摘要： A Two-Dimensional (2D) image segmentation apparatus for segmenting pixels of a progressive input 2D image includes a group information storing unit storing information of pixel groups including a plurality of adjacent pixels; a pixel determining unit determining coordinates of an input pixel, and determining whether the input pixel is an effective pixel for segmentation; a group scanning unit scanning a adjacent pixel group disposed in a scan range preset from the effective pixel in the group storing unit when the input pixel is determined as the effective pixel by the pixel determining unit; and a group information updating unit updating information of a pixel group stored in the group information storing unit according to whether there is the scanned adjacent pixel group and a pixel group including an input pixel preceding the effective pixel. Moreover, a method is provided that removes red-eye using area information of a pixel group determined by the segmentation apparatus.

摘要： Provided is a square root calculation apparatus. The apparatus includes a section judgment unit, a coefficient storing unit, and an adder. The section judgment unit stores information regarding a plurality of sections obtained by dividing an entire range of an input value into predetermined intervals, and judges one of the sections to which the input value belongs when the input value is input. The coefficient storing unit stores, in advance, first-order term coefficients and constant terms of first-order approximate equations obtained by approximating square root curves for respective sections, multiplies a first-order term coefficient of the first-order approximate equation in the section to which the input value belongs, by the input value to output a first-order term, and outputs a constant term in the section to which the input value belongs. The adder adds the first-order term and the constant term output from the coefficient storing unit to calculate an approximated square root value.
