Abstract: If a non-edge part of an image is thinned at a constant thinning ratio regardless of an image size (a character size or a line image width), a reduction in image density in the non-edge part becomes more conspicuous with increasing image size, which can lead to a reduction in image quality.

The thinning ratio is set to be smaller for images with sizes greater than or equal to a predetermined value than for images with sizes smaller than the predetermined value such that a high-quality image with sufficiently high density in its non-edge part is obtained regardless of the image size.

Abstract: A mechanism for providing edge enhancement or attenuation in a vector error diffusion process includes warping a marking decision color space as a function of at least one pixel value of a target pixel. The warping changes the membership of sets of error modified pixel values associated particular sets of marking. The warping is controlled by a function of pixel values of a target pixel from an input image. Therefore, the warping is constant for uniform portions of the image. Since pixel values change at edges or where colors change, a mechanism is provided for the presence of edges to influence the vector error diffusion process. Selection of the function by which the marking decision color space is warped provides a means for controlling the aggressiveness of the edge enhancement or attenuation. Equivalent processing includes warping or adjusting error modified pixel values according to corresponding functions.

Abstract: A laser beam is periodically deflected before being directed into a sample volume. The beam is deflected at a frequency such that the beam makes one or more passes through the sample volume while data are collected from the sample volume. The amplitude of motion of the beam, the dwell time of the beam at any given point, and the Gaussian intensity profile of the beam cooperate to produce an effective flat topped illumination profile for the light that is incident on specimens in the sample volume. The total photon exposure at any given point in the sample volume is a function of both the beam intensity and the dwell time at that location. Therefore, a longer dwell time and lower intensity at the edge of the profile are in balance with a shorter dwell time and higher intensity at the center of the profile.
