Light responsive elements of a color imaging array are arranged in basic groupings of four aligned elements, which groupings included two luminance-responsive elements that alternate with individual elements for two other basic colors. These groupings are repeated along a line and are shifted by one element in each adjacent line. As a result of intermixing color-responsive elements in this way, high-spatial-frequency luminance sampling is achieved for all directions on the array and closely repeated patterns of elements are achieved for all three basic colors in both fields of the array (here assuming a two-field interlaced readout array). Because closely repeated sampling occurs for all colors in both fields of such an array, the field-to-field color flicker, that can occur when intermixed color sampling is attempted using an interlaced-readout imaging array, is avoided.

A color imaging device comprising a rectangular array of interrogable photoelectric elements, such elements being selectively responsive to respective colors which correspond to a preselected three color basis, one color of which corresponds essentially to luminance; said elements being arranged in a configuration wherein alignments along one major dimension of the array consist essentially of a repeated four element grouping having two luminance-responsive elements alternating with elements responsive respectively to the other two colors of said basis, each successive such alignment being shifted by one element position but otherwise having substantially the same color pattern.
