    • Disclosed is an information distribution system in which a receiving terminal installed in a mobile object can reliably receive high quality distribution information from the beginning. The information distribution system comprises data transmission units, each for transmitting a plurality of data signals including same distribution information using a plurality of different radio channels with sequentially delaying the transmission start time of the data signals; an auxiliary transmission unit for transmitting signals according to communication status of the data transmission units; a communication control unit for controlling the auxiliary transmission unit and the data transmission units; and detection means for detecting the velocity control information for the mobile object. A receiving terminal for receiving the data signals transmitted from the data transmission units is installed on the mobile object. The communication control unit selects a data transmission unit in a communication status according to the velocity control information out of the data transmission units, and controls the auxiliary transmission unit so as to notify the receiving terminal of the communication information corresponding thereto.

    • Inspection data 30 can be inspected by comparing reference data and the decrypted inspection data 30 (ST304) and, for example, after the inspection, individual data are encrypted according to their respective levels of secrecy (ST306) and are stored in flash ROMs 5, 6 and 7 (ST306), so that data of high level of secrecy can be prevented from being leaked out and data can be efficiently protected and stored. In addition, there is a case where when the protection level increases, the processing speed required for encryption increases, causing an increase in cost, but since the inspection data 30 is encrypted and stored according to its level of secrecy (ST305), cost reduction can be promoted compared to the case where all data are set to protection level 3. Accordingly, it is possible to provide a data inspection apparatus, a data inspection method and a data inspection program all of which are capable of preventing leak of information.
    • 可以通过比较参考数据和解密的检查数据30(ST304)并且例如在检查之后,根据各自的保密级别(ST306)对各个数据进行加密来检查检查数据30,并存储在闪存ROM中 5,6和7(ST306),从而可以防止高密度的数据泄漏出来,并且可以有效地保护和存储数据。 此外,存在如下情况:当保护等级增加时,加密所需的处理速度增加,导致成本增加,但是由于检查数据30根据其保密级别被加密和存储(ST305),所以成本 与将所有数据设置为保护等级3的情况相比,可以促进减少。因此,可以提供能够防止信息泄漏的数据检查装置,数据检查方法和数据检查程序。

    • An ink-jet recording method which hardly causes ink to blur. To this end, there are provided a correction table (30) which contains the number of ejection ink dots of each color limited in advance according to the combination of the numbers of ejection ink dots instructed for respective colors in a unit area in such a way that the total number of ejection ink dots does not exceed a predetermined limit value, and an error table (31) which contains the errors which may be produced when determining the limited numbers of ejection ink dots of the colors and which are previously calculated and determined according to the combination of the numbers of ejection ink dots instructed for the colors in the unit area. Before printing, a corrected number of ejection ink dots for each color in each unit area is determined from the correction table (30) according to the combination of the numbers of ejection ink dots on which each head is instructed based on binary image data (S25). At this time, the errors listed in the error table (31) are accumulated for every unit area (S27), the integer part, if appears in the accumulated value, is made to affect the numbers of ejection ink dots, and the accumulated error is updated (S25).

    • A method is provided for transmitting and receiving image data having plural pixel data. The method comprises the step of producing image control data for controlling the image data to be transmitted. The plural pixel data is represented by n color components, and pixel data represented by n+m color components is produced for sequential transmission on the basis of the pixel data represented by the n color components. The image control data are transmitted for a period of time when the pixel data represented by the n color components are not provided in the period of time when pixel represented by n+m color components are transmitted. An image process is executed for either the pixel data represented by the n color components or the pixel data represented by the n+m color components on the basis of the image control data.
