Abstract: An information processing apparatus includes a display unit, a storage unit, and a control unit. The storage unit contains a plurality of content images to be displayed in a predetermined display order, and a plurality of sample images respectively corresponding to the plurality of content images. The control unit (i) acquires the content image from the storage unit and causes the display unit to display the content image on the screen, and (ii) acquires from the storage unit, upon deciding that a user has instructed to display the sample image, a predetermined number of sample images respectively corresponding to a predetermined number of content images subsequent in the display order to the content image currently displayed on the screen, and causes the display unit to display the sample images on a part of the screen.

Abstract: An information processing apparatus includes a display unit, a storage unit, and a control unit. The control unit reads out a content from the storage unit containing a plurality of contents to be sequentially displayed on a screen of the display unit, and displays the content on the screen. When the screen is tilted and a tilt direction is detected, the control unit displays the content such that the content gradually disappears by moving from a higher side to a lower side along the tilt direction, reads out a content to be displayed next from the storage unit, and displays the next content such that the next content gradually appears by moving from the higher side to the lower side along the tilt direction, over a vacant region in the screen where the preceding content is no longer displayed, and expanding as the preceding content disappears.

Abstract: A back-and-forth displacement detecting device includes: a sensor that detects an amount of displacement of an information processing device and outputs a detection signal indicating the amount of displacement; and a determination section that determines that, if the amount of displacement indicated by the detection signal exceeds a positive threshold value in one of a former period and a latter period which are time periods of predetermined length before and after a point in time when the detection signal indicates an amount of displacement of zero, the amount of displacement indicated by the detection signal in the other period falls below a negative threshold value, and a sum of the amounts of displacement over both the former and latter periods falls within a predetermined range, the information processing device has performed a displacement of back-and-forth movement from an initial state and has returned to the initial state.

Abstract: An information processing device includes a display unit, a movement detection unit, and a control section. The display unit has two display screens of a first screen and a second screen, the second screen being an opposite side of the first screen. The movement detection unit detects a first movement state of the information processing device moving in a direction that the first screen faces and a second movement state of the information processing device moving in a direction that the second screen faces. When the movement detection unit detects the first movement state, the control section allows the first screen to display first content and allows the second screen to display second content. When the movement detection unit detects the second movement state, the control section allows the second display screen to display the first content and allows the first screen to display the second content.

Abstract: An image reading device includes an image reading portion, a detection processing portion, and a combination processing portion. The image reading portion is configured to read image data of a document placed on a document placement surface. The detection processing portion is configured to detect a corner portion of the document on the basis of the image data read by the image reading portion. The combination processing portion is configured to combine the respective image data read by the image reading portion until a total number of the corner portions of the document detected by the detection processing portion becomes a predetermined value.

Abstract: An image processing apparatus includes an input section for inputting image data, and an image processing section for discriminating a marking area out of image data and generating image data of fill-in-blank questions with the marking area converted to a blank answer field. For generation of the image data of fill-in-blank questions, the image processing section recognizes a character count of characters present in the marking area, determines, as an answer-field character count, a character count resulting from adding a margin number to the character count of the marking area, and changes a size of the answer field to a size adapted to the answer-field character count.
