Document Type and Number:
Japanese Patent JP4236864
Kind Code:
B2
Abstract:
A color image sensor includes a plurality of image elements, a plurality of read gate sections, a plurality of vertical scanning charge transfer sections, and a plurality of transfer switch sections. The plurality of image elements are arranged in a matrix of rows and columns and each of the plurality of image elements generates an electric charge in response to incidence of light. The plurality of read gate sections are provided for the plurality of image elements, and each of the plurality of image elements controls transfer of the electric charge generated in a corresponding one of the plurality of image elements. Each of the plurality of vertical scanning charge transfer sections is provided for every column of the matrix to hold and transfer the electric charges transferred from a corresponding column of the plurality of read gate sections. Each of the plurality of transfer switch sections is provided for a termination section of a corresponding one of the plurality of vertical scanning charge transfer sections to control transfer of the electric charges from the corresponding vertical scanning charge transfer section.
