Abstract:
A first electronic file generated by reading an image is attached to a second electronic file having a security function. By executing the security function of the second electronic file to which the first electronic file has been attached, the security function is executed with respect to the first electronic file.
Abstract:
Provided is a screen display control device including: a compression unit which compresses image data; a rewritable video memory in which the data compressed by the compression unit of image data of one frame including line data (Y (Y: natural number) pixels/one line) of X (X: natural number) lines is written asynchronously with reading; an expansion unit which expands the compressed data which is periodically read from the video memory in synchronization with a frame period of a screen display, and restores original image data; a display unit which displays an image of the image data expanded and restored by the expansion unit; an input image data holding unit which holds input image data of one frame including line data (X pixels/one line) of Y lines by M (M: natural number, M
Abstract:
A cell phone is disclosed for acquiring information to be transmitted to a receiving facility and for transmitting such thereto. A capture device captures information from an external source. A processor is provided for associating with the captured information a representation of the date and time of the capture of the information, such that the representation of the date and time information in association with the captured information forms augmented captured information. The processing also places the augmented captured information in association with user information in a transmission of the augmented captured information to a receiving facility requiring such user information. A transmitter transmits the transmission including the augmented captured information and the user information to the receiving facility. An encryptor encrypts the augmented captured information for transmission to the receiving facility.
Abstract:
A method for enhancing security printing includes determining fields associated with print job variability. Physical security information is entered, and a physical security data stream is generated from the physical security information. The physical security data stream is mapped to a data stream that is used to provide settings for the fields for the print job variability. The fields for the print job variability are set based upon the mapping the physical security data stream.
Abstract:
Disclosed is an apparatus for processing image data in a portable terminal equipped with a camera. In the apparatus the image data photographed by the camera are coded by a predetermined coding scheme in a photographing mode of the camera, header information of a stream of the coded image data is generated and inserted into the stream, identifying information is generated as a watermark and the watermark is inserted into the stream, and the stream comprising the watermark is stored.
Abstract:
Disclosed is an image forming apparatus to form an image based on an XPS file including, a plurality of storage sections each of which has a different free storage space and a different access speed; and a control section to refer to information concerning usage frequency of each individual file stored in the XPS file to select the storage section to store the individual file subjected to a data decompression, to data-decompress the individual file, and to store the data-decompressed individual file in the selected storage section.
Abstract:
An apparatus for printing out recovered image data from a photograph is disclosed. The data is recorded in infrared ink on top of the image itself in an encoded fault tolerant digital form enabling the image to be recovered notwithstanding damage to the photograph surface. The apparatus can print out the image after processing the data. If the data is stored then the image can be printed as many times as required. Alternatively, the photograph can be repeatedly passed through the scanner or reader the required number of times. In another form of the invention, the apparatus can also print out the image with the image data again recorded in infra-red ink using a printer which has the necessary number of ink jet nozzles to do so and the apparatus has the necessary processing capacity to process, compress, scramble and encode the data.
Abstract:
A method for enhancing color fidelity in multi-reproduction, includes scanning an image to be reproduced, wherein the image contains an invisible digital watermark including color information; decoding the color information contained in the watermark; comparing the decoded color information with the scanned image; generating a correction table from the differences between the decoded color information and the scanned image; and performing color correction on the scanned image using the correction table. This method confines the color error to one generation, even when copies go through multiple reproduction.
Abstract:
Image, video, and/or audio data is encoded with at least first and second watermarks. In one implementation a method includes: receiving content; embedding a first watermark signal in the content; compressing the content; embedding a second watermark signal in the content. The first watermark signal and the second watermark signal are designed to respond differently to at least a first type of signal processing. Other implementations are also provided.
Abstract:
An electronic watermark data insertion apparatus comprises an insertion information memory (39) for preliminarily storing insertion information for designating electronic watermark data to be inserted block by block and an electronic watermark data insertion unit (33) for inserting, on the basis of the insertion information, the designated electronic watermark data from an electronic watermark data table (37) in a quantized image block by block. An electronic watermark data detection apparatus comprises an electronic watermark date extracting unit (45) for extracting the image data having a biased frequency region projecting in dependency on the inserted electronic watermark data block by block and an electronic watermark data detection unit (50) for calculating a statistical similarity between the extracted data and the electronic watermark data stored in an electronic watermark data table (48). An electronic watermark data accumulator (51) accumulates the statistical similarity for a predetermined time interval to produce an accumulated addition result which is reset after the elapse of the predetermined time interval or when the accumulated addition result exceeds the a predetermined threshold value. A determining unit (52) determines that the electronic watermark data is detected when the accumulated addition result exceeds the predetermined threshold value.
