20150313466 | OPTICAL IMAGE MEASURING APPARATUS, IMAGE DISPLAYING APPARATUS AND IMAGE DISPLAYING METHOD - An optical system splits light into signal light and reference light and detects interference light between scattered light of signal light from living body and reference light. A scanner performs first scan in which first cross section that intersects interested blood vessel is repeatedly scanned with signal light. An image forming part forms first cross sectional image expressing chronological variation of morphology of first cross section and phase image expressing chronological variation of phase difference based on detection results of interference light acquired during first scan. A blood vessel region specifying part specifies blood vessel region corresponding to interested blood vessel for first cross sectional image and phase image. A blood flow information generator generates blood flow information related to interested blood vessel based on blood vessel region of first cross sectional image and chronological variation of phase difference within blood vessel region of phase image. | 11-05-2015 |
20150093046 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND STORAGE MEDIUM - An image processing unit of an image processing apparatus includes: a pixel value acquiring part that acquires pixel values of new pixels obtained by increasing resolution of a first image, using pixel values of multiple original pixels, of the first image, around a position at which each of the new pixels is disposed; a representative value acquiring part that acquires a representative value of the pixel values of the multiple new pixels arranged in an area in which each of the original pixels is disposed; a correction value acquiring part that acquires a correction value using the pixel value of each of the original pixels and the representative value; and a pixel value correcting part that corrects the pixel value of each of the original pixels using the correction value. The image processing unit performs correction processing for correcting the original pixels is repeated once or at least twice. | 04-02-2015 |
20140321727 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD AND STORAGE MEDIUM - An image processing apparatus includes: a region-of-interest setting information storage unit in which region-of-interest setting information for setting one or more regions of interest in a specified cross-sectional image is stored; an evaluation value acquiring unit that acquires, using measured values, an evaluation value for evaluating a region of interest in the specified cross-sectional image, for each region of interest indicated by the region-of-interest setting information, and acquires, using measured values, a related evaluation value for evaluating a region in one or more cross-sectional images other than the specified cross-sectional image, for each region corresponding to each region of interest indicated by the region-of-interest setting information; and an output unit that outputs the acquired evaluation value and related evaluation value in association with the specified cross-sectional image corresponding to the evaluation value and the cross-sectional image corresponding to the related evaluation value. | 10-30-2014 |
