Abstract: A power source pole of the present application includes a pole main body, a solar cell module, a storage battery, and a power source side connector. The solar cell module and the power source side connector are located outside the pole main body. The storage battery is charged with electric power generated by the solar cell module. The electric power of the storage battery is output to the outside through the power source side connector. An illumination apparatus of the present application includes the power source pole of the present application and a light emission unit. A multifunctional apparatus of the present application includes the power source pole of the present application and an outside unit.

Abstract: An image display device includes a memory component, a color specification component and a display component. The memory component stores frame data that forms a display image, a color table that stores color data for each selection condition with the color data being indicative of a plurality of colors specified to the frame data, and reference data that associates the selection condition with the color data of the color table. The color specification component specifies the color data to the frame data based on the reference data according to the selection condition. The display component generates the display image based on the frame data and the color data.

Abstract: There are provided a display device, a display system, a method of controlling such a display device and a signal processing device in which a plurality of information devices can be simultaneously connected, information stored in the information devices is displayed and the information can easily be exchanged. In display devices 1, 1A and 1B, a display system and a method of controlling such display devices, a plurality of information devices A, B and C are simultaneously connected, information on content is displayed at one time, a content type corresponding to each of information devices is confirmed, the information device to which the selected content can be copied is determined and copying processing is started between the copying source and the copying destination. In a signal processing device 10, these functions are provided, and a conventional TV device can be used as a display device.

Abstract: A TV receiver as an electronic device is connected to an adjustment device by an exclusive cable of two transmission lines connected to an HDMI connection terminal. In adjustment mode, a main microcomputer of the TV receiver sends a signal to the adjustment device through a transmission line including an HPD line with an HPD port serving as an output port for the signal, and receives a signal from the adjustment device through a transmission line including a +5V line with a +5V port serving as an input port for the signal. Thus, the microcomputer can perform adjustment processes by receiving product information and various set values from the adjustment device to store them in a memory, and by sending the stored various values to the adjustment device, without providing a UART port, making it possible to reduce manufacturing cost.
