Title: Receiving circuit of spread spectrum communication
Inventor: OONISHI KENICHI
IPC: H04B1/709
Filed: 1983-07-05
Abstract: PURPOSE:To restore normally information data by preventing the generation of an erroneous sample signal due to mixing of a noise or the use of a PN code having a side lobe even if the noise is mixed in the side lobe of a correlation output or the PN code having a side lobe is used. CONSTITUTION:When information data is ''0110'', contents of the first shift register 8 are outputted to the first frame of a selected output A because preceding data is ''0'', and contents of the second shift register 9 are outputted to the second frame because preceding data is ''1'', and contents of the second shift register 9 are outputted to the third frame because preceding data is ''1''. Similarly, contents of the third shift register 10 and the fourth shift register 11 are outputted to the first frame and the second frame and the third frame in a selected output B respectively. Thus, in one of output signals phi1(t) and phi2(t) of comparators 6 and 7 where selected outputs A and B are subtracted from a correlation output phi(t), the side lobe is cancelled to be zero in one frame. Consequently, a sample signal E which is logical ''1'' in accordance with the peak point of the correlation output phi(t) is obtained.

Title: Dot threshold setting method and binary data generation device
Inventor: INOUE YOSHIAKI
IPC: G06T3/00
Filed: 1995-05-23
Abstract: PURPOSE: To prevent occurrence of the moire fringes by deciding alternately the threshold value which are allocated to the pixels included in dot cells of the shadow point centers. CONSTITUTION: A supercell is divided into dot cells Hh of the highlight point centers and also into the dot cells Hs of the shadow point centers. The threshold value 0, 1, 2, 3... which are allocated to the pixels included in cells Hh of the highlight point centers and the threshold value N, N-1, N-2, N-3... which are allocated to the pixels included in cells Hs of the shadow point centers are alternately decided (in order of 0→N→1→N-1→...→3→N-3). As a result, the number of blackened pixels included in the cells Hh is equal to the number of white-on-black pixels included in the cells Hs in terms of every dot cell included in the supercell S when an original image has high density. Thus it is possible to prevent the moire fringes that are caused by the periodical changes of the number of blackened pixels included in the dot cells.
