Abstract: An improved system using an auto focus camera for capturing images of interested objects in the same image resolution over a large range of object distances. The system provides a camera including a zoom lens system responsive to a zoom signal Z and an auto focus lens system, comprising an imaging system operative to image one or more objects at varying object distances, an auto focus controller operative to adjust the auto focus lens system based on a characteristic of the image so as to maintain the object in focus and to output an auto focus status signal, and an auto zoom controller operative to adjust Z by an amount obtained by applying a function to the auto focus status signal, as it varies with the object distance, to maintain an approximately uniform image resolution.
