1. A solid state imaging device comprising:

  • an imaging semiconductor chip for outputting an analog image signal in which all transistors are formed of the same conductivity type; and

    an image processing semiconductor chip, to which the analog image signal is input, comprising CMOS transistors,wherein the imaging semiconductor chip comprises;

    a photoelectric converter for converting light into an electric signal; and

    an amplifier for amplifying the electric signal generated by the photoelectric converter, andwherein the image processing semiconductor chip comprises;

    an AD converter for converting the analog image signal output from the imaging semiconductor ship into a digital signal; and

    an image processing circuit for performing image processing based on the digital signal converted by the AD converter.
