    • A one-dimensional image synthesizing unit 3 images an subject, and produces a plurality of image-to-be-combined signals expressing images-to-be-combined having overlapped regions. A central processing unit 5 first obtains matching of images of the subject for each of adjacent images-to-be-combined for all image-to-be-combined signals by center and large block matching processes, and detects the deviations of overlapped regions from the obtained matching. Next, in a small block matching process, on the basis of the deviations of the overlapped regions, a plurality of reference blocks and search regions are made to correspond to each other and are set in the respective overlapped regions, and the deviations of the images of the subject are detected in a unit of each search region in more detail than the deviations detected by the large block matching process. Finally, each of the images-to-be-combined is partially geometrically deformed so as to cancel the deviation of the image of the subject, the reference block and the search block are made coincident with each other, and all image-to-be-combined signals are combined to superimpose the respective images-to-be-combined, so that combined image signals are obtained.
    • 一维图像合成单元3对被摄体进行成像,并且生成表示具有重叠区域的待组合图像的多个图像组合信号。 中央处理单元5通过中心和大块匹配处理首先获得与待组合的所有图像信号相对应的每个相邻图像的对象的图像的匹配,并且检测重叠区域的偏差 获得匹配。 接下来,在小块匹配处理中,基于重叠区域的偏差,使多个参考块和搜索区域彼此对应并设置在各个重叠区域中,并且图像的偏差 以与大块匹配处理检测到的偏差更详细地检测每个搜索区域的单位。 最后,要组合的每个图像被部分地几何变形,以便消除被摄体的图像的偏差,使得参考块和搜索块彼此一致,并且所有图像将被 组合的信号被组合以叠加要组合的各个图像,从而获得组合的图像信号。

    • An image synthesizing device in which partial images can be rapidly processed (for example, by enlarging, reducing, turning) and synthesized. When synthesizing information for partial images stored in a partial image storage portion is calculated by a synthesizing data calculating portion, accessible rectangular areas, which consist each of a plurality of pixel rows and columns, of partial images stored in the partial image storage portion are accessed one by one by a partial image accessing portion and each of accessed areas is processed by enlarging or reducing or turning on the basis of the calculation results given from the synthesizing data calculating portion. The processed partial images whose areas have been enlarged, reduced or turned, are synthesized by a partial image synthesizing portion on the basis of the synthesizing information, and a synthesized image is stored in a synthesized image storage portion.

    • A picture processing apparatus which can reduce matching errors and shorten a processing time for matching. In the picture processing apparatus, a binarization circuit individually binarizes a pair of object picture signals to generate line picture signals. A feature point extract circuit extracts a plurality of feature point pixels for each reference area in the reference side line picture. A transforming circuit widens a line width of the search side line picture. A correlation computation circuit, for each reference area, finds a correlation between each pixel within a search area in the line picture whose line width has been widened and the feature point pixels. A composition processing section composites the pair of object picture signals based on the correlations. A picture processing apparatus which can adjust density and color tone of two pictures to be composited. At first, the picture processing apparatus finds overlapping areas of the two pictures to be processed and finds typical values typifying distributions of density values of pixels in the overlapping area of each picture, respectively. Next, it adjusts overall lightness of the two pictures by multiplying the density value of each pixel of one picture by a ratio of the typical value of the other picture to the typical value of one picture.
    • 一种能够减少匹配误差并缩短匹配处理时间的图像处理装置。 在图像处理装置中,二值化电路单独地二值化一对物体图像信号以生成线图像信号。 特征点提取电路提取参考侧线图像中的每个参考区域的多个特征点像素。 变换电路拓宽搜索侧线图像的线宽。 对于每个参考区域,相关计算电路找到线宽已经变宽的线条图像中的搜索区域内的每个像素与特征点像素之间的相关性。 合成处理部分基于相关性来合成该对物体图像信号。 一种图像处理装置,其可以调整要合成的两幅图像的浓度和色调。 首先,图像处理装置找到要处理的两个图像的重叠区域,并且分别找到代表每个图像的重叠区域中的像素的浓度值分布的典型值。 接下来,通过将一张图片的每个像素的浓度值乘以另一图像的典型值与一张图像的典型值的比率来调整两张照片的整体亮度。
