Abstract: An image projection apparatus includes a projection unit that projects a pattern image on a projection surface; an image capturing unit that captures the projected pattern image; and a corrector that corrects the captured image so that an imaging distortion caused due to image capturing and a projection distortion caused due to projection are corrected. The projection unit projects the corrected captured image at a predetermined position on the projection surface.

Abstract: A projection system includes an image capturing unit which, when a first pattern image is projected on a first projection area, captures an image capture area including the first projection area and at least a portion of a second projection area which overlaps the first projection area to obtain a first captured image and, when a second pattern image is projected on the second projection area, captures the image capture area to obtain a second captured image, a first projection unit which projects a first partial projection-target image extracted from a projection target image based on the first and second captured images and the projection target image on the first projection area, and a second projection unit which projects a second partial projection-target image extracted from the projection target image based on the first and second captured images and the projection target image on the second projection area.

Abstract: An image projecting device for projecting an image on a screen is provided. The image projecting device includes a toppling detecting part that detects a toppling of the image projecting device; a toppling direction detecting part that detects a direction in which the image projecting device topples; and a controlling part that controls the image projecting device such that the image projecting device continues to project the image if the toppling detecting part detects the toppling of the image projecting device and the toppling direction detected by the toppling direction detecting part is directed toward the screen, while the image projecting device stops projecting the image if the toppling direction detected by the toppling direction detecting part is directed away from the screen.

Abstract: Disclosed is a job management system having plural information processing apparatuses connected to each other via a network capable of transmitting and receiving information. The information processing apparatus include a job control unit that selects one of the plural information processing apparatuses to execute a requested job based on user's registration information and equipment information recorded in the plural information processing apparatuses and causes the selected one of the plural information processing apparatuses to execute the requested job.

Abstract: An information processing apparatus includes a character identifying unit that performs character identification with respect to an image in an image data. A file name setting unit sets a file name of the image data based on a character or a character string obtained as a result of the character identification.

Abstract: An image forming apparatus is disclosed that determines whether a computer virus is contained in data and repairs or deletes the data found infected with the computer virus. The apparatus includes a determination section for determining whether data are necessary for operating the apparatus when the data found infected with a computer virus are repaired or deleted; and a restoration section for restoring the data if it is determined that the data are necessary for operating the apparatus.
