    摘要： In a method and an an apparatus for rotating a source image about a reference point on a reference coordinate axis through an arbitrary angle .theta. to obtain a destination image, the source image is represented by a group of reference blocks. Each of the reference blocks has N.times.N pixels and is composed of a square having a side parallel to an axis which is rotated relative to the reference coordinate axis by an angle of .times..theta.. One of vertexes of each of the reference blocks is defined as a rotation center vertex. Each of the reference blocks is rotated about the rotation center vertex by an angle of .theta. to obtain a rotation block. Calculations are made on shift quantities .DELTA.Y and .DELTA.X of the rotation center vertex of each of the rotation blocks. The shift quantities .DELTA.Y and .DELTA.X result from a rotation of the rotation center vertex about the reference point through an angle of .theta.. The shift quantity .DELTA.Y is defined as extending along the reference coordinate axis, and the shift quantity .DELTA.X is defined as extending perpendicular to the reference coordinate axis. The rotation block is translated in a direction of the reference coordinate axis by the shift quantity .DELTA.Y, and is translated in a direction perpendicular to the reference coordinate axis by the shift quantity .DELTA.X to obtain the destination image.

    摘要： Driving voltages of an LED of each color are stored in applied voltage storage register 11, 12 or 13, and the LED of each color is driven with independent driving voltage, whereby current consumption is reduced. Further, data in applied voltage storage registers 11, 12 and 13 is made rewritable via storage value setting bus 14, and when there are fluctuations in minimum emission voltage in actually mounted LEDs due to individual differences, voltages to store in the applied voltage storage registers 11, 12 and 13 can be changed as appropriate corresponding to the fluctuations.

    摘要： A voltage with a predetermined pattern is applied to liquid crystals to drive the liquid crystals during a unit drive period of the liquid crystals and an application pattern according to the gradation data is set taking into account a value obtained by integrating the amount of transmitted light of liquid crystals at various points in time when each application pattern is applied to the liquid crystals. This allows a fine gradation display even if the liquid crystals are driven by only ON/OFF of a maximum rated voltage. As a result, it is possible to drive the liquid crystals at high speed and produce a multi-gradation display.
