TL;DR: In this paper, an image data conversion method for converting the image data signal to the runlength signal through the process for reading once or several times a runlength code from a run length conversion table for a given image signal and a process for adding the pertinent run length code when the same type of code appears continuously.

Abstract: An image data conversion method for converting the image data signal to the runlength signal through the process for reading once or several times a runlength code from a runlength conversion table for a given image data signal and a process for adding the pertinent runlength code when the same type of runlength code appears continuously. A character code/character pattern conversion apparatus which uses said image data conversion method, and provides, moreover, a multiplication device for multiplying character enlarging coefficient and the runlength code and a character interval inserting means which adds a character interval width code to the enlarged runlength code and outputs the input character code after converting it to the enlarged character pattern along with the interval code.

- 11 Dec 1984
TL;DR: In this article, a method for converting an image from a bit map to a run end or run length representation includes the steps of: storing the image as a bitmap representation; accessing for each byte in an image by a look-up table a selected routine, corresponding to such byte, from a number of routines for converting bit strings to run representations, wherein the lookup table accessed is selected in accordance with a color value of a preceding pixel binary bit.

TL;DR: In this paper, the expansion of each point in a stored character pattern is accomplished by a relationship that takes into consideration the points surrounding the point to be expanded, and when a character requires a binary pattern that is not readily susceptible of this type of expansion, the full display size pattern must be stored in memory.
