Abstract
A precise position control apparatus and precise position control method using the same includes a control unit to control an amount of movement of a moving object, an optical system to photograph the moving object and to generate an image signal, and a monitor to output the image signal onto its screen. The control unit measures an actual moving distance of the moving object and a number of pixels corresponding to the actual moving distance to calculate an actual distance for unit pixel appearing on the screen of the monitor. Additionally, the control unit controls the amount of movement of the moving object using the actual distance for unit pixel when the moving object is moved from one position to another.

A precise position control apparatus, comprising:
- a control unit to control an amount of movement of a moving object;
- an optical system to photograph the moving object and to generate an image signal;
- and
- a monitor to output the image signal onto a screen thereof,
- wherein the control unit measures an actual moving distance of the moving object and a number of pixels corresponding to the actual moving distance to calculate an actual distance for unit pixel appearing on the screen of the monitor, and controls the amount of movement of the moving object using the actual distance for unit pixel when the moving object is moved from one position to another.
A precise position control method using a precise position control apparatus, the precise position control apparatus having a control unit to control an amount of movement of a moving object, an optical system to photograph the moving object and to generate an image signal, and a monitor to output the image signal onto a screen thereof, the method comprising:
- measuring an actual moving distance of the moving object and a number of pixels corresponding to the actual moving distance to calculate an actual distance for unit pixel appearing on the screen of the monitor;
- and
- controlling the amount of movement of the moving object using the actual distance for unit pixel when the moving object is moved from one position to another.
