Patent JP-H1141464-A (JP)
Title: Image processor and image processing method
Inventor: SAKAMOTO SHIGERU
IPC: G03G15/04
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To improve gradations at the low density image input time without reducing the number of total gray levels in a dither matrix by providing a storage means for storing the threshold level of a low gray level in the matrix as a specified type. SOLUTION: A threshold memory 3 for storing the threshold level defined by the dither matrix stores the threshold level of the low gray level in the matrix as a type M (0<=M<m). In the case of three threshold levels corresponding to an address to take the lowest gray level among 3×3, for example, the totally overlapped equal value is stored in advance. The input image is compared with an (m) threshold level image in the matrix of m×n (n>=3) and based on binary data generated corresponding to the compared result, the input image is processed while referring to and comparing with the threshold memory 3 and by decreasing the number of gray levels in the image pixel of the low gray level from (m) to M, the pixel can be prevented from being isolated with the low density so that the gradations can be improved without reducing the number of total gray levels.

Title: Read only memory of amorphous silicon based nand structure and manufacturing method therefor
Inventor: ON EIMO
IPC: H01L27/112
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a ROM device in which a source/drain region is insulated from a substrate below the source/drain region by the SOI structure and no leak current flows therebetween. SOLUTION: A source/drain region 50 is insulated from a semiconductor substrate 30 below the source/drain region 50 by an SOI structure, to thereby prevent leak current from bowing therebetween. Failures caused by a diode junction between the semiconductor substrate 30 and the source/drain region 50 is prevented, to thereby improve the operating voltage. The source/drain region 50 of a MOSFET memory cell is formed out of intrinsic amorphous silicon instead of heavily-doped polysilicon. The ROM device manufacturing method is thus quite simplified.
