Color solid image pickup device

Abstract

Abstract PURPOSE:To obtain a luminance signal and a modulation color signal by addition and subtraction between adjacent scanning lines, by arranging three-color filters so that the space modulation color signal may be inverted at 180 deg. for every one horizontal scanning and the light receiving output may be the same color signal in each vertical signal line. CONSTITUTION:The signal which is space-modulated through photo diodes 2a, 2a', 2a''... by RGB filters 6, 7 and 8 in the first horizontal scanning line is caused to pass through photo diodes 2b, 2b', 2b''... in the second scanning line to obtain a signal different in phase from the signal of the first horizontal scanning line by 180 deg.. Photo diodes are so arranged that the same color signal can be obtained in the same vertical transfer means. Consequently, a luminance signal and a modulation color signal can be obtained by addition and subtraction between signals of photo diode is 2a, 2a', 2a''... and 2b, 2b', 2b''... from adjacent scanning lines respectively.
