摘要： PROBLEM TO BE SOLVED: To provide an information processor without inconvenience such as that a coordinate input to a hidden area is delayed, etc., during a picture scroll even when display resolution of two display devices are different by selecting the display data and displaying them so that a reduced display picture of the display device with large resolution is displayed on the display device with small resolution. SOLUTION: The display data are selected to be displayed so that the reduced display picture of the display device 110 with the large resolution is displayed on the display device 108 with the small resolution. Further, when a coordinate input device 111 that an input is performed by directly instructing the display picture is attached to the display device 108 with the small resolution, since a detected coordinate is different from an intended instructive coordinate value, by performing the control so as to multiply the detected coordinate by a reciprocal number of a reduction rate, the coordinate value is made to coincide with the detected coordinate. For instance, even when the coordinate is instructed on the central part (central part of 640×480 of reduced display) of the display device 108 with the small resolution, a cursor display position becomes the central part of 640×240. Then, the Y value of the read in display data is doubled.

摘要： PROBLEM TO BE SOLVED: To provide a display control device which can perform display control without increasing data transfer speed independently of increasing resolution by using two displays. SOLUTION: Reduction color data of one dot in which data quantity transferred to each display 127, 128 are respectively reduced to 1/2 is synthesized as one group of data in a multi-mode, and stored in a display memory 107. Data read out from a display memory is outputted as it is in an internal palette 110 of a display controller 105, separated to data corresponding to each display by a bus controller 119, transferred to an external palette circuit 122, converted to display data by corresponding palettes 123, 124, and sent to each display. In a single mode, color data in which data reduction is not performed is stored in a display memory, read out color data is displayed on only a LCD 127 by the bus controller 119 through the palette 123 without separating data.

摘要： PROBLEM TO BE SOLVED: To provide a liquid crystal display device which displays clear video by obtaining an appropriate contrast in accordance with video data. SOLUTION: Video characteristic (luminance distribution, maximum/minimum values and an average value) are obtained in an arbitrary interval from R, G and B video data inputted to input video characteristic detection sections 13 to 15 or luminance data and the characteristics are inputted to a microcomputer 23 through a microcomputer controlling section 24. The microcomputer 23 analyzes the data and outputs broken line point/master data and broken point correction data to broken line point generating sections 16 to 18 through a microcomputer control section 24 in order to obtain a good display condition. The sections 16 to 18 output broken line point data, that determine an output gradation characteristic, to between-points gradation computing section 19 to 21. In the sections 19 to 21 conduct computing processes using the broken line point data and the inputted R, G and B video data, obtain output gradation data between point and output the data to a display panel 4.
