PROBLEM TO BE SOLVED: To realize an appropriate focus correction by detecting temperature to obtain accurate information on the change of the back focus of an image pickup lens. SOLUTION: In a video camera, a temperature detecting element 25 is arranged on a flexible wiring board 24 to which image pickup elements 21 to 23 such as a CCD, etc., are electrically connected and the information on the change of the back focus of a movable lens group consisting of three lenses 10a, 10b and 10c is obtained by using a detection output signal from the detecting element 25. Based on the information on the change of the back focus, the focus position of the movable lens group is corrected. |
