A color imaging apparatus having a plurality of image pickup tubes which pick up respective optical images of primary colors separated from one optical image includes a registration control circuit which operates to hold a picture of high quality at all times by controlling the registration of the images of the respective image pickup tubes on a real time basis during the operation of the camera. To this end a circuit detects those local image signals which satisfy predetermined requisites which are most favorable for use as reference signals to control the registration and these detected image signals are temporarily stored so as to be used for the registration operation. The most favorable requisites of the local image areas selected for registration control are (1) those having no movement, (2) those having a contour which is sharp and (3) those having a chroma which is low.
