20080309789 | Output image adjustment of image data - Using image data generated by an image generating device, and image generation record information that is associated with the image data and that includes at least subject area information indicating a subject area in the image, hue of each pixel in the subject area is calculated, and in the event that the proportion of pixels having hue of a predetermined color range is greater than a first predetermined threshold value, an image quality adjustment process appropriate for an image containing a subject identified by the predetermined color range is executed. In preferred practice, the predetermined color range is the skin color range, and the image quality adjustment process is a process appropriate for a portrait image. When the image quality adjustment process appropriate for a portrait image is not executed, and in the event that the proportion of pixels having hue in the green range is greater than a second predetermined threshold value or in the event that the proportion of pixels having hue in the sky blue range is greater than a third predetermined threshold value, an image quality adjustment process appropriate for a landscape image is executed. | 12-18-2008 |
20090103806 | Adjustment for output image of image data - When a memory card is inserted into a slot, the control circuit of a color printer obtains image output control information from a memory card and analyzes it. When auto light source is not set as the light source, the CPU references the reference values and coefficients for the characteristics parameters except for color balance and performs correction, and then adjusts the image data image quality to reflect the post-correction characteristics parameters. As a result, it is possible to automatically adjust the image quality of image data without losing the selectively set output conditions. | 04-23-2009 |
20090128840 | Apparatus, method, signal and computer program product configured to provide output image adjustment of an image file - An apparatus, method, signal and computer program product is provided to generate an image file that can correctly reproduce image data at a predetermined output device. The image file includes an image data storage area that stores image data, and a control information storage area stores output control information. The image data is stored in JPEG format for example, and output control information is stored in TIFF format. The output device control information is information set so as to be able to obtain an optimal image output results according to a paired-combination of the input device and output device, taking into consideration their respective image processing characteristics. | 05-21-2009 |
20090167872 | Adjustment for output image of image data - An image processing method of processing an image data uses an image file. The image file includes the image data and image processing control information being used for processing the image data. The method includes the steps of: (a) determining a degree of auto adjustment for adjusting lightness and contrast of the image data according to lightness of a whole image expressed by the image data, based on the image processing control information; and (b) performing the auto adjustment based on the determination. | 07-02-2009 |
20090262983 | Image processing based on object information - A CPU divides an image into plural regions and for each of the regions, generates a histogram and calculates an average brightness Y ave. The CPU determines a focus location on the image by using focus location information, sets a region at the determined location as an emphasis region, and sets the average brightness Y ave of the emphasis region as a brightness criterion Y std. The CPU uses the brightness criterion Y std to determine non-usable regions. By using the regions not excluded as non-usable regions, the CPU calculates an image quality adjustment average brightness Y′ ave, i.e. the average brightness of the entire image, with a weighting W in accordance with the locations of the regions reflected thereto, and executes a bright value correction by using the calculated image quality adjustment average brightness Y′ ave. | 10-22-2009 |

The apparatus comprises an automatic picture quality adjuster configured to automatically regulate lightness of the image data according to lightness of a whole image expressed by the image data and an adjustment degree determiner configured to determine a degree of the auto adjustment based on the image processing control information. | 04-08-2010 |
20100265359 | Output image adjustment of image data - A CPU calculates modified brightness correction amount tCurve_Y with consideration of exposure correction amount (or exposure value) EV if photography information PI (or Exif IFD) is included in image data GF.

20110150360 | ADJUSTMENT FOR OUTPUT IMAGE OF IMAGE DATA - If a memory card is inserted in a slot, a control circuit of a color printer acquires image output control information from the memory card and analyzes this information. A CPU modifies a brightness standard value Bstd corresponding to a brightness parameter by taking account of a preset exposure bias value when an exposure bias value other than zero is set. The CPU determines the brightness correction level Brev by correcting the brightness representative value Brep so as to bring it closer to the brightness standard value Bstd that has been modified, and adjusts the image quality of image data by taking account of the brightness correction level Brev. As a result, the image quality of image data can be automatically adjusted without degrading output conditions that have been set arbitrarily. | 06-23-2011 |

20120229871 | Image Processing Apparatus, an Image Processing Method, A Medium on Which an Image Processing Control Program is Recorded, an Image Evaluation Device, an Image Evaluation Method and a Medium on Which an Image Evaluation Program is Recorded - A method for image processing image data having a plurality of picture elements. While scanning the image data, a scanned picture element is determined to be sampled or not according to a plurality of sampling methods until the scanned picture element is displaced to a next picture element (to be scanned) of the image data. | 09-13-2012 |
20130121596 | IMAGE PROCESSING APPARATUS, AN IMAGE PROCESSING METHOD, A MEDIUM ON WHICH AN IMAGE PROCESSING CONTROL PROGRAM IS RECORDED, AN IMAGE EVALUATION DEVICE, AN IMAGE EVALUATION METHOD AND A MEDIUM ON WHICH AN IMAGE EVALUATION PROGRAM IS RECORDED - A computer calculates an edginess, which is an image variation from a differential value of data for adjacent picture elements, and determines object picture elements by selecting only images with a large variation. As optimum parameters for contrast correction and lightness compensation are calculated from image data for object picture elements, image processing indicators based on object picture elements are determined, and optimum imago processing can be performed automatically. After summing a luminance Distribution for each area of the image, which is a feature amount, while uniformly selecting picture elements, a reevaluation is performed by a weighting determined for each area, and a luminance distribution, strongly influenced by the luminance distribution of the photographed object is thus obtained with uniform sampling. After determining the intensity of this luminance distribution, the image data is converted, and image processing can therefore be performed with optimum intensity while reducing the processing amount. | 05-16-2013 |
