Abstract:
An image processing apparatus comprises an image processing unit configured to execute image processing which involves a change in a boundary shape of image data; a face detection unit configured to detect a face region included in the image data; a setting unit configured to set a parameter of the image processing; and a determination unit configured to determine whether or not to execute the image processing or whether or not to output a warning in accordance with the parameter of the image processing set by the setting unit and a position of the face region detected by the face detection unit.
Abstract:
This invention makes it possible to obtain an enlarged image while suppressing noise and maintaining the sharpness of an original image only by setting a simple enlargement ratio without no special knowledge. Original image data (Ia) is enlarged in accordance with a set enlargement ratio (E) to generate an enlarged image (IA). The enlarged image (IA) is smoothed by using a smoothing filter with a size depending on the enlargement ratio (E) to generate smoothed image data (IB). Difference image data (IC) is generated by calculating the difference between the enlarged image data (IA) and the smoothed image data (IB). The generated difference image data is multiplied by an emphasis coefficient. The product is added to the enlarged image data, thereby obtaining image data (IS) that has undergone enlargement/unsharp masking.
Abstract:
An image processing apparatus corrects a shot image which is captured by an image capturing apparatus including an image sensor having a plurality of pixels arrayed two-dimensionally and on which a shadow of a foreign substance adhering to an optical element placed in front of the image sensor is captured. This apparatus includes an interpolation unit which performs interpolation processing of interpolating a signal of a pixel corresponding to the shadow of the foreign substance with a signal of a neighboring pixel, a designation unit which inputs an instruction to cause the interpolation unit to perform the interpolation processing, and a control unit which causes the interpolation unit to perform the interpolation processing, and when the interpolation unit has not performed the interpolation processing, causes the interpolation unit to re-execute the interpolation processing upon changing a parameter for the interpolation processing or an algorithm for the interpolation processing.
Abstract:
To generating a mosaic image by combining a plurality of material images, an original image is divided into tiles and a material image having a characteristic similar to that of an image in each tile is applied to the tile. If more than one version of image data having different resolutions is provided as the image data for the material image, a low-resolution version of the image data is used to calculate a characteristic quantity of the image. Thus, the amount of time required to generate the mosaic image can be reduced.

Abstract:
Binary data to which meta-data is to be appended, and meta-data to be appended to the binary data are loaded. The meta-data has an XML format. The loaded meta-data is connected after the loaded binary data. The data synthesized in this manner is output as a single file as a whole. In this file data, since header information remains the same as that before connection of the meta-data, binary data can be reproduced by an existing browser or the like. A binary file with meta-data can be discriminated by checking if data in a correct XML format is present at the end of data.
Abstract:
In conventional technique, a layout result is displayed on only one page, and a print result cannot be roughly observed by reduced display of all pages. For this reason, a specific image printed on a specific page cannot be overlooked, and a user must print the image while imaging an image result. When a user tries to change a layout method in the middle of a printing operation, the user must inconveniently restart the operation. In order to solve the problem, a printing apparatus for printing an image selected from images stored in a storage medium includes an image display unit for displaying the image in the storage medium as a list, a printing object selection unit for selecting an image to be printed with reference to the image display unit, a print medium selection unit for selecting medium on which the image is printed, and a print layout selection unit for selecting an arbitrary layout from layouts depending on the medium selected by the print medium selection unit.
Abstract:
An image as a basis of a mosaic image is segmented into M×N areas by the process shown in FIG. 4 (S300), and the image characteristics of the segmented areas (S301), and those of source images (S305) are obtained. When the source image is a moving image, the image characteristics of that moving image are obtained from those of a plurality of still images in the moving image (S304). Source images corresponding to the segmented areas are determined (S309) and pasted (S310), thus generating a mosaic image.
Abstract:
In the retrieval of images that resemble a target image from a plurality of images, the image feature quantity of the target image is calculated when the target image is specified. The feature quantity is calculated upon removing an unnecessary area from the specified target image, and retrieval of resembling images is performed using the feature quantity that has been calculated. The unnecessary area is determined automatically based upon a change in luminance in directions vertically and horizontally of the periphery of the target image. Thus, the calculation of feature quantities from which unnecessary portions in an image have been eliminated can be executed with ease and more effective retrieval of resembling images can be carried out.
Abstract:
There are provided an image processing method and apparatus for generating a mosaic image by combining a plurality of material images in a mosaic pattern. The number of material images is increased on the basis of a plurality of stored material images, material images added by capturing a moving image, or the like, and a mosaic image with higher image quality is generated based on such material images.
