Full picture element read single board solid-state image pickup device

Abstract

Abstract PURPOSE:To prevent production of brightness flicker and lateral stripe and to obtain a luminance signal without a false signal by implementing coding of a full picture element read solid-state image pickup element in the unit of 2X2, using three colors able to be separated for the coding, arranging one color of them on two picture elements of a check lattice or a rectangular lattice and forming a vertical aperture control signal from the color signal. CONSTITUTION:Captions A0, A1, B, C indicate three color filters able to be separated and the A0, A1 are filters of the same color. A color A is arranged to two positions of a rectangular lattice as A0, A1 and colors B, C are arranged to the remaining two positions respectively. Then a vertical aperture control signal Yvap is generated by using the signals of the color A only. Captions 1a0, 1a1, 1b, 1c are amplifiers to amplify the color signals A0, A1, B, C sampled- and-held by a sample-and-hold circuit (not shown) and a caption 2 is an adder circuit adding outputs of the amplifiers 1a0, 1a1, 1b, 1c to generate a luminance signal Yv1 (vertical low frequency component). A vertical aperture control circuit 3 generates a vertical aperture control signal Yvap [=alpha(A0+A1)].
