摘要： The signal charge corresponding to the amount of light is obtained from a photodiode section and is then stored in a charge storage section under the control of a first control gate. An additional charge storage section may be provided between the photodiode section and the charge storage section. The signal charge thus stored in the charge storage section is supplied to a charge transfer section under the control of a second control gate. The charge storage section is set to operate in a PIN-ing state during its operation, which may be carried out by, for example, covering an N-type region with a storage control electrode to which a predetermined DC bias voltage is applied, or by forming a P-type region in surface portion of the N-type region.

摘要： In an autofocus image sensor, monitoring pixels are disposed adjacent to a pixel array over a length equal to that of the pixel array in each of a standard portion and a reference portion. Signals from the monitoring pixels of both of the standard portion and the reference portion are subjected to arithmetic operation to control accumulation of electric charges. Thus, an error in position detection is minimized.
