Title: Image processing method
Inventor: TAKAOKA NAOKI
IPC: H04N1/409
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To easily obtain an image, without using a special filter, equivalent to an image whose image tone is changed by intention through the use of the special filter. SOLUTION: All highlight points are extracted from an image (refer to figure (A)) to which addition of striation is instructed and an area on which many highlight points are concentrated (an area where many highlight points are in existence adjacent to each other or closely to each other) is extracted as a bright area (an example of extraction of a bright area is shown in mark '.'in figure (B)). Then a parameter to specify the striation added to each bright area is decided based on a characteristic amount such as lightness, size and color of the right area and striation data representing striation added to each bright area are generated.  The generated striation data are synthesized with image data and the resulting image data are used to record an image on a recording material so as to obtain an image with an image tone equal to that of an image photographed by using a special filter such as a cross filter.

Abstract: PURPOSE:To simplify the constitution and to attain the recording and reproducing of a still picture without mechanical or electrical switching by recording two fields of data of still picture in one track of a magnetic disc. CONSTITUTION:In one track 2 or another 5 of the magnetic disc 1, a half track of even-number field 3 and of odd-number field 4 are provided, so that two fields of picture data are recorded in one track 2 or 5.

Title: Ink jet recording system

IPC: B41J2/07
Filed: 1982-06-10
Abstract: PURPOSE:To elevate the print quality free from distortion of the printing by making jet into particles reaching the surface of a print paper simultaneously both from the center nozzle and other nozzles among those vertically arranged in plurality. CONSTITUTION:The reaching range of ink particles from nozzles of the print head 3 is different by DELTAS between the central nozzle Pn/2 and (k)th nozzle Pk because a paper 7 runs along the circular surface of the platen and distortion is caused in the printing according to the moving speed of the print head 3. In this system, a speed distribution V1-Vn/2-Vn from the nozzles is preset for the drive section and ink drops are jetted from the nozzles of the print head 3 according to the set speed. This makes the reading time of the ink equal between the nozzles eliminating distortion in the printing. The same effect can be obtained by interposing a delay circuit between the control section and the drive section to delay the time in inverse proportion to DELTAS.

IPC: H02M3/155
Filed: 1989-04-18
Abstract: PURPOSE:To reduce the size of a transistor(Tr) by employing the output of a first charge pump voltage converter (CP) as the source voltage for a second CP and feeding the higher one of the input or output voltage of the second CP to the input terminal of the first CP. CONSTITUTION:Output terminal 14 of a CP 1 is connected with the input terminal of a voltage detector (VS) 15. Immediately after application of voltage onto an input terminal 3, voltage at the output terminal 14 is lower than the input voltage and thereby the output of the VS 15 goes to low level thus turning a Tr 17 ON while turning a Tr 18 OFF and applying input voltage onto the input terminal 19 of a CP 2. Voltage at the output terminal 14 of the CP 1 increases with time and the output of the VS 15 is inverted to high level thus turning the Tr 17 OFF while turning the Tr 18 ON, and applying output voltage of the CP 1 onto the input terminal 19 of the CP 2 while a voltage several times as high as the output voltage of the CP 1 onto the output terminal of the CP 2. By such arrangement, ON resistance of a Tr can be lowered.
