1. An apparatus for operating objects that operates an object on a screen based on an imaged operating element, the apparatus comprising:

  • a computing apparatus;

    a display apparatus connected to the computing apparatus; and

    an imaging apparatus connected to the computing apparatus, whereinthe imaging apparatus images a predetermined operating element and the computing apparatus displays, as a marker, an image of the imaged operating element on the display apparatus, andthe object on the screen of the display apparatus is operated by movement of the marker, and whereinthe computing apparatus generates a bitmap B(x, y) in a pixel unit from digital image frame data imaged by the imaging apparatus, focusing on image properties including a predetermined H (Hue), S (Saturation), and V (Value),represents presence of a bit at each y value in the bitmap B(x, y) by a segment element (x, y, w) having a starting point (x) and a width (w),determines whether there is a contact relationship between the segment elements and puts together segment elements having a contact relationship into a matter element, andgenerates the marker based on the matter element.
