Abstract: A mobile terminal device includes: a housing; a touch panel-equipped display section; a sensor; and a control unit including a processor and, upon execution of a control program by the processor, functioning as a display control section, an operating region decision section, an operating region storage section, a specific inclination determination section, and a display change section. The operating region decision section determines, during holding of the housing with a user's one hand, an operating region on the screen of the display section reachable with an operating finger of the one hand from a trace of points of touch with the operating finger. When an inclination of the housing detected by the sensor is determined to be a specific inclination toward the operating finger by the specific inclination determination section, the display change section moves and displays a plurality of on-screen objects into and within the operating region.

Abstract: A crease detecting unit 13 detects a crease in a document image. A toner peeling detecting unit (a) detects as a toner peeling part a pixel area on the crease, the pixel area (a1) having a width of the predetermined number of pixels in a direction perpendicular to the crease, (a2) having a background color, and (a3) of which both sides are adjacent to at least two pixels in a direction perpendicular to the crease, the at least two pixels having a color other than the back ground color, and (b) corrects a pixel value of the toner peeling part on the basis of pixel values of at least two pixels adjacent to both sides of the pixel area.

Abstract: An electronic system includes an electronic apparatus and a mobile terminal that transmits instruction signals to the electronic apparatus to allow the electronic apparatus to perform a plurality of various functions. When a plurality of the mobile terminals exist within a predetermined distance and transmit the respective instruction signals for allowing the electronic apparatus to perform the same function, an operation control section of the electronic apparatus performs the function indicated by the instruction signal transmitted from, of the plurality of the mobile terminals, the mobile terminal located nearest to the electronic apparatus.

Abstract: A mobile terminal includes a communication section, a communication control section, a display section, a display control section, an operation acceptance section, and a location detecting section. The location detecting section determines whether a location of the mobile terminal is approaching or leaving an electronic apparatus. If the location detecting section determines that the location of the mobile terminal is approaching the electronic apparatus, the display control section increases a first threshold value and uses the increased first threshold value to execute processing for changing contents of a plurality of operating buttons provided on an operation screen.

Abstract: In a mobile terminal, a plurality of operating buttons associated with functions performable by an electronic apparatus are provided on an operation screen. A storage section previously stores correspondence information related to the functions performable by the electronic apparatus and indicating correspondence between a relative location between the mobile terminal and the electronic apparatus and a set of functions available depending on the relative location. A first control section allows a display section to display a setting screen for accepting a change in the correspondence information. Based on an operation accepted by an acceptance section on the setting screen, a second control section changes the correspondence information and allows a storage section to store the changed correspondence information.

Abstract: An image forming apparatus includes a scanning section, a storage section, an image forming section, and a control section. The scanning section scans an image formed on a first side of the recording medium to obtain scanned image data. The storage section stores therein specific information data indicating a specific image or a specific character string. The control section controls the scanning section and the image forming section. The image forming section forms an image based on input image data on a second side of the recording medium. The control section determines whether or not the input image data includes the specific information data and the scanned image data includes the specific information data and determines based on a result of the determination whether or not to control the image forming section to form a masking image on the first side of the recording medium.

Abstract: In an image processing apparatus, a specific local gradation pattern detecting unit detects a specific local gradation pattern in a density distribution of a pixel array in a secondary scanning direction at each one of plural sampling positions along a primary scanning direction in a document image. A crease detecting unit detects a crease on the basis of positions in the primary scanning direction and positions in the secondary scanning direction of plural specific local gradation patterns detected for the plural sampling positions along the primary scanning direction. A crease removing unit removes the detected crease. The specific local gradation pattern has a density distribution that monotonically increases from a background density to a local peak density and monotonically decreases from the local peak density to the background density in the secondary scanning direction.
