In order to generate an image, modelling data representing image features of the image are stored in a data base, and first characteristics, such as colors, are stored in another data base. An analyzer unit is then able to assign the first characteristics to the image features in an objective way. Subjective properties, e.g. `darker`, `lighter`, are also defined over a range for the image features and a user interface permits a user to select an appropriate value of the subjective property within the range, thereby to generate a second characteristic on the basis of rules relating to the subjective properties stored in a data base. An interpreter unit then modifies the first characteristic on the basis of the second characteristic before the selected image features are rendered into an image by a rendering unit for display by a display unit. There is also disclosed an arrangement for associating characteristics of image feature on the basis of an ordered relationship of other characteristics of the image features, preferably making use of a reference image to derive the characteristics to be associated.

A biological image formation aiding system and a biological image forming method are provided in which three-dimensional data corresponding to a standard shape of a biological article, standard motion thereof, and a standard material feeling of an outer surface of the biological article are prepared, and a realistic three-dimensional synthesized image of an entire biological article with individuality can be formed simply. The system includes a shape data storage for storing data corresponding to a three-dimensional shape of a biological image; a motion data storage for storing data corresponding to three-dimensional motion of the biological image, a material feeling data storage for storing data corresponding to a three-dimensional material feeling of an outer surface of the biological image; editing/processing units capable of modifying at least one of the data corresponding to the three-dimensional shape of the biological image, the three-dimensional data corresponding to the motion of the biological image, and the data corresponding to the three-dimensional material feeling of the outer surface of the biological image in accordance with a producer's intent; and an output unit responsive to the outputs of the editing/processing unit for synthesizing the data corresponding to the three-dimensional biological image, the data corresponding to the three-dimensional motion of the biological image, and the data corresponding to the three-dimensional material feeling of the outer surface of the biological image after modification with each other to provide synthesized three-dimensional data for a biological image to be produced.

A three-dimensional shape of an object is recognized by developing enveloping surfaces of the object by a cone-silhouetting method, wherein the object is picked up by a binocular three-dimensional vision method by making use of geometrical restraint conditions derived by the cone-silhouetting method. The binocular parallax is increased to thereby ensure the recognition of the three-dimensional shape with improved accuracy. Local concave portions which can not be recognized by the cone-silhouetting method by itself are recognized with higher accuracy.

Various machines and apparatus equipped in an unattendet remote controlled station are associated with contact means through which the remote supervisory control for the operation of these machines and apparatus is carried out to a master station. Contact information provided by the individual contact means is assigned with an indication input type determined by a setting circuit provided for each of the indication input types. The contact information assigned any one of indication input types is stored in a memory circuit having a predetermined memory and holding function which is provided for each of the indication input types. Outputs from the memory circuits are ORed and thereafter converted into a predetermined transmission format, which is transmitted to the master station, thus completing an indication input signal processing. A predetermined number of the contact information is ganged into groups and all of the above-mentioned processes are carried out by processing the groups on a time division basis.
