Abstract: PROBLEM TO BE SOLVED: To optimize processing conditions regarding correction of defective sections of pictures. SOLUTION: A picture processor reads a picture recorded on a photographic film with respect to R, G, B, and IR(infrared region) and discriminates whether or not a defective portion is to be corrected by referring to 'presence/absence of execution of defective portion correction' which is one of defect correction parameters set by an operator (170).  When the correction is to be performed, the processor detects the defective portion to be corrected of the picture in accordance with set value of 'defective portion detecting standard' based on IR data (174 and 176), selects a correcting method applied to the defective portion in accordance with the set value of 'correcting method applied to defective portion correction' (182), and corrects the defective portion to be corrected in accordance with the set value of 'degree of defective portion correction' by applying the selected correcting method (184, 186, or 188-192).

Title: Feeding device for printing in automatic wire laying machine
Inventor: EBARA HIROSHI
IPC: H01B13/00
Filed: 1986-08-19
Abstract: PURPOSE:To print letters always correctly by installing two rollers which are formed integrally with a wire laying head and nip an electric wire and connecting a motor for driving a roller with one roller and using the other as idle roller and allowing one roller to be press-attached and separated from the other roller. CONSTITUTION:In printing, a driving roller 14 is press-attached onto an idle roller 19 by an air cylinder 16, and an electric wire 7 is nipped by the both rollers 14 and 19, and the feeding speed of the electric wire 7 is determined by the speed of the roller 14, namely by the speed of a motor 18. The speed is made fairly larger than the wire laying speed which is determined by the transfer of a wire laying head 4. Though the difference form a slackening, said phenomenon exists only in the short time for printing, and when printing is completed, said slackening is absorbed. The driving roller 14 performs also the correcting roller action which removes the bending of the electric wire 7. The motor 18 is connected with the personal computer for a printing machine, and the degree of strain of the printing is always kept constant according to the wire speed, and correct letters are marked onto the electric wire 7. When printing is not executed, the roller 14 is separated from the roller 19.
