    • A compound eye imaging apparatus can estimate a sub-pixel disparity with a high degree of accuracy without depending on a brightness of a surface of an object. The compound eye imaging apparatus includes: a standard imaging optical system generating a picture including a standard image; reference imaging optical systems of an even number equal to or larger than two arranged substantially point-symmetrically with respect to the standard imaging optical system, which generate an picture including a reference image; a correlation value calculation unit (6) calculating a correlation value for each shifting amount by which one of the reference images is shifted parallel to a baseline, with respect to the standard image, for each of the reference imaging optical systems of an even number equal to or larger than two; a correlation value addition unit (7) calculating an integrated correlation value by adding, to each corresponding shifting amount, the correlation value calculated for each of said reference imaging optical systems of an even number equal to or larger than two; and a disparity calculation unit (8) calculating a disparity that is a shifting amount resulting in the largest degree of similarity between the standard image and the reference image.
    • 复眼成像装置可以高度准确地估计子像素差异,而不依赖于物体表面的亮度。 复眼成像装置包括:标准成像光学系统,生成包括标准图像的图像; 相对于标准成像光学系统基本上点对称布置的等于或大于2的偶数的参考成像光学系统,其生成包括参考图像的图像; 相关值计算单元,对于每个偶数等于的参考成像光学系统,计算相对于标准图像平行于基准的参考图像之一移动量的相关值 大于或等于2; 相关值相加单元(7),通过将对于每个所述参考成像光学系统计算出的相关值加上等于或大于2的偶数来计算积分相关值; 以及视差计算单元(8),计算作为在标准图像和参考图像之间产生最大相似度的移动量的视差。
