Title: Noise elimination method for copied picture
Inventor: UEDA HIROO
IPC: H04N1/409
Filed: 1978-11-13
Abstract: PURPOSE: To eliminate the ground dirt and thus to obtain a high-quality picture by dividing the original picture according to the density of the picture element into three sections: the picture part; the non-picture part and the obscure part each, and regarding the obscure part continuing in the fixed length as the non-picture part.  
     CONSTITUTION: The upper and lower threshold levels T 1  and T 2  are decided by arithmetic circuit 100, and output arithmetic circuit 200 delivers the input signals in the form of 0, 1, Sn/(T 2 -T 1 ) according to levels T 1  and T 2 . At the same time, count-up signal CNU is delivered to counter 400 when the output is Sn/(T 2 -T 1 ) and then count reset signal CRS is delivered when the output features 0 or 1. Temporary memory unit 300 memorizes the picture element of the number equivalent to the run-length which is used as the decision standard when the correction is given to the obscure part. Accordingly, in case the obscure part continues more than 10 picture elements to be regarded as the non-picture part, counter 400 delivers reset signal RST to unit 300 to clear the memory contents. Thus the obscure part regarded as the non-picture part is corrected as the ground, as a result obtaining an extremely clear picture.
