WIDE APERTURE IMAGE SENSOR PIXEL |
摘要 |
<p>An image sensor includes a unit cell of four pixels. The unit cell includes four photosensitive regions that collect charge in response to light; four transfer transistors that respectively pass the charge from each of the four photosensitive regions to one common charge-to-voltage conversion mechanism; three control wires in which a first control wire controls two of the transfer transistors and a second control wire controls one of the transfer transistors and a third control wire controls one of the transfer transistors; an amplifier connected to the common charge-to-voltage conversion mechanism that outputs an output signal in response to a signal from the charge-to-voltage conversion mechanism; and a reset transistor connected to the common charge-to-voltage conversion mechanism for resetting the charge-to-voltage conversion mechanism to a predetermined signal level.</p> |
