摘要： For dividing an image and recording divided images on a photosensitive film with a plurality of laser beams, an auxiliary scanning speed is reduced in the vicinity of junctions between adjacent ones of the divided images to adjust the intervals between main scanning lines, and each of the main scanning lines is divided into divided main scanning lines in a main scanning direction, and the divided main scanning lines are formed separately in an auxiliary scanning direction. With such a correcting process, a high-quality image free of striped artifacts and inclination differences of main scanning lines can be recorded on the photosensitive film.

摘要： A light quantity adjusting method is used for driving a light emitting device with two drive current levels. The drive current levels are controlled by the first set data and the second set data, respectively. First, a resolution ratio and light quantity characteristics are stored. The resolution ratio represents a ratio between a drive current setting resolution of the first set data and a drive current setting resolution of the second set data. The light quantity characteristics represents a relationship between the first set data and a light emission quantity of the light emitting device. A value in the first set data is obtained as a first set value through adjustment for a quantity of light. Next, a change amount, from the first set value in the first set data is calculated using the light quantity characteristics. The calculated change amount is converted into a value in the second set data as a second set value using the resolution ratio.

The method includes: measuring displacement amounts of positions of light beam spots on the image recording surface generated due to a change in optical magnification of the optical system; changing a light-emitting timing at a time of start of scanning in the scanning direction, on the basis of a displacement amount in the scanning direction; and changing a resolution in the direction intersecting the scanning direction, on the basis of a displacement amount in the direction intersecting the scanning direction.

摘要： Two-dimensional image data is divided into two-dimensional image data of numbers of main scanning lines depending on intervals between laser beams. While effective signals are high in level, the divided two-dimensional image data simultaneously start being outputted as effective image data. While effective signals are low in level, the two-dimensional image data are made ineffective. In this manner, recording ranges covered by the laser beams are adjusted to record a two-dimensional image. A high-quality two-dimensional image can thus be recorded at a high speed in a desired recording position on a photosensitive medium by exposure to light beams with an inexpensive arrangement without the need for a highly accurate adjusting process and a highly accurate adjusting mechanism.

摘要： 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 θ 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.
