Abstract
An image generation method and an image generation apparatus can execute conversion from edge addresses into dot patterns at a high speed and a low cost. A comparator compares predetermined upper-digit bits of input edge-address information indicating the position of a word of a dot pattern to be output with the value of a word counter for counting the number of words of dot patterns which have been output, and determines if an edge position indicated by the input edge-address information is present within the word currently being processed. A decoder detects the edge position within the word based on predetermined lower-digit bits of the input edge-address information. The detected edge position within the word is held within a flip-flop circuit. A pattern generator generates the dot pattern of one word from edge positions within the word held by the flip-flop circuit in accordance with the logic of a dot at an end of the word of the dot pattern which has been output immediately before the word being processed.
