DATA MEMORY CIRCUIT OF PICTURE MEASURING

摘要

PURPOSE:To secure both a label data storage function and a run length compression storage function with the improvement of reliability and the reduction of the cost in a simple constitution, by using plural input buffers and a comparator. CONSTITUTION:Memories 11 and 12 store the run length compression data or the label data, and the 1st input buffer 13 receives the label input data. While the 2nd input buffer 17 receives the binary picture data (run length compression data) and the output of a coordinate counter. The comparator 18 compares the output of the coordinate counter with data given from memories 11 and 12. Here an X counter is used to the coordinate counter. Thus a lable data memory circuit contains two buffers 13 and 17 to receive the run length compression data and the output of the coordinate counter as well as the comparator 18. This secures both the label data storage function and the run length compression function in the simple constitution together with improvement of reliability and the reduction of the cost.
