Abstract	The correction of images with geometric distortion, in cameras with short-focal length lenses, can be achieved by integrating the solution into the camera's electronic hardware. By analyzing the distortion problem, the calibration parameters for a given camera are obtained to correct the image distortion. Every pixel from the original image is weighted and used to modify several pixels of influence in the output image. The weights are computed by bilinear interpolation. The final design is generic and configurable to different values of zoom and focus. It has been oriented to an FPGA, being possible the correction of the image distortion in real-time, and providing an undistorted digital video stream
