ABSTRACT:
A solid-state image sensing device, such as an interline-transfer type charge-coupled device (IT-CCD), produces signal carriers in response to incident light and generates an image pickup signal. One frame of the image signal is formed of two fields. The CCD chip is coupled to fixed bimorph piezoelectric vibrators by which it is given a wobbling-swing drive during image pickup. This wobbling-swing drive is controlled by a vibration controller. This vibration controller controls the vibration mode of the bimorph piezoelectric elements to apply a first vibration (swing vibration) to the CCD such that each pixel cell is displaced to a different sampling position in the plurality of field periods included in one frame period for image pickup, and applying a second vibration, i.e., a swing vibration with wobbling superposed, to the CCD such that each pixel cell is wobbled while picking up an image in each sampling position, which is positioned in each field period.
