Title: Image output method, inspection method, image output device and inspection device
Inventor: KO HIROTETSU
IPC: G06T1/00
Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To suppress copying through the appearance of an imbedded water mark image in the case of an image output by a conventional printer regardless of an invisible state of the watermark by superimposing an original image and a watermark image by different image reproduction methods in the case of image output. SOLUTION: External original image data are given to a color converter 10, where the color of the data are converted. For example, RGB original image data are converted into CMY original image data. Then the original image data whose color is converted is given to a pseudo gradation processing unit 30, where the data receive pseudo medium tone processing for area modulation. The original image data after the color conversion (for intensity modulation) C, M, Y and the original image data (for area modulation) C', M', Y' receiving pseudo medium tone processing are both given to a weight averaging device 40. The weight averaging device 40 receives watermark image data whose high frequency component (steep change) is suppressed by a low pass filter 20 to apply weight control to the data so as to obtain image data where intensity modulation and area modulation are intermingled.

Filed: 1991-10-21
Abstract: PURPOSE:To perform the accurate measurement of sample gas by providing a means, which makes carrier gas flow periodically and measures the value of the voltage signal of a base line, and providing a means and the like for measuring each component with stored average value as a reference. CONSTITUTION:When each component of sample gas 1 is detected as a voltage signal V1 with a TCD sensor 2, the signal V1 is amplified with an amplifier 4 and outputted to one terminal of an adding circuit 5. In the circuit 5, the signal V1 is added to a voltage signal V2 for canceling a base-line voltage VB, which is inputted through the other terminal, and the voltage VB is removed. A voltage V3 is obtained and sent to one terminal of an amplifier circuit 6. In the circuit 6, the signal V3 is amplified in response to the gain value inputted through the other terminal, and a voltage signal V4 is sent out to a V/F converter 7. The converter 7 generates the frequency signal corresponding to the value of the signal V4 and sends out the signal into a counter 8. A CPU 9 detects the component in the gas 1 when the counted value, which is read at a specified period, is a specified value or higher.

Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To eliminate the generation of pseudo pulses and to prevent malfunctions by turning the wiring pattern of a printed board for performing connection from a driver IC to plural receivers ICs to a loop shape. SOLUTION: The output of the driver IC is connected to one end of a dumping resistor R100 and the dumping resistor R100 is connected to the wiring pattern P1. The input terminals 111, 121, 131 and 141-271 of the respective receiver ICs 110, 120, 130 and 140-270 are connected on the wiring pattern P1. Even in this multi-connection device in the case of unidirectional transmission, the impedance of all the receiver ICs 110-270 and the impedance of the wiring pattern P1 on the printed board can not be matched. Thus, when the driver IC 100 originates digital signals, reflected waves from the receiver ICs 110-260 between the driver IC 100 and the receiver 270 at a farthest end are synthesized and the waveforms of the respective input terminals 111-271 are turned to stepwise waveforms.
