    Abstract: PROBLEM TO BE SOLVED: To efficiently adjust a white point in the maximum gradation and correct a blue shift of the white point in low gradation by a simple circuit in a digital color display system. SOLUTION: In the adjustment of a white point in the maximum gradation (namely white level), (1) inputted colors whose R, G and B have the maximum gradation value respectively are converted into a different tone of the color based on each conversion value of R, G and B set up by a user. (2) Other inputted colors are gradually decreased in their conversion values, the conversion value of the color whose values of R, G and B by a conversion A are zero, is made to zero, or the conversion value of the color whose values of R or G or B by a conversion B is zero, and is made to zero. In the adjustment of the white point in low gradation, (1) the inputted color whose values of R, G and B are zero, is converted into the different tone of the color based on each conversion value set up by the user. (2) The other inputted colors are gradually decreased in their conversion values, the conversion value of the color whose values of R, G and B are the maximum gradation value, is made to zero, or the conversion value of the color whose values of R or G or B is the maximum gradation value, is made to zero.

    Abstract: METHOD AND APPARATUS FOR INITIALIZING MULTIPLE BUS NETWORKS IN AN INFORMATION HANDLING SYSTEM The present invention provides a program that creates a preliminary map of a multiple bus network used to connect peripheral devices to the central processing unit of an information handling system. This preliminary map is then used by configuration software of the information handling system to locate the peripheral devices in the multiple bus network to configure them. If the physical configuration of the multiple bus network should change in any way, the inventive program can make corresponding changes in the preliminary map without having to rewrite or change the program.

    Abstract: PURPOSE: To prevent erroneous feed of sheets, by providing a first comparing means for comparing a first threshold voltage which is separate from a predetermined detecting voltage and which determines whether a single sheet or overlapping sheets is/are fed, with a detected voltage with respect to a second sheet, so as to deliver an error signal when the detected voltage indicates an overlapping feed. CONSTITUTION: A first detecting means 7 determines whether a detected voltage becomes equal to a predetermined detecting voltage or not while it changes the sensitivity of a photo-detecting device LED and a phototransistor 2 between a first value which exhibits a predetermined detecting voltage during feed of a sheet having a highest light transmittance and a second value which exhibits a predetermined detecting voltage during feed of a sheet having a lowest light transmittance. When the detected voltage becomes equal to the predetermined detecting voltage, the sensitivity of the photo-detecting device LED and the phototransistor are fixed to those obtained at that time, but if the detected voltage does not become equal to the predetermined detecting voltage, an error signal indicating a feed of overlapping sheets is delivered from the first comparing means 1.

    Abstract: PROBLEM TO BE SOLVED: To optimize the workload of the whole system including a graphics chip by decentralizing processing to a host side where a plurality of applications are executed and a panel side. SOLUTION: An image processing system comprises the host side 10 which executes the plurality of applications differing in requested display characteristic and data amount, the panel side 50 which displays images, and a digital interface (I/F) line 49 which transfers image data from the host side 10 to the panel side 50. The digital interface (I/F) line 49 changes a transfer format according to an application that the host is to execute and transfers the image data to the panel side 50, and the panel side 50 expands the image data transferred through the digital interface (I/F) line 49 in a panel memory 52 for expansion and then displays an image on the panel 55.
