    • An imaging apparatus includes: determination means for determining whether a capture image is a frontlit image or a backlit image; detecting means for detecting a flesh-color area in the capture image; calculation means for setting weights, in a luminance histogram on the flesh-color area, on luminance of pixels included in a high-luminance area having a relatively high luminance value and luminance of pixels included in a low-luminance area having a relatively low luminance value in accordance with the determination result, and calculating modified luminance produced by modifying luminance on the flesh-color area on the basis of the weights; and correcting means for correcting brightness of the capture image on the basis of the modified luminance.

    • In an image retrieving apparatus for retrieving a retrieving image in an input image, a color histogram of an image in a retrieving area in the input image is compared with a color histogram of the retrieving image. At first, a candidate area in which the retrieving image can be included is roughly retrieved by rough image retrieving with selecting a larger retrieving area and a rough resolution of gradation of the histograms. Subsequently, an area including an image corresponding to the retrieving image is precisely retrieved by fine image retrieving with a smaller retrieving area and a fine resolution of gradation of the histograms.
    • 在用于检索输入图像中的检索图像的图像检索装置中,将输入图像中的检索区域中的图像的颜色直方图与检索图像的颜色直方图进行比较。 首先,通过选择较大的检索区域和直方图的灰度的粗略分辨率,通过粗略图像检索粗略地检索其中可以包括检索图像的候选区域。 随后,通过用更小的检索区域和直方图的灰度的精细分辨率的精细图像检索精确地检索包括与检索图像相对应的图像的区域。
