Abstract:
The electronic camera has an imaging device that images a subject with subject reflectance R (%) with a dynamic range wider than that at displaying or printing to acquire image data and a recording device that converts the image data acquired by the imaging device with a predetermined function and records the converted image data and the information on the function as digital values (digit). Therefore, a printed image with an automatically or manually corrected density can be obtained at the displaying or the printing.
Abstract:
The present invention is related to providing, in association with an image, information related to the image capture device used to capture the image. In one embodiment, information related to a first static camera characteristic and camera setting information related to a first captured digitized image is embedded in the first captured digitized image using a watermark. The watermarked information may be used to identify the source or owner of the picture, and/or to aid in the more accurate reproduction of the image.
Abstract:
To provide a sign authentication system and method for authenticating the originality of an object having a sign such as a seal or a signature or a pattern which can be deemed as a sign, making counterfeit very difficult even if the mechanism of authentication is revealed, obviating the need for being additionally provided with a special device such as an IC chip used for authenticating the originality. A sign authentication system provides reading a sign such as a personal seal impression as color information for each mesh division, extracting feature points from the color information and storing them, and creating a code for authentication from the feature points. The sign is made with an ink containing color material particles smaller than the mesh division. The feature points on the basis of variation of color information caused are extracted when the mesh division is shifted.
Abstract:
An image processor which provides a color space conversion characteristic suitable for an image includes a transfer unit which transfers digital color image data representing a desired image input by an image input unit and having a color space depending on the image input unit, and extraction unit which extracts a color space conversion characteristic used to convert the color space depending on the image input unit into another color space. The transfer unit transfers the digital color image data having the color space depending on the image input unit and the color space conversion characteristic.

PROBLEM TO BE SOLVED: To provide a sign authentication system and sign authentication method for authenticating the originality of an object having a sign such as a seal or a signature which is deemed as a sign, making counterfeit very difficult even if the mechanism of authentication is revealed, and obviating the need for being additionally provided with a special device such as an IC chip used for authenticating the originality. SOLUTION: The sign authentication system includes reading means for reading a sign such as a seal as color information by mesh division, feature point extracting means for extracting feature points from the color information and storing them, and code creating means for creating a code for authentication from the feature points. The sign is made with an ink containing color material particles smaller than the mesh division. The feature point extracting means is determined on the basis of variation of color information caused when the mesh division is shifted. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PURPOSE: An information processing unit and an information processing method for judging alteration of image data are provided to surely guarantee the original image pixel data interpolating raw image data. CONSTITUTION: An input unit(111) inputs the verification data of the first pixel group and image data. The image data comprises the first pixel group and the second pixel group by interpolating the first pixel group. The first verification unit uses the first pixel group and validation data. The alteration of the first pixel group verifies an inspection of evidence. The second verification unit determines the relation of the first pixel group and the second pixel group. A decision unit judges the alteration of image data based on the inspection result of the first and the second verification unit.
