The method comprises steps of; receiving a pixel image, generating at least two histograms of the received image using at least two different frequency components, finding widths of acquired histograms and storing them as a focus measure, finding difference between last received frame's highest frequency component histogram width and at least one previously received frame's histogram width corresponding to the same component, determine whether there is a meaningful difference, and determine the focus direction signal by using the difference. The system comprises; an image sensor to acquire an electronic pixel image; an image processing unit configured to receive an image and implement the method using this image and output a focus direction signal found by the method; and a memory unit configured to store image histogram widths."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for focusing an electronic imaging system","description":"The present invention relates to the field of image processing and methodologies to passively focus an image automatically, using the electronic sensor signal.
