Abstract: A drive device for a display medium includes a control unit that controls density of a display color of a predetermined range in which glare may likely occur, of display colors of an image displayed on a reflective type display medium, based on brightness information indicating brightness of irradiation beams irradiated on the display medium so that occurrence of the glare as to the display color of the predetermined range can be suppressed.

Abstract: In the case where, by driving nozzles, test images are formed on paper so that the area of a width predetermined from an end portion in an intersecting direction that intersects with a transporting direction of the paper of a reading area of image reading units is not included in the test images, and the nozzles in an abnormal state are detected by using reading data obtained by reading by the image reading units, the application scope of the reading data applied for detection of an abnormal state is determined so that reading data of each of the test images formed by the nozzles as a detection target of an abnormal state is not repeatedly included with regard to each nozzle, and the nozzles in an abnormal state are detected by using the reading data in the determined application scope.

Abstract: An image forming apparatus includes: plural recording elements that are arrayed along a crossing direction; a reading unit that sequentially reads an image formed on a recording medium; a forming unit that drives the recording elements that are continuously arrayed along the crossing direction so as to form at least one reference image on the recording medium, and then makes timings for driving the recording elements continuously arrayed in the crossing direction different from each other so as to form detection images on the recording medium; and a detection unit that detects the recording element in an abnormal state by changing a size of at least one of a threshold value and a detected value based on the detection image read by the reading unit when the recording element in the abnormal state is detected using the detected value and the threshold value.

Abstract: A liquid droplet ejection apparatus comprising: a conveyor portion that conveys a recording medium to a liquid droplet ejection region by the rotational force of a drive roll; liquid droplet ejection heads that eject liquid droplets onto the recording medium conveyed to the liquid droplet ejection region by the conveyor portion; a feed portion that feeds the recording medium to the conveyor portion at a predetermined feed timing; a detection portion that detects a rotational position of the drive roll; and a control portion that controls the feed timing of the feed portion based on the rotational position that the detection portion has detected, so that when the drive roll reaches a predetermined rotational position, the control portion causes the recording medium to be conveyed to the liquid droplet ejection region and causes the liquid droplet ejection heads to start ejecting the liquid droplets onto the recording medium, is provided.

Abstract: In a droplet ejecting apparatus, a detection pattern output unit drives a droplet ejecting head based on a pulse signal and image information of a detection pattern comprising plural unit patterns so as to form an image of the detection pattern on a recording medium. A correction information generating unit derives a distance between adjacent unit patterns based on the image of a read detection pattern, compares the distance with a distance according to the conveyance velocity of the recording medium by a moving unit, and generates correction information so as to enlarge the pulse width when the derived distance is shorter, and to reduce the pulse width when the derived distance is longer.

Abstract: The present invention provides a droplet ejection device that includes a head, a storage component and an alteration component. At the head, a plurality of nozzles, which eject droplets in accordance with image data representing an image, are arrayed over a width in a main scanning direction which is longer than a recording region width. The head forms a main scanning line with the droplets ejected from the nozzles. At the storage component, inclination information relating to an inclination of the main scanning line formed by the head with respect to a main scanning line that should ideally be formed is pre-stored. The alteration component, in accordance with the inclination information stored at the storage component, alters which nozzles are to eject droplets in accordance with the image data.

Abstract: In an image recording apparatus, reference patterns are provided on a surface of a transport belt that transports a recording medium such as paper attracted thereto to image recording sections defined by recording heads. It is arranged such that the reference patterns are detected while being transported as the transport belt is driven, and a speed change of the transport belt and a position shift in a direction perpendicular to the transporting direction of the transport belt are calculated based on information resulting from the detection, thereby controlling ejection timing and ejection position of ink droplets ejected from the recording heads.

Abstract: An ink jet injection system performs detecting an ink injection condition by ejecting ink droplets so as to form a detecting pattern on a recording medium. When the detecting pattern is formed, the ink droplets are ejected at almost the same position in the state in which the transportation of the recording medium is stopped or a feeding speed of the recording medium is set slower than that during a normal printing operation.
