摘要:
An image reading apparatus is attached to the top of a PDA. During the image reading operation, an operation state control signal is output from the image reading apparatus to the PDA. According to the signal, the intensity of an input display unit not required during the operation can be reduced. Additionally, the power supply or the supply of a signal not required during the operation is stopped. Furthermore, an LED of the PDA issues a notification of an operation state by lighting, blinking, or turning-off. When the input display unit displays an image, an erect image and an inverted image are appropriately switched depending on the operation state. During an image reading operation, input by input buttons and a touch panel of the input display unit are nullified to avoid the occurrence of a malfunction.

In an image authentication system, a printing unit prepares a code in a form of an image of a different density in any two adjacent blocks, and prints the code onto a recording medium as a printed image. A storage unit stores therein image data corresponding to printed images and codes to be embedded in image data corresponding to the printed images in a correlated manner. An authenticating unit receives scanned image data corresponding to a printed image, extracts a code embedded in the scanned image data and authenticates the printed image corresponding to the scanned image data based on extracted code.

Image identifier information specific to image data to be input to an image search apparatus is embedded in the image data as a steganography in advance. Meanwhile, the side of an image search apparatus decodes the steganography contained in image data, detects the image identifier information, compares the detected image identifier information with an externally instructed search condition and outputs image data if the aforementioned two kinds of information are identical.

A first encoder splits an image into a plurality of blocks, and embeds a first data into the image based on a difference between feature amounts in a combination of the blocks. A second encoder encodes a second data in a form of a combination of image patterns. A disposing unit disposes the combination of image patterns in the image in which the data is embedded by the first encoder.

An apparatus that embeds data in an image includes a mark embedding unit that embeds a feature that forms a predetermined pattern in the image, as a mark to be used to specify an area in which the data is embedded, and a data embedding unit that embeds the data in the image of the area specified by the mark.
摘要:
A bar code is scanned and a line of image data is extracted in a process. The line of extracted image is divided into patterns forming characters in a process. The divided patterns are converted into characters in a process. In the process, a pattern is divided by the number of modules having the smallest width forming a black bar or a white bar, a module value indicating each module as black or white is determined, and each pattern is converted into a character, thereby correctly recognizing a bar code using general-purpose optical equipment for reading a bar code.
摘要:
An image reading apparatus including an image reading section, an amount-of-movement detecting thinning out the transfer data other than particular transfer data, each of successive transfer data pieces at a time, adding the amount of movement, which is contained in the thinned-out transfer data, to the amount of movement, which is contained in the particular transfer data, and generating compressed data composed of the image data in the particular transfer data and the added amount of movement, and a data transferring section for transferring one of the transfer data and the compressed data to a destination. With such image reading apparatus, not only the image is reproduced free from shortage in size in the direction of scanning regardless of the speed of scanning, not only it is possible to reduce an amount of data to be transferred to the destination from the image reading apparatus.

An image reader, detachably attached to an electronic apparatus, which scans and reads an image formed on a surface to be read includes an image reading part that reads the image; and a scan amount detection part that detects a scan amount by the image reading part, the scan amount detection part including a scaler that is arranged oblique to a vertical scanning direction orthogonal to a horizontal scanning direction, and moves along with scanning by the image reading part.
摘要:
One document image is divided according to attributes such as a character, a graphic, a table, etc., and the divided partial images are stored as one file. For example, each of the partial images is stored by being assigned with a priority, reduced in stages, and compressed with a compression method suitable for each of the attributes. If a user, etc. issues the instruction for making more of a desired portion visible and easy to view when he or she displays the document image, the user can freely make an easy-to-view display that the user desires according to the contents of the instruction. For example, the document image can be displayed by making an empty space between partial images smaller, a partial image with a higher priority can be displayed earlier, a specified partial image can be displayed larger, etc.
