Abstract: In the case of combining images subjected to lighting from a plurality of directions, a manual control such as light quantity control is needed and is therefore troublesome. The present invention includes an input unit receiving a first image obtained by shooting a subject with light applied thereto from a first lighting device in a diagonal direction, the input unit receiving a second image obtained by shooting the subject with light applied thereto from a second lighting device in an opposite diagonal direction, the input unit accepting information on the subject and a shooting device; a blend pattern generating unit calculating and finding, based on the accepted information, a ratio Z for determining a proportion in combining of the first image and the second image for each pixel; an image blending unit obtaining a third image combined by adding the first image multiplied by the ratio Z and the second image multiplied by 1?Z for each pixel; and an output unit outputting the third image.

Abstract: An object of the present invention is to achieve segmented image taking and merging processing of segmented images with logical consistency with high efficiency at low cost and thereby to enable easy formation of a high-definition merged image.

Abstract: The coordinate system of the electronic data 112 to be projected on the touch panel 120, and the coordinate system of the two-dimensional object 130 similar to the electronic data pasted, printed etc. on the touch panel 120 to which the electronic data is to be projected, are associated by an alignment instruction from a user to the touch panel to specify the position of electronic data corresponding to the specified position indicated to the touch panel and to specify related data linked to the specified position. Outputting this related data is also an aspect of the present invention. Further, outputting this output to an output device different from the touch panel and displaying and the like with this output device is also an aspect of the present invention.

Abstract: An image processing method for automatically executing operation steps of repairing a defect of an image of a document which is read by a scanner and changing a background image in a short time and a recording medium for storing them. An image processing method comprising a step of separating background image data from said image data by processing by a maximum filter for comparing the brightness of each pixel constituting said image data with the brightness of peripheral pixels and replacing it with the maximum brightness; and a step of separating character and figure image data by subtracting the background image data obtained by the above step in (a) from the above image data.

Abstract: An image file for recording natural images, a generation method of the image file and an image display apparatus for displaying image data from this image file. The image file includes image data obtained by digitizing an original, and conversion tables for separating the color tones of the original into R, G and B and converting the changes of the color tones to input luminance-v-output luminance. The image display apparatus controls a color look-up table by the conversion tables read out from the image file, and displays the image data read out from the image file.
