    摘要: In a zoom lens consisting of a first lens group having a negative refractive power and a second lens group having a positive refractive power with the air separation between the first and second groups being variable for zooming, there are provided two non-spherical surfaces positioned respectively in the first lens group and on the image side of a diaphragm in the second lens group at optional locations to prevent deterioration of aberrations which occurs when the image angle of the zoom lens is increased.

    摘要: In a variable focus objective an axial air space between a negative front lens and a positive rear lens component is variable for zooming. The first component is movable for focusing independently of the rear component and provided with a variable air space defined therein to facilitate focusing down to short object distances while preserving high grade imagery for close objects throughout the zooming range and assuring a good uniformity of image quality throughout the entire image region even at the full open aperture.

    摘要: A zoom lens system comprising from front to rear a first lens group of negative power and a second lens group of positive power with the axial separation therebetween being variable for zooming purposes. The first lens group is provided with a non-spherical surface to achieve minimization of the overall dimensions of the complete system without causing any decrease in the extent to which the corrections of various aberrations are maintained throughout the zooming range irrespective of a great increase in the photographable range extended toward the wide angle side.

    摘要: A quantizing unit, error detector, error diffusion matrix, and adder quantize a pixel of interest of an input image by an error diffusion method. A calculation unit and gain adjuster calculate a value to be added to the pixel of interest with reference to quantized pixels. The adder adds the calculated value to the pixel of interest. A control unit controls the calculation of the gain adjuster.

    摘要: A halftone screen which is applicable to a low-resolution electrophotographic printer is created. Hence, dot-lattice points arranged in a predetermined region are displaced using rotation processing, the predetermined region is partitioned into polygons each of which surrounds the dot-lattice point. Then, a threshold matrix used to grow a halftone dot, which is surrounded by each polygon, in a direction of the displacement is generated.

    摘要: A porous foam based ink containment system is provided with grooves defined in the exterior portion thereof, for storing ink, while preventing ink leakage from the ink-jet pen. The grooves provide passageways to allow air diffused throughout the ink and trapped air bubbles within the foam to expand and move to the atmosphere. An atmospheric vent is in fluid communication with at least one of the grooves.
