    摘要: A ink transfer printer includes a thermal head having an array of heating elements, a film having through-holes facing the heating elements, an ink space formed between the thermal head and the film, and a mechanism which brings a recording medium in contact with the film. When the heating element generates heat, the ink is transmitted through the through-hole of the film and is transferred to the recording medium. An ink amount controller is provided in the ink space, which controls the amount of ink transmitted through the through-hole to the recording medium.

    摘要: An image scanning device is provided that includes an imaging lens, a linear image sensor that outputs a line image signal, a rotatable scanning mirror that deflects light towards the image sensor through the imaging lens, a scanning system for rotating the scanning mirror to scan a two-dimensional image, a focusing system that drives the imaging lens according to a position of the scanning mirror to maintain an in-focus image, and a magnification correction system which compensates for changes of magnification of the line image due to the driving of the imaging lens, such that distortion of the two-dimensional image is reduced. In particular, based on the assumption that an object is a flat surface that is perpendicular to an optical axis of the image scanning device, the magnification correction system compensates for the changes of magnification by calculating a difference between a reference magnification and a current magnification, and replaces a corresponding number of pixels from the line image signal with compensation pixels.

    摘要: An apparatus for displaying a 3-D image has a projector, and a projection controller. The projector has a projection optical system, and projects a series of 2-D images on different projected-positions in a depth direction, in order, by using light passing through the projection optical system. Each 2-D image is formed on the basis of section-views of a 3-D object in the depth-direction. The projector repeatedly and successively projects the series of 2-D images so as to cause an afterimage-effect. In the present invention, the projection controller adjusts a projection-timing of the series of 2-D images, and controls the projection optical system in accordance with the projection-timing so as to focus each 2-D image and maintain a magnification of the series of 2-D images constant.

    摘要: An image reading device is provided that includes a linear image sensor (such as a CCD), a contrast detecting system, and a focus condition judging system. The focus condition judging system is arranged to detect when the image reading device is in an in-focus condition based on output of the image sensor. Further, a driving mechanism is provided that moves an imaging lens or the image sensor, while the contrast detecting system monitors contrast data calculated from the output of the image sensor. An in-focus condition may be detected when the contrast data substantially reaches a maximum value. The maximum value may be a first maximum value detected during the movement controlled by the driving mechanism or may be a maximum value over a predetermined range of the controlled movement.
