    • In a monochromatic image display system, the number of tone levels which can be expressed is multiplied. As a display device, a liquid crystal panel 40 which can express each picture element 41 of a monochromatic image by three cells 41a, 41b and 41c is employed. A tone number conversion processing means 20 carries out a tone number conversion processing on an input original image signal Sorig according to the maximum number of tone levels which can be expressed by the liquid crystal panel 40, thereby obtaining a monochromatic image signal So. Luminance of the monochromatic image signal So is allotted to the cells 41a, 41b and 41c. Time modulation is carried out on each cell by a time modulation means 12 which can express four tone levels (but tone level 0) so that each cell outputs allotted luminance. In this manner, the liquid crystal panel 40 can express thirteen tone levels (4×3+1=13) in total (tone level 0 inclusive).
    • 在单色图像显示系统中,可以表达的音调电平的数量相乘。 作为显示装置,采用能够通过三个单元41a,41b和41c来表示单色图像的每个图像元素41的液晶面板40。 音数转换处理装置20根据可由液晶面板40表示的最大音调电平数,对输入的原始图像信号Sorig执行音调转换处理,从而获得单色图像信号So。 单色图像信号So的亮度分配给单元41a,41b和41c。 通过时间调制装置12对每个小区执行时间调制,时间调制装置12可以表示四个音调电平(但是音调电平0),使得每个单元输出分配的亮度。 以这种方式,液晶面板40可以总共显示十三个音调电平(4×3 + 1 = 13)(音调级别0包括在内)。

    • A cognitive function training unit including an eye-target showing unit for showing a movable eye-target on a display disposed in front of the subject's eye, an eye movement measuring unit for measuring a position and/or movement of the subject's eye, and a judgment unit for judging whether or not the subject can fixedly look at or follow the eye-target based on the position and/or the movement of the eye-target shown on the display and the position and/or the movement of the subject's eye measured by the eye movement measuring unit, and the eye-target showing unit shows the eye-target repeatedly while changing the position and/or the movement of the eye-target according to a judgment result of the judgment unit. Therefore, it is possible to show a suitable eye-target according to a symptom of a patient, whereby it is possible to conduct training efficiently.
