Abstract
A solid-state image pickup unit in which two neighboring horizontal lines are paired for scanning. In the vertical transfer, the photocharge signals on the two lines are transferred to different horizontal CCDs, which concurrently shift out their contents. One of the two horizontal lines is used exclusively for a luminance signal and the other for two color signals. The horizontal line used for color signals has alternating color filters. A switch is used to separate the two color signals resulting from these alternating color filters.
