Abstract: A mobile terminal has a wide-area wireless communication unit having a communication function of performing wireless communication with a public network, a mobile terminal communication unit having a communication function of performing wireless data communication with a local area network, and an information acquisition unit that performs wireless short-range communication with an information supply device which supplies information. The information acquisition unit performs communication with the information supply device to acquire information indicating whether or not wireless data communication over the local area network is possible near a location where the mobile terminal is located.

Abstract: In a portable terminal, a character string clipping section clips an image of a character string from image data photographed by a screen image pickup device. A character recognition section recognizes the clipped image of the character string and acquires a character code string corresponding to the clipped character string. A character string tracking section sets the acquired character code string as a tracking object character string when the tracking object character string extends beyond the photographable area as well as tracking the tracking object character string or a marker character string ultimately used as an input character string while repeatedly updating the marker character string. A display section highlights the tracking object character string when the tracking object character string extends beyond the photographable area of the image pickup device and displays an arrow showing the relative direction.
