发明名称 Recording apparatus and method of picture image
摘要 A method of and apparatus for recording picture image wherein by a memory circuit are memorized a plurality of matrix groups each having a plurality of threshold values with a predetermined density distribution arrayed according to a predetermined order, by a circuit is divided a picture image to be recorded into a plurality of picture regions and is obtained picture density data for each of the regions is obtained, by a matrix selecting circuit is selected from the plurality of matrix groups memorized in the memory circuit matrices corresponding to the picture density data detected for each of the regions, and by a comparator is compared each picture element level of electric signals indicating a picture image information with each threshold value of the matrix selected by the matrix selecting means and is generated an output binary signals thereof.
