A field integrating time is divided into a useless integrating time and a useful integrating time. The shorter one is the useful integrating time, the faster one is the electronic shutter speed. The useless integrated charges are cleared by the "photographic plate" clearing method. This image pickup camera apparatus is a high speed image pickup camera apparatus having low or slight high frame frequency, short explosure. A clear, relatively still or very slowly spinning images can be obtained by adjusting the field frequency of the high speed pickup camera apparatus.
