1. An image processing system which comprises an image processor which generates image data of an image to be displayed on a monitor, and an analog joystick, comprising:

  • a joystick lever which is inclined within an inclinable range when said lever is operated by an operator and rests at a predetermined state indicative of a center of a coordinate reference frame if said lever is not operated by the operator;

    inclined amount data output circuitry which outputs inclined amount data according to an inclined amount of said lever; and

    an image processor being operable to determine on the basis of said inclined amount data whether or not said lever exists within a dead area of said coordinate reference frame including the center;

    said image processor being operable to perform a first correction operation to correct said inclined amount data to center data indicative of said center when it is determined that said lever exists within said dead area;

    said image processor being operable to perform a second correction operation to correct said inclined amount data on the basis of an inclined amount equal to a distance from said center to said dead area when it determines that said lever exists outside said dead area; and

    said image processor being operable to output image data on the basis of inclined amount data which is corrected by said first correction operation when said lever exists within said dead area, or on the basis of inclined amount data which is corrected by said second correction operation when said lever exists outside said dead area.
