Abstract: A method for creating frame data used when forming an image by moving a spatial light modulation device including a plurality of plotting element arrays in a scanning direction which forms an inclination angle ? with an arrangement direction of the plotting element arrays, and sequentially inputting the frame data to the spatial light modulation device according to the movement of the device in the scanning direction. The method is based on image data in which pixel data are disposed two-dimensionally in a sub-scanning direction corresponding to the scanning direction, and a main scanning direction orthogonal to the sub-scanning direction, and the frame data are created after performing a deformation process on the image data such that the pixel data corresponding to each of the plotting element arrays (e.g., circled numbers 1 to 6) are disposed in the main scanning direction.

Abstract: An exposure apparatus and method in which an image is formed on a recording medium mounted on a recording stage by irradiating a light beam based on image data from a recording head while the recording head and the recording stage are relatively moved, in the exposure apparatus and method, storing in advance, in a storage section, shift-amount data of a detected displacement of an image-form position with respect to a stage surface of the recording stage in a direction intersecting a direction in which the recording stage moves, which displacement occurs accompanied by movement of the recording stage; carrying out shifting for each of pixels of an image formed by the image data based on the shift-amount data stored in the storage section; and controlling exposure for the recording medium based on image data of the shifted image, is provided to reduce distortion of the image.

Abstract: By selecting a template, a crop boundary (98a) is displayed on an image on a screen. The crop boundary has a corresponding shape to that of a frame of the selected template, and is variable in size while keeping the same shape and being centered on a reference point (98e). Upper and lower horizontal lines (98b, 98c) are also displayed inside the crop boundary to define an internal zone (98d), and the center point on the upper horizontal line is defined as the reference point. By placing the reference point on the top of the head of a human subject contained in the displayed image and then moving the lower horizontal line to align it with the chin, the internal zone is adjusted to the head of the human subject. In cooperation with the movement of the lower reference line, the crop boundary is automatically enlarged or reduced so as to keep the internal zone in a predetermined proportion and position relative to the crop boundary.

Abstract: An exposure apparatus, in which a light beam from a recording head is irradiated on a recording medium mounted on a recording stage, and the recording stage and the recording head are relatively moved, thereby allowing a predetermined image to be exposed on the recording medium, including a displacement detecting section that detects displacement caused by pitching vibration occurring accompanied by movement of the recording stage; a storage section that stores therein displacement-amount data detected by said displacement detecting section; a correction section that corrects, based on the displacement-amount data stored in said storage section, a timing at which the light beam is irradiated from the recording head; and a control section that controls, based on the timing corrected by said correction section, exposure for the recording medium, is provided to correct the displacement and reduce distortion of an image to be formed on the recording medium.

Abstract: Image signals picked up from a reflective original through a reflective scanner (14) are sent to a moiré processing section (46) for eliminating moiré from the image signals. The moiré processing section (46) is provided with a first filter (51) and a second filter (52) that eliminates moiré more than the first filter. The first filter reduces high spatial frequency components of the image and also raises middle spatial frequency components of the image. A selector is provided for selecting the first filter when the original contains characters and grayscale images, or the second filter when the original mainly contains grayscale images. When the original mainly contains characters, both of the first and second filters are not used.
