Patent JP-H0358675-A (JP)
Title: Digital comparator
Inventor: TAKADA MIGAKU
IPC: H04N19/423
Filed: 1989-07-27
Abstract: PURPOSE:To eliminate shot noise near the border between a moving picture and a still picture and single shot noise by providing an AND circuit receiving an output of a comparator and a signal from a clear terminal and a comparison value setting circuit setting the comparison value based on the past value of an output logical value of the AND circuit. CONSTITUTION:When a moving detection signal from an input terminal 1 is larger than an output logic value of a comparison setting circuit 6, a comparator 3 outputs logical 0 and when not, the comparator 3 outputs logical 1. An AND circuit 5 is inserted between the comparator 3 and the circuit 6, a logical 0 being an initial value is inputted from a clear input terminal 4, the initial value is inputted to the comparison value setting circuit 6 and after the value of the loop circuit is ascertained, the level of the clear terminal 4 is set to logical 1 so as to input an output signal of the comparator 3 to the circuit 6. Thus, after the moving detection signal is once discriminated to be a moving picture, a movement detection signal inputted thereafter is hardly discriminated to be a still picture, and when the signal is once discriminated to be a still picture, the signal inputted thereafter is hardly discriminated to be a moving picture, then single shot noise is eliminated and shot noise near the border between the moving picture and the still picture is eliminated.

Filed: 1991-07-11
Abstract: PURPOSE:To simplify the structure of a printer, to prevent a complicated circuit structure, delay in processing operations and erroneous operation controlled by a program by preparing plurality of smoothing means and selecting one of them according to pixle arrangement state. CONSTITUTION:A bit map (7X7) formed of 3 lines in front and in the rear and 3 bits on the right and the left of a reference pixel is stored and arranged, while being renewed successively for its contents by data transferred from an SRAM 105, in a seven-line shift register 113, and thereby smoothing by smoothing circuit becomes possible, utilizing the bit map. In the case where video data is a second smoothing video data which is shifted to the right and the left, the data exceeding 12 bits are stored in shift registers 118 and 119. Therefore, output in appropriate clock units becomes impossible even if the data is outputted without change. Then, the output from the shift registers 118 and 119 are taken alternately based on video clocks, taking the logical sum,,and thereby continuous video data can be outputted serially.

Title: Video signal conversion system/apparatus
Inventor: HATANO YOSHIKO
IPC: H04N19/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To reduce redundancy in a time direction and to reduce a frame frequency by thinning fields which are repeated and outputting the video signal of two frames whenever the video signal of five fields is inputted. SOLUTION: The input video signal is delayed by one frame in a frame memory 1. An evaluation unit 2 obtains a difference signal between the input video signal and a delay signal and evaluates the size of the difference signal at ever field. The evaluation value is for judging the repetition of the field. When the evaluation value is more than a constant th (th>=0), the same picture is prevented from being repeated. When it is smaller than th, repetition is judged to exist. The evaluation value is inputted to a judgment unit 4. The judgment unit 4 decides the field to be thinned at every five field by using the evaluation value. The video signal from the memory 1 is stored in the memory 3 for more than five fields. The memory 3 outputs two frames whenever the video signal is inputted for five fields in accordance with the judged result of the judgment unit 4.

Title: Voltage-level detector arrangement
Inventor: GIYUNTAA JIIGUBERUGAA
IPC: G01R19/165
Filed: 1989-07-31
Abstract: PURPOSE: To obtain a voltage level detecting circuit which operates at a low power supply voltage by changing the continuity of a semiconductor device when the absolute value of the voltage difference between an input terminal and a second power supply voltage terminal exceeds the absolute value of the voltage difference between first and second power supply voltages. CONSTITUTION: In a first voltage range of 0-1.5V, transistors (Trs) Q2 and Q5 are cut off and no current flows to output terminals C1 and C3 . A Tr Q4 makes all currents of current mirrors Q10 and Q11 to flow and the currents appear at a terminal C2 through current mirrors Q8 and Q9 . Within another voltage range of 2.1-2.9V, the Trs Q2 and Q5 are cut off and no current flows to the terminals C1 and C3 . In this case no current flows to the terminal C2 also because all emitter direct current of differential amplifiers Q3 and Q4 flow through a transistor Q3 . When the input voltage is 3.5-5V, all currents of the amplifiers Q3 and Q4 flow through the Tr Q3 and the Tr Q2 is maintained at a zero current.  At the terminal C3 , the Tr Q5 is left cut off and the Tr Q2 is turned off, because the base potential of the Tr Q2 becomes lower than that of the Tr Q1 , and a current flows to the terminal C1 . Therefore, the voltage level can be detected.
