With this contrivance, the program information sorted out in an easy-to-view form and thus printed, can be obtained.

Abstract: A display apparatus has a plurality unit pixels each divided into a least three sub-pixels for displaying a halftone. The at least three sub-pixels have mutually different areas, so that one sub-pixel among the at least three sub-pixels has a maximum area which does not exceed a total area of the remaining sub-pixels. As a result, it is possible to obviate a so-called linear defect occurring in a multi-level gradational display by suppressing the shift of gravity center of light spots and change in sub-pixel arrangement pattern in displaying slightly different gradation levels.

Abstract: An image processing apparatus obtains, on the basis of information of input resolution of input image data and information of output resolution to be obtained after transformation of resolution, a ratio of the input resolution to the output resolution as an integral ratio M:N having no common divisor, decides, in units of the N number of pixels of output image data, which of a first resolution transforming process and a second resolution transforming process is to be used for each of the N number of pixels of output image data, and performs the first resolution transforming process and the second resolution transforming process on the input image data on the basis of a result of this decision, to obtain the output image data.

Abstract: A receiver for detecting a predetermined SD broadcast program transmitted at a high speed using an HD broadcast channel, storing the detected predetermined program in a storage, and reproducing a broadcast signal of the predetermined program stored in the storage at a speed faster than the normal reproduction speed.

For that purpose, in this system, the seller side acquires via a network information on electronic contents that the buyer side wanting to purchase arbitrary electronic contents desires to buy and displays it as a list by using a WWW browser, and in the case where electronic contents desired to sell are among the electronic contents desired to buy listed in the displayed list, the seller side provides the electronic contents to the buyer side via the network.

Abstract: A display control device detects the state of an input video signal, sets the display mode of a display device among n predetermined display modes corresponding to different states of the input video signal on the basis of the detection output, and controls the display operation of the display device in accordance with the set mode. When the detected state of the input video signal does not match any of the n predetermined display modes, the display mode of the display device is set to be one of the n predetermined display modes.

Abstract: A display control apparatus having a plurality of different display modes for displaying a plurality of types of image signals corresponding to different resolutions and dot clocks, includes a discrimination circuit for displaying the display mode of the currently displayed image signal, and a selection circuit for selecting on-screen display data to be displayed on the basis of the display mode discriminated by the discrimination circuit. In addition, an input circuit inputs the on-screen display data selected by the selection circuit in place of the currently displayed image data, and an output circuit outputs the on-screen display data input by the input circuit in the display mode of the image signal.

Abstract: A display control method and apparatus for quantizes input data to binary or multivalued data and delivers the quantized data to a display device such as a matrix panel display. When input data is quantized as by the error-diffusion method and displayed, an area in which there is no change in the display is scanned by multi-interlacing, whereas an area in which there is a change in the display is scanned preferentially and in interlaced fashion. As a result, a flicker-free image having a high picture quality can be displayed at high speed. Further, error produced by the error-diffusion method is reset at a prescribed line and, at the time of the error resetting operation, error-diffusion processing is executed from a line located several lines earlier, thereby preventing the occurrence of sparkling noise and making it possible to display an image of a high picture quality in which the continuity of error-diffusion processing is maintained.

For this purpose there is disclosed a display apparatus provided with a clock generating circuit including a PLL circuit and adapted to generate a clock signal which is phase synchronized with the input video signal, and a display circuit for displaying the image relating to the input video signal utilizing the clock signal generated by the clock generating circuit. A detection circuit detects the state of the input video signal according to whether the PLL circuit is in the locked state.

Abstract: An image processor includes a quantizing unit which quantizes input image data to data of at least three or more levels. A memory stores the quantized data on a picture unit basis, and an output unit outputs the stored image on the picture unit basis. The quantizing unit quantizes the image data of a present picture in accordance with the quantized data of a previous picture stored in the memory, and quantizes the input image data of one pixel to the data of three or more levels by using a plurality of threshold values each including an upper threshold value, a standard threshold value and a lower threshold value.

Abstract: A display using interlaced scanning or a display using a partial rewriting method, in which only a part of a picture frame of a display device is rewritten and displayed, is combined with an error diffusion method resulting in an image displayed on the display device being made to be continuous. More specifically, when processing data of the first line of one band (comprising a plurality of lines) by the error diffusion method, error data produced when the final line of the immediately preceding band has been processed is stored in a memory, and error data stored in the memory is used. When processing data of the first line of a band by the error diffusion method, processing is started from data of a line a few lines above the first line.

Abstract: A display control apparatus of a display device which uses a ferroelectric liquid crystal as an operational medium to display or update image data comprises a data storage unit to store data which is displayed on a display device, a supplying unit to supply data to the data storage unit, a detector to detect a difference between the data supplied to the supplying unit and the data displayed at present on the display device, a memory to store data indicative of the result of the detection by the detector, a controller to supply the data stored in the data storage unit to the display device on the basis of the result of the detection stored in the memory, and a counter to count the number of different bits of the line detected by the detector. The detector detects such a difference for every line of the display device. The controller preferentially supplies the data to the display device in descending order of the number of bits counted for each line.
