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.
An apparatus for a photographic camera having a lens carrier and a film carrier which are relatively adjustable to each other for the computational transmission of data regarding the lens and film carriers in regard to a facilitated attainment of optimal camera settings in relation to a motif scene to be photographed, the apparatus comprising means for generating spatial coordinate signals which define spatial positions of image points which have been optically image inverted for points of measurement of a motif scene, the spatial coordination signals capable of being entered into signal input points of an electronic calculator, and capable of being retained in the calculator, signal evaluation devices at the signal output points of the calculator, the calculator having a calculation program according to which the calculator generates electrical output signals based on the input spatial coordinate signals and Scheimpflug's Law, and passes them to the signal evaluation devices, which output signals comprise ideal-position signals corresponding to an ideal setting of one of the film carrier and the lens carrier for minimal unsharpness of the reproduction of the points of measurement, and comprise change-of-position signals corresponding to the resetting of one of the film carrier and the lens carrier required for the introduction of ideal settings.
