Claim 3:
4. The method according to claim 1, further comprising performing, in a color read-out mode, a transfer phase by:
emptying first photogenerated charge from the first doped photosensitive region by transferring said first photogenerated charge to said upper portion of the first doped photosensitive region through biasing of said first vertical annular gate;
transferring said first photogenerated charge to a read node through biasing of said vertical annular transfer gate;
emptying second photogenerated charge from the second doped photosensitive region by transferring said second photogenerated charge to said first doped photosensitive region through biasing of said second vertical annular gate;
emptying second photogenerated charge from the first doped photosensitive region by transferring said second photogenerated charge to said upper portion of the first doped photosensitive region through biasing of said first vertical annular gate; and
transferring said second photogenerated charge to the read node through biasing of said vertical annular transfer gate.
