Abstract
In a solid state image sensor of the type which employs an inter-line transfer charge-coupled imaging device, the electrodes of the vertical shift registers are enlarged to extend to places which lie between image pick-up portions aligned in the vertical direction of the device. Each of the image pick-up portions comprises an image sensing area and a transfer gate. Preferably, every other image pick-up portion of a conventional CCD imaging device is removed to provide spacing between the image pick-up portions relative to the vertical direction.
Claims10
A solid state image sensor employing charge transfer devices comprising:
- a. a plurality of image pickup portions aligned in two dimensions in areas of a semiconductor body, each image pickup portion having an image storing area and a transfer gate area;
- b. a plurality of vertical shift registers extending adjacent said image pickup portions in the vertical direction, each vertical shift register having a plurality of electrode sets having enlarged portions which lie between said image pickup portions relative to the vertical direction;
- and
- c. a horizontal register for receiving collected light information from said plurality of vertical shift registers in parallel and for supplying the light information in a serial form to an output.
A solid state image sensor adapted for using charge coupled transfer devices, comprising:
- a. a semiconductor body;
- b. image pickup means arranged in parallel columns on said semiconductor body;
- c. vertical shift register means adjacent said columns of image pickup means, said vertical shift register means comprising a plurality of electrode sets, each electrode set comprising first and second electrodes which extend between at least some of the image pickup means in said columns;
- and
- d. horizontal register means on said semiconductor body for receiving collected light information from said vertical shift register means and for supplying said light information in serial form to an output.
