Abstract: A video camera for minimally invasive surgery is an important tool and should be smaller, lighter and provide high quality images but these cameras are very expensive, so use in simulators is to raise costs. The objective of this work is to implement image processing techniques and a system of magnifying lenses to improve the quality and realism obtained from commercial use webcams and replace the high-resolution camera on minimally invasive surgery simulators. An application of image processing is shown for a closed environment aimed at learning medical operations of minimally invasive surgery.
“SolidWorks 2014 x64 Edition” with the camera and arthroscopy measures. Although the image is sharp, very small, so it seeks to expand by physical means, for this purpose a magnifying glass was used, the best option was 10x lens.

The quality of the images obtained by a digital camera is given by the CCD chip (charge-coupled device), which are state image sensors. The amount of light is measured in lux, usually they need 6-10 lux to have the minimum necessary amount of light for a quality picture, but there are models they only need 3 lux SIS (suspended image system) [3]. The lighting system is independent and is provided by an array of LEDs with adjustable intensity. The target is placed at least 2 cm from the camera, this is considered by the distance that MIS are performed. The part of the optics focuses on the use of lenses to concentrate light beams. Using different lenses with Macro function and 10x magnification which combine to increase the image.

INTRODUCTION
The equipment needed to create a clinical simulation center is high technology, and the purchase is an expensive proposition for most hospitals and medical training centers. Hospitals, universities and training centers that do not have enough funds for normal administration may be impossible to invest large sums of money in a clinical simulation center [1]. Learning for minimally invasive surgery (MIS) is a fundamental aspect in its development and introduction in daily practice. For its realization several psychomotor skills quite different from open surgery are necessary. Besides the time spent on the learning curve it is still very long [2]. One of the essential tools is the high-end camera, this has a high cost depends on the number of sensors containing. The project is to design and build a system that can replace the high-definition camera. This proposal has two parts: a physical part that it comprising a focus control and a lens arrangement to amplify the image, and a virtual part of processing the image to prevent image distortion, as well as get color reproduction close to the re
