Abstract

PURPOSE:To prevent blooming, by transferring the charge of the 1st vertical register to a charge absorbing section, within the period when signal charge is moved from the storage area to the 1st vertical CCD register in the vertical blanking period. CONSTITUTION:In the NTSC system, a vertical blanking period is about 1,100musec and the initial vertical blanking period is about 500musec, and when the clock frequency of inversed transfer of the 1st vertical CCD register 2 is about 2MHz, then the inversed transfer should be about 1,000 bits. Since the 1st vertical CCD register 2 consists of transfer stages of about 250-bit, most of flowing charge is inversely transferred to the charge absorbing section. When the transfer gate 3 is on-state, almost no flowing charge is left in the 1st vertical CCD register 2 to prevent blooming phenomenon.
