  When a mobile phone device with a camera is used as a magnifying glass, an imaging operation is performed with the camera lens unit facing a desired subject (for example, a newspaper, a map, a timetable, etc.) to be enlarged in a proximity state. It is necessary to bring the camera-equipped mobile phone device closer to the subject as the image of characters, figures, and the like becomes finer. As a result, external light (sunlight, illumination light, etc.) incident on the subject is It becomes darker because it is blocked by itself, and the finer the character of the subject becomes, the more difficult it is to read. In order to avoid this, if the illumination means for irradiating the subject is specially provided as disclosed in Patent Document 1, the number of parts increases, which is an obstacle to miniaturization and cost reduction. Become.

  The present invention has been made in view of the above-described problems, and its object is to improve the operability when using a mobile phone device equipped with an imaging means as a magnifying glass without impairing downsizing and cost reduction. Is to provide a portable telephone device.

  In order to achieve the above object, a cellular phone device according to the present invention includes an imaging unit, and a main display unit having a display screen capable of displaying an image captured by the imaging unit on the opposite side of the lens mounting surface of the imaging unit. A sub-display unit having a display screen on the lens mounting surface side capable of displaying another image independently of the main display unit, a communication unit, and a key input unit for inputting communication-related information. A magnifying glass mode setting means for setting an operation mode to a magnifying glass mode for enlarging a captured image taken by the imaging means to a magnification equal to or greater than that and displaying the image on the display screen of the main display means, and the magnifying glass Control means for controlling the display screen of the sub-display means to display higher brightness than when the magnifying glass mode is not set when the magnifying glass mode is set by the mode setting means; For example, characterized in that is.

  Furthermore, the cellular phone device according to the present invention is characterized by comprising character information extraction means for extracting character information from the image data of the captured image.

  According to the mobile phone device of the present invention having the above characteristics, character information in an image captured in the magnifying glass mode can be processed or stored as character data instead of image data. Therefore, a large amount of character information can be stored with a small storage capacity, and a search process for a specific character string can be easily performed.

  Furthermore, the cellular phone device according to the present invention includes a keyword storage unit that stores character information input from the key input unit as a keyword, and extracted character information extracted from the image data by the character information extraction unit. A keyword search means for searching for the presence of the keyword stored in the keyword storage means is provided.

  According to the mobile phone device of the present invention having the above characteristics, the keyword search means searches for the presence of a character string that matches the predetermined keyword from the extracted character information in the image captured in the magnifying glass mode. The user can search for a desired character string by simply scanning the lens of the mobile phone device of the present invention toward the subject without staring at the character information on the display screen of the main display means. It becomes. Therefore, in a situation where a subject including text information such as a newspaper is held in one hand and a mobile phone device is forced to be held in the other hand, a desired keyword can be easily used even when used in a crowd such as waiting for a train. It can be used as a magnifying glass to select and enlarge.

  Furthermore, in the mobile phone device according to the present invention, when the keyword is present in the extracted character information by the keyword search means, the location of the keyword is determined by the main display means based on the image data. A display position correcting means for generating a corrected display image located at or near the center of the display screen is provided.

  In the mobile phone device according to the present invention, when the keyword exists in the extracted character information, the keyword search unit identifies the location of the keyword from other parts based on the image data. Search character display correcting means for generating a corrected display image that can be displayed is provided.

  According to the mobile phone device of the present invention having the above two features, the location that matches the keyword in the extracted character information detected by the keyword search means can be easily identified. The keyword search work in is more convenient.

  Furthermore, the cellular phone device according to the present invention is characterized by comprising keyword related information search means for searching for information related to the keyword stored in the keyword storage means.
