| 20090002526 | Image processing device, image processing method, and image processing program - An image processing device that performs color shading correction on an image formed by a plurality of pixel signals with correction data includes: a correction execution decision unit that decides whether or not color shading correction is to be executed for each pixel signal in order to perform color shading correction for a part of the plurality of pixel signals and not to perform color shading correction for another part of the plurality of pixel signals; and a correction unit that performs correction of the pixel signal of which execution of correction is decided by the correction execution decision unit for each color component thereof. | 01-01-2009 |
| 20090010535 | Image Processing Device, Image Processing Program, and Image Processing Method - An image processing device that transforms first image data of an image captured under an image-capturing condition into second image data that reproduce a color appearance under a viewing condition, includes: an image data acquiring unit that acquires the first image data of the image captured under the image-capturing condition; a first transformation unit that transforms the acquired first image data into the second image data pixel by pixel based on the image-capturing condition and the viewing condition by a first method that takes into consideration chromatic adaptation; a second transformation unit that transforms the acquired first image data into the second image data pixel by pixel based on the image-capturing condition and the viewing condition by a second method that is simpler than the first method and takes into consideration chromatic adaptation; and a controlling unit that controls such that either the first transformation unit or the second transformation unit is selected depending on a state of a transformation target pixel or a neighborhood pixel neighboring the transformation target pixel in the first image data. | 01-08-2009 |
| 20090195670 | Image processing device, image processing method and program product - An image processing device that reproduces under a second observation condition an appearance of a color of a subject as perceived under a first observation condition, includes: a characteristic quantity calculation unit that calculates a characteristic quantity related to a state of visual perception adaptation under an observation condition that is at least one observation condition of the first observation condition and the second observation condition, by taking into consideration information related to an illuminating light source used under another observation condition in addition to information related to an illuminating light source used under the one observation condition; and a color conversion unit that executes color conversion to convert the first image data to second image data to be used to reproduce, under the second observation condition, the appearance of the color of the subject as perceived under the first observation condition, based upon the characteristic quantity having been calculated. | 08-06-2009 |
| 20100026837 | IMAGE PROCESSING METHOD, IMAGE PROCESSING PROGRAM, IMAGE PROCESSING DEVICE AND CAMERA - An image processing method for executing color conversion processing on input image data by taking into consideration chromatic adaptation so as to match a color appearance perceived under a first viewing condition and a color appearance perceived under a second viewing condition, includes: executing the color conversion processing by setting in correspondence to each of parameters representing colors, at least one of an adaptation factor indicating an extent of adaptation to the first viewing condition and an adaptation factor indicating an extent of adaptation to the second viewing condition. | 02-04-2010 |
| 20100134643 | IMAGE PROCESSING METHOD, IMAGE PROCESSING PROGRAM, IMAGE PROCESSING DEVICE, IMAGE PROCESSING SYSTEM, ELECTRONIC CAMERA AND ELECTRONIC APPARATUS - An electronic apparatus includes: a projection unit that projects a projection-target original image onto a projection surface; an imaging unit that captures an image of the projection surface onto which an image is projected by the projection unit; and a control unit that analyzes the photographic image of the projection surface captured by the imaging unit and adjusts a correction quantity representing an extent to which the projection-target original image is to be corrected based upon analysis results. | 06-03-2010 |
| 20100165137 | IMAGE PROCESSING METHOD, IMAGE PROCESSING PROGRAM, IMAGE PROCESSING DEVICE AND CAMERA - An image processing method for executing color conversion processing on input image data by taking into consideration chromatic adaptation, includes: executing color conversion processing by taking into consideration an adaptation factor indicating an extent of adaptation to an illumination condition under which a scene where an input image is obtained is illuminated or an adaptation factor indicating an extent of adaptation to a viewing condition where the input image is observed; and altering the adaptation factor in correspondence to a color of a conversion target pixel. | 07-01-2010 |
| 20110001843 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND ELECTRONIC CAMERA - An image processing apparatus comprising: an input visual environment acquisition unit that acquires a shooting scene viewing condition at the time of shooting an image, an output visual environment acquisition unit that acquires a shot image viewing condition, a converting unit that converts the image using a predetermined color appearance model based on the shooting scene viewing condition acquired by the input visual environment acquisition unit and the shot image viewing condition acquired by the output visual environment acquisition unit, and a correction unit that corrects a parameter of the color appearance model used by the converting unit by using at least one of a shooting condition of the image and a scene judging result based on at least one of the image and the shooting conditions of the image. | 01-06-2011 |
| 20110018897 | PROJECTOR - A projector includes: an image forming unit that forms a projection image; a detection unit that detects a condition at a projection surface onto which the projection image is projected; a correction unit that corrects a source image based upon the condition at the projection surface to obtain the projection image; and a projection unit that projects the projection image. | 01-27-2011 |
