Abstract
A solid state color imaging apparatus includes a solid state image sensor having a plurality of picture elements regularly disposed in a two dimensional pattern along a plurality of horizontal lines. Each horizontal line includes a plurality of picture elements disposed in repetition at a predetermined pitch wherein light incident thereon is converted to a proportional electrical signal. A color filter placed over the picture elements has a plurality of filter elements disposed in regular repetition in horizontal rows and vertical columns. The filter elements are the same kind in each horizontal row scanned sequentially and only the combination is different. When the electric signals are read out from the imaging sensor, each horizontal row of filter elements spatially modulate at least two primary color lights. The mean value of the read out signals is equal and the modulated color signal is the color difference signal. The arrangement of the color filter elements are shown in three different alternative patterns, each for the purpose of attaining high-horizontal resolution, high S/N ratio and simplified signal processing.
