    • In a non-reading mode, a bar code is detected by irradiating it with a laser beam from a laser source, power consumption of which is reduced, and it is determined whether or not the detected bar code is correct. The mode is changed from the non-reading mode to a reading mode in which the laser source operates at substantially full power if it is determined that the code symbol is correct. The non-reading mode continues if it is determined that the code symbol is not correct. This enables an auto-trigger function that triggers reading of the bar code automatically. Therefore, it is possible to eliminate conventional parts and/or special-purpose circuits for realizing the auto-trigger function so that the optical-information-reading apparatus can be downsized.
    • 在非读取模式下,通过用来自激光源的激光束照射条形码来检测条形码,其功耗降低,并且确定检测到的条形码是否正确。 如果确定代码符号正确,则该模式从非读取模式改变为读取模式,其中激光源以基本上全部功率运行。 如果确定代码符号不正确,则非读取模式继续。 这将启用自动触发功能,自动触发条形码读取。 因此,可以消除用于实现自动触发功能的常规部件和/或专用电路,从而可以减小光学信息读取装置的尺寸。

    • A realistic image display system includes an input section, a storage section, a light source data specifying section, a parameter specifying section, a polygon generating section, an image generating section, and a display section. The polygon generating section generates a set of polygons indicating the effects of a light source on three-dimensional space on the basis of three-dimensional object data including a three-dimensional object, the location of the object in the three-dimensional space, and a three-dimensional object attribute, and parameters specified at the parameter specifying section. The image generating section performs coloring on the three-dimensional object and the set of polygons on the basis of the three-dimensional object data, the light source data, and the parameters, thereby generating a display image.
