ABSTRACT:
A control device includes a control mechanism for eliminating an effect of dark current generated in a CCD which may be, for example, provided in a still video system operated in a frame mode. The control mechanism controls the imaging device in such a manner that, after an aperture is closed, the imaging device outputs an image signal from a first field and an image signal from a second field, and then outputs data from a third field corresponding to a dark current component. The control mechanism thereafter subtracts the data of the third field from the image signal of the second field. The data obtained by this subtraction is outputted together with the image signal of the first field, as a one frame image signal.
