PURPOSE:To obtain high resolution while excellently keeping sensibility by pairing a plurality of photosensitive pixel lines and acquiring the picture signal of one scanning line from a pair of signal charges in the photosensitive pixel lines. CONSTITUTION:Two lines of photosensitive pixels 21a, 21b are read simultaneously in an odd numbered field, two lines of the next picture elements 21c, 21d are removed, and two lines next to the two lines of the pixels 21c, 21d are read. Two lines of the photosensitive pixels 21c, 21d are read at the same time in an even numbered field. Four-phase clock pulses for one period are applied to a row-direction register for a vertical blanking period concretely, and signal charges are transferred up to transfer electrodes 25g, 25h and held. Read pulses pulses are applied to a transfer electrode 25a, and the signal charges of the photosensitive pixel 21a are transferred under transfer electrodes 25a, 25b. Four-phase clock pulses corresponding to two periods are applied to the row- direction register for a horizontal blanking period, and signal charges corresponding to two are respectively transferred to line-direction registers 23a and 23b. |
