Abstract: An image signal processor and a method for processing an image signal thereof are disclosed. When the image signal processor executes an automatic chroma gain control (ACC), the image signal processor adjusts a variable rate of ACC gain according to a size of an input color signal to reduce a time for processing the ACC. Even if a difference between the size of the input color signal and the size of a reference color signal is large, the ACC is rapidly processed. As a result, transient phenomenon disappears from a screen.

Abstract: In one aspect a transmission system with a transmitter which can be connected to a video source and a receiver linked to the transmitter via at least four circuit pairs, to which receiver a playback device can be connected is provided. Data is usually exchanged digitally between a graphics card in a personal computer and an LCD display module. The personal computer transmits a digital R, G, B video signal to the LCD display module via a special, so-called DVI (Digital Video Interface) cable. This DVI cable is also provided to transmit so-called DDC (Display Data Channel) data, which particularly comprises specification information of the LCD display module. A transmission system is proposed, which simplifies a connection of an LCD display module to a personal computer and with which the DVI cable can be dispensed with.

Abstract: A video synchronization signal removal circuit in which a synchronization signal component of an incoming video signal is detected whereupon a reference signal corresponding to a black video level is substituted substantially during the synchronization signal interval.

Abstract: A method of displaying an image including receiving a plurality of corresponding to an image data, wherein each of the plurality of frames includes a plurality of color sub-frames; sequentially displaying the color sub-frames corresponding to a first frame in a first color sequence over time; and displaying the sub-frames corresponding to a second frame following the first frame in a second color sequence over time, wherein the first color sequence is different from the second color sequence.

Abstract: A color frame identifier circuit generates a pseudo-subcarrier signal and compares the pseudo-subcarrier signal to a sliced color burst of at least one selected line in a video frame. Based on this comparison, a processing circuit determines the color frame.

Abstract: A method for detecting dynamic video pixels by using adaptive counter threshold values according to field difference value of the frame in the video, thereby to determine whether the frame is an interlaced frame or a progressive frame and to eliminate incorrect judgements resulting from field difference and to improve accuracy of frame determination.

Abstract: A calendar selling system comprises a server that stores information of a plurality of pictures and a terminal that receives information of the plurality of pictures from the server and shows the information to a user, and the user selects pictures for a calendar from the plurality of pictures according to the information with the terminal to order the calendar. The calendar selling system also comprises a printing office that receives information of the pictures selected by the user from the server, prints the calendar with the pictures selected by the user and dates set by the user or automatically set according to the date of the order, delivers the calendar to the user and bills the user. Therefore, the desired calendar can be purchased all through the year and delivered to the user quickly.

Abstract: Television uses a composite video signal to transmit color information. A color signal filter (12, 16) selects one of a plurality of candidate color signals derived from the composite video signal. The plurality comprises a first and second difference signal between the information for a central line and for lines on a first side and a second side of the central line respectively. The color signal filter promotes selection of the first difference signal over the second difference signal and vice versa according to whether the composite video signal represents an image with an edge on the second or first side of the central line respectively at the horizontal position. The apparatus contains circuitry (14) to detect a thin line configuration where data from the composite video signal for the central line is extreme relative to corresponding data for first and second lines on the first and second side respectively at the horizontal position.

Abstract: The image signal processing apparatus for a prompter is intended to improve ease in viewing an image when using clock frequencies synchronized to the sub-carriers of the four-field sequence. That is, the sub-carriers with different phases are separated from the video signal, in-phase clock signals from which phase shift in the sub-carriers is eliminated are generated by a timing signal generator circuit, and image data in all four fields are processed with the clock signals. This reduces flickering on the screen. The timing signal processing circuit may generate in-phase clock signals for odd fields and in-phase clock signals for even fields, and shift the phase between them by 180.degree. so that pixels in an oblique direction are obliquely aligned with half pixel shift between both clock signals. This is particularly effective for an oblique line.

Abstract: An input signal is inputted to an A/D converter through an amplifier and is converted into a digital input signal. A vertical synchronizing pulse and a horizontal synchronizing pulse are taken out of the output signal of the amplifier by means of a TV synchronizing separator and inputted to a trigger gate and selector circuit. A delay timer and a timing control circuit are operated by a selected synchronizing pulse, and the data applied with A/D conversion are stored in a memory in accordance with a set delay time and sampling synchronization. The stored data are read by means of a CPU circuit. The state of a burst signal is decided by the CPU circuit, and separation of eight fields is performed by combining that state with a set state of the TV synchronizing separator.
