摘要： An encoding/decoding system to be connected to an external microcomputer, video memory, photoelectric reader or printer comprises an address generator for generating an address to access the video memory word by word, a transition point detector for parallelly processing a video signal word by word to detect a color information transition point address, and execution unit for calculating an address difference from two color information transition point addresses or the color information transition point address based on a difference between two color information transition point addresses, an encoding/decoding table for converting an address difference to a code word and converting a code word to an address difference, and a decoded video signal generator for parallelly reproducing a video signal based on the address difference.

摘要： A plurality of lead electrodes are connected to a strip-like heating resistor in parallel and at regular intervals so as to define a heating resistor section between the adjacent lead electrodes. The heating resistor section is supplied with a current across the lead electrodes connected on both sides thereof. According to this invention, one recording block is constructed of a plurality of such heating resistor sections, and the heating resistor sections are sequentially energized within each recording block. By performing a plurality of such energizing cycles within each recording block, dots corresponding to the respective heating resistor sections are recorded.
