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) (10) serving as an area image sensor and a vibrating plate (12) for vibrating or swinging the IT-CCD (10) in a plane orthogonal to an incident image light (16), horizontally (18), periodically and relatively to the incident image light (16) in a given vibration mode. When the solid stage image sensor (10) is applied for NTSC television system in which one frame is composed of two fields, the IT-CCD (10) 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 (10) per se is doubled.
