    • An image processing device includes an in-plane pattern detector that selects a pixel of interest in a frame image of interest, calculates in-plane correlation index values representing correlations between the pixel of interest and in-plane pixel patterns including the pixel of interest, and selects a most highly correlated pattern as an in-plane addition pattern. A reference pattern detector calculates inter-plane correlation index values representing correlations between the in-plane pixel addition pattern and reference pixel patterns in a reference frame image temporally adjoining the frame of interest, and selects a most highly correlated reference pixel pattern. A pixel adder adds the values of the pixels in the selected in-plane pixel pattern and the selected reference pixel addition pattern to generate a corrected pixel value, thereby achieving high sensitivity and a high signal-to-noise ratio under low illumination, with little loss of resolution.

    • 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。

    • An electronic device that defends against an attack trying to identify confidential information from power consumption is provided without any circuit that performs a complementary operation to eliminate bias in power consumption. An elementary device A 100 is formed by a plurality of transistors 101-112. The elementary device A 100 receives inputs signals x1, x2, a random number r, and a control signal en, and outputs z. The output z is obtained by XORing (x1^r)&(x2^r) with the random number r. After the state transitions of the input signal, x1, x2, and the random number r, are settled, the control signal en is used to output z. This makes the signal transition rate of the output z equal, thereby defending against an attack trying to identify confidential information from power consumption.
    • 提供了一种电子设备,用于防止尝试从功率消耗中识别机密信息的攻击,而没有任何执行补充操作以消除功耗偏差的电路。 基本器件A 100由多个晶体管101-112形成。 基本设备A 100接收输入信号x1,x2,随机数r和控制信号en,并输出z。 通过用随机数r进行XORing(x1 ^ r)&(x2 ^ r)获得输出z。 在输入信号的状态转换x1,x2和随机数r之后,控制信号en用于输出z。 这使得输出z的信号转换速率相等,从而防止试图从功耗识别机密信息的攻击。
