A dual layered image sensor 2 has a photosensitive layer 21 and an electronic charge transfer layer 22 which has a horizontal transfer gate 23 being connected to an output 24. In such structured image sensor 2, Z transfer which transfers electronic charges from the photosensitive layer 21 to the electronic charge transfer layer 22, and X-Y transfer which transfers the electronic charges in the electronic charge transfer layer 22 in X-Y directions are available. The image sensor 2 is driven to execute a plurality of exposures during an exposure term for image capturing. At each exposure, the photosensitive layer 21 accumulates electronic charges and transfers the accumulated electronic charges to the electronic charge transfer layer 22. Simultaneous with each exposure except 1st one, all electronic charges in the electronic charge transfer layer 22 transferred during the former exposure are transferred in X-Y directions inverse to the directions of shakes on the apparatus body, thus the transferred electronic charges form a blur compensated image. Then, the electronic charges accumulated in the electronic charge transfer layer 22 are obtained line by line via the horizontal transfer gate 23 and the output 24.
An imaging apparatus having a function for preventing blurry images caused by shaken apparatus body, comprising:
A solid image sensor for converting an optical image into image signals by photoelectric conversion, comprising:
A method for driving a solid image sensor having an electronic charge transferor which comprises 2-dimentionally arrayed multiple electronic charge coupling elements having specific electronic charge coupling elements which accumulate electronic charges of each pixel in an optical image generated by photoelectric conversion, and a horizontal transferor which obtains the accumulated electronic charges in said electronic charge transferor line by line as an image signal, comprising the steps of:
