Patent Searching and Data


Title:
【発明の名称】電荷結合装置及びこの装置を具えるカメラ
Document Type and Number:
Japanese Patent JP2677579
Kind Code:
B2
Abstract:
The invention relates to a charge-coupled image sensor arrangement, in which in the case of overexposure the excess of generated electrons is drained in vertical direction to the substrate. In order to adjust the maximum acceptable extent of overexposure, means are provided, with the aid of which an additional low voltage can be applied to the blocking gates. As a result, it is possible to adjust the maximum overexposure without the maximum white level being variable. Due to the fact that the said blocking voltage is a d.c. voltage, the dissipation substantially does not increase.
