1. An electronic still camera apparatus wherein an image of an object is exposed on an image pickup surface of image pickup means through an optical lens, the apparatus comprising:

  • first detection means having a two-dimensional photoelectric converter for receiving the image of the object exposed to the image pickup surface of the image pickup means, said first detection means outputting a detection signal representing a center of gravity of a light distribution of the image of the object;

    second detection means for detecting a variation of the center of gravity, on the basis of the detection signal output from said first detection means during an exposure of the image of the object;

    deviation correction means for moving at least one of said optical lens and said image pickup means in a direction perpendicular to an optical axis of said optical lens, so as to reduce the variation of the center of gravity to zero on the basis of an output from said second detection means; and

    wherein said two-dimensional photoelectric converter and the image pickup means are movable in a direction perpendicular to the optical axis of said optical lens as one body, and said deviation correction means includes means for moving the image pickup means and said two-dimensional photoelectric converter in a direction perpendicular to the optical axis of said optical lens so as to reduce the time variation of the center of gravity to zero on the basis of the output from said second detection means.
