SOLID STATE IMAGE SENSOR WITH HIGH RESOLUTION

摘要

There is disclosed a solid state image sensor including an interline transfer charge coupled device (IT-CCD) serving as an area image sensor and a vibrating plate for vibrating or swinging the IT-CCD in a plane orthogonal to an incident image light, horizontally, periodically and relatively to the incident image light in a given vibration mode. When the solid state image sensor is applied for NTSC television system in which one frame is composed of two fields, the IT-CCD is vibrated so that it senses an image at different positions during the two fields periods. As a result, a reproduced picture has a resolution which is obtained as if the number of picture elements of the image sensor per se is doubled.
