    • An element determining unit detects an element that should be excluded from an object of comparison, of an image. Using the image with the detected element removed, comparing process is performed. Specifically, a feature value calculating unit calculates, in correspondence to each of a plurality of partial images in the image, a feature value in accordance with a pattern of the corresponding portion. The element determining unit detects an area represented by a combination of partial images having a prescribed calculated feature value, as the element to be excluded from the object of comparison. Based on the ratio of the detected elements as non-eligible for comparison to the image as a whole and on the result of comparison, activation of an application is permitted/inhibited.
    • 元素确定单元检测图像中应当从比较对象中排除的元素。 使用删除检测到的元素的图像,执行比较处理。 具体地,特征值计算单元对应于图像中的多个部分图像中的每一个,根据对应部分的图案来计算特征值。 元素确定单元检测由具有规定的计算特征值的部分图像的组合表示的区域作为要从比较对象中排除的元素。 基于检测到的元素与图像整体不符合比例的比例,并且比较结果允许/禁止应用的激活。

    • A sensing device includes first sensor elements allocated on a two-dimensional plane, and a second sensor element allocated on the same plane as the first sensor element and operating according to a manner different from that of the first sensor element. A signal processing unit generates a fingerprint image based on an output signal of the first sensor element after detecting placement of a finger based on an output signal of the second sensor element, and collates the generated fingerprint image with a previously registered fingerprint image. A capacitance type sensor element is used as the first sensor element, and a pressure sensitive sensor element is used as the second sensor element.
    • 感测装置包括分配在二维平面上的第一传感器元件和分配在与第一传感器元件相同的平面上的第二传感器元件,并且根据与第一传感器元件不同的方式进行操作。 信号处理单元基于第二传感器元件的输出信号检测到手指的位置后,基于第一传感器元件的输出信号生成指纹图像,并将生成的指纹图像与先前登记的指纹图像进行比较。 使用电容型传感器元件作为第一传感器元件,并且使用压敏传感器元件作为第二传感器元件。

    • An image comparing apparatus receives two images to be compared with each other. For each of the two images, respective feature values of partial images in the image are determined. With respect to each partial image in one of the images, the position of a partial image that is in the other image and that has the maximum score of matching with the partial image in that one image is searched for. The search range is limited to partial images selected according to three or five different feature values determined in advance. Then, the similarity score representing the degree of similarity between these two images is calculated, based on information about a movement vector indicating a relation between a reference position for locating the partial image in one image and the maximum matching score position that is searched for with respect to the partial image. Images to be searched belong to the same category as that of the partial image. Here, the images are classified into categories based on the feature values.
    • 图像比较装置接收要彼此比较的两个图像。 对于两个图像中的每一个,确定图像中的部分图像的各自的特征值。 对于其中一个图像中的每个部分图像,搜索位于另一图像中并且具有与该图像中的部分图像匹配的最大分数的部分图像的位置。 搜索范围限于根据预先确定的三个或五个不同特征值选择的部分图像。 然后,基于关于指示用于定位一个图像中的部分图像的参考位置与用于定位一个图像中的部分图像的最大匹配分数位置之间的关系的运动矢量的信息,计算表示这两个图像之间的相似度的相似度分数, 尊重部分图像。 要搜索的图像属于与部分图像相同的类别。 这里,基于特征值将图像分类为类别。
