Title: Encode noise elimination filter
Inventor: FUJIKAWA WATARU
IPC: H04N5/21
Filed: 1990-11-28
Abstract: PURPOSE:To obtain a satisfactory reproducing image by performing encode noise elimination in accordance with picture quality by controlling the characteristics of a coring means and a high-frequency emphasis means by the picture quality of a decoding image. CONSTITUTION:A picture quality decision means 1 calculates a mean value extending over the whole image with quantization width used in the encoding of an image block, and compares it with a prescribed threshold value, and outputs a comparison result. The coring means 2 inputs a decoded digital image signal, and substitutes a value 0 for a low amplitude component whose absolute value is less than a certrain threshold value Tc out of high-frequency components of spatial frequency. At this time, the value of the threshold value Tc is controlled by the output of the decision means 1. The high-frequency emphasis means 3 performs correction in accordance with the Laplacean value of a remarked picture element and the output of the decision means 1 to compensate resolution lowered by the means 2.

Title: Initial ink filling method for ink jet head
Inventor: MURAI TAEKO
IPC: B41J2/165
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To enhance initial ink filling performance by filling an ink liquid chamber with cleaning liquid and then discharging it before ink liquid chamber is initially filled with ink thereby removing dust and foreign matters in a head. SOLUTION: In an initial ink filling method, water containing a surfactant is passed through a filter to produce a cleaning liquid. Prior to initial filling of ink, a common liquid chamber 3, a liquid resistance section 4 and a pressure liquid chamber 2 in an ink jet head is pressure filled with the cleaning liquid from a supply opening and then the cleaning liquid is discharged from a nozzle. In other words, dust in an ink liquid chamber can be removed by filling it with the cleaning liquid and then discharging the cleaning liquid before the ink liquid chamber is initially filled with ink. The time required for discharging the cleaning liquid can be shortened by pressure filling the ink liquid chamber with the cleaning liquid and applying a drive pulse to a piezoelectric element 11 thereby ejecting the cleaning liquid from the nozzle 1.
