuitry for forming a train of pulses with a desired vertical scanning frequency on the basis of the pulse trains derived from the pulse generator and the frequency divider.
