Science Innovation. Vol. 3, No. 1, 2015, pp. 1-17. doi: 10.11648/j.si.20150301.11 Abstract: The work presents the evolution of a technical idea concerning the automatic image focusing in photo cameras, TV cameras and camcorder-type recording cameras. The work aims to present both the evolution of the technical solutions, and a Romanian priority concerning the automatic focusing reached by the technologies of the optical and electronic industries of image taking only 15 years after having been patented in Romania the most utilized principles, namely the dynamic analysis of image contrast, a principle used in commercialized cameras after the years ’80. Keywords: Autofocus, Patents, History, Contrast Image, Phase Contrast, Photocamera 1. Introduction In order to obtain sharp images in the photo or video together such that, irrespective of the distance, the cameras, an operation called adjustment for definition or accommodation is performed automatically, through
