Title: Character area discriminating method and character recognizing method
Inventor: TAKAKURA SHUICHI
IPC: G06K9/20
Filed: 1988-09-05
Abstract: PURPOSE:To segment a character area from a character picture of large noise without error by discriminating the area, where the sum total value of histogram values of picture elements is maximum, out of areas, each of which consists of continuous picture elements which include a reference picture element and whose number corresponds to the size of a character, as the character area. CONSTITUTION:The character picture is divided to picture elements to convert it to a binary picture, and the picture element histogram of the binary picture is generated, and one of picture elements in the binary picture included in a reference area is defined as the reference picture element of the character area. The area where the sum total value of histogram values of picture elements is maximum out of areas consisting of continuous picture elements which include the reference picture element and whose number corresponds to the size of a character is discriminated as the character area. Thus, an area deviated from the true character area is prevented from being discriminated as the character area, and discrimination of the character area is not affected though the noise having a histogram value larger than that of the character area exists near the character area.

Title: Method of testing semiconductor wafer and semiconductor integrated circuit
Inventor: OMORI SOHEI
IPC: G11C29/56
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To realize high integration and low power consumption of a semiconductor integrated circuit by cutting wiring means for connecting the semiconductor integrated circuit and a diagnostic circuit when semiconductor integrated circuits are obtained by a dicing process. SOLUTION: After circuit function test of each IC chip on a semiconductor wafer, the semiconductor wafer is diced along scribing lines to thereby obtain respective semiconductor integrated circuits. A diagnostic circuit is substantially destructed in the dicing process and is separated from the semiconductor integrated circuit. A lead connecting the semiconductor integrated circuit and the diagnostic circuit is cut by the dicing operation. In IC chips obtained by the dicing operation, since the diagnostic circuit is separated, substantial high integration and low power consumption can be realized. Since no gate circuit which is to be cut from an internal logic circuit exists in the lead connecting the diagnostic circuit, the high speed can be realized in an inherent operation.
