摘要： PROBLEM TO BE SOLVED: To realize an image display device and a picture image, having no flicker and an improved image quality, capable of calculating an optimum sampling timing of an image signal even in the case of a slowly-rising image signal, and an image display method. SOLUTION: The point of time t1 and the point of time t2 when a voltage level of one pixel signal waveform reaches 20% and 80% respectively are detected, and t1 is subtracted from t2, and the subtraction result is multiplied by a coefficient K, to thereby estimate a rising period t0-80 of the voltage level of an image signal from 0% to 80%. Then, the period t0-80 and a jitter portion toff of a sampling clock are subtracted from a known one pixel period tdot, to thereby calculate a period from the point of time when the voltage level of the image signal reaches 80% to the optimum sampling timing topt. Then, the image signal is sampled based on the calculated period.

摘要： PROBLEM TO BE SOLVED: To solve the problem, in which cost is increased due to the addition of an inlay area specification circuit in the case of increasing the luminance of an area displayed by inlaying a television image such as a natural image into a computer image such as characters and graphics. SOLUTION: A key signal (blanking signal) generated from an image signal generation means included in an image display apparatus is utilized as a signal for specifying an inlay position. Consequently the luminance level of an inlaid image can be controlled by almost the same circuit scale and cost as that of a conventional image display apparatus. Television images such as natural images can be brightly and finely displayed and computer images such as characters and graphics can be displayed at low luminance so as to be easily read.

摘要： PROBLEM TO BE SOLVED: To transmit a plurality of signals or data through one system of transmission line. SOLUTION: At a transmission block, component video signals of a luminance signal Y and color difference signals Pb and Pr are subjected to FM modulation and filtered by a filter circuit in order to extract only required frequency components. The extract frequency components are added by an adder and collected to one system and an infrared LED is driven by a signal of that system to transmit an infrared signal. At a receiving block, signals received by a pin photodiode(PD) are amplified and filtered by means of filters corresponding to the luminance signal Y and the color difference signals Pb and Pr in order to extract only required frequency components. The extracted signals are inputted to an FM demodulator so that the component video signals of the luminance signal Y and color difference signals Pb and Pr are reproduced.

摘要： PROBLEM TO BE SOLVED: To reproduce a video without subdual for a natural image such as TV video signals by preventing chroma from decreasing at low brightness levels in a liquid crystal display device. SOLUTION: In an image display device provided with an APL detection means 5 to detect an average video level (APL) of input video signals, AMP circuits 2, 3 to vary a gain of the input video signals, and a hue detection means 90 to detect a specific hue signal, the AMP 2, 3 control the gain of the video signal for the hue detected by the hue detection means 90 according to the average reflection level of the input video signals detected by the APL detection means 5, to change the chroma to desired hue of the video signal, and thereby it becomes possible to attain a shining video display image even at low brightness levels, and realize a well-modulated video display equal to a CRT image.

摘要： PROBLEM TO BE SOLVED: To display a dynamic image by a bright and powerful image plane, even when a color temperature setting of a display reference white color is changed, and to enable selection between a display in which a white balance of a display element is given priority and a display in which a luminance is given priority. SOLUTION: An analog picture signal inputted from a signal source 8 is digitally converted by an A/D converter 1, and inputted into a lookup table 2 by which a white balance is given priority in a low-luminance region and a luminance is given priority in a high-luminance region. A reference top voltage of the A/D converter 1 is changed over corresponding to the data from an adjusting button 7, to thereby change output signal data, and the maximum value is controlled so that it will fall in the data range where a white balance is given priority by the lookup table 2, and consequently, a display having a low luminance but an excellent white balance can be obtained. In case that the maximum value is controlled so that it will fall in the data range where a luminance is given priority, a display having a disordered white balance but a high luminance can be obtained.

摘要： PROBLEM TO BE SOLVED: To make luminance levels of respective cores constant by fetching reference voltage signal in video signal and performing feedback control so that these reference signal levels are matched with each other in respective cores thereby absorbing variation of ABL control characteristics as a system. SOLUTION: Reference voltage inserting circuits 3a-3d insert reference voltages in overscanning periods of video signal to be inputted to contrast and/or luminance control circuits 11. A comparator circuit 2 compares reference voltages inserted in the video signals of respective cores to output the compared results. An comparator circuit for ABL 6 compares ABL control information of the respective cores and selects the core showing the maximum beam current value to output the ABL information of the core indicating the maximum beam current value and also controls switches 50 of respective cores. That is, the continuity of luminances at boundaries of respective cores is obtained by suppressing luminance variations due to the variations of the ABL control characteristics of respective cores by the feedback control of the comparator circuit 2.

摘要： PROBLEM TO BE SOLVED: To simultaneously display a computer image such as characters and graphics and a television image at a luminance proper to the respective images by inserting the television image to the computer image. SOLUTION: A program of a CPU circuit 4 and image data A are stored in a ROM circuit 5 and the CPU circuit 4 runs on the program. The CPU circuit 4 reads the image data A from the ROM circuit 5 and gives the data A to an image synthesis means 3 as an image signal A. Furthermore, an image signal B is received from an input terminal 7 by an external input means 6 and fed to an image synthesis means 3, in which the signal B is inserted to an insert position designated by the CPU circuit 4 receiving the image signal A. A synthesis image signal Video 1 from the image synthesis means 3 is fed to a specific area luminance conversion means 2, in which a prescribed luminance level is set independently to the image signal A and the image signal B in a timing of a timing signal fed from the CPU circuit 4 via a signal bus 8 and they are displayed simultaneously on an image display means 1.
