The laser source is not modulated according to image data for the second part of the first one of the sweeps. During the first part of a second one of the associated sweeps of the beam, the laser source is not modulated based upon image data. However, the laser source is modulated based upon the second part of the line of image data during the second part of the second one of the sweeps.

摘要： A scanner is provided with a variable aperture lens system. High resolution scans use a relatively small aperture size, and scanning speed is relatively slow. Low resolution scans use a relatively large aperture size, and scanning speed is increased. Fast scans are limited to lower sampling rates, which in turn permit more optical blurring relative to high sampling rates. Accordingly, the incremental cost of the larger aperture is minimized by permitting the lens aberrations specifications to be relaxed at larger apertures. Preferably, an electronic variable aperture is provided, for example, by use of electronically controlled polarization plates or by use of electrochromic substances.
摘要翻译：扫描器设置有可变孔径透镜系统。高分辨率扫描使用相对较小的孔径尺寸，扫描速度相对较慢。低分辨率扫描使用相对较大的光圈尺寸，扫描速度提高。快速扫描被限制在较低的采样率，这反过来允许相对于高采样率的更多的光学模糊。因此，通过允许在更大的孔径处放宽透镜像差规格，使最大孔径的增量成本最小化。优选地，例如通过使用电子控制的偏振板或通过使用电致变色物质来提供电子可变孔径。

摘要： Disclosed is an image reading apparatus in which the band width for reading by one scanning is variable in accordance with the original size, the reading mode, etc. R, G, and B image data of the k-th band is successively read in one-band width to store image data R1, G1, and B1 of pixel coordinates X(n, m). Then, the original is fed so as to cause partial overlapping of the (k+1)-th band with a lower predetermined pixel region of the k-th band, and R, G, and B image data of the (k+1)-th band is read in one-band width to successively store image data R2, G2, and B2 of pixel coordinates X(n, m′). The image data obtained through overlap reading of the k-th band and the (k+1)-th band is averaged to calculate correction image data, which is transferred to a host computer along with along other image data which has not been averaged as read image data. And, it is possible to optimize reading time according to the kind of original, reading mode, etc., without involving a deterioration in image quality.

摘要： In an image-forming method, a device reads line data L for one line and determines whether the resolution of the line data L in the main scanning direction is greater than or equal to a threshold th. If the resolution is greater than or equal to the threshold th, then a multiple line process is performed on the line data L to divide this data into two sets of partial line data L1 and L2. The partial line data 'L1 and L2 are used to form two lines at locations shifted from each other in the sub-scanning direction. However, if the resolution of the line data L is smaller than the threshold th, then a single line process is performed to divide the line data L into two segments Q1 and Q2. The segments Q1 and Q2 of the line data L are used to form a single line at the same location in the sub-scanning direction by printing the segment Q1 in the first main scanning operation and by printing the segment Q2 in the second main scanning operation.
