PCT No. PCT/CH85/00152 Sec. 371 Date Aug. 8, 1986 Sec. 102(e) Date Aug. 8, 1986 PCT Filed Oct. 9, 1985 PCT Pub. No. WO86/02465 PCT Pub. Date Apr. 24, 1986.The professional camera comprises a plurality of electronic measurement sensors. A first measurement sensor (37, 38) is intended for the angle ( omega ) by which the base (10) of the camera is inclined to the horizontal during focusing. A second measurement sensor (42, 43) is intended for the displacement ( DELTA s) by which the image standard (13, 17) must be displaced along the base of the camera if two objects located different distances from the lens (12) are to be sharply focused. A third measurement sensor is associated with the distance (d) between the image of the two objects perpendicular to the axis of inclination of the base of the camera. The camera furthermore comprises an electronic circuit (30) which processes the output signals of the measurement sensors and at the output (48of which a signal appears which corresponds to the angle ( delta ) by which the image plane (13) must be swung in order sharply to focus both the objects (14, 16) at the same time. The professional camera permits the determination of the angle of swing ( delta ) from the displacement ( DELTA s) of the vertically arranged image plane (13) along the base (10) of the camera independently of the angle of inclination ( omega ) of the base of the camera to the horizontal (11). |
