ABSTRACT:
A camera wherein a subject to be taken is pure-electronically still-photographed and recorded, and an image is reproduced by a television system and a printer. Resolution of the camera of this type is lower than that of the ordinary cameras. Accordingly, during the portrait photographing, it is necessary that the ratio of the face occupying in the taking background is made to be beyond a predetermined value. Then, when the taking distance is beyond a predetermined value, a warning is issued to call a photographer's attention to a close-in taking or automatically zoom-up.
