  • Patent number: 4181955
    Abstract: Apparatus for automatically generating photographic pictures, such as 35 mm slides, includes a number of microcomputer terminals at scattered locations, a central computer at a location remote from these terminals and a picture producing device for creating photographic pictures from computer generated data. The microcomputer terminals are each provided with a color display and input keyboards for enabling the user to enter data. The terminals are programmed to generate and display in color a number of standard graphical representations having certain variable characteristics. A particular representation and its characteristics are entered by users through the terminal input as answers to questions presented by the terminal. The terminals are capable of modifying the display of a graphical representation in response to user entries which change the answers to the questions so as to create a final set of answers.
