    • A still video camera comprising a memory circuit storing an ordinary automatic exposure program chart and another automatic exposure program chart suited to a flickering light source, a judging circuit for determining, prior to image sensing, whether or not a light source related to an object to be photographed is the flickering light source, an automatic white balance adjusting circuit for forming an automatic white balance adjusting signal prior to image sensing, and adjusting the white balance of a video signal obtained by image sensing on the basis of the automatic white balance adjusting signal, a selecting circuit responsive to that output of the judging circuit which represents that the light source related to the object is not the flickering light source for selecting the ordinary automatic exposure program chart from the memory circuit or responsive to that output of the judging circuit which represents that the light source related to the object is the flickering light source for selecting the automatic exposure program chart suited to the flickering light source, and an automatic exposure determining circuit for deriving value of the aperture size and the shutter speed to be used in making an exposure by computation based on the automatic exposure program chart selected by the selecting circuit.
