摘要： A method of shortening a lock period of a shared buffer in a data processing system includes a step of securing a copy memory used when nonvolatilizing the contents of the shared buffer, a step of temporarily locking the shared buffer, a step of copying the contents of the shared buffer into the copy memory, a step of unlocking the shared buffer after the completion of the copying step and a step of nonvolatilizing the contents of the copy memory. The shared buffer is locked before the contents thereof are copied into the copy memory and is unlocked after the completion of the copying step and before the nonvolatilization of the contents of the copy memory.

摘要： When two projecting units or more project two pictures or more obtained from video signals and luminance levels of projected pictures at an overlapped portion thereof are adjusted, a picture to be adjusted is selected from the projected pictures. One of processings for adjusting a correction start point of a correction data, a correction end point thereof and an inclination of a correction curve thereof to be used for a picture adjustment is selected. When the positions of a correction start point and/or a correction end point of the correction data are adjusted by using a remote controller unit or the like, a mark data is superposed on the correction start point and/or the correction end point of the correction data to display a mark formed based on the mark data on the screen together with the projected pictures. Thus, the picture is adjusted by displaying the marks together with the projected pictures.

摘要： A video signal processing apparatus includes synchronizing signal separation (31) for extracting a synchronization information of an input video signal, a reference clock signal source (32) for generating a signal having a constant period, phase synchronization control (33) which receives input with a clock signal output from the reference clock signal source and which outputs a phase-locked clock signal at a timing of outputting the synchronization information, and a memory (35) for storing a correction data used for correcting a video signal of one scanning line amount. The correction data is read out from the memory (35) based on the clock signal to process the input video signal. When a synthesized picture is projected, the correction data is a data which permits a luminance level of the video signal of each scanning line amount to be faded in and/or faded out at a start portion and/or an end portion thereof linearly or like a predetermined curve.

摘要： When the input horizontal synchronizing frequency is changed, if the backup data (luminance correction data) corresponding to the horizontal synchronizing frequency is stored in the backup memory unit, then the backup data stored in the backup memory unit is read out from the backup memory unit and then stored in a correction memory unit. If in the above case the backup data corresponding to the changed horizontal synchronizing frequency is not stored in the backup memory unit, a backup data corresponding to the changed horizontal synchronizing frequency is calculated by the correction data calculating unit and the calculated correction data is stored in the correction memory unit and the backup memory unit. When the synthesized picture is projected by using the video signal source 20 which is frequently used, it is possible to quickly carry out various adjustments for the SEM processing.

摘要： An information retrieval system whereby identical search results can be derived irrespective of the kind of DBMS or OS. A keyword normalizing device normalizes a keyword transmitted from a client through a network. A normalized data searching device then searches normalized data in a data storage section for data corresponding to the normalized keyword, and supplies the data to source data acquiring device. The source data acquiring device acquires source data associated with the normalized data supplied thereto, from among source data in the data storage section, and supplies the acquired source data to a sorting device. The sorting device first sorts the normalized data and then the source data in order of the sorted normalized data, and supplies the resulting source data to a source data supply device. The source data supply device transmits the source data to the client through the network.

摘要： An information processing system for normalizing an input character string and storing the normalized character string is provided whereby the required storage capacity can be cut down. Normalizing means normalizes an input character string, for example, , and generates , which is then supplied to restoration information generating means and storing means. The restoration information generating means is supplied also with the original character string , besides the normalized character string , and generates restoration information “F@&” consisting of ASCII characters, which is supplied to storing means. The storing means stores the normalized character string and the restoration information “F@&” in a manner associated with each other. When the normalized character string stored in the storing means is specified, restoring means acquires the corresponding restoration information “F@&” and, based on the acquired information, restores the original information . Consequently, the required storage capacity of the storing means can be cut down, compared with the case of storing also the input character string .
