1. A microscope apparatus comprising:

  • a light source;

    an illumination optical system for introducing light from said light source to an object;

    an imaging optical system for obtaining an image of the object;

    means for separating the light from said light source into two portions, disposed in said illumination optical system; and

    means for superimposing said two portions of the light on one another, disposed in said imaging optical system;

    wherein said microscope apparatus further comprises;

    an electronic image pickup device arranged on an image surface of said imaging optical system;

    means for changing a phase difference between said two portions of the light;

    means for storing images picked up by said electronic image pickup device; and

    means for processing information on the images picked up by said electronic image pickup device;

    wherein the images are picked up by said electronic image pickup device as the phase difference is changed, to be stored as picked-up image information, and said picked-up image information is subjected to an integration process, upon being multiplied by a periodic function, as a weight function, which is given the phase difference as a variable, to produce final process image information.
