摘要： A video signal processing circuit that uses a prescribed clock signal to process a digitized composite video signal. A clock generating means (2) generates the prescribed clock signal; a burst phase detecting means (3) detects color subcarrier phase information (p) in each line of the composite video signal; a phase difference calculation means (4) finds the phase difference between phase information (p) from the burst phase detecting means and a prescribed reference phase; a sampling phase conversion means (8) corrects the sampling phase of the composite video signal according to phase corrections (Δb, Δt) obtained from the phase difference calculation means (4); a Y/C separation means (9) separates the luminance and chrominance signals from the composite video signal output from the sampling phase conversion means (8). Excellent two- or three-dimensional Y/C separation can be obtained regardless of the television broadcast system, even from a non-standard signal.

摘要： A coding circuit codes present image data of a pixel which is received as raster data and a delay circuit stores a coded image data for one frame period and outputs one-frame preceding image data of the pixel in accordance with an input of the coded image data. First and second decoder circuits decode coded image data and one-frame preceding coded image data, respectively, a variation-amount calculation circuit calculates variation-amount data of both decoded image date, and an one-frame preceding image reproduction circuit reproduces one-frame preceding reproduced image data. An image date correction circuit generates corrected present image data on the basis of the present image data and the one-frame preceding reproduced image data.

摘要： An image pick-up apparatus, wherein a light emitting device sequentially emits a plurality of colors of light to a subject, a mono-color image pick-up element photo-electrically converts light reflected by or transmitted through the subject into color-field sequential signals, a memory stores the color-field sequential signals separately in connection with respective colors, and a convertor sequentially or simultaneously reads out the color-field sequential signals stored in connection with the respective colors in the memory and converts them into desired video signals of various color spaces. A disc shaped light shield device with a slit intermittently interrupts light from the light emitting device.

摘要： In a color image display system formed of a monochromatic CRT or like image display device (102) having a screen (103) for display of images and a rotary filter (106) comprising color filter sections (106R, 106G and 106B) of a plurality of colors; image signals are read from memories (130R, 130G, 130B) at a rate higher than they are written in the memories, so as to reduce flickers. The problem of passing of the reading address over the writing address is solved by reading the image signal of prominent color taking a period in which the passing over occurs. High frequency components of other color image signals are extracted and added to the image signal of each color to thereby enhance the definition of the picture.

摘要： A color image display system includes a monochromatic CRT or similar image display device which includes a screen for display of images and a rotary filter having filter sections of a plurality of colors. The system further includes memories for storing color image signals corresponding to each of the colors. A control circuit reads the color image signals from the memories at a higher rate than the color image signals are written into the memories to reduce image flickering. The reading operation, however, passes over the writing operation. Discontinuities caused by this passing over are reduced by reading a color image signal corresponding to a less prominent color during the passing over. Discontinuities are avoided by providing an additional memory in the system and alternately reading and writing between one of the first set of memories and the additional memory. The system also adds to each color image signal read from a memory the extracted high frequency components from the other color image signals to enhance picture definition.

摘要： A display device is provided that controls, considering affection due to a watcher's age and his viewing distance as human-visual characteristics, a display-screen brightness level at which the watcher does not feel glare. The display-screen brightness is most suitably set by simple calculation using relationships among watcher's ages, display sizes, glare levels, and screen-illuminance levels, etc. obtained by a subjective-assessment experiment.

摘要： In order to reduce the total capacity of a ROM used for adjustment of the black level and the white level of a digitized luminance signal for a television receiver, for example, a comparator compares the input luminance signal with a predetermined threshold value, a NOT gate inverts the input luminance signal, a first switching unit selects the input luminance signal or the output of the NOT gate, a ROM outputs an adjustment characteristic signal responsive to the output of the first switching unit, a multiplier multiplies the output of the ROM by a weighting signal and outputs the result of the multiplication as an adjustment value, a subtractor subtracts the adjustment value from the input luminance signal, an adder adds the adjustment value to the input luminance signal, and a second switching unit selects the output of the subtractor or the output of the adder.

摘要： A liquid-crystal driving circuit has an image data processor that, for example, encodes the present image, decodes the encoded image, delays the encoded image by one frame interval, decodes the delayed encoded image, and uses the two decoded images to generate compensation data for adjusting the gray-scale values in the present image. The encoding process reduces the amount of image data, thereby reducing the size of the frame memory needed to delay the image. The compensation data preferably cause the liquid crystal to reach transmissivity values corresponding to the gray-scale values of the present image within substantially one frame interval. This enables the response speed of the liquid crystal to be controlled accurately.

摘要： A dual-mode image display apparatus includes a black-and-white image display device and a selective filter. The selective filter is caused to assume a first mode in which it sequentially serves as red, green and blue filters, and a second mode in which it transmits all the color components. Thus, the image display apparatus can selectively perform color display or black-and-white display. The selective filter may include variable optical retarders and may be caused to selectively assume the first mode or the second mode through control over the variable optical retarders. The selective filter may alternatively be moved by a motor between a first position in which the filter is in the path of light from the display device to the viewer, and a second position in which the filter is out of the path of light. A power supply controller is also used to conserve power by turning unneeded parts of a color image processing circuit OFF when the display apparatus is in the second mode.
