ABSTRACT:
An apparatus permits, with the aid of an electronic calculator, the calculation of the spatial coordinates of object points of a motif scene to be photographed, and does so based upon the image points optically image inverted for the object points. The calculator is programmed so that, in accordance with Scheimpflug's Law, it generates output signals which correspond to an ideal setting of the film carrier and/or the lens carrier of the camera. By means of electro-optical and/or acoustical signal emitters, the ideal setting of the image and/or lens carriers, or the resetting required for the introduction of the ideal setting, are indicated to the photographer. For this purpose, the mechanical reset mechanisms for the film carrier and the lens carrier are connected to the actual-position signal emitters, which transmit actual-position signals to the calculator. The mechanical reset mechanisms can also be coupled to drive motors, which are controllable by the output signals of the calculator, and in each case automatically introduce the ideal-setting of the film and/or lens carrier ascertained by the calculator.
