An electronic endoscope apparatus whereby a picture image can be displayed at any desired displaying view angle irrespective of the pixel formation of a solid state imaging device, the picture image magnification rate and contraction rate of an observed object and the television broadcasting system comprises an imaging apparatus having a solid state imaging device outputting an object image as an electric signal and a video signal processing circuit driving the solid state imaging device and processing the read out electric signal to produce a video signal. The object image imaged by the solid state imaging device will be magnified or contracted by a picture image displaying magnification rate varying apparatus which can either magnify or contract the object image in at least one of the vertical direction and horizontal direction. The object image either magnified or contracted by the picture image displaying magnification rate varying apparatus will be displayed by a monitor. The view angle of the picture image displayed in the monitor will be adjusted by a picture image displaying magnification rate controlling apparatus which can control the magnification rate independently in at least one of the vertical direction and horizontal direction. The picture image displaying magnification rate controlling apparatus has a sensing and instructing apparatus sensing or instructing the factor varying the displaying view angle and outputting a signal relating to the picture image displaying magnification rate to the picture image displaying magnification rate controlling apparatus.
