Abstract
Abstract A color filter arrangement having complementary color filters for mounting on an image pickup having a plurality of picture elements. The color filters are arranged to overlie respective picture elements and are further arranged to overlap each other over boundaries between respective picture elements with widths wider than the boundaries between the respective picture elements, thereby offsetting any misalignment of the filter arrangement during cementing. Also, an image pickup device including an image pickup arrangement for converting an optical image into electrical image information, the pickup arrangement having a plurality of picture elements including first and second picture elements, and the pickup device further including a color filter member at least consisting of a first part which is provided for the first picture element.
