Abstract: PROBLEM TO BE SOLVED: To provide a board surface with a normal luminance level and a brighter emphasis luminance level.
SOLUTION: A user sets an adjustment value ST for changing a board surface luminance level VB. A light source control part 23 changes a light source luminance level BL of a backlight 14 gradually according to the increase/decrease of the adjustment value ST. A liquid crystal control part 26 changes a normal tone level GLo gradually according to the increase/decrease of the adjustment value ST while maintaining an emphasis tone level GLe to the luminance of the normal tone level GLo or higher. In a variable range VR of the adjustment value ST, both of the light source luminance level BL and the tone levels GLo, GLe gradually change according to the increase/decrease of the adjustment value ST. A first region 16 of a liquid crystal element 15 is driven at the normal tone level GLo to display normal information at a normal luminance level VBo. A second region 17 of the liquid crystal element 15 is driven at the emphasis tone level GLe to display emphasis information at a bright emphasis luminance level VBe.

解决方案：用户设置用于改变板表面亮度级VB的调整值ST。 光源控制部23根据调整值ST的增减来逐渐改变背光源14的光源亮度等级BL。 液晶控制部26根据调整值ST的增减逐渐变化正常色调级GLo，同时将强调色调电平GLe保持在正常色调级别GLo以上的亮度。 在调整值ST的可变范围VR中，根据调整值ST的增减，光源亮度等级BL和色调级GLo，GLe都逐渐变化。 以正常色调级GLo驱动液晶元件15的第一区域16，以在正常亮度级别VBo显示正常信息。 以强调色调电平GLe驱动液晶元件15的第二区域17，以在亮度增强亮度级VBe处显示强调信息。 版权所有（C）2010，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To make reduction in an image storage capacity concurrent with improvement in the display accuracy of the physical quantity.
SOLUTION: The maximum meter image 2200 having the maximum dot number Dxmax among the meter images 220 whose dot number from a reference coordinate x0 in the configuration direction Xs is changed in response to the physical quantity to be displayed is stored in an image memory 42. The reduced meter image 2202 having the reduced dot number Dxr smaller than the maximum dot number Dxmax is generated by reducing the maximum meter image 2200. It determines whether the present dot number Dxp and the reduced dot number Dxr are the same or not in response to the present physical quantity. If both are the same, the reduced meter image 2202 is combined with a mask image 221. If both are different, a dot coordinate of the reduced meter image 2202 is shifted by a dot difference ΔD between the dot number Dxp and the dot number Dxr in the direction opposite to the configuration direction Xs. The shifted reduced meter image 2202' is combined with the mask image 221.

解决方案：响应于要显示的物理量而改变来自配置方向Xs上的参考坐标x0的点数的计量图像220中具有最大点数Dxmax的最大计量图像2200被存储在图像中 通过减小最大计量图像2200来生成具有比最大点数Dxmax小的点数Dxr的缩小计量图像2202。它确定当前点数Dxp和缩小点数Dxr是否相同 响应于目前的物理量。 如果两者相同，则缩小的计量图像2202与掩模图像221组合。如果两者不同，则缩小计量图像2202的点坐标偏移点数Dxp和点数Dxr之间的点差ΔD 在与构造方向Xs相反的方向上。 偏移的缩小计量图像2202'与掩模图像221组合。版权所有：（C）2011，JPO＆INPIT
