Abstract
PURPOSE:To ensure high adaptability responding to a change of the pickup conditions, by securing switching for the reading period of a video signal supplied from a photoelectric transducer of a solid-state pickup device in accordance with the pickup conditions. CONSTITUTION:When a subject has a sufficient luminous intensity, switches 27 and 28 are at the positions as shown in the figure by the function of a light quantity detecting circuit 23. A solid-state pickup device 1 receives a horizontal scan by the pulse (a) with every field and delivers a video signal (g). The signal (g) is outputted G as it is through a preamplifier. When the luminous intensity of the subject is low, the switches 27 and 28 are interexchanged. Thus the device 1 receives a horizontal scan by the pulse (a') with every 2nd field, and the video signal is added with the signal delayed by a field delay line 22 through an adder circuit 29 to output G.
