20100231597 | CALCULATOR AND COMPUTER-READABLE MEDIUM - A calculator is provided. The calculator includes: a display unit having a touch panel; a recognition unit configured to: (i) recognize a numerical expression which is handwritten on the touch panel; (ii) convert the handwritten numerical expression in a text format; and (iii) display the text-converted numerical expression on the display unit; and an erasing unit configured to: if a part of the text-converted numerical expression is erroneously recognized and the erroneously-recognized part is specified, (i) erase the erroneously-recognized part and a part of the handwritten numerical expression corresponding to the erroneously recognized part. If information is handwritten again in the erased part of the handwritten numerical expression, the recognition unit recognizes the handwritten information again, and then the erroneously-recognized part of the text-converted numerical expression is corrected. | 09-16-2010 |
20110227946 | GRAPH DISPLAY APPARATUS, RECORDING MEDIUM ON WHICH PROGRAM IS RECORDED AND GRAPH DISPLAY METHOD - A graph display apparatus including: a display unit; a graph formula input unit for receiving input of a graph formula; a coordinate system setting unit for setting a display range of a coordinate system and a scale interval on a coordinate axis in the coordinate system; a coordinate system display controlling unit for making the display unit display the coordinate axis, and display scales and scale values at the scale interval, the coordinate system display controlling unit including a scale value display controlling unit for detecting overlapping of the scale values to be displayed, and, when the scale values overlap, making the display unit display only scale values of scales at both ends among the scales to be displayed on the coordinate axis; and a graph display controlling unit for making the display unit display a graph of the graph formula. | 09-22-2011 |
20120188274 | GRAPHIC DISPLAY APPARATUS, GRAPHIC DISPLAY METHOD AND RECORDING MEDIUM IN WHICH GRAPHIC DISPLAY PROGRAM IS RECORDED - Disclosed is a graphic display apparatus including a display unit, a reference object length storage unit in which specified parts of reference objects and actual lengths of the specified parts are stored, an image storage unit in which images are stored, an image display control unit which displays a specified image which is specified based on a user's operation in the display unit, a specified image part setting unit which detects a specified part of a reference object in the specified image and sets the detected specified part as a specified image part, a coordinate system setting unit which superimposes a coordinate system on the specified image and sets a display range of the coordinate system based on an actual length of the specified image part, and a graphic display control unit which superimposes and displays a graphic on the specified image. | 07-26-2012 |
20120313837 | PRESENTATION SYSTEM AND DISPLAY TERMINAL USED IN THE PRESENTATION SYSTEM - A presentation system comprising a presenter terminal and at least one audience terminal which is connected to the presenter terminal to communicate with each other;

20130024817 | DATA DISPLAY APPARATUS, DATA DISPLAY METHOD, AND RECORDING MEDIUM STORING DATA DISPLAY CONTROL PROGRAM - A data display apparatus that has a display unit includes an application storage unit, a display controller, an available-application-type detector, and an available-application-type display controller. The application storage unit stores a type of application. The display controller displays a plurality of pieces of data in a data display area on the display unit. The available-application-type detector detects a type of available application, for which each piece of data displayed in the data display area is usable, in the type of application stored in the application storage unit. The available-application-type display controller displays the type of available application for each piece of data, with the type of available application being associated with each piece of data, based on a detection result obtained by the available-application-type detector. | 01-24-2013 |
20140285528 | GRAPH DISPLAY CONTROL APPARATUS, GRAPH DISPLAY CONTROL METHOD AND NON-TRANSITORY STORAGE MEDIUM HAVING STORED THEREON GRAPH DISPLAY CONTROL PROGRAM - A graph display control apparatus includes a figure display control unit, a graph figure change unit, a coordinate value calculation unit and a figure prominent display control unit. The figure display control unit sets a coordinate system to a display unit and displays (i) a first graph figure and (ii) a coordinate axis or a second graph figure in the system. The graph figure change unit moves or transforms the first graph figure in the system in response to a user operation to change the first graph figure. The coordinate value calculation unit detects an intersection point of (i) the changed first graph figure and (ii) the coordinate axis or the second graph figure and calculates a coordinate value of the intersection point. The figure prominent display control unit prominently displays the changed first graph figure when the coordinate value is an integer. | 09-25-2014 |
20140297702 | MATHEMATICAL EXPRESSION DISPLAY CONTROL APPARATUS, MATHEMATICAL EXPRESSION DISPLAY CONTROL METHOD, AND COMPUTER READABLE MEDIUM RECORDING MATHEMATICAL EXPRESSION DISPLAY CONTROL PROGRAM - A mathematical expression display control apparatus includes a mathematical expression input unit, a mathematical expression display control unit, a cursor display control unit, an inverse number function input unit, an inverse number target detection unit and an inverse number display control unit. The mathematical expression input unit recognizes a mathematical expression. The mathematical expression display control unit displays the recognized mathematical expression on a display unit. The cursor display control unit moves and displays a cursor in the displayed mathematical expression. The inverse number function input unit recognizes an inverse number function. The inverse number target detection unit detects a chunk region of the mathematical expression as a target of the inverse number function. The inverse number display control unit replaces the detected chunk region with a fraction having the detected chunk region as a denominator and 1 as a numerator to display. | 10-02-2014 |
20140365954 | ELECTRONIC DEVICE, GRAPH DISPLAY METHOD AND STORAGE MEDIUM - An electronic device includes a display device and a processor. The display device includes a touch panel. The processor (i) generates a graph image to be displayed on the display device, (ii) when the generated graph image is displayed on the display device, acquires an object specified by a user, the object being contained in the graph image, and (iii) when the user performs a touch operation on the displayed graph image, changes a display style of the graph image according to a type of the acquired object and displays the graph image in the changed display style. | 12-11-2014 |
