A collective output system includes an information processing device and a plurality of terminal devices. The information processing device holds content containing multiple elements in association with time information, generates a map that associates each piece of position information with each of the elements, receives output position information from a terminal device, acquires, on the basis of the map, an element associated with the position information corresponding to the output position information, acquires the time information associated with the content, and transmits the element and the time information to the terminal. Each of the terminal devices acquires the output position information, transmits the output position information to the information processing device, receives the element and the time information that are transmitted from the information processing device according to the transmitted output position information, and outputs the element at the timing indicated by the time information.

A method for generating character pattern data includes steps of providing contour information of a character having m.sub.1 .times.m.sub.2 coordinate values in a coordinate space; and making and outputting gradated character pattern data of l.sub.1 .times.l.sub.2 picture elements for an output device having n gradiations per picture element (where m.sub.1, m.sub.2, l.sub.1, l.sub.2, and n are positive integers). In an image making method, picture subelements provided by dividing an original picture element are set as a scanning unit and an image is made by scanning conversion using the picture element having a gradation to perform a coloring operation with respect to the interior of a two-dimensional contour line. The image making method includes representing and processing a numeric value such as a coordinate value of a line segment constituting the contour line as a virtual real number having a decimal point in a word; providing positions for starting and completing the coloring operation easily by the representation of the virtual real number; and providing a brightness of a displayed picture element at a high speed by only adding an integer value to a region on one line in an output device.
