    Abstract: PROBLEM TO BE SOLVED: To improve quality of an image to which an image effect is given by pixel value conversion processing using a correction factor. SOLUTION: Using correction value tables 2 -1 -2 -k having patterns varied according to the positional relationship of two pixels from which a difference value is calculated, a correction value is not decided simply according to the difference value but decided in compliance with both of the positional relationship between the pixels and the difference value between them, so that a proper correction value can be decided while selecting the positions of the pixels. In comparison with a conventional technology by which the correction value is simply changed for changing an emphasis degree, for example, quality of the image acquired by a pixel value conversion processing can be improved.

    Abstract: PROBLEM TO BE SOLVED: To prevent double encryption so that communication over a network will not slow down.
    SOLUTION: A double encryption preventing device is provided with a decryption processing section 103a, which determines whether the data inputted from a sender's terminal is encrypted. When the inputted data are encrypted, the decryption processing section 103a decrypts the inputted data and supplies the data to VPN routers 102A and 102B. When the inputted data have not been encrypted, the decryption processing section 103a supplies the inputted data to the VPN routers 102A and 102B without decrypting the data. Whether the data is encrypted by the sender's terminal which transmits the data, the decryption processing section 103a always supplies unencrypted plain text data to the VPN routers 102A and 102B so that the data will not be doubly encrypted, even if encryption is performed by the VPN routers 102A and 102B.
