Field Integration Mode Frequency Interleaving Method for Single Chip CCD Color Camera

Abstract

A field integration mode frequency interleaving method for CCD color video camera has been studied.
The frequency interleaving is one of the signal processing methods used in the conventional single tube color camera system, and color separation circuit becomes very simple. Furthermore, the field integration mode operation has some superior points, such as no field time lag, wide anti-blooming properties and so on. The color filter arrangements for this operation have been investigated and the existence of 100 varieties was shown. A new color mosaic filter array, consisting of three colors, white, yellow and cyan, was selected out of 100 geometries. Fine picture quality with no field time lag and little moire effect could be obtained.
