ABSTRACT:
An image pick-up apparatus includes an image sensing device which converts an optical image into an electrical signal, the image sensing device including a photoelectric conversion part and a vertical transfer part. A mode switching device switches an operation mode between a frame mode and field mode. Also included is a control device which controls the bias level and/or timing of a vertical transfer pulse depending on the operation mode selected via the mode switching device. The control device provides a predetermined amount of shift to an intermediate level of a transfer pulse used to drive a vertical transfer part adjacent to a photoelectric conversion part. The control means also provides the same amount of shift to intermediate levels of transfer pulses used to drive other vertical transfer parts. The control device further includes a plurality of shifting circuits which determine the amount of shift of the individual vertical transfer pulse, the plurality of shifting circuits being connected to a common power supply source.
