    • A two-dimensional code reader and program generate edge images based on obtained images, extract candidate regions within these edge images, determine whether or not the extracted candidate regions are valid, determine whether or not characteristic patterns are included in each corresponding region in the original image, and then detects two-dimensional code regions within original images. The two-dimensional code reader and program repeatedly implement generation of edge images based on conversion conditions that correspond to the applicable order among a plurality of conversion condition types in a pre-set order, detection of candidate regions among the generated edge images, determination of whether or not the extracted candidate regions are valid, determination of whether or not characteristic patterns are included in the corresponding regions in the original images that correspond to valid candidate regions, and detection of two-dimensional code regions.

    • The electro-optical device is directly connected to a battery and includes a display panel, a driver, and a voltage adjusting circuit. The driver amplifies an input voltage and supplies the amplified voltage to the display panel. The voltage adjusting circuit includes a plurality of conversion circuits, a switching unit, and a control circuit. The plurality of conversion circuits convert a voltage input from the battery into different voltages and supply the converted voltages to the driver. The switching unit performs switching for supplying the voltage to one of the plurality of conversion circuits. The control circuit controls the switching unit to switch the conversion circuit that supplies the voltage input from the battery when it is detected that a voltage gain of the driver has changed. Thus, the power consumption can be reduced without having an adverse effect on image display.
    • 电光装置直接与电池连接,包括显示面板,驱动器和电压调节电路。 驱动器放大输入电压并将放大的电压提供给显示面板。 电压调节电路包括多个转换电路,开关单元和控制电路。 多个转换电路将从电池输入的电压转换成不同的电压并将转换的电压提供给驱动器。 开关单元执行用于将电压提供给多个转换电路之一的开关。 当检测到驾驶员的电压增益已经改变时,控制电路控制开关单元切换提供来自电池的电压输入的转换电路。 因此,可以降低功耗,而不会对图像显示产生不利影响。
