Patent Images

1. imageing sensor, it comprises:

  • A plurality of pixels, it comprises;

    The unit cell of four pixels, it comprises;

    A) four photosensitive regions, it collects electric charge in response to light;

    B) four are transmitted transistors, and it will be delivered to a share charge/voltage conversion mechanism respectively from each the described electric charge in described four photosensitive regions;

    C) first, second and third pilot, wherein said first pilot are controlled the one and the 3rd pilot that both and second pilot in the described transmission transistor control in the described transmission transistor and are controlled one in the described transmission transistor;

    D) transistor, it is connected to described share charge/voltage conversion mechanism, and described transient response is in from the signal of described charge/voltage switching mechanism and export an output signal;

    AndE) reset transistor, it is connected to described share charge/voltage conversion mechanism to be used for that described charge/voltage switching mechanism is reset to the prearranged signals level.
