Abstract

PURPOSE:To obtain accurate distance information even with a camera whose lens barrel is not provided with a distance ring, by calculating the position information of an image pickup means and focus distance information of the image pickup lens, calculating the pickup distance with an object and displaying the result in a video camera moving the image pickup means to apply focusing. CONSTITUTION:A video signal outputted from an image pickup element 2 is supplied also to a focus detection circuit 12 and a high frequency component level in the video signal in response to the position change of the element 2, a driving pulse generator 5 is controlled to drive a motor 4 based on its output and the image pickup element 2 is moved to a focusing position where the high frequency component level is maximized. The information of the focus of the image pickup lens 1 is detected by a focal distance detector 7, the position information at the focal point of the image pickup element 2 is detected by a pulse number detector 6 counting the output of the driving pulse generator 5 respectively, the result is fed to a distance information converter 8, where the distance information with an object is calculated. The distance information is fed to a display circuit 11 and the distance with the object is displayed in a form of numeral or scale is displayed on the screen of an electronic view finder 10.
