ABSTRACT:
A high sensitivity camera device is disclosed, in which two frame memories are assigned to a system which processes' picture signals from an image pickup element, the signals are written to the frame memories alternately as they are read, signals read from the two frame memories are multiplied respectively by coefficients K (K.ltoreq.1) and (1-K), and the results of the multiplication are added in an adder to be output. In this processing, the coefficients are changed for every frame or field, a weighted sum is taken to form a new frame or field by varying the ratio of addition according to the relationship between the read intervals, and a continuously changing picture is obtained. By employing the present invention it is possible to eliminate unnatural appearance of the motion of the objects in the picture by the use of two frame memories and two arithmetic circuits for which the addition coefficients can be controlled, even in the case of aiming at achieving high sensitivity by carrying out charge storage over the period which is an integral multiple of one frame or one field.
