    • A searchable encryption resistant to frequency analysis. A conversion rule management device generates a conversion rule table associating a search keyword with a conversion keyword group. Based on the conversion rule table, a data registration device generates registration data associating encrypted data with an encrypted keyword, and registers the registration data in a server device. An information processing device obtains from the conversion rule table a conversion keyword group associated with a specified search keyword, generates an encrypted keyword group, and requests a data search by specifying the encrypted keyword group. Using as a search key an encrypted keyword included in the encrypted keyword group, the server device searches for encrypted data associated with the search key, and returns searched encrypted data. The information processing device decrypts the searched encrypted data, and outputs as a search result search data obtained by decryption.
    • 可搜索的加密功能可抵抗频率分析。 转换规则管理装置生成将搜索关键字与转换关键字组关联的转换规则表。 基于转换规则表,数据登记装置生成将加密数据与加密关键词相关联的登记数据,并将注册数据登记在服务器装置中。 信息处理装置从转换规则表获得与指定搜索关键字相关联的转换关键字组,生成加密关键字组,并通过指定加密的关键字组来请求数据搜索。 使用包括在加密关键字组中的加密关键字作为搜索关键字,服务器设备搜索与搜索关键字相关联的加密数据,并返回搜索到的加密数据。 信息处理装置对所搜索的加密数据进行解密,并输出作为通过解密得到的搜索结果的搜索结果。

    • For each pixel in an image (Din), a contrast correlation value (CT) is detected for peripheral areas centered around the pixel to be corrected (1), a contrast enhancement coefficient (Ken) is determined in accordance with the contrast correlation value (CT) (2), and in accordance with the enhancement coefficient (Ken), local contrast is enhanced for each pixel and an intermediate image (D3) is generated (3). When performing noise reduction (5) by smoothing the intermediate image (D3) in the time direction, the degree of noise reduction is controlled in accordance with a noise reduction coefficient (Knr) that is large where the enhancement coefficient (Ken) is large. With respect to a low-contrast image such as one captured under fog, haze or other poor weather conditions, the contrast in areas having reduced contrast is appropriately improved, and the noise that is enhanced in conjunction with contrast improvement is reduced, enabling a high quality image to be obtained.
    • 对于图像(Din)中的每个像素,以围绕待校正像素(1)为中心的周边区域检测对比度相关值(CT),根据对比度相关值( CT)(2),并且根据增强系数(Ken),对于每个像素增强局部对比度,并且生成中间图像(D3)(3)。 当通过在时间方向上平滑中间图像(D3)来执行降噪(5)时,根据增强系数(Ken)大的噪声降低系数(Knr)来控制噪声降低的程度。 对于诸如在雾,雾或其他差的天气条件下捕获的低对比度图像,适当地改善了对比度降低的区域中的对比度,并且降低了与对比度改善相结合的噪声,使得能够高 要获得质量图像。
