The present invention relates to the image achieved by any conventional method of capture and their subsequent computer processing. The process of the invention presented is based on the simultaneous processing of the input images and their restoration (deconvolution) pixel by pixel by means of a new mathematical method. Furthermore, and in the case of having more than one image of the scene in question, the system is capable of providing superresolution of the input images. It has direct application in digital photographic cameras, digital video cameras, mobile phones, video and photography edition programmes, image analysis programmes for microscopy and astronomy, analysis of medical images, forensic image, image-based security systems, aerial image and in the restoration of works of art, among others.
