Abstract: An input device includes: a display unit indicating an image of an input position; a contact position detecting unit detecting a position of an object brought into contact with a contact detecting layer provided on a display layer of the display unit; a contact strength detecting unit detecting contact strength of the object brought into contact with the contact detecting layer; and a contact state determining unit which extracts a feature quantity of the detected contact strength, compares the extracted feature quantity with a predetermined threshold, and determines a contact state of the object.

Abstract: An electronic device includes a first display device having a display screen, an input device for acquiring a first information indicating a touch position on the display screen, a storing device for storing emulation information used to convert the first information into a second information indicating a touch position on an operating system, and a converting means for converting the first information indicating the touch position acquired by the input device into the second information indicating the touch position on the operating system, based on the emulation information stored in the storing device.

Abstract: An electronic apparatus includes first and second display devices having first and second display screens held in first and second housings, respectively. The second display screen is provided with a sensor which generates an output signal determining an input area in response to an external predetermined input to the second display screen. The first and second housings are connected together by a connecting mechanism so that an opening angle between the first and second housings can be adjusted. A first interface image is displayed on the second display screen. An instruction input to the interface image is determined on the basis of a sensor output signal. In response to the instruction input, a second display image is displayed in place of the first display image. In response to the instruction input, a second interface image is displayed in place of the first interface image.

Abstract: This apparatus calculates a direction of a light source (the sun) in a coordinate system having a 3D geometrical model of an object placed therein from geographic information on an object and a shooting time of image data, and detects a shadow region cast on the 3D geometrical model by a beam from a light source direction so as to identify the shadow region in the image data based on correspondence information. It uses a predetermined reflection model to estimate effects of shadings caused to the 3D geometrical model and determines a parameter of a reflection model suited to estimated shadings. And it performs calculation for removing the effects of the shadows and shadings by using the determined parameter from pixel values sampled from the image data so as to fit the calculated pixel values in the 3D geometrical model and generate a texture model.
