| 20080203149 | System and method for providing information - According to an aspect of an embodiment, a system comprises, a client for obtaining a code included in an image, and sending out the code obtained by the client and identification information of the client, and a server for obtaining address information on the basis of the code received from the client in association with the address information, identifying a table containing content address information, obtaining content address information on the basis of the code and the identification information in reference to the table, and providing the content address information to the client whereby the client is enable to obtain content information by using the content address information. | 08-28-2008 |
| 20080285846 | Image processing method, image zone detection method, image processing program, image zone detection program, image processing apparatus and image zone detection apparatus - An image processing method according to the present invention is contrived to change the gradation level (of the color component corresponding to the complementary color of yellow) for a pixel within a zone located on a corner of a rectangular image so as to maximize the difference between the gradation level of a pixel that is a processing target and the gradation level of a pixel in a background area in the surrounding area of the pixel that is the processing target, that is, lowering the gradation level. This means the pixel that is a result of applying the process for changing the gradation levels looks yellowish. The human eye has difficulty in recognizing yellow and therefore the change applied to the pixel is inconspicuous as compared to the case of placing a mark or frame on the outside of a rectangular zone. | 11-20-2008 |
| 20090066689 | Image displaying method - According to an aspect of an embodiment, a method for displaying an image including a plurality of blocks in which code information can be embedded, includes obtaining a first image including a plurality of blocks, obtaining a second image determined by changing the characteristic value of the selected blocks of the first image so as to associate the value with the code information to be embedded, and displaying the first image data and the second image data, sequentially. | 03-12-2009 |
| 20090110309 | IMAGE DECOMPRESSION APPARATUS, MEDIUM RECORDING IMAGE DECOMPRESSION PROGRAM, IMAGE DECOMPRESSION METHOD - An object of the present invention is to provide an image decompression apparatus, a medium recording an image decompression program, and an image decompression method capable of sequentially decompressing compressed data of a plurality of images. | 04-30-2009 |
| 20090123027 | Method of embedding informaton into image - According to an aspect of an embodiment, a method of embedding information into an image has obtaining an image data by taking the image by an image input device, dividing the image data into a plurality of blocks, determining an area in each of the blocks on the basis of a resolution power of the image input device, where a characteristic value may be modified in accordance with the information, respectively, comparing the size of the block with the size of the area and modifying a characteristic value of each of the blocks in accordance with the information to be embedded when the ratio of the size of the area with respect to the size of the blocks is smaller than a predetermined value. | 05-14-2009 |
| 20090196458 | METHOD, DEVICE, AND PROGRAM FOR EMBEDDING, DISPLAYING, AND RECOGNIZING DATA - First, the original data C is divided into an n number of pieces of partial data C | 08-06-2009 |
| 20090251597 | CONTENT CONVERSION DEVICE - A content conversion device includes a non-still picture data detecting unit which detects non-still picture data contained in a first electronic document that is an object to be processed, an embedded image generating unit which generates, in a data addition target image representing a frame contained in the non-still picture data or an image associated with the non-still picture data, embedded image data in which information about the non-still picture data is embedded, and an electronic document converting unit which creates a second electronic document in which the non-still picture data of the first electronic document is replaced with the embedded image data. | 10-08-2009 |

| 20080242371 | Mobile terminal device, communication system, electric power control method - A mobile terminal device has an electric-power-reduction operation mode for operation with reduced electric power consumption. The mobile terminal device includes an emergency determining unit that determines whether there is an emergency; and an operation mode control unit that controls to shift to the electric-power-reduction operation mode when the emergency determining unit determines that there is the emergency. | 10-02-2008 |
| 20100120395 | EMERGENCY CALL CODE INFORMATION ACQUIRING SYSTEM - A mobile communication base station transmits broadcast information containing emergency call code information to a mobile terminal with the status “Camped on any cell” defined in the 3GPP specification “TS25.304”. Upon receiving the broadcast information, the mobile terminal acquires emergency call code information from the broadcast information. The status “Camped on any cell” means that a status in which an IC card is uninserted and the mobile terminal is communicable with the mobile communication base station from the perspective of radio wave strength or a status in which an IC card is inserted, the mobile terminal is communicable with the mobile communication base station from the perspective of radio wave strength, and an Attach or location registration to an MSC via the mobile communication base station and an RNC fails. | 05-13-2010 |

| 20110010568 | Power supply apparatus and power supply control method - A main power supply and a backup power supply have the same set voltage. To prevent electrical power from being supplied from the backup power supply to a load circuit, during a normal operation, a power supply control unit gives a standby instruction to the backup power supply so that the backup power supply is on standby at a voltage lower than that of the main power supply. When an AC power supply is stopped, the backup power supply is operated at the set voltage and the main power supply is stopped. | 01-13-2011 |
