Abstract:
Provided are a capsule-type image photographing apparatus and endoscopy using the same. The apparatus includes a shell unit having a globular shape and a main body unit capable of freely rotating in the shell unit. The main body unit includes an image photographing system, a wireless transmitter, a battery, a counterweight for determining the center of gravity of the main body unit, and an encapsulant for fixing the image photographing system, the wireless transmitter, the battery, and the counterweight. The apparatus may be a long-distance capsule-type image photographing apparatus or a short-distance capsule-type image photographing apparatus depending on the position of the counterweight. By use of the long- and short-distance capsule-type image photographing apparatuses, the interior of the tested person's body can be effectively photographed.

Abstract:
There is provided a method for controlling a stepping motor by employing a micro-step mode at deceleration or acceleration of the stepping motor, which moves an optical pickup head in a full step mode or a half step mode, to minimize lens vibration of the optical pickup head. The method includes setting an initial step of the stepping motor, applying a micro-step mode to the stepping motor at the set initial step to move the optical pickup head, and after the initial step, applying a full step mode or a half step mode to the stepping motor to accelerate the optical pickup head by a desired speed. Also, the method includes setting a late step of the stepping motor, applying a full step mode or a half step mode to the stepping motor to decelerate the optical pickup head by a desired speed, and applying a micro-step mode to the stepping motor at the set late step to move the optical pickup head.
